# Database 模块
|
||||||
|
|
||||||
|
Database 是 Ayatori 首批实际产品领域之一。第一个迁移切片只建立 PostgreSQL Instance 的纯领域
|
||||||
|
模型，不注册 CRD、不启动 controller，也不访问 PostgreSQL、OpenBao 或 Kubernetes Secret。
|
||||||
|
|
||||||
|
## 来源基线
|
||||||
|
|
||||||
|
完整设计合同及首批领域模型与测试提取自原 PostgreSQL Tenant Operator：
|
||||||
|
|
||||||
|
- 仓库：`git.ddupan.top/panxiao81/postgresql-tenant-operator`
|
||||||
|
- source commit：`dae546e58efa1be81e930861c87f7fb13bb12113`
|
||||||
|
- 原路径：`internal/domain/instance/`、`docs/domain-instance.md`
|
||||||
|
- 迁移日期：2026-09-20
|
||||||
|
|
||||||
|
本目录迁入该基线的 specification、architecture、API、领域、部署、安全、开发、迁移与运维
|
||||||
|
文档，并只进行 Ayatori 产品归属、API group、目录和链接适配；其余已批准行为保持不变。
|
||||||
|
|
||||||
|
迁移只使用该 commit 中已提交的文件。源仓库
|
||||||
|
`feature/instance-extension-observations` 工作树中的 `instance.go` 修改与
|
||||||
|
`instance_extensions_test.go` 未进入本切片。
|
||||||
|
|
||||||
|
代码被移动到 Ayatori 的 `internal/database/domain/instance`，测试 import 和文档链接相应更新；
|
||||||
|
首个后续切片按已批准合同增加 Instance extension observation：观测与当前 target 绑定，进入重新
|
||||||
|
验证或删除时失效，且支持判定不授权 Tenant provisioning。后续 Ready 切片实现管理能力判定、
|
||||||
|
registry 准备决策与完整回读、Ready 重验及本轮 evidence 前置检查；沿用已批准合同，不能把旧运行
|
||||||
|
链路接回该模型。各层验证边界见 [Instance 领域规格](domain-instance.md)。
|
||||||
|
|
||||||
|
## 边界
|
||||||
|
|
||||||
|
- 领域层不依赖 Kubernetes types、数据库 driver 或凭据 provider。
|
||||||
|
- CredentialReference 只携带管理 Secret 的名称与字段映射，不包含 Secret 内容或 OpenBao path。
|
||||||
|
- Instance checkpoint 不是外部事实；实际能力必须由 application/adapter 观察后交给领域对象判断。
|
||||||
|
- 当前代码只检查 Instance 供应前置条件，不授予 Tenant 所有权或外部写入权限，也不表示
|
||||||
|
Database API 已经可用。
|
||||||
|
|
||||||
|
## 管理凭据与连接切片
|
||||||
|
|
||||||
|
`application.InstanceService` 适配自原项目固定基线
|
||||||
|
[`internal/instance/service.go`](https://git.ddupan.top/panxiao81/postgresql-tenant-operator/src/commit/dae546e58efa1be81e930861c87f7fb13bb12113/internal/instance/service.go)，
|
||||||
|
保留 CredentialReader、Connector、Database 的装配边界及串行操作/释放规则。
|
||||||
|
具体连接池完全由 pgxpool v5.11.0 提供，PostgreSQL adapter 不拥有凭据缓存、轮换流程或任意观测回调。
|
||||||
|
|
||||||
|
相对源基线有两项按已批准合同作出的必要修改：管理凭据从固定 controller namespace 的
|
||||||
|
Kubernetes Secret 直接读取；每轮比较有效用户名、密码，检测到变化即关闭旧连接并重新装配。
|
||||||
|
Secret metadata 和无关字段变化不重建连接。观测后再次读取 Secret，中途有效值变化则丢弃结果，
|
||||||
|
不把旧连接的成功作为新凭据有效的证据；这不构成跨 Kubernetes/PostgreSQL 的原子事务。
|
||||||
|
Instance UID、endpoint 或凭据引用变化也会释放旧连接；Forget/Close 只释放本地资源。
|
||||||
|
|
||||||
|
当前通过 `ObserveMetadata` 读取服务器版本和可用扩展，`ObserveVersion` 只是其版本读取便捷入口，
|
||||||
|
不能产生完整 CapabilityObservation 或 Ready。
|
||||||
|
controller 接入、Secret watch、finalizer、registry 观测装配与真实权限检查仍待后续切片；并发 CR 更新
|
||||||
|
必须由调用者通过 resourceVersion 校验。应用层沿用源实现的串行处理，本阶段未引入新的调度框架。
|
||||||
|
|
||||||
|
运行 `make test-database-integration` 验证真实 API server + 一次性 PostgreSQL；fixture 不接受外部
|
||||||
|
DSN，镜像固定摘要，使用随机本机回环端口并在退出时删除测试容器。覆盖缺失/错误凭据、RBAC、
|
||||||
|
namespace 边界、有效值轮换、metadata 无关变化、中途轮换、重建/重试、并发读取、Forget/Close
|
||||||
|
与 TLS DNS/IP SAN、错误 CA/主机名和禁止明文降级。CI 使用 Pod runner 执行，由 runner 提供
|
||||||
|
可用的 Docker，workflow 只做预检、不自行启动 daemon；不依赖 VM。普通 lint 之外还检查
|
||||||
|
integration 标签代码。领域单测、真实 API 行为与真实 PostgreSQL 行为分别验收，不以本切片
|
||||||
|
替代整个 Instance controller 的集成验收。
|
||||||
|
|
||||||
|
## 服务器 metadata 与扩展观测
|
||||||
|
|
||||||
|
SQL adapter 通过一条只读语句读取 `pg_catalog.current_setting('server_version')` 和
|
||||||
|
`pg_catalog.pg_available_extensions`，避免从已安装列表推断可用列表，且不依赖可修改的
|
||||||
|
`search_path`。查询失败丢弃整份结果；成功返回空列表与尚未观察严格区分。
|
||||||
|
参考 PostgreSQL 的 [pg_available_extensions](https://www.postgresql.org/docs/18/view-pg-available-extensions.html)
|
||||||
|
与 [CREATE EXTENSION](https://www.postgresql.org/docs/18/sql-createextension.html) 合同：可用列表
|
||||||
|
表示服务器提供的扩展，不证明管理账号有安装权限，也不保证依赖和其他安装前提满足。
|
||||||
|
|
||||||
|
`InstanceService` 保留原有 CredentialReader → Connector → Database 边界，复用同一个
|
||||||
|
凭据读取、连接刷新和串行释放流程，不新增连接池封装或任意查询回调。每次重新查询 metadata，
|
||||||
|
并在 Secret 有效值回读一致后生成不可变的 `MetadataObservation`，绑定本次 target（含当前
|
||||||
|
generation），不绑定建池时的旧 target。结果不包含凭据，扩展集合不与 driver 的可变 slice 共享。
|
||||||
|
凭据中途变化、读取失败或查询失败时，返回零值观察并释放连接，不复用旧的扩展列表。
|
||||||
|
|
||||||
|
调用方可将 `Target()` 与 `Extensions()` 交给 Instance 的 `ObserveExtensions`；应用调用链
|
||||||
|
仍负责同轮次使用，不能持久化或跨轮缓存这份证据。metadata 读取不安装扩展、不初始化 registry、
|
||||||
|
不设置 Ready，也不授予 Tenant 写权限。管理权限矩阵、registry 完整回读及 controller 的
|
||||||
|
checkpoint/status/finalizer 链路仍是后续切片。
|
||||||
|
|
||||||
|
真实 API server + PostgreSQL 测试验证未安装扩展可被观察、名称保持大小写、search_path 遮蔽
|
||||||
|
不改变查询来源、低权限账号读取、权限撤回失败与恢复、Secret 中途变化丢弃扩展结果。
|
||||||
|
单元测试补充成功空列表、查询附带部分数据时丢弃、结果与可变 slice 隔离、每轮重新读取和
|
||||||
|
generation 变化时的目标绑定；原凭据/TLS/超时/并发测试沿同一 metadata 路径继续运行。
|
||||||
|
|
||||||
|
## Registry 所有权存储切片
|
||||||
|
|
||||||
|
`adapter/postgresql/registry` 直接迁入上述固定基线的 `internal/postgresql/registry`，
|
||||||
|
保留原 schema、版本表和唯一约束，不接回旧 controller。Store 使用调用方提供的 pgx 连接或
|
||||||
|
连接池，不创建连接池、不读取凭据、不管理重连。迁移复用 tern v2.4.3 的事务和 advisory lock，
|
||||||
|
所有权变更复用 PostgreSQL 唯一约束与行锁，没有新增迁移或锁框架。
|
||||||
|
|
||||||
|
Claim 支持相同归属的幂等重试；Retain 保留不可重新占用的墓碑；Delete 仅删除匹配归属的
|
||||||
|
managed 记录，且只应在调用方确认外部资源已删除后调用。Store 本身不删除 database、role
|
||||||
|
或凭据，也不授予 Tenant provisioning 权限。驱动错误仅供内部调用方分类，接入 controller 时
|
||||||
|
仍须按安全合同转换为脱敏的 Condition/Event，不能直接发布原始错误。
|
||||||
|
|
||||||
|
真实 PostgreSQL 测试覆盖重复/并发初始化、唯一约束冲突、并发 Claim、归属不匹配、Retain
|
||||||
|
与 Delete 重试、连接重建、取消恢复、未知 schema/超前版本拒绝，以及真实事务提交后注入
|
||||||
|
客户端失败的恢复分支。后者确定性模拟“提交成功但调用方不知道”，不声称覆盖真实网络分区。
|
||||||
|
registry 尚未装配到 InstanceService；初始化成功不能当作完整 registry 回读或 Instance Ready。
|
||||||
|
controller 重启、Secret watch、finalizer 与跨后端删除仍由后续 envtest/端到端切片验收。
|
||||||
|
|
||||||
|
## 设计入口

|
- [系统规格](specification.md)：规范性行为与验收标准；
|
||||||

- [安全](security.md)、[迁移](migration.md)与[运维](operations.md)；
|
||||||
|
- [部署合同](deployment.md)与[开发测试合同](development.md)。

|
部署和开发文档描述目标合同，其中旧仓库专属的 Make target、脚手架版本和目录尚未接入 Ayatori；
|
||||||
|
在对应实现切片完成前，不应把其中命令理解为当前仓库已经可执行的入口。

| version | `v1alpha1` |
|

|
| 最后更新 | 2026-09-10 |
|
||||||
|
|
||||||
|
本文把已批准的系统规格映射为 CRD 字段合同。API types、生成 CRD、sample 和测试必须与本文
|
||||||
|
一致。Ayatori 尚未注册这些 API，本页是后续实现的规范来源。
|
||||||
|
|
||||||
|
## 通用约定
|
||||||
|
|
||||||
|
- PostgreSQL identifier 匹配 `^[a-z][a-z0-9_]{0,62}$`。
|
||||||
|
- 所有引用名称使用 Kubernetes DNS label/name 的相应校验。
|
||||||
|
- Tenant 的 `spec.instanceRef` 与 `metadata.name` 长度合计不超过 241 个字符，确保派生的
|
||||||
|
`<instanceRef>-<metadata.name>-postgresql` 不超过 Kubernetes DNS subdomain 的
|
||||||
|
253 字符限制。
|
||||||
|
- port、TLS mode、deletion policy 等固定默认值由 CRD defaulting 提供。database、
|
||||||
|
loginRole、Secret 名称等依赖其他字段的值是 controller 语义默认值：字段保持省略，
|
||||||
|
controller 计算 effective value 并通过 status/受管资源展示，不引入 mutating webhook。
|
||||||
|
- 需要读取旧值或跨字段的校验由 CEL 或 controller 完成。
|
||||||
|
- `status` 由 controller 独占写入，禁止出现密码、Token、管理用户名或完整连接串。
|
||||||
|
- 两个 Kind 都只承诺一个 `Ready` Condition；调用方不得依赖内部协调阶段。
|
||||||
|
|
||||||
|
## PostgreSQLInstance
|
||||||
|
|
||||||
|
cluster-scoped，short name 为 `pginstance`。
|
||||||
|
|
||||||
|
### Spec
|
||||||
|
|
||||||
|
| JSON path | 类型 | 必填/默认 | 合同 |
|
||||||
|
| --- | --- | --- | --- |
|
||||||
|
| `spec.endpoint.host` | string | 必填 | PostgreSQL DNS 名；必须被服务端证书 DNS SAN 覆盖 |
|
||||||
|
| `spec.endpoint.hostaddr` | string | 必填 | 单个 IPv4/IPv6；必须被服务端证书 IP SAN 覆盖 |
|
||||||
|
| `spec.endpoint.port` | int32 | `5432` | 1–65535 |
|
||||||
|
| `spec.endpoint.database` | string | `postgres` | 管理连接 database；合法 PostgreSQL identifier |
|
||||||
|
| `spec.endpoint.sslMode` | enum | `verify-full` | `disable`、`require`、`verify-ca`、`verify-full` |
|
||||||
|
| `spec.adminCredentialRef.name` | string | 必填 | controller namespace 内的管理 Secret 名称 |
|
||||||
|
| `spec.adminCredentialRef.usernameKey` | string | `username` | Secret data 中的键名 |
|
||||||
|
| `spec.adminCredentialRef.passwordKey` | string | `password` | Secret data 中的键名 |
|
||||||
|
|
||||||
|
`adminCredentialRef` 不接受 namespace 或 Bao path。管理 Secret 固定在 controller
|
||||||
|
namespace，名称须合法，两个字段须存在且非空。管理员维护 ExternalSecret，由 ESO
|
||||||
|
同步；controller 只读管理 Secret，不创建或修改它。此为 2026-09-13 批准的修订，
|
||||||
|
现有 API types、生成 CRD 和 samples 尚未更新。
|
||||||
|
|
||||||
|
Instance endpoint、管理凭据引用可以修改。修改后 controller 重新验证。
|
||||||
|
2026-09-14 修订：v1alpha1 不实现 allowedExtensions；现有 API types、生成 CRD 和
|
||||||
|
samples 中的字段待后续移除，不作为一个可配置但被忽略的策略保留。
|
||||||
|
扩展请求按目标 PostgreSQL 实际可安装列表判断，可用列表由应用层查询。
|
||||||
|
|
||||||
|
endpoint 由管理员负责，不校验变更前后是否同一物理服务器／registry，只重验新配置
|
||||||
|
的连接与管理能力。新 UID 按新 Instance 处理，不授权接管旧 UID 的 Tenant 资源。
|
||||||
|
|
||||||
|
### Status
|
||||||
|
|
||||||
|
| JSON path | 类型 | 含义 |
|
||||||
|
| --- | --- | --- |
|
||||||
|
| `status.observedGeneration` | int64 | 最近完成有结论协调的 generation |
|
||||||
|
| `status.phase` | enum | `Pending`、`Validating`、`InitializingRegistry`、`Ready`、`Deleting` |
|
||||||
|
| `status.postgresqlVersion` | string | 从 server 回读的版本，不用于客户端解析 |
|
||||||
|
| `status.conditions[]` | `metav1.Condition` | 至少包含唯一的 `Ready` |
|
||||||
|
|
||||||
|
print columns：`Endpoint=.spec.endpoint.host`、`Phase`、`Ready`、`Age`。
|
||||||
|
|
||||||
|
Instance `Ready=True` 要求管理凭据可读、TLS/认证成功、server metadata 可读、registry
|
||||||
|
可访问且权限预检成功。它不代表数据库已经备份或高可用。
|
||||||
|
|
||||||
|
管理凭据从 Kubernetes Secret 装配；已有有效凭据可访问 PostgreSQL 时，Bao／ESO
|
||||||
|
暂时不可用不单独撤销 Instance Ready。Tenant 凭据操作仍依赖 Bao。
|
||||||
|
|
||||||
|
## PostgreSQLTenant
|
||||||
|
|
||||||
|
namespaced，short name 为 `pgtenant`。
|
||||||
|
|
||||||
|
### Spec
|
||||||
|
|
||||||
|
| JSON path | 类型 | 必填/默认 | 合同 |
|
||||||
|
| --- | --- | --- | --- |
|
||||||
|
| `spec.instanceRef` | string | 必填 | cluster-scoped Instance 名称 |
|
||||||
|
| `spec.database` | string | `metadata.name` | 合法 PostgreSQL identifier |
|
||||||
|
| `spec.loginRole` | string | `metadata.name` | database owner 兼应用 login |
|
||||||
|
| `spec.extensions` | set[string] | 空集合 | 必须属于目标实例实际可安装的扩展列表；成功创建后只允许追加 |
|
||||||
|
| `spec.credential.secretName` | string | `<instance>-<name>-postgresql` | 合法的同 namespace ESO target Secret 名称 |
|
||||||
|
| `spec.deletionPolicy` | enum | `Retain` | `Retain` 或 `Delete` |
|
||||||
|
|
||||||
|
Tenant 不声明 OpenBao mount 或 path。controller 使用部署级 mount/base path 和
|
||||||
|
`namespace/name` 推导稳定路径，并用 UID metadata 验证所有权。ExternalSecret 固定为
|
||||||
|
`<instanceRef>-<metadata.name>-postgresql`；目标 Secret 可以由用户指定，只需
|
||||||
|
满足 Kubernetes Secret 名称校验，不限制命名内容；省略时使用相同默认名。
|
||||||
|
|
||||||
|
`instanceRef`、`database`、`loginRole` 和 `credential.secretName` 在首次成功创建外部
|
||||||
|
状态后不可变。
|
||||||
|
`extensions` 只允许集合不变或追加；移除返回 `ImmutableField`，不会执行
|
||||||
|
`DROP EXTENSION`。`deletionPolicy` 在对象进入删除前可以修改；删除开始后以 finalizer
|
||||||
|
首次观察到的值为准，避免清理过程中改变授权范围。
|
||||||
|
|
||||||
|
### Status
|
||||||
|
|
||||||
|
| JSON path | 类型 | 含义 |
|
||||||
|
| --- | --- | --- |
|
||||||
|
| `status.observedGeneration` | int64 | 最近完成有结论协调的 generation |
|
||||||
|
| `status.phase` | enum | controller 状态机的权威 checkpoint |
|
||||||
|
| `status.database` | string | 应用语义默认值后的实际 database 名称 |
|
||||||
|
| `status.loginRole` | string | 应用语义默认值后的实际 owner/login role 名称 |
|
||||||
|
| `status.databaseOID` | uint32 | 回读的 database OID，仅供诊断 |
|
||||||
|
| `status.credential.secretRef.name` | string | 同 namespace 目标 Secret 名称 |
|
||||||
|
| `status.credential.openBaoURL` | string | 完整 KV v2 API URL，不含认证信息 |
|
||||||
|
| `status.conditions[]` | `metav1.Condition` | 至少包含唯一的 `Ready` |
|
||||||
|
|
||||||
|
Secret reference 不重复 namespace，因为它必定与 Tenant 同 namespace。OpenBao URL 格式
|
||||||
|
为 `<consumer-address>/v1/<mount>/data/<derived-path>`；不得包含 Token、用户名、密码或
|
||||||
|
query credential。
|
||||||
|
|
||||||
|
Tenant phase 枚举为 `Pending`、`Planned`、`CredentialCreated`、`RoleCreated`、
|
||||||
|
`DatabaseCreated`、`ExternalSecretCreated`、`CredentialProjected`、`Ready`、`Deleting`。
|
||||||
|
它不包含 `Failed` 或 `Retained`；失败类型由 Condition Reason 表达。
|
||||||
|
|
||||||
|
print columns：`Instance`、`Database`、`Phase`、`Secret`、`Ready`、`Age`。完整 OpenBao URL 只在
|
||||||
|
YAML/JSON status 中输出。
|
||||||
|
|
||||||
|
两个 Kind 的 `status.phase` 都是 controller 状态机的权威 checkpoint。controller 用它
|
||||||
|
选择下一候选动作，但必须在动作前后核对外部事实，不能仅凭 phase 跳过幂等检查。status
|
||||||
|
丢失或领先于实际状态时必须保守重建/纠正。自动化就绪判断仍应读取 `Ready` Condition；
|
||||||
|
phase 用于进度展示、恢复和排障。
|
||||||
|
|
||||||
|
## Condition
|
||||||
|
|
||||||
|
每种类型最多一个 Condition；更新必须保留正确的 `lastTransitionTime` 语义。
|
||||||
|
|
||||||
|
| Reason | Kind | 可重试性 |
|
||||||
|
| --- | --- | --- |
|
||||||
|
| `Reconciling` | 两者 | 正常进行中 |
|
||||||
|
| `Ready` | 两者 | 已收敛 |
|
||||||
|
| `InvalidSpec` | 两者 | 修改 spec 前不会恢复 |
|
||||||
|
| `ImmutableField` | Tenant | 恢复原值或重新迁移 |
|
||||||
|
| `DependencyUnavailable` | 两者 | 自动重试 |
|
||||||
|
| `AuthenticationFailed` | Instance | 修复凭据/TLS 后重试 |
|
||||||
|
| `InsufficientPrivileges` | Instance | 修复管理 role 后重试 |
|
||||||
|
| `InstanceNotReady` | Tenant | Instance 恢复后重试 |
|
||||||
|
| `Conflict` | Tenant | 人工解除名称/所有权冲突 |
|
||||||
|
| `ProvisioningFailed` | Tenant | 按错误类别退避重试 |
|
||||||
|
| `CredentialProjectionFailed` | Tenant | ESO/Secret 恢复后重试 |
|
||||||
|
|
||||||
|
`Ready=True` 必须使用 Reason `Ready`。处理中为 `Unknown/Reconciling`；已知未满足合同为
|
||||||
|
`False`。Condition message 可以包含资源名和错误类别，禁止包含凭据值或完整 Secret。
|
||||||
|
|
||||||
|
## 删除语义
|
||||||
|
|
||||||
|
- `Retain` 不需要等待外部依赖；删除 CR 后外部记录保留原 UID 并标记 unmanaged。
|
||||||
|
- `Delete` 添加 finalizer，严格按规格的所有权验证和清理顺序执行；失败保持 finalizer。
|
||||||
|
- Instance 开始受管时即添加并保存 finalizer；删除时停止新供应，存在 Tenant 引用
|
||||||
|
（包括正在删除的 Tenant）就保留 finalizer，无引用才移除。引用查询失败时继续等待。
|
||||||
|
不级联删除 Tenant 或外部资源；管理员可使用运维逃生流程。
|
||||||
|
- finalizer 不禁止创建 Tenant CR；并发创建者遇到删除中或不存在的 Instance 不得
|
||||||
|
开始供应。首版不增加跨对象锁或准入控制，不承诺跨对象原子删除。

||||||

# 系统架构
|
||||||
|
|
||||||
|
本文是已批准 [`specification.md`](specification.md) 的架构视图。规范定义外部行为，
|
||||||
|
本文解释组件边界；二者冲突时以规范为准。Ayatori Database 模块目前只有首批领域模型，尚未
|
||||||
|
注册 API 或接入运行链路。
|
||||||
|
|
||||||
|
## 组件与数据流
|
||||||
|
|
||||||
|
```text
|
||||||
|
GitOps / kubectl / Terraform / Backstage
|
||||||
|
|
|
||||||
|
v
|
||||||
|
Kubernetes API (CRD)
|
||||||
|
|
|
||||||
|
v
|
||||||
|
Ayatori Database controller
|
||||||
|
| | |
|
||||||
|

|
||||||
|
PostgreSQL DBMS OpenBao KV ExternalSecret
|
||||||
|
catalog+registry |
|
||||||
|
v
|
||||||
|
Kubernetes Secret
|
||||||
|
```
|
||||||
|
|
||||||
|
- Kubernetes `spec` 保存期望状态；`status.phase` 保存 controller 状态机 checkpoint，
|
||||||
|
其他 status 字段保存可重建的观察结果。整个 status 都必须能由外部事实保守恢复。
|
||||||
|
- PostgreSQL catalog 保存 database、role、grant 和 extension 的实际状态。
|
||||||
|
- 两个 CR 的 `status.phase` 是 controller 状态机的权威 checkpoint。
|
||||||
|
- PostgreSQL 管理 database 中的 controller registry 只负责所有权、安装身份和保留标记。
|
||||||
|
- OpenBao KV v2 是应用凭据的事实来源。
|
||||||
|
- External Secrets Operator（ESO）读取 OpenBao，并创建应用使用的 Kubernetes Secret。
|
||||||
|
|
||||||
|
controller 不运行 PostgreSQL/OpenBao，不管理 VM、存储、备份或 OpenBao PKI，也不直接
|
||||||
|
把明文凭据写入 Kubernetes API。
|
||||||
|
|
||||||
|
## 资源模型
|
||||||
|
|
||||||
|
`PostgreSQLInstance` 是 cluster-scoped，由平台管理员创建，描述外部 PostgreSQL 的
|
||||||
|
DNS host、IP host address、端口、管理 database、TLS 模式和管理 Secret 引用。
|
||||||
|
实际可安装扩展由应用层查询后交给领域对象判定，v1alpha1 不实现管理员 allowlist。
|
||||||
|
|
||||||
|
管理连接使用管理员维护的 ExternalSecret 经 ESO 同步到 controller namespace 的
|
||||||
|
Secret；Instance 只选择 Secret 名称与字段，controller 只读，不直接从 Bao 获取
|
||||||
|
管理凭据。Tenant 凭据的创建、读取与销毁仍由 controller 直接访问 Bao。
|
||||||
|
|
||||||
|
`PostgreSQLTenant` 是 namespaced。一个 Tenant 对应一个 database、一个同时作为 owner
|
||||||
|
的 login role、一组只允许追加的 extension、一个由 controller 推导的 OpenBao KV
|
||||||
|
记录，以及同 namespace 的 ExternalSecret 和目标 Secret。
|
||||||
|
|
||||||
|
Tenant namespace 只提供 Kubernetes RBAC 和身份边界。database 与 role 名称在一个
|
||||||
|
Instance 内仍然全局唯一。
|
||||||
|
|
||||||
|
## Reconcile 与所有权
|
||||||
|
|
||||||
|
系统采用最终一致性，不在 Kubernetes、PostgreSQL、OpenBao 和 ESO 之间假装存在分布式
|
||||||
|
事务。每个外部写入前在 CR status 记录阶段，执行幂等操作，回读验证，再推进阶段：
|
||||||
|
|
||||||
|
```text
|
||||||
|
Planned -> CredentialCreated -> RoleCreated -> DatabaseCreated
|
||||||
|
-> ExternalSecretCreated -> CredentialProjected -> Ready
|
||||||
|
```
|
||||||
|
|
||||||
|
controller 每轮同时读取 CR、registry、PostgreSQL catalog、OpenBao metadata 和 ESO
|
||||||
|
投射状态。`status.phase` 是状态机 checkpoint，但不能替代外部回读；丢失或与事实冲突
|
||||||
|
时必须保守重建/纠正。`metadata.generation` 只表示 spec 修改；Condition 的
|
||||||
|
`observedGeneration` 表示该版本是否已经完成一次有结论的协调。
|
||||||
|
|
||||||
|
所有权使用 Instance UID、Tenant UID 与 namespace/name 验证。database/role COMMENT
|
||||||
|
可以辅助排障，但不能代替 registry。未知资源只报告 `Conflict`，不得修改、接管或
|
||||||
|
删除。Retain 后用相同名称重建 CR 会获得新 UID，因此仍然冲突。
|
||||||
|
|
||||||
|
## 创建与删除边界
|
||||||
|
|
||||||
|
创建时先校验全部输入和冲突，再生成一次密码并写入 OpenBao，随后创建 role、database、
|
||||||
|
extension 和 ExternalSecret。只有 ESO 已投射 Secret 且应用凭据实际登录成功，Tenant
|
||||||
|
才可 Ready。
|
||||||
|
|
||||||
|
`Retain` 是默认删除策略，只移除 Kubernetes 管理关系并保留外部资源。显式 `Delete`
|
||||||
|
使用 finalizer，在重新验证所有权后依次删除 ExternalSecret/Secret、连接、database、
|
||||||
|
role、OpenBao KV 历史和 registry。详细恢复与逃生步骤见
|
||||||
|
[`operations.md`](operations.md)。
|
||||||
|
|
||||||
|
## 网络与 TLS
|
||||||
|
|
||||||
|
Instance 同时公布 DNS `host` 和 IP `hostaddr`。PostgreSQL server 证书必须包含对应的
|
||||||
|
DNS SAN 和 IP SAN，消费者自行选择可达目标，并可使用 `verify-full` 验证。OpenBao PKI
|
||||||
|
持有 CA 私钥并签发服务端证书；controller 只挂载公开 CA bundle。
|
||||||
|
|
||||||
|
OpenBao 的 controller 内部地址和外部消费者地址可以不同。Tenant status 同时提供目标
|
||||||
|
Kubernetes Secret reference 和不含认证信息的 OpenBao KV v2 API URL。

| --- | --- |
|
||||||
|
| 状态 | Review |
|
||||||
|
| 环境 | homelab Kubernetes + 外部 PostgreSQL/OpenBao |
|
||||||
|
| 最后更新 | 2026-09-10 |
|
||||||
|
|
||||||
|
本文定义 v1alpha1 的运行依赖、启动顺序和部署级配置。当前 manifests 尚未实现这些
|
||||||
|
配置，示例是后续实现合同，不可直接用于现有脚手架。
|
||||||
|
|
||||||
|
## 依赖与顺序
|
||||||
|
|
||||||
|
1. 准备 PostgreSQL VM、持久盘、备份和网络入口。
|
||||||
|
2. 用 OpenBao PKI 签发 PostgreSQL server 证书，包含 Instance `host` 的 DNS SAN 与
|
||||||
|
`hostaddr` 的 IP SAN；配置 PostgreSQL 强制 TLS。
|
||||||
|
3. 创建 PostgreSQL controller 管理 role 和管理 database 连接权限。
|
||||||
|
4. 在 OpenBao KV v2 写入管理 role 凭据。
|
||||||
|
5. 配置 OpenBao Kubernetes auth、controller policy 和面向 ESO 的读取 policy。
|
||||||
|
6. 安装 ESO，配置独立的管理凭据同步身份和租户凭据读取身份。管理员在 controller
|
||||||
|
namespace 创建管理 ExternalSecret，确认管理 Secret 已同步；另创建供租户使用的
|
||||||
|
`ClusterSecretStore`。
|
||||||
|
7. 创建公开 CA bundle ConfigMap，并挂载到 controller 和需要直接验证数据库的应用。
|
||||||
|
8. 部署 controller，再创建 Instance；等待 Ready 后才创建 Tenant。
|
||||||
|
|
||||||
|
任何一步都不得把真实密码、Token、kubeconfig 或 CA 私钥提交进 Git。
|
||||||
|
|
||||||
|
## Controller 配置合同
|
||||||
|
|
||||||
|
controller 使用以下 CLI flags。必填项缺失、路径无效或 duration 不为正数时，进程必须
|
||||||
|
在启动 manager 前失败；不得等到 reconcile 时才逐个资源报告配置错误。
|
||||||
|
|
||||||
|
| CLI flag | 必填/默认 | 说明 |
|
||||||
|
| --- | --- | --- |
|
||||||
|
| `--openbao-address` | 必填 | controller 可访问的 OpenBao API address |
|
||||||
|
| `--openbao-consumer-address` | 默认同 `--openbao-address` | 写入 Tenant status，必须能被预期外部消费者解析 |
|
||||||
|
| `--openbao-auth-mount` | `kubernetes` | Kubernetes auth mount 名称 |
|
||||||
|
| `--openbao-auth-role` | 必填 | controller ServiceAccount 对应 role |
|
||||||
|
| `--openbao-kv-mount` | `kv` | KV v2 mount；开发可显式用 `secret` |
|
||||||
|
| `--openbao-service-account-token-path` | `/var/run/secrets/kubernetes.io/serviceaccount/token` | Kubernetes auth 使用的投射 token 文件 |
|
||||||
|
| `--openbao-tenant-base-path` | 默认 `postgresql-tenants` | controller 专属 mount-relative 前缀 |
|
||||||
|
| `--external-secret-store-name` | 必填 | controller 创建的 ExternalSecret 固定引用 |
|
||||||
|
| `--postgresql-ca-bundle-path` | PostgreSQL TLS 模式必填 | 只读 PEM trust bundle，不含私钥 |
|
||||||
|
| `--reconcile-timeout` | `30s` | 单轮 reconcile 中外部操作的总期限，必须大于零 |
|
||||||
|
|
||||||
|
address 必须是绝对 `http` 或 `https` URL，不允许 userinfo、query 或 fragment，末尾 `/`
|
||||||
|
在规范化后移除。mount、auth mount 和 base path 都使用 mount-relative path 语义，不以
|
||||||
|
`/` 开头，不含空段、`.` 或 `..`；base path 还不得编码 KV v2 的 `data`/`metadata`
|
||||||
|
API 层。生产环境的 `--openbao-address` 必须使用 HTTPS；HTTP 只用于明确的开发 fixture。
|
||||||
|
|
||||||
|
Tenant 路径固定推导为 `<base-path>/<namespace>/<metadata.name>`。namespace/name 都已通过
|
||||||
|
Kubernetes 名称校验，因此不再允许 CR 提供任意路径。KV v2 API URL 使用 consumer
|
||||||
|
address 拼为 `<address>/v1/<mount>/data/<base-path>/<namespace>/<metadata.name>`。
|
||||||
|
|
||||||
|
base path 必须是合法 mount-relative path，不以 `/` 开头且不包含空段、`.`、`..`、
|
||||||
|
`data`/`metadata` API 层。ExternalSecret 固定命名为
|
||||||
|
`<instanceRef>-<metadata.name>-postgresql`；目标 Secret 可由 Tenant 指定，但名称必须
|
||||||
|
满足 Kubernetes Secret 名称校验，不限制命名内容，默认与 ExternalSecret 同名。
|
||||||
|
|
||||||
|
配置变化不得隐式迁移既有凭据。修改 KV mount/base path 或 consumer address 前必须
|
||||||
|
停止 controller、评估现有 Tenant，并走明确迁移；实现应把 mount/base path 视为安装
|
||||||
|
身份的一部分并在 registry 留存，以便检测错误配置。
|
||||||
|
|
||||||
|
## PostgreSQL 管理 role
|
||||||
|
|
||||||
|
生产部署禁止使用 superuser。管理 role 至少需要：
|
||||||
|
|
||||||
|
- 连接管理 database、读取必要 catalog；
|
||||||
|
- 创建/修改受管 login role；
|
||||||
|
- 创建 database 并指定 owner；
|
||||||
|
- 撤销 `PUBLIC` CONNECT、授予租户 role CONNECT；
|
||||||
|
- 连接租户 database 并创建实例实际支持、租户申请的 extension；
|
||||||
|
- 创建和维护 controller 专属 registry schema/table；
|
||||||
|
- `Delete` 时禁止连接、终止目标 database session、删除已验证归属的 database/role。
|
||||||
|
|
||||||
|
部分 PostgreSQL 操作天然要求较高权限，尤其终止其他 session 和安装某些 extension。
|
||||||
|
应优先使用 PostgreSQL 预定义角色、受控 SECURITY DEFINER 管理函数或限定数据库的
|
||||||
|
授权；任何不得不使用 superuser 的 extension 都必须按实例单独记录，不得扩大默认
|
||||||
|
controller 权限。最终可执行 SQL grant 将随 PostgreSQL adapter 集成测试固化。
|
||||||
|
|
||||||
|
## OpenBao 与 ESO
|
||||||
|
|
||||||
|
controller policy 仅允许在固定 tenant base path 下 create/read/update/delete KV v2
|
||||||
|
data 和 metadata，Delete 必须能永久删除全部版本及 metadata；不读取管理凭据路径。
|
||||||
|
|
||||||
|
管理凭据由管理员维护的 ExternalSecret 同步到 controller namespace；其 ESO 身份
|
||||||
|
只读对应管理路径，不能供 Tenant 使用。租户 ESO 身份只读 tenant base path，不得
|
||||||
|
读取 PostgreSQL 管理凭据。controller 不创建或修改管理 ExternalSecret／Secret。
|
||||||
|
`ClusterSecretStore` 由平台管理员创建，controller 只引用，不创建或修改 Store。
|
||||||
|
controller 创建的 ExternalSecret 与 Tenant 同 namespace，并设置 ownerReference；目标
|
||||||
|
Secret 包含固定七键：`username`、`password`、`database`、`host`、`hostaddr`、`port`、
|
||||||
|
`sslmode`。
|
||||||
|
|
||||||
|
## Kubernetes RBAC
|
||||||
|
|
||||||
|
- controller 可读/写 Instance、Tenant 的 status/finalizer 和 Event。
|
||||||
|
- controller 可在 Tenant namespace 创建、读取、更新、删除 ExternalSecret，并只读检查
|
||||||
|
对应 Secret 是否完成投射。
|
||||||
|
- namespace 用户可以管理本 namespace Tenant，但不能管理 Instance、Store、controller
|
||||||
|
配置或其他 namespace 的 ExternalSecret。
|
||||||
|
- controller 只在自身 namespace 读取所引用管理 Secret 的 data，不获得跨 namespace
|
||||||
|
的管理 Secret 读取权限。Instance 不允许自选 Secret namespace。
|
||||||
|
- 对应用目标 Secret，controller 无需读取 data；验证登录使用从 OpenBao 读取的应用
|
||||||
|
凭据，只检查 Secret 存在性和 ESO 状态。
|
||||||
|
|
||||||
|
## 升级与回滚
|
||||||
|
|
||||||
|
v1alpha1 尚不承诺跨版本转换。升级前备份 CR、PostgreSQL registry 和 OpenBao metadata，
|
||||||
|
先在隔离 Kind 环境运行 E2E。禁止在同一组 CR 上同时运行两个 controller 版本。若新版本
|
||||||
|
在执行任何破坏性迁移前失败，可回滚镜像；涉及 API/storage 或 registry schema 迁移时，
|
||||||
|
必须先写独立升级规格和回滚步骤。
|
||||||
|
|
||||||
|
## 上线验证
|
||||||
|
|
||||||
|
```text
|
||||||
|
PostgreSQL TLS 与备份验证
|
||||||
|
-> OpenBao auth/policy 验证
|
||||||

|
||||||

```
|
||||||
|
|
||||||
|
生产 homelab 上线前还必须完成 [`security.md`](security.md) 的权限检查和
|
||||||
|
[`operations.md`](operations.md) 的备份/逃生检查。

# 开发与测试环境

|
|
||||||
|
> 本页迁入作为 Database 模块的测试分层与 fixture 合同。旧项目的 Make target、devcontainer
|
||||||
|
> 和脚手架版本尚未适配 Ayatori；实现时应复用 Ayatori 现有工具链，并保持这里定义的测试边界。
|
||||||
|
|
||||||
|
## Ayatori 已接入的凭据、metadata 与 registry 切片测试
|
||||||
|
|
||||||
|
本节命令已在 Ayatori 接入；以下历史 Compose/Kind 操作仍属于迁入的目标合同。
|
||||||
|
|
||||||
|
```sh
|
||||||
|
make test
|
||||||
|
make lint
|
||||||
|
make lint-database-integration
|
||||||
|
make test-database-integration
|
||||||
|
```
|
||||||
|
|
||||||
|
最后一项要求本机 Docker 可用。它启动 envtest 的真实 API server/etcd 和固定镜像摘要的临时
|
||||||
|
PostgreSQL 容器，随机绑定回环端口，不读取 kubeconfig，也不接受指向现有数据库的 DSN。
|
||||||
|
每个凭据场景使用独立环境；测试清理仅关闭自己的进程和按确切 ID 删除自己的容器。
|
||||||
|
TLS 测试在临时目录生成一次性证书与私钥，不使用生产 CA。
|
||||||
|
|
||||||
|
当前覆盖固定 namespace 的 Secret 读取与 RBAC、缺失/无效凭据恢复、有效凭据变化后的重连、
|
||||||
|
无关字段更新不重连、中途轮换时丢弃观察、会话重建、并发读取、本地连接释放和 TLS 验证。
|
||||||
|
快速测试、lint 和 Database 集成测试均使用 Pod runner。按维护者于 2026-09-21 更新的接口
|
||||||
|
约定，runner 提供默认可用的 Docker；workflow 通过 `docker version` 和 `docker info` 预检，
|
||||||
|
不自行启动 daemon、不强制 storage driver 或覆盖 Docker endpoint。该约定的 CI 验收依赖
|
||||||
|
runner 后端修复上线，不能从本地测试通过推断远端已经可用。
|
||||||
|
fixture 启动失败会保留退出错误与 stderr，并遮蔽测试密码，
|
||||||
|
以区分缺少命令、daemon 不可达、权限和镜像拉取失败。
|
||||||
|
|
||||||
|
metadata 测试验证版本与可用扩展的只读查询，包括未安装扩展、大小写保持、search_path 遮蔽、
|
||||||
|
低权限账号读取、catalog 访问被撤回后的失败与恢复，以及凭据中途变化时同时丢弃版本和扩展。
|
||||||
|
权限撤回只修改每个场景自建 PostgreSQL 容器的 ACL；不连接现有服务。
|
||||||
|
可用列表不等于安装权限，这些检查不替代后续的完整管理权限矩阵或 Instance Ready 验收。
|
||||||
|
|
||||||
|
registry 测试独立使用一次性 PostgreSQL，不启动 Kubernetes API server。覆盖重复和并发迁移、
|
||||||
|
所有权唯一约束、并发占用、Retain 墓碑与 Delete 幂等、连接重建、取消恢复、未知 schema 与
|
||||||
|
超前版本拒绝。通过在真实 COMMIT 成功后注入客户端错误，验证结果不确定时的重试；这不替代
|
||||||
|
真实网络故障测试，也不覆盖跨后端的删除步骤。
|
||||||
|
|
||||||
|
这些测试尚不包含 Instance CRD/controller、Secret watch、status/finalizer 事件链、registry 观测装配、
|
||||||
|
权限探测矩阵、ESO 或 Tenant 供应。版本查询成功不意味着 Instance Ready。
|
||||||
|
|
||||||
|
本项目同时依赖 Kubernetes API、PostgreSQL、OpenBao 和 ESO。日常开发不连接 homelab
|
||||||
|
中的真实服务：Kubernetes 使用 envtest 或一次性 Kind，另外两个依赖使用一次性
|
||||||
|
容器。这样既避免污染真实数据，也能把启动顺序固化为命令。
|
||||||
|
|
||||||
|
## 是否需要开发 VM
|
||||||
|
|
||||||
|
默认不需要。仓库的 devcontainer 使用独立 Docker-in-Docker daemon，Go 工具链、
|
||||||
|
Kind 节点和依赖容器都与宿主机环境隔离。宿主机只需要能够运行支持 privileged
|
||||||
|
container 的 Docker/Dev Container 环境。
|
||||||
|
|
||||||
|
只有以下情况才建议增加一台可随时重建的开发 VM：
|
||||||
|
|
||||||
|
- 宿主机不允许 privileged devcontainer；
|
||||||
|
- 无法安全使用 Docker socket 或 Docker-in-Docker；
|
||||||
|
- 本机地址段与 Kind/Docker 网络持续冲突；
|
||||||
|
- 需要长期运行、接近 homelab 网络和 TLS 配置的验收环境。
|
||||||
|
|
||||||
|
即使使用 VM，也应在 VM 内继续执行本文相同的容器化流程；不要把 VM 配置成第二套
|
||||||
|
手工维护的开发环境。
|
||||||
|
|
||||||
|
## 环境分层
|
||||||
|
|
||||||
|
| 层次 | Kubernetes | PostgreSQL / OpenBao | 用途 |
|
||||||
|
| --- | --- | --- | --- |
|
||||||
|
| 单元测试 | fake client | fake client | SQL 计划、状态转换和错误分类 |
|
||||||
|
| controller 集成测试 | envtest | fake adapter | CRD、watch、status、finalizer、ExternalSecret 对象 |
|
||||||
|
| adapter 集成测试 | 不需要 | Docker Compose | 真实协议、权限和幂等行为 |
|
||||||
|
| E2E | 一次性 Kind + ESO | Kind 内测试实例 | 凭据投射、TLS、完整网络和删除路径 |
|
||||||
|
|
||||||
|
envtest 只启动 API server 和 etcd，没有 kubelet、scheduler、ESO 或 controller-manager，
|
||||||
|
因此不能用它验证 Deployment、Pod 调度或 Service 网络。此类行为必须留给 Kind
|
||||||
|
E2E。
|
||||||
|
|
||||||
|
## 首次准备
|
||||||
|
|
||||||
|
推荐用支持 Dev Containers 的编辑器打开仓库。devcontainer 会提供 Go、Docker、
|
||||||
|
Kubebuilder、Kind 和 kubectl。脚本固定 Kubebuilder 4.15.0、Kind 0.33.0 和
|
||||||
|
kubectl 1.36.0，与当前脚手架和 Kubernetes Go module 对齐。容器启动后先确认：
|
||||||
|
|
||||||
|
```sh
|
||||||
|
go version
|
||||||
|
docker info
|
||||||
|
kubebuilder version
|
||||||
|
kind version
|
||||||
|
kubectl version --client
|
||||||
|
```
|
||||||
|
|
||||||
|
不要在仓库中保存真实 OpenBao Token、数据库密码或 kubeconfig。Compose 中的
|
||||||
|
`postgres-dev-only` 和 `dev-only-root-token` 是仅绑定回环地址、随容器销毁的公开
|
||||||
|
测试值，不得复制到其他环境。
|
||||||
|
|
||||||
|
## 日常开发的正确顺序
|
||||||
|
|
||||||
|
### 1. 生成并验证纯 Go/Kubernetes 部分
|
||||||
|
|
||||||
|
```sh
|
||||||
|
make manifests generate
|
||||||
|
make test
|
||||||
|
make lint
|
||||||
|
```
|
||||||
|
|
||||||
|
`make test` 会下载与 `go.mod` 中 Kubernetes minor 版本匹配的 envtest 二进制，
|
||||||
|
启动临时 API server/etcd，测试结束后自动关闭。
|
||||||
|
|
||||||
|
规格实现后，快速测试必须覆盖默认值/校验、Condition `observedGeneration`、两个 CR 的
|
||||||
|
status 状态机、不可变字段、extension 只追加、registry 所有权和外部错误分类。envtest 只断言 controller 创建了正确
|
||||||
|
的 ExternalSecret；它不能证明 ESO 已生成 Secret。
|
||||||
|
|
||||||
|
### 2. 启动 PostgreSQL/OpenBao adapter 依赖
|
||||||
|
|
||||||
|
只有开发 PostgreSQL/OpenBao adapter 或完整 reconcile 时才需要：
|
||||||
|
|
||||||
|
```sh
|
||||||
|
make dev-up
|
||||||
|
make dev-smoke
|
||||||
|
```
|
||||||
|
|
||||||
|
启动顺序由 Compose healthcheck 保证：
|
||||||
|
|
||||||
|
1. 创建独立 Compose 网络；
|
||||||
|
2. 启动 PostgreSQL 和 OpenBao；
|
||||||
|
3. 等待 PostgreSQL `pg_isready` 成功；
|
||||||
|
4. 等待 OpenBao `bao status` 成功；
|
||||||
|
5. smoke test 执行 `SELECT 1`；
|
||||||
|
6. smoke test 在 OpenBao dev server 默认的 `secret/` KV v2 mount 写入并读回测试管理
|
||||||
|
凭据。
|
||||||
|
|
||||||
|
本机进程使用以下端点：
|
||||||
|
|
||||||
|
```text
|
||||||
|
PostgreSQL: postgresql://postgres:[email protected]:15432/postgres
|
||||||
|
OpenBao: http://127.0.0.1:18200
|
||||||
|
Token: dev-only-root-token
|
||||||
|
```
|
||||||
|
|
||||||
|
若端口冲突，可以只对当前命令覆盖：
|
||||||
|
|
||||||
|
```sh
|
||||||
|
POSTGRES_DEV_PORT=25432 OPENBAO_DEV_PORT=28200 make dev-up
|
||||||
|
```
|
||||||
|
|
||||||
|
后续执行 `dev-smoke` 和 controller 时必须使用相同端口变量。
|
||||||
|
|
||||||
|
Compose 使用明文 PostgreSQL/OpenBao dev 模式，不覆盖生产 TLS 合同。DNS SAN、IP SAN、
|
||||||
|
Kubernetes auth、最小 policy 和 ESO 必须在 Kind E2E fixture 中验证。
|
||||||
|
|
||||||
|
### 3. 运行针对临时依赖的测试或 controller
|
||||||
|
|
||||||
|
adapter 集成测试通过独立 Make target 执行，不默认塞进快速单元测试：
|
||||||
|
|
||||||
|
```sh
|
||||||
|
make test-integration
|
||||||
|
```
|
||||||
|
|
||||||
|
该 target 会启动一次性 Compose 依赖，并通过 `POSTGRES_TEST_DSN` 把测试指向开发
|
||||||
|
PostgreSQL。registry 测试会删除并重建固定的测试 schema，因此禁止将该变量指向真实
|
||||||
|
homelab database。测试后运行 `make dev-down` 清理依赖。
|
||||||
|
|
||||||
|
Gitea Actions 的 job 本身运行在 Docker container 中，不能通过 `127.0.0.1` 访问
|
||||||
|
Docker host 上发布的 Compose 端口。CI 会暂时将 job container 加入 Compose 网络，
|
||||||
|
并通过 `postgres:5432` 运行集成测试；清理前先断开该网络，才能删除 Compose
|
||||||
|
network。本机执行仍使用默认的 `127.0.0.1:15432`。
|
||||||
|
|
||||||
|
本机运行 controller 时，先确认当前 kubeconfig 指向专用 Kind，而不是真实 homelab：
|
||||||
|
|
||||||
|
```sh
|
||||||
|
kubectl config current-context
|
||||||
|
make setup-test-e2e
|
||||||
|
kubectl config current-context
|
||||||
|
make install
|
||||||
|
make run
|
||||||
|
```
|
||||||
|
|
||||||
|
此时 controller 运行在开发容器内，可以直接访问上面的回环端口。若要验证 Tenant
|
||||||
|
Ready，专用 Kind 还必须安装 ESO、创建测试 ClusterSecretStore，并让 Kind workload
|
||||||
|
能够访问测试 OpenBao。不要把包含
|
||||||
|
`127.0.0.1` 端点的样例部署到 Kind 内；Pod 中的回环地址只指向 Pod 自身。
|
||||||
|
|
||||||
|
### 4. 清理
|
||||||
|
|
||||||
|
```sh
|
||||||
|
make dev-down
|
||||||
|
make cleanup-test-e2e
|
||||||
|
```
|
||||||
|
|
||||||
|
`dev-down` 会删除 Compose volume；所有数据库和 OpenBao dev 数据都应视为一次性。
|
||||||
|
|
||||||
|
## E2E 顺序
|
||||||
|
|
||||||
|
CI 的 E2E 与本机 `make run` 不同：controller 会作为 Pod 运行在 Kind 中。因此完整
|
||||||
|
E2E fixture 必须把测试 PostgreSQL、OpenBao 和 ESO 部署进 Kind，并等待依赖 Ready 后
|
||||||
|
再创建 `PostgreSQLInstance` 和 `PostgreSQLTenant`：
|
||||||
|
|
||||||
|
```text
|
||||||
|
创建 Kind
|
||||||
|
-> 安装 CRD
|
||||||
|
-> 部署 PostgreSQL/OpenBao fixture，签发含 DNS/IP SAN 的测试证书
|
||||||
|
-> 安装 ESO，配置 OpenBao auth/policy 和 ClusterSecretStore
|
||||||
|
-> 等待依赖 Ready 并写入测试管理凭据
|
||||||
|
-> 构建并加载 controller image
|
||||||
|
-> 部署 controller
|
||||||
|
-> 创建 Instance
|
||||||
|
-> 等待 Instance Ready
|
||||||
|
-> 创建 Tenant
|
||||||
|
-> 等待 Tenant Ready
|
||||||
|
-> 验证 registry、PostgreSQL catalog、OpenBao KV、ExternalSecret 和 Secret
|
||||||
|
-> 分别使用 DNS host 与 IP hostaddr 登录
|
||||||
|
-> 删除 Tenant 并分别验证 Retain 与 Delete（含故障点重试）
|
||||||
|
-> 删除 Kind
|
||||||
|
```
|
||||||
|
|
||||||
|
当前 controller 已实现第一条 Instance Ready 纵向链路：E2E fixture 在 Kind 内启动
|
||||||
|
PostgreSQL/OpenBao，配置 Kubernetes auth，验证管理凭据读取、PostgreSQL 登录、registry
|
||||||
|
migration 和 Instance Ready。Tenant provisioning、ESO、TLS DNS/IP SAN 与删除路径仍需
|
||||||
|
后续纵向切片覆盖，不能从 Instance Ready 推断这些合同已经通过。
|
||||||
|
|
||||||
|
## 测试数据与泄漏检查
|
||||||
|
|
||||||
|
- 只使用显眼的固定 canary 测试密码，测试后扫描日志、Event、Condition、metrics 和
|
||||||
|
CR dump，出现 canary 即失败。
|
||||||
|
- 每个最终一致性阶段都注入一次中断，重启后验证密码不变且阶段只向前推进。
|
||||||
|
- 清空、落后或伪造超前的 `status.phase` 后验证它能从外部事实保守恢复/纠正，且不会
|
||||||
|
跳过任何回读。
|
||||||
|
- 为未知同名 database、role、Bao record 和伪造 COMMENT 分别构造 Conflict。
|
||||||
|
- Delete 在每个外部删除步骤失败后重试，确认未误删非当前 UID 资源。
|
||||||
|
- 迁移测试按 [`migration.md`](migration.md) 完整执行，不以单纯 `pg_restore` 成功代替
|
||||||
|
应用读写和回滚验证。
|
||||||
|
|
||||||
|
## 故障排查
|
||||||
|
|
||||||
|
查看依赖状态与日志：
|
||||||
|
|
||||||
|
```sh
|
||||||
|
docker compose -f hack/dev/compose.yaml ps
|
||||||
|
docker compose -f hack/dev/compose.yaml logs postgres openbao
|
||||||
|
```
|
||||||
|
|
||||||
|
如果 envtest 报端口监听失败，通常是当前执行环境禁止监听回环端口，而非 controller
|
||||||
|
失败；在 devcontainer 或允许本机监听的 runner 中执行。若 Kind 无法创建，先运行
|
||||||
|
`docker info`，确认当前用户可以访问 devcontainer 内的 Docker daemon。

# Instance 领域对象规格
|
||||||
|
|
||||||
|
状态：Draft，含已确认决策。日期：2026-09-13。
|
||||||
|
|
||||||
|
上层合并边界见 [ADR-0008](../decisions/0008-merge-postgresql-tenant-operator.md)。本文只展开 Instance，不包含 Tenant 的供应
|
||||||
|
实现，也不新增 CRD 字段。设计签名用于评审职责与行为，不是待复制的 Go 接口代码。
|
||||||
|
|
||||||
|
## 1. 对象职责与生命周期
|
||||||
|
|
||||||
|
Instance 表示一次登记的 PostgreSQL 管理对象，是聚合根。它负责字段与策略校验、
|
||||||
|
根据观察结果判断能力是否满足要求、保护状态转换规则；不登录数据库，不读取 Bao，
|
||||||
|
不查询权限或初始化 registry。
|
||||||
|
|
||||||
|
本草案选择：**领域对象只接收数据并做业务决策，不直接或通过端口、回调访问外部。**
|
||||||
|
应用层调用适配器获取事实、执行被允许的操作，并将观察结果交回对象。Instance 不接收
|
||||||
|
context、客户端或 IO 接口。领域行为不是公共 SetReady：调用方提供事实，不能指定结论。
|
||||||
|
|
||||||
|
每轮从 CR 重建一个 Instance；对象不跨 reconcile 缓存，也不是线程共享单例。
|
||||||
|
管理连接可由装配层跨轮次复用，但连接复用不代表上次能力验证仍然成立。
|
||||||
|
|
||||||
|
身份与 endpoint 以管理员声明为准。改变 endpoint 不验证是否同一物理服务器或
|
||||||
|
registry，不增加安装身份连续性检查；只使旧观察失效，按新配置重验管理能力。
|
||||||
|
新 CR 是新 Instance，不自动获得旧 UID 资源的所有权，也不迁移或清理旧目标。
|
||||||
|
下文“观察绑定匹配”仅指结果属于本轮身份／配置，不是物理服务器身份认证协议。
|
||||||
|
|
||||||
|
## 2. 字段与值对象
|
||||||
|
|
||||||
|
所有可变状态封装在对象内部。构造后身份和本轮 definition 不可变；配置变更通过
|
||||||
|
下一轮装载新的 definition 处理，不提供任意 SetPhase/SetReady/SetEndpoint。
|
||||||
|
|
||||||
|
| 字段 | 类型与内容 | 来源／持久化 | 修改规则 |
|
||||||
|
| --- | --- | --- | --- |
|
||||||
|
| identity | InstanceIdentity：UID、name | CR metadata | 本次对象身份内不可变；同名新 UID 是新对象 |
|
||||||
|
| revision | 正整数，期望配置版本 | metadata.generation | 本轮不可变；不是物理服务器版本 |
|
||||||
|
| definition.endpoint | Endpoint：host、hostaddr、port、managementDatabase、tlsMode | CR spec | 本轮不可变；新配置重验 |
|
||||||
|
| definition.adminCredential | CredentialReference：name、usernameKey、passwordKey | CR spec | 只引用 controller namespace 的管理 Secret，不存明文 |
|
||||||
|
| availableExtensions | 可选的实际可安装扩展集合 | 应用层从目标 PostgreSQL 查询；本轮观察，不新增 status 字段 | 未观察与已观察的空集合不同；目标变化后旧结果失效 |
|
||||||
|
| checkpoint | Pending/Validating/InitializingRegistry/Ready/Deleting | CR status.phase | 只能由领域动作变更，应用层负责持久化 |
|
||||||
|
| observedRevision | 最近完成有结论协调的版本 | CR status.observedGeneration | 成功或已知失败时更新，单纯记录意图不更新 |
|
||||||
|
| readiness | Unknown/Ready/NotReady，加安全失败类别和操作说明 | 由 status Ready Condition 重建，结果再映射回 Condition | 方法更新；不是第二套持久化状态 |
|
||||||
|
| reportedVersion | 可选服务器版本字符串 | status.postgresqlVersion；验证后从服务器更新 | 仅供展示，不能证明连接成功 |
|
||||||
|
| deleting | 是否已请求删除 | metadata.deletionTimestamp 映射 | 本轮不可变；优先于其他动作 |
|
||||||
|
| evidence | 可选 CapabilityEvidence | 本轮外部回读；不新增 status 字段 | 重建时始终为空，不能从 Ready Condition 伪造 |
|
||||||
|
|
||||||
|
Endpoint 的构造约束沿用 API：非空 host、合法 IP、1–65535 端口、合法 PostgreSQL
|
||||||
|
identifier、显式 TLS mode，禁止隐式降级。CredentialReference 包含合法 Secret 名称
|
||||||
|
及非空字段名，不包含 namespace 或 Bao path；namespace 由应用层固定为 controller
|
||||||
|
自身 namespace。这里校验领域值，不在对象里校验整个 controller 部署配置。
|
||||||
|
|
||||||
|
CapabilityEvidence 包含本轮目标绑定（Instance UID、revision、endpoint、凭据引用）、
|
||||||
|
server version、管理能力检查结果、registry 观察结果。registry 结果区分
|
||||||
|
Absent/NeedsMigration/Usable；连接失败不能当作 Absent。它不包含密码、token 或 DSN。
|
||||||
|
|
||||||
|
管理能力要求来自规格中的 role/database/grant/extension 操作，不等价于“能执行
|
||||||
|
SHOW server_version”。具体权限探测矩阵需在 PostgreSQL 适配器规格中定义，不能
|
||||||
|
让一个没有定义检查内容的布尔值承担验收。
|
||||||
|
|
||||||
|
不属于 Instance 的字段：Tenant 清单、客户端、连接池、token TTL、CA 文件句柄、
|
||||||
|
Kubernetes resourceVersion。resourceVersion 留在应用层作为乐观并发保存的前提。
|
||||||
|
|
||||||
|
### 扩展支持判定（2026-09-14 已确认方向）
|
||||||
|
|
||||||
|
v1alpha1 按目标 PostgreSQL 实际可安装的扩展列表判断请求，不实现管理员 allowlist。
|
||||||
|
allowlist 仅保留为后续可选策略，不接受一个看似生效、实际被忽略的策略字段；现有
|
||||||
|
CRD 的 allowedExtensions 应在对应 API 改动中移除，本次只修订文档。
|
||||||
|
|
||||||
|
应用层查询实际可用扩展并提供与本轮目标绑定的观察；Instance 只做集合判断，不
|
||||||
|
访问数据库。不沿用之前提议的字符正则，不自动改大小写或名称；SQL 适配器仍须
|
||||||
|
安全引用 identifier。可用列表不是已安装列表，也不保证权限或其他安装前提满足。
|
||||||
|
|
||||||
|
未观察／查询失败不得当作空集合或不支持；不得用旧目标的列表授权新目标的操作。
|
||||||
|
非空请求须属于已观察的可用集合，返回不支持的名称；空请求无需扩展支持判定，
|
||||||
|
但不绕过 Instance 的其他就绪要求。安装后仍需回读，不能以集合匹配代替安装验证。
|
||||||
|
列表变化不触发自动卸载；已有扩展的漂移处理留到 Tenant 用例细化。
|
||||||
|
|
||||||
|
## 3. 设计签名
|
||||||
|
|
||||||
|
```text
|
||||||
|
Reconstitute(identity, revision, definition, checkpointSnapshot, deleting)
|
||||||
|
-> Instance | InvalidDefinition
|
||||||
|
|
||||||
|
Instance.BeginValidation() -> Outcome
|
||||||
|
Instance.AssessManagement(observation: CapabilityObservation) -> Outcome
|
||||||
|
Instance.PlanRegistryPreparation(observation: CapabilityObservation)
|
||||||
|
-> AlreadyUsable | PreparationAllowed | PreparationDenied
|
||||||
|
Instance.AssessRegistryResult(result: RegistryPreparationResult) -> Outcome
|
||||||
|
Instance.AssessReadiness(observation: CapabilityObservation) -> Outcome
|
||||||
|
Instance.CheckExtensions(requested: ExtensionSet)
|
||||||
|
-> Accepted | ExtensionsUnsupported | ExtensionSupportUnobserved
|
||||||
|
Instance.RequireProvisioningReady() -> Accepted | InstanceNotReady
|
||||||
|
Instance.BeginDeletion() -> Outcome
|
||||||
|
Instance.Snapshot() -> InstanceSnapshot
|
||||||
|
```
|
||||||
|
|
||||||
|
Outcome 是正常推进、已知失败或方法前提不成立，不包含重试秒数、Kubernetes patch
|
||||||
|
或原始驱动错误。InstanceSnapshot 只包含 checkpoint、observedRevision、readiness、
|
||||||
|
reportedVersion，不能序列化 evidence。快照与集合访问返回值副本。
|
||||||
|
|
||||||
|
CapabilityObservation 是不可变的事实输入：目标绑定、服务器版本、管理能力检查项和
|
||||||
|
registry 观察结果；各检查项区分成功、失败、未观察，未观察不视为成功。失败只含安全
|
||||||
|
类别，不含驱动异常或凭据。对象校验目标绑定与当前身份／配置一致，拒绝不匹配输入，
|
||||||
|
不改变状态；完整性不足不能产生 Ready。观察结果由应用层收集，对象不能自行证明
|
||||||
|
这些事实的真实性或实时性；采集来源、同轮次关联和并发检查由应用层保证。
|
||||||
|
|
||||||
|
RegistryPreparationResult 为操作失败（目标绑定、安全失败类别）或操作后的完整回读
|
||||||
|
观察。单独的“迁移调用成功”不是就绪证据。CapabilityEvidence 是对象接受并判定满足
|
||||||
|
要求的观察值，不是调用方传入的 Ready 布尔值。
|
||||||
|
|
||||||
|
### 构造与恢复
|
||||||
|
|
||||||
|
Reconstitute 校验期望 definition；无效输入不构造一个可参与用例决策的 Instance。
|
||||||
|
入口把 InvalidDefinition 映射成 InvalidSpec，不必为了报告坏 CR 而制造非法领域对象。
|
||||||
|
checkpoint 缺失或未知时保守使用 Pending；reportedVersion 和 Ready 都只是旧观察，
|
||||||
|
evidence 为空。若 observedRevision 与 revision 不一致，旧 Ready 不得通过供应检查。
|
||||||
|
|
||||||
|
### 方法合同
|
||||||
|
|
||||||
|
| 方法 | 前置条件／输入 | 行为与状态变化 | 失败语义 |
|
||||||
|
| --- | --- | --- | --- |
|
||||||
|
| BeginValidation | 未删除；初次登记、配置变更或需重建 checkpoint | 转 Validating，readiness=Unknown，清空 evidence；不做外部 IO，不推进 observedRevision | deleting 时不启动验证 |
|
||||||
|
| AssessManagement | 未删除；Validating；目标匹配的观察 | 判定管理访问、metadata、权限是否满足；registry 可用或可安全准备时转 InitializingRegistry，仍为 Unknown；不执行探测 | 失败保持 Validating，NotReady，observedRevision=当前版本 |
|
||||||
|
| PlanRegistryPreparation | 未删除；InitializingRegistry；本轮前置观察 | 根据管理能力及 registry 现状决定无需写入、允许准备或禁止准备；返回决策，不执行迁移、不标 Ready | 访问失败、不兼容或证据不足时禁止写入，NotReady；保持阶段，更新 observedRevision |
|
||||||
|
| AssessRegistryResult | 未删除；InitializingRegistry；准备结果或无需写入时的完整回读 | 按全部就绪条件判断回读结果；全满足才 Ready，并更新 observedRevision/version/evidence | 操作失败或回读不满足时保持 InitializingRegistry、NotReady；不得提前 Ready |
|
||||||
|
| AssessReadiness | 未删除；Ready；本轮观察 | 配置版本不一致时仅 BeginValidation；否则根据全部观察判断是否仍满足就绪条件 | 访问失败转 Validating/NotReady；registry 缺失或需迁移时转 InitializingRegistry，保存后下一轮修复 |
|
||||||
|
| CheckExtensions | 请求集合；本轮实际可用扩展观察 | 判断请求是否为实际可用集合的子集，返回不支持的名称；无 IO、无状态修改 | ExtensionsUnsupported 或 ExtensionSupportUnobserved；不卸载已存在扩展 |
|
||||||
|
| RequireProvisioningReady | 供 Tenant 用例使用 | 要求未删除、Ready、observedRevision 匹配，并有本次调用链的新鲜完整 evidence | 不满足即 InstanceNotReady；持久化 Ready 本身不构成授权 |
|
||||||
|
| BeginDeletion | deleting=true | 转 Deleting，清除供应能力，Unknown；不执行任何数据库或凭据删除 | 引用检查／finalizer 处理失败不得恢复成可供应 |
|
||||||
|
| Snapshot | 任意合法对象状态 | 返回可安全持久化的结果值 | 不触发 IO，也不改变状态 |
|
||||||
|
|
||||||
|
领域方法只检查对象状态，不知道 checkpoint 是否已落盘。“已持久化 checkpoint”是
|
||||||
|
应用用例执行外部写入的前提。内存字段变成 InitializingRegistry 不代表已保存成功；不能
|
||||||
|
在同一轮无条件接着执行迁移。通过用例测试验证此约束，而不是伪造一个内存事务。
|
||||||
|
|
||||||
|
AssessManagement 成功只是中间步骤，observedRevision 不前移；完成就绪判定或
|
||||||
|
明确失败才产生相应有结论结果。旧版本字符串可供诊断，但失败会清空 evidence。
|
||||||
|
|
||||||
|
Instance 不在本轮暴露 CreateDatabase/DeleteDatabase：Tenant 的供应／销毁授权来自
|
||||||
|
Tenant 和 OwnershipClaim，不是从 Instance.Ready 推导。数据库执行能力如何承接
|
||||||
|
已授权动作，留到 Tenant 对象规格，不在这里设计第二个万能 service。
|
||||||
|
|
||||||
|
## 4. 应用层与外部访问边界
|
||||||
|
|
||||||
|

|
||||||

EnsureRegistry(context, target) -> Completed | AccessFailure
|
||||||
|
```
|
||||||
|
|
||||||
|
应用层在 IO 前绑定目标并关联结果，领域对象在接受观察时检查身份和配置匹配；旧
|
||||||
|
endpoint 的成功结果不得用于新 endpoint。Inspect 是只读；EnsureRegistry 是幂等初始化／迁移，
|
||||||
|
不能顺带建立 Tenant 数据库或接管未知 schema。Completed 不足以推进 Ready，必须回读。
|
||||||
|
|
||||||
|
适配器由装配层绑定管理连接；Secret 读取与连接池释放留在该边界之后，Instance
|
||||||
|
管理连接不涉及 Bao token。适配器不得把基础设施异常转换成 Ready。失败区分依赖不可用、
|
||||||
|
认证失败、权限不足和 registry 不兼容；不兼容属于不可安全继续，不自动覆写。
|
||||||
|
registry 不兼容的具体 Condition 映射须在接口规格中确定，不能统一误报权限不足。
|
||||||
|
|
||||||
|
管理连接由应用层从 controller namespace 的 Secret 装配；管理员维护 ExternalSecret，
|
||||||
|
ESO 负责同步。Instance 路径不直接访问 Bao，也不以 Bao／ESO 当前可用性作为就绪条件。
|
||||||
|
首次装配缺少有效 Secret 时失败；已有凭据可正常访问 PG 时继续按 PG 能力判定。
|
||||||
|
检测到所引用 Secret 的有效用户名或密码变化时，应用／基础设施层使用新值重建连接池
|
||||||
|
并重新采集管理能力观察；metadata 或无关字段变化不重建。不要求 Instance generation
|
||||||
|
变化，也不能复用旧连接的成功观察来证明新凭据有效。Secret 变化监听、连接释放和
|
||||||
|
刷新均不进入领域对象；应用层保证旧连接观察不混入刷新后的调用链。
|
||||||
|
controller 不修改 PostgreSQL 密码、不回写 Secret 或 Bao 管理凭据。
|
||||||
|
|
||||||
|
## 5. 状态转换与初始化走查
|
||||||
|
|
||||||
|
```text
|
||||||
|
Pending --BeginValidation/保存--> Validating
|
||||||
|
Validating --AssessManagement(观察)/保存--> InitializingRegistry
|
||||||
|
InitializingRegistry --AssessRegistryResult(回读结果)/保存--> Ready
|
||||||
|
Ready --配置变化或访问失败/保存--> Validating
|
||||||
|
Ready --registry 需修复/保存--> InitializingRegistry
|
||||||
|
任意阶段 --删除请求/保存--> Deleting
|
||||||
|
```
|
||||||
|
|
||||||
|
1. 入口读取 CR，装配 definition、checkpointSnapshot；客户端不注入领域对象。
|
||||||
|
2. 应用层按 checkpoint 协调用例；首次调用 BeginValidation，没有 IO。
|
||||||
|
3. 保存 Validating。若保存失败，结束本轮，不执行 registry 写入。
|
||||||
|
4. 下一轮应用层调用适配器探测实例，将观察交给 AssessManagement；领域判定通过后
|
||||||
|
保存 InitializingRegistry，保存失败则停止，不进行迁移。
|
||||||
|
5. 再下一轮应用层采集前置观察，调用 PlanRegistryPreparation。仅在意图已持久化且
|
||||||
|
领域允许时调用 EnsureRegistry；AlreadyUsable 则跳过写入，PreparationDenied 则
|
||||||
|
保存失败结果并停止。允许的操作完成后回读，交给 AssessRegistryResult 决定能否
|
||||||
|
Ready；操作失败也用安全结果交回，不在应用层直接修改 phase。
|
||||||
|
6. 入口用原 resourceVersion 前提保存快照；并发变更导致冲突时重新装载，不覆盖新状态。
|
||||||
|
7. 后续 Ready 检查先由应用层探测，再调用 AssessReadiness；Tenant 用例同样获取当前事实，不能
|
||||||
|
仅凭另一个 CR 的 Ready Condition 永久缓存授权。实际资源写入仍须处理并发变化。
|
||||||
|
|
||||||
|
阶段调度和外部操作顺序在应用层；“观察是否满足业务要求、是否允许准备 registry、
|
||||||
|
哪些结果算完成、失败退到哪里”在 Instance 方法内。controller 不重复这些规则，
|
||||||
|
也不直接把 phase 设置成 Ready。领域允许操作并不锁住外部世界，适配器仍须保障幂等
|
||||||
|
和并发安全；禁止把旧观察当成永久授权。
|
||||||
|
|
||||||
|
## 6. 不变量与恢复验收
|
||||||
|
|
||||||
|
- UID 不随名称复用；不同 UID 的 evidence/结果不可互用。
|
||||||
|
- 未完成当前配置的能力回读，不能新产生 Ready，也不能通过供应检查。
|
||||||
|
- checkpoint 可以落后或被伪造；每次初始化／供应前都核对事实。status 清空只需重新
|
||||||
|
验证和幂等准备，不删除 registry，更不能重新生成 Tenant 密码。
|
||||||
|
- 迁移成功而 status 保存失败：重试回读已存在 registry，安全完成，不重复破坏性写入。
|
||||||
|
- registry 在 Ready 后消失：下一次回读撤销 Ready，保存修复意图后才能重新准备。
|
||||||
|
- 外部 IO 超时：产生安全失败结果；保存 status 使用仍有效的外层上下文，不能复用
|
||||||
|
已超时的 IO 上下文而丢失失败状态。
|
||||||
|
- 已请求删除的 Instance 不允许新供应；BeginDeletion 不删除 PostgreSQL、Tenant 或
|
||||||
|
Bao。应用层在开始受管时添加并保存 finalizer，而非出现 Tenant 后再添加。
|
||||||
|
删除时查询所有引用它的 Tenant（含删除中的对象）；有引用或查询失败就保留
|
||||||
|
finalizer，确认无引用才移除。引用查询、finalizer 写入和本地连接释放均不属于
|
||||||
|
领域 IO，Instance 只根据删除请求禁用供应能力。
|
||||||
|
- 首版不为 Instance 删除增加跨对象锁或准入控制。并发创建的 Tenant CR 不被
|
||||||
|
finalizer 拦截，但遇到删除中／不存在的 Instance 不得开始供应；不承诺取消
|
||||||
|
已在途的外部操作，也不声称引用查询与移除 finalizer 是跨对象原子事务。
|
||||||
|
- CheckExtensions 失败不能授权扩展安装；可用列表变化不会自行卸载已有扩展。
|
||||||
|
- Snapshot、错误、日志和领域对象格式化不输出明文凭据或 token。
|
||||||
|
- 领域测试只提供观察值，无需数据库、网络、context 或 IO mock；相同状态和输入
|
||||||
|
得到相同决策。缺少检查项、目标不匹配和旧配置结果不得产生 Ready。
|
||||||
|
|
||||||
|
上述每条都对应领域或用例测试；真实权限检查、迁移与并发保障由适配器集成测试
|
||||||
|
验证。本文为设计文档，未执行或宣称通过这些测试。
|
||||||
|
|
||||||
|
## 7. 本轮待评审与后续阻塞项
|
||||||
|
|
||||||
|
本轮请先确认字段归属、应用层采集事实／Instance 纯决策的分工、方法与状态转换合同。
|
||||||
|
管理 Secret 来源、Bao 故障不单独撤销 Instance Ready，以及管理用户名／密码变化时
|
||||||
|
重建连接池，以及管理员声明的 Instance 身份／endpoint 和简化 finalizer 删除规则
|
||||||
|
均已确认。其他决策及未决项见总体草案，不增加后台清扫器或状态字段。
|
||||||
|
|
||||||
|
批准本对象结构不等于批准这些未决行为，也不意味着立刻实现完整供应链路。
|
||||||
|
|
||||||
|
## 8. 领域实现与验证边界（2026-09-21）
|
||||||
|
|
||||||
|
`internal/database/domain/instance` 按上述方法合同实现 Ready 纯判定。输入分别表达连接、
|
||||||
|
metadata、role、database、grant、extension 管理能力，以及 registry 的未观察、缺失、需迁移、
|
||||||
|
可用、不兼容和不可访问状态。检查零值或未知值按证据不足处理；操作失败只使用封闭的安全
|
||||||
|
类别，不接收驱动错误。`Snapshot.Failure` 是 Condition 映射的领域输入，不新增 CRD/status 字段。
|
||||||
|
|
||||||
|
管理能力分别指目标连接可用、服务器 metadata 可读，以及执行规格 §7 所要求的角色、数据库、
|
||||||
|
授权和扩展管理操作的能力；不是仅凭版本查询或扩展可用列表判定权限。具体 SQL 权限探测矩阵、
|
||||||
|
最小权限角色和扩展权限例外仍须在 PostgreSQL adapter 切片定义并用真实后端验证。
|
||||||
|
registry 不兼容独立保留为领域失败类别，不将其误报为权限不足；公开 Condition Reason 的映射
|
||||||
|
留待 API/application 切片按原合同评审。
|
||||||
|
|
||||||
|
领域测试验证完整回读、缺少检查项、状态重建、重复判定、目标不匹配、配置变化、依赖失败、
|
||||||
|
registry 丢失／不兼容、操作结果不确定和删除限制。只有本轮完整能力判定通过后，Instance
|
||||||
|
前置条件检查才通过；这不授予 Tenant 所有权，也不替代实际写入前的并发校验。
|
||||||
|
|
||||||
|
本切片不新增 controller、adapter、Secret 读取或外部生命周期操作。checkpoint 保存失败、
|
||||||
|
resourceVersion 冲突、watch 与 finalizer 事件链需由后续 application/envtest 验证；SQL 探测、
|
||||||
|
registry 初始化／迁移、超时后的真实状态回读和并发幂等由 PostgreSQL 集成测试验证；Secret
|
||||||
|
变化后的连接刷新由 Kubernetes API 加真实 PostgreSQL 的集成测试验证。纯领域测试不能证明
|
||||||
|
Database 已可运行或这些集成合同已完成。

# 领域模型设计草案
|
||||||
|
|
||||||
|
状态：Draft，含已确认决策。日期：2026-09-13。
|
||||||
|
|
||||||
|
本文定义领域职责、身份与一致性边界，并用对象规格细化字段和方法合同；方法使用
|
||||||
|
设计签名，不固定 Go 目录、SDK 或框架，也不批准实现。外部行为以
|
||||||
|
[系统规格](specification.md) 为准；下列未决问题不能由实现自行决定。
|
||||||
|
PR #6 的代码和已有 registry 表结构是可评估的实现素材，不反向决定领域模型。
|
||||||
|
|
||||||
|
## 1. 领域与统一语言
|
||||||
|
|
||||||
|
本系统的领域是“在共享 PostgreSQL 上供应并管理应用租户”，不是数据库服务器运维。
|
||||||
|
v1alpha1 先采用一个限界上下文，不把 PostgreSQL、Bao、Kubernetes 各自当成业务上下文。
|
||||||
|
|
||||||
|
| 术语 | 含义 | 不是什么 |
|
||||||
|
| --- | --- | --- |
|
||||||
|
| Instance | 平台登记的外部 PostgreSQL 管理对象及其供应策略 | 连接池、VM 或 controller 单例 |
|
||||||
|
| Tenant | 一个应用的数据库使用合同及受管资源生命周期 | PostgreSQL database 的别名 |
|
||||||
|
| Database | 租户数据库的名称、owner、扩展等期望描述与实际观察 | 包含 Bao 登录与连接关闭的操作接口 |
|
||||||
|
| LoginRole | 同时作为 database owner 和应用登录身份的角色 | 额外的 NOLOGIN owner |
|
||||||
|
| OwnershipClaim | 某个 Tenant 身份对一组资源名称与凭据位置的所有权声明 | 工作流阶段或仅凭名称推断的归属 |
|
||||||
|
| CredentialLocation | 固定推导的凭据位置及所有权关联 | 密码本身或用户可任意选择的 KV path |
|
||||||
|
| CredentialProjection | 把既定凭据交付到目标 Secret 的要求与观察结果 | controller 直接写入明文 Secret |
|
||||||
|
|
||||||
|
UID 表示一次 Kubernetes 对象身份；namespace/name 用于定位，不足以证明归属。
|
||||||
|
database OID 是诊断观察值，不充当本系统的租户身份。
|
||||||
|
|
||||||
|
## 2. 候选聚合边界
|
||||||
|
|
||||||
|
### Instance：实例能力与供应策略
|
||||||
|
|
||||||
|
Instance 是候选聚合根，持有自身身份、endpoint、管理凭据引用、实际可用扩展观察，
|
||||||
|
以及用于判断当前能力的观察结果。它不持有所有 Tenant 对象的集合。
|
||||||
|
|
||||||
|
其行为包括：
|
||||||
|
|
||||||
|
- 判断租户申请的 extension 是否在本实例实际可安装列表中；v1alpha1 暂不实现 allowlist。
|
||||||
|
- 根据管理连接、服务器信息、registry 和权限检查结果判断是否具备供应能力。
|
||||||
|
- 判断配置变化使哪些能力观察过期，禁止以旧 generation 的 Ready 证明新配置可用。
|
||||||
|
- 在 registry 初始化完成并回读验证后，接受新的就绪结果。
|
||||||
|
|
||||||
|
“探测实例”“准备管理 registry”是应用用例协调的外部操作，不是 Instance 的 IO 方法。
|
||||||
|
领域对象只接收观察值，负责前提、规则和状态决策；应用层调用适配器获取事实与执行
|
||||||
|
获准操作。领域对象不持有或调用外部访问端口、客户端或回调。具体选择见
|
||||||
|
[Instance 字段与行为](domain-instance.md)，仍处于待评审状态。
|
||||||
|
|
||||||
|
### Tenant：供应合同与资源生命周期
|
||||||
|
|
||||||
|
Tenant 是另一个候选聚合根，通过身份引用 Instance，而不是 Instance 的聚合成员。
|
||||||
|
操作一个 Tenant 不应要求装载、锁定或保存整个实例的租户集合。
|
||||||
|
|
||||||
|
Tenant 持有有效的 database/role 名称、请求的扩展、凭据交付目标、删除策略，以及
|
||||||
|
已建立的资源绑定。它负责：
|
||||||
|
|
||||||
|
- 检查绑定后的不可变字段、extension 只追加规则。
|
||||||
|
- 判断外部部分状态属于本 Tenant、尚不存在，还是与未知资源冲突。
|
||||||
|
- 决定是否允许继续供应、何时达到 Ready、是否允许释放受管资源。
|
||||||
|
- 按 Retain/Delete 合同限制行为，禁止把保留资源自动认领给同名新 UID。
|
||||||
|
|
||||||
|
Database、LoginRole 和 CredentialProjection 暂不设独立聚合根或独立 CRUD 用例。
|
||||||
|
它们可作为 Tenant 内的资源描述与观察值；有规则才增加行为，不为了“充血”添加方法。
|
||||||
|
真实 PostgreSQL database/role 的存在不意味着内存中必须各有一个有身份的实体。
|
||||||
|
|
||||||
|
聚合边界是业务规则的保护边界，不表示 Tenant 对应的 PostgreSQL、Bao、ESO 资源
|
||||||
|
能够一次事务提交。跨系统供应必须允许部分完成。
|
||||||
|
|
||||||
|
### OwnershipClaim：跨租户唯一性与持久证据
|
||||||
|
|
||||||
|
名称唯一性不可能只靠某个 Tenant 的内存检查保证。需要一项领域能力，在持久化边界
|
||||||
|
原子认领资源；已有 registry 是其适配器候选，仍需结合 catalog 和 Bao metadata 检查。
|
||||||
|
|
||||||
|
Claim 与 Tenant 关联，但不随 Tenant CR 消失：Retain 后证据必须继续存在。因此不能
|
||||||
|
把它仅视为 CR 的附属 status。是否作为独立的小聚合，先以“可独立持久化、保留并保护
|
||||||
|
归属不变量的声明”建模；不因此引入新的 CRD。
|
||||||
|
|
||||||
|
- 同一身份、同一绑定的重复认领可以成功；不同 UID 或不同绑定不能覆盖。
|
||||||
|
- Claim 预留名称不等于证明同名外部资源由本 controller 创建。
|
||||||
|
- 实际写入仍须核对所有权，不能把先查后建当成并发安全保证。
|
||||||
|
- 当前 registry 的数据库事务不能覆盖 Bao；跨实例的凭据路径竞争也不能靠单个
|
||||||
|
registry 的唯一约束解决。写入前提与条件创建协议需单独设计和验收。
|
||||||
|
|
||||||
|
## 3. 领域、用例与适配器的分工
|
||||||
|
|
||||||
|
| 层 | 承担的职责 | 禁止承揽的职责 |
|
||||||
|
| --- | --- | --- |
|
||||||
|
| 领域对象／策略 | 身份、有效合同、归属判断、允许的动作、完成条件 | 外部 IO（包括通过接口间接调用）、解析 CLI、生成 Kubernetes Condition |
|
||||||
|
| 应用用例 | 装载模型与事实、持久化意图、调用能力、回读、提交结果 | 另写一套绕过领域规则的判断流程 |
|
||||||
|
| controller 入口 | CR 映射、调度、watch、重试、status/finalizer 写入 | 在 reconcile 中重新定义业务规则 |
|
||||||
|
| 基础设施适配器 | PostgreSQL、registry、Bao、ESO 的实际读写与并发保障 | 自行决定接管、改密码或扩大删除范围 |
|
||||||
|
| 启动装配 | 校验部署配置，创建共享客户端、连接管理器及用例依赖 | 把连接生命周期当成 Instance 的业务状态 |
|
||||||
|
|
||||||
|
领域可使用独立的身份、endpoint、identifier、extension 集合等值对象，不依赖 CRD
|
||||||
|
类型、pgx pool 或 Bao SDK。Kubernetes 对象的存取与 registry 的存取不是一个通用
|
||||||
|
`Save(Tenant)` 可以原子完成的事情；不虚构跨系统 Unit of Work。
|
||||||
|
|
||||||
|
暂不引入事件总线、事件溯源、通用聚合框架或全套 Repository CRUD。领域建模的依据
|
||||||
|
是业务规则，而不是接口和目录数量。
|
||||||
|
|
||||||
|
## 4. 状态与恢复
|
||||||
|
|
||||||
|
CR `status.phase` 仍是已批准的工作流 checkpoint，不在内存对象或 registry 再建一套
|
||||||
|
权威 phase。领域对象可以由 CR 的期望状态、checkpoint 和外部观察重新构造。
|
||||||
|
|
||||||
|
phase 只决定候选步骤，外部证据决定该步骤是否允许执行、是否已经完成。应用层在
|
||||||
|
写操作前保存意图，调用幂等操作后回读，再保存下一 checkpoint。status 写入失败时，
|
||||||
|
下次从外部事实识别完成结果；不能重发密码，也不能相信伪造的 Ready。
|
||||||
|
|
||||||
|
业务失败区分 InvalidSpec、ImmutableField、Conflict 等；依赖故障由适配器转换成
|
||||||
|
安全的能力失败，应用层决定重试并映射 Condition。凭据不进入模型序列化、status、
|
||||||
|
事件或错误明细；只能在实际需要它的执行边界短暂传递。
|
||||||
|
|
||||||
|
## 5. 用例走查与验收方向
|
||||||
|
|
||||||
|
| 场景 | 领域判定 | 应用与适配器执行／恢复 |
|
||||||
|
| --- | --- | --- |
|
||||||
|
| 登记 Instance | 当前配置的能力要求是否满足 | 读取管理凭据，验证连接与权限，准备并回读 registry；完成后才 Ready |
|
||||||
|
| 供应 Tenant | Instance 策略、绑定与归属允许供应 | 保存意图，认领资源，先写并回读 Bao 凭据，再创建 role/database，登录验证和 ESO 投射 |
|
||||||
|
| Bao 写入后进程中断 | 同一身份的部分状态可继续 | 回读原凭据继续，不生成第二份密码 |
|
||||||
|
| 两个 Tenant 竞争名称 | 只有匹配所有权的一方可继续 | 持久化认领和条件写入裁决竞争，失败方 Conflict，不覆盖资源 |
|
||||||
|
| Delete 中断 | 已消失资源可视为完成；剩余资源仍须归属正确 | 按规格顺序继续删除，全部回读不存在后才清 registry 和 finalizer |
|
||||||
|
| Retain 后同名 CR 重建 | 新 UID 不等于原所有者 | Conflict，不恢复管理、不改密码 |
|
||||||
|
|
||||||
|
领域测试验证规则与决策；adapter 测试验证锁、条件写入、SQL 与协议行为；controller
|
||||||
|
测试验证 checkpoint 持久化和重启恢复；E2E 验证最终合同。不能只验证一串 mock 调用
|
||||||
|
就声称实现了最终一致性。
|
||||||
|
|
||||||
|
## 6. 决策记录与待细化边界
|
||||||
|
|
||||||
|
1. **Instance 身份与物理目标（已确认）**：以管理员声明为准，endpoint 变更不验证
|
||||||
|
物理服务器／registry 连续性，不增加安装身份绑定检查；旧观察失效，重验新配置
|
||||||
|
的连接与管理能力。新 CR 视为新 Instance，不自动接管旧 UID 资源或迁移数据。
|
||||||
|
2. **Retain 完成条件**：外部依赖不可用不能永久阻止 CR 删除，但 registry 又需标记
|
||||||
|
unmanaged。需定义 CR 消失后的补偿／清扫入口及所需身份依据，不能承诺同时原子
|
||||||
|
完成两者，也不能在没有回读时声称已写入保留标记。
|
||||||
|
3. **管理凭据来源与 Ready（已确认）**：Instance 引用 controller namespace 内的
|
||||||
|
管理 Secret 名称和字段；管理员维护 ExternalSecret，ESO 同步。controller 不直接
|
||||||
|
从 Bao 读取管理凭据。已有凭据仍可访问 PG 时，Bao／ESO 故障不撤销 Instance Ready；
|
||||||
|
首次装配无有效 Secret 则失败。Secret 的有效用户名／密码变化时重建管理连接池并
|
||||||
|
重验，不因无关字段变化重建；controller 不修改 PG 密码，不回写 Secret 或 Bao。
|
||||||
|
4. **绑定时机**：系统规格写“首次成功后不可变”，API 文档写“首次创建外部状态后
|
||||||
|
不可变”。应明确绑定在认领、首次外部写入还是 Ready 时固定，及如何在 status 丢失
|
||||||
|
后恢复；否则供应中途改名称可能产生无人管理的资源。
|
||||||
|
|
||||||
|
5. **Instance 删除（已确认）**：开始受管即添加 finalizer；删除期间停止新供应，
|
||||||
|
有 Tenant 引用就等待，无引用才解除，不级联删除外部资源。首版采用 finalizer
|
||||||
|
与引用检查，不引入跨对象锁／准入控制；不保证并发创建与删除的原子性。
|
||||||
|
|
||||||
|
Tenant 的 Retain 等待决行为留到 Tenant 设计，不属于本轮 Instance 设计范围。
|
||||||
|
相关用例在决策批准前不进入实现，不同时实现整套模型。

|
|

|
| 项目 | 内容 |
|
||||||
|
| --- | --- |
|
||||||
|
| 状态 | Review；尚未在临时 PostgreSQL 演练 |
|
||||||
|
| 适用范围 | 任意既有数据库迁移为新建 v1alpha1 Tenant |
|
||||||
|
| 最后更新 | 2026-09-10 |
|
||||||
|
|
||||||
|
v1alpha1 不接管现有 database、role 或 OpenBao record。本流程通过逻辑 dump/restore 把
|
||||||
|
数据迁移到 controller 创建的新资源，保留旧资源作为限时回滚点。
|
||||||
|
|
||||||
|
以下命令是顺序模板，不可原样复制到真实环境。先把尖括号变量解析成明确值，确认当前
|
||||||
|
连接目标，再逐条执行。dump 可能包含敏感业务数据，必须放在加密临时存储且不得提交 Git。
|
||||||
|
|
||||||
|
## 前置条件
|
||||||
|
|
||||||
|
- 已验证 PostgreSQL/OpenBao 备份和恢复；记录恢复点。
|
||||||
|
- Instance 已 Ready，目标 namespace 存在，ESO ClusterSecretStore Ready。
|
||||||
|
- 最终 database/login role 当前由旧应用占用，但改名后的保留名称、新推导的 Bao path
|
||||||
|
均不存在。
|
||||||
|
- 已记录旧 database owner、grants、extensions、locale/encoding、连接配置和验证清单。
|
||||||
|
- 已确认应用可停止写入，并确定回滚窗口和负责人。
|
||||||
|
- 已确认旧 login role 不被其他 database/应用共享，且角色改名不会破坏未纳入本次维护
|
||||||
|
的依赖。
|
||||||
|
|
||||||
|
## 迁移顺序
|
||||||
|
|
||||||
|
### 1. 盘点与预演
|
||||||
|
|
||||||
|
```sh
|
||||||
|
pg_dump --schema-only --no-owner --no-privileges \
|
||||||
|
--dbname='<old-admin-connection>' > schema-preview.sql
|
||||||
|
```
|
||||||
|
|
||||||
|
检查不受 v1alpha1 管理的对象：额外 roles、跨库依赖、FDW、large objects、订阅、显式
|
||||||
|
tablespace、owner/grant 和目标实例不支持的 extension。无法映射为单 database + 单 login
|
||||||
|
owner 的环境必须先人工简化，不能让 controller 猜测。
|
||||||
|
|
||||||
|
### 2. 创建一致性 dump
|
||||||
|
|
||||||
|
停止应用写入并确认活跃写事务结束，然后创建最终 custom-format dump：
|
||||||
|
|
||||||
|
```sh
|
||||||
|
pg_dump --format=custom --no-owner --no-privileges \
|
||||||
|
--file='<secure-temp>/tenant.dump' \
|
||||||
|
--dbname='<old-admin-connection>'
|
||||||
|
pg_restore --list '<secure-temp>/tenant.dump'
|
||||||
|
```
|
||||||
|
|
||||||
|
不要删除旧 database/role。记录停写时间、dump checksum 和 PostgreSQL 版本。
|
||||||
|
|
||||||
|
### 3. 释放最终名称
|
||||||
|
|
||||||
|
保持应用停写，终止旧 database 的应用连接。连接其他管理 database，以管理员身份把旧
|
||||||
|
database 和旧 login role 改为明确的保留名称：
|
||||||
|
|
||||||
|
```sql
|
||||||
|
ALTER DATABASE <old_database> RENAME TO <old_database>_retained_<timestamp>;
|
||||||
|
ALTER ROLE <old_login_role> RENAME TO <old_login_role>_retained_<timestamp>;
|
||||||
|
```
|
||||||
|
|
||||||
|
identifier 必须由管理员工具安全引用，不能把未经校验的值直接拼入 SQL。PostgreSQL 在
|
||||||
|
角色改名时会清除以旧角色名加盐的 MD5 密码；使用 MD5 的旧环境必须在维护前准备安全的
|
||||||
|
密码重设/回滚方法。SCRAM verifier 不受角色名改动影响，但仍须实际验证回滚登录。
|
||||||
|
|
||||||
|
### 4. 创建受管空目标
|
||||||
|
|
||||||
|
应用 `PostgreSQLTenant`，使用未被占用的 database/loginRole，等待 Ready。确认：
|
||||||
|
|
||||||
|
- registry 记录 UID 正确；
|
||||||
|
- OpenBao metadata 属于该 Tenant；
|
||||||
|
- ExternalSecret Ready 且目标 Secret 已投射；
|
||||||
|
- 新凭据可以通过 DNS host 和 IP hostaddr 分别登录空 database。
|
||||||
|
|
||||||
|
### 5. Restore
|
||||||
|
|
||||||
|
从 OpenBao 或目标 Secret 安全取得新应用凭据，不要把密码放进 shell history。以新 login
|
||||||
|
owner 连接目标 database：
|
||||||
|
|
||||||
|
```sh
|
||||||
|
pg_restore --exit-on-error --no-owner --no-privileges \
|
||||||
|
--dbname='<new-application-connection>' \
|
||||||
|
'<secure-temp>/tenant.dump'
|
||||||
|
```
|
||||||
|
|
||||||
|
extension 应由 Tenant spec 创建。若 dump 仍包含 extension 定义，预演必须确认 restore
|
||||||
|
行为幂等；目标实例不支持的 extension 必须在迁移前解决。
|
||||||
|
|
||||||
|
### 6. 验证并切换
|
||||||
|
|
||||||
|
- 对比关键 schema、表数、行数/校验和、sequence、function 和 migration version。
|
||||||
|
- 用新 login 验证读写、migration 和应用健康检查。
|
||||||
|
- 将应用配置切换到新 Secret 或 OpenBao URL，保持旧数据库只读/停写。
|
||||||
|
- 观察一个约定窗口，确认错误率、连接数和关键业务功能。
|
||||||
|
|
||||||
|
### 7. 收尾
|
||||||
|
|
||||||
|
回滚窗口结束后，按独立变更删除旧 database/role/旧凭据；它们不属于 controller，禁止
|
||||||
|
通过 Tenant `Delete` 清理。安全删除 dump 和临时凭据材料，并记录验证结果。
|
||||||
|
|
||||||
|
## 回滚
|
||||||
|
|
||||||
|
在新目标出现问题且旧资源仍保留时：
|
||||||
|
|
||||||
|
1. 立即停止新目标写入。
|
||||||
|
2. 评估切换后是否产生新数据；若有，先决定反向迁移或接受丢弃，不能盲目切回。
|
||||||
|
3. 将应用连接切回 retained database/role；若必须恢复原名称，先确保新受管目标已用
|
||||||
|
`Delete` 完整清理或改用不同名称，再安全地反向执行 rename。
|
||||||
|
4. 恢复旧凭据（MD5 环境可能需要重设），验证旧服务。
|
||||||
|
5. 保留失败 Tenant 供排障；选择 Retain 或 Delete 前明确其外部资源后果。
|
||||||
|
|
||||||
|
若已经删除旧资源，则只能使用已验证备份恢复，不再属于本 runbook 的快速回滚。
|
||||||
|

||||||

||||||
|
| --- | --- |
|
||||||
|
| 状态 | Review；命令待实现后演练 |
|
||||||
|
| 最后更新 | 2026-09-10 |
|
||||||
|
|
||||||
|
## 日常检查
|
||||||
|
|
||||||
|
先看 API 合同，而不是从日志猜状态：
|
||||||
|
|
||||||
|
```sh
|
||||||
|
kubectl get postgresqlinstances
|
||||||
|
kubectl get postgresqltenants -A
|
||||||
|
kubectl get postgresqltenant -n <namespace> <name> -o yaml
|
||||||
|
kubectl describe postgresqltenant -n <namespace> <name>
|
||||||
|
```
|
||||||
|
|
||||||
|
随后检查 controller 日志、ExternalSecret/Secret、OpenBao metadata、registry 和
|
||||||
|
PostgreSQL catalog。排障时不得把 Secret data 或带 Token 的请求粘贴到 issue/日志。
|
||||||
|
`status.phase` 是 controller 状态机 checkpoint，也用于定位当前步骤；`Ready`
|
||||||
|
Condition/Reason 用于判断对外结果。phase 不能替代外部事实，清空或不一致时应由
|
||||||
|
controller 自动重建/纠正。
|
||||||
|
|
||||||
|
## 常见 Reason
|
||||||
|
|
||||||
|
| Reason | 首要检查 |
|
||||||
|
| --- | --- |
|
||||||
|
| `InvalidSpec` / `ImmutableField` | API 字段、identifier、不可变/只追加约束 |
|
||||||
|
| `DependencyUnavailable` | 网络、DNS、服务状态和超时 |
|
||||||
|
| `AuthenticationFailed` | 管理凭据、CA、DNS/IP SAN、OpenBao auth |
|
||||||
|
| `InsufficientPrivileges` | PostgreSQL grants、OpenBao policy、Kubernetes RBAC |
|
||||||
|
| `InstanceNotReady` | 先恢复所引用 Instance |
|
||||||
|
| `Conflict` | registry UID、同名 DB/role、OpenBao metadata；禁止直接覆盖 |
|
||||||
|
| `CredentialProjectionFailed` | ClusterSecretStore、ExternalSecret Condition、目标 Secret |
|
||||||
|
| `ProvisioningFailed` | `status.phase` 及对应外部资源的回读结果 |
|
||||||
|
|
||||||
|
修复依赖后让正常 reconcile 自动重试。不要通过删除/重建 CR 规避 Conflict；新 UID 只会
|
||||||
|
使已有保留资源继续冲突。
|
||||||
|
|
||||||
|
## Retain 后的资源
|
||||||
|
|
||||||
|
Retain 删除完成后，database、role、OpenBao record 和 registry 所有权记录仍存在但标记
|
||||||
|
unmanaged。v1alpha1 不支持重新关联。需要恢复管理时，使用 [`migration.md`](migration.md)
|
||||||
|
把数据迁移到一个全新受管名称；不要手工把 registry UID 改成新 CR UID。
|
||||||
|
|
||||||
|
## Delete 卡住
|
||||||
|
|
||||||
|
1. 暂停应用写入并记录 Tenant UID、Instance UID、database、role 和 Bao path。
|
||||||
|
2. 从 registry 和 OpenBao metadata 独立确认所有权。
|
||||||
|
3. 检查删除阶段，修复 PostgreSQL/OpenBao/ESO 依赖，让 controller 继续。
|
||||||
|
4. 若依赖永久丢失，列出每个可能残留的 database、role、KV metadata 和 Secret。
|
||||||
|
5. 只有确认接受这些残留后，才人工移除 finalizer。
|
||||||
|
|
||||||
|
最终 finalizer 名称由 API 实现固定后补入命令。人工移除 finalizer不会执行剩余清理，
|
||||||
|
也不会把外部资源变成可由新 CR 接管的资源。
|
||||||
|
|
||||||
|
## 备份与恢复
|
||||||
|
|
||||||
|
- PostgreSQL VM/磁盘备份必须与数据库一致性策略配套；仅复制在线磁盘不自动等于有效
|
||||||
|
PostgreSQL 备份。
|
||||||
|
- PostgreSQL 备份必须包含管理 database 中的 controller registry。
|
||||||
|
- OpenBao 使用独立的受支持备份/快照流程，且恢复点应与 PostgreSQL 尽量接近。
|
||||||
|
- Kubernetes 侧备份 CR、controller 配置、ClusterSecretStore 和公开 CA bundle，不备份
|
||||||
|
明文 Secret 作为凭据事实来源。
|
||||||
|
- 定期在隔离环境执行恢复演练，验证 registry、KV metadata、应用登录及 Retain/Delete。
|
||||||
|
|
||||||
|
恢复后先停止 controller，核对 PostgreSQL/OpenBao 时间点与 UID 映射，再启动单副本
|
||||||
|
controller 观察；出现一侧存在、一侧缺失时不得手工生成新密码或改 registry，应先按
|
||||||
|
Conflict 处理并决定恢复哪一侧。
|
||||||
|
|
||||||
|
## 升级与紧急停止
|
||||||
|
|
||||||
|
有疑似越权删除或凭据泄漏时，先把 controller Deployment scale 到 0，保留 CR、registry
|
||||||
|
和日志证据，再撤销 OpenBao token/role 并限制 PostgreSQL 管理 role。恢复前在隔离环境
|
||||||
|
复现并确认不会扩大破坏。一般依赖故障无需 scale down，最终一致性会自动重试。

|
||||||
|
| 状态 | Review |
|
||||||
|
| 最后更新 | 2026-09-10 |
|
||||||
|
|
||||||
|
## 保护目标
|
||||||
|
|
||||||
|
- 应用密码只存在于 OpenBao、ESO 投射的目标 Secret 和需要使用它的进程内存中。
|
||||||
|
- controller 只能修改其 registry 能证明归属当前 Tenant UID 的资源。
|
||||||
|
- namespace 租户不能越权管理 Instance、其他 namespace 或 controller 配置。
|
||||||
|
- PostgreSQL 和 OpenBao 的网络身份使用受信 CA 验证，不因 DNS 不可用而降级 TLS。
|
||||||
|
|
||||||
|
## 信任边界
|
||||||
|
|
||||||
|
Kubernetes 管理员、OpenBao 管理员和 PostgreSQL 管理员是平台信任主体。能读取 Tenant
|
||||||
|
目标 Secret 或对应 OpenBao path 的主体等同于持有数据库账号。database owner 可以
|
||||||
|
改变自己 database 内的对象，因此 COMMENT 不能作为 controller 所有权依据。
|
||||||
|
|
||||||
|
VM/磁盘备份会包含 PostgreSQL registry 和租户数据，但不应包含 OpenBao 中的密码；完整
|
||||||
|
灾难恢复必须同时保护 PostgreSQL 与 OpenBao，并控制两份备份的访问权限。
|
||||||
|
|
||||||
|
## 凭据处理
|
||||||
|
|
||||||
|
- controller 使用 Kubernetes auth 获取短期 OpenBao token，不配置长期静态 token。
|
||||||
|
- 管理凭据只从 Instance 引用的 controller namespace Secret 读取，不复制到
|
||||||
|
CR/status/Event/metric/trace；管理员维护 ExternalSecret，由 ESO 同步该 Secret。
|
||||||
|
- 租户密码使用密码学安全随机源生成一次；中断恢复必须复用 OpenBao 现值。
|
||||||
|
- controller 创建 ExternalSecret，不直接创建含 data/stringData 的 Secret。
|
||||||
|
- 日志字段允许 namespace/name、UID、generation、阶段和错误类别；禁止记录请求/响应体、
|
||||||
|
DSN、Authorization header、密码或完整 OpenBao URL path 作为 metric label。
|
||||||
|
- panic、错误包装和测试失败输出必须经过凭据泄漏测试。
|
||||||
|
|
||||||
|
## TLS
|
||||||
|
|
||||||
|
- homelab 默认 `verify-full`，`disable` 只允许显式开发配置。
|
||||||
|
- server 证书同时覆盖 DNS `host` 和 IP `hostaddr`；消费者自行选择连接目标。
|
||||||
|
- OpenBao PKI 保管 CA 私钥并负责签发/续期。controller Deployment 只挂载公开 CA
|
||||||
|
bundle，挂载只读且使用最小文件权限。
|
||||||
|
- 证书轮换必须先发布同时信任新旧 CA 的 bundle，再轮换服务端证书，最后移除旧 CA。
|
||||||
|
|
||||||
|
## 最小权限
|
||||||
|
|
||||||
|
OpenBao controller identity 只管理固定 tenant base path，不读取管理凭据。管理凭据
|
||||||
|
ESO 身份只读管理路径，租户 ESO 身份只读 tenant base path，二者隔离，Tenant 不得
|
||||||
|
使用管理凭据 Store。controller 对管理 Secret 的读取限于自身 namespace，Instance
|
||||||
|
不能指定其他 namespace；controller 不创建或修改管理 Secret／ExternalSecret。
|
||||||
|
|
||||||
|
PostgreSQL 管理 role 不应是 superuser。若平台选择 SECURITY DEFINER 函数承载创建或
|
||||||
|
删除操作，函数必须固定 `search_path`、严格校验 identifier、拒绝任意 SQL，并仅向
|
||||||
|
controller role 授予 EXECUTE。controller 不调用 shell 或 `psql` 拼接用户输入。
|
||||||
|
|
||||||
|
Kubernetes RBAC 应把 cluster-scoped Instance 管理限制给平台管理员。Tenant editor
|
||||||
|
不自动获得 Secret read；是否读取目标 Secret 由 namespace 内独立 RBAC 决定。
|
||||||
|
|
||||||
|
## 删除保护
|
||||||
|
|
||||||
|
Delete 是明确的数据销毁授权，但仍必须在每一步校验 Instance UID、Tenant UID、名称和
|
||||||
|
OpenBao metadata。禁止对未知对象使用 `CASCADE`。删除 finalizer 卡住时只能按
|
||||||
|
[`operations.md`](operations.md) 核实外部状态后人工移除；该操作可能遗留资源。
|
||||||
|
|
||||||
|
## 发布前安全验收
|
||||||
|
|
||||||
|
- 使用错误 CA、错误 DNS 名和错误 IP 时连接失败；正确 DNS/IP SAN 均成功。
|
||||||
|
- namespace 用户不能修改 Instance 或跨 namespace Tenant/ExternalSecret。
|
||||||
|
- controller/ESO 的 OpenBao policy 互相隔离，越权请求被拒绝。
|
||||||
|
- 应用 login 不能创建 role/database，也不能连接其他租户 database。
|
||||||
|
- 日志、Event、Condition、metrics、CR 导出和测试 artifact 不含 canary password/token。
|
||||||
|
- 伪造 COMMENT、同名 database/role 或错误 UID metadata 均不能绕过 Conflict。
|
||||||
|
- Delete 只销毁 registry 可证明归属当前 Tenant 的资源。

|
|
||||||
|
本文档定义系统对用户和外部依赖呈现的行为，是 API、测试和实现共同遵守的合同。
|
||||||
|
实现若需要改变本文合同，必须先修改规格并重新获得批准。
|
||||||
|
|
||||||
|
文中的“必须”“禁止”“应当”“可以”分别对应强制要求、强制限制、推荐行为和可选
|
||||||
|
行为。
|
||||||
|
|
||||||
|
## 1. 背景
|
||||||
|
|
||||||
|
homelab 中的大部分应用共享一个运行在独立 VM 上的 PostgreSQL DBMS。应用需要各自
|
||||||
|
独立的 database、作为 owner 的 login role 和密码，但不需要独立 PostgreSQL 实例。
|
||||||
|
目前这些资源依靠人工 SQL 和人工 Secret 管理，难以重复、审计和检测漂移。
|
||||||
|
|
||||||
|
本系统使用 Kubernetes CRD 作为声明式 API，持续协调外部 PostgreSQL 与 OpenBao：
|
||||||
|
|
||||||
|
```text
|
||||||
|
PostgreSQLInstance / PostgreSQLTenant
|
||||||
|
|
|
||||||
|
v
|
||||||
|
Ayatori Database controller
|
||||||
|
| |
|
||||||
|
v v
|
||||||
|
PostgreSQL catalog OpenBao KV v2
|
||||||
|
```
|
||||||
|
|
||||||
|
## 2. 目标
|
||||||
|
|
||||||
|
v1alpha1 必须实现以下目标：
|
||||||
|
|
||||||
|
1. 注册一个已经存在的外部 PostgreSQL 实例并报告连接状态。
|
||||||
|
2. 为一个应用租户创建独立 database 和一个同时作为 database owner 的 login role。
|
||||||
|
3. 根据实例实际可安装扩展列表检查并安装租户申请的 PostgreSQL extension。
|
||||||
|
4. 首次生成高强度长期密码，并只把凭据明文写入 OpenBao KV v2。
|
||||||
|
5. 为 Kubernetes 应用创建 ExternalSecret，由 ESO 将凭据投射到同 namespace Secret。
|
||||||
|
6. 同时输出 OpenBao API URL，使 Kubernetes 外的应用可以直接读取凭据。
|
||||||
|
7. 同时输出 PostgreSQL DNS hostname 和 IP address，不假定所有消费者都能使用集群内
|
||||||
|
DNS。
|
||||||
|
8. 持续检测并修正由本系统管理的非破坏性漂移。
|
||||||
|
9. 通过 Kubernetes Condition 报告进度、成功和可操作的失败原因。
|
||||||
|
10. 重复 reconcile、controller 重启及外部依赖暂时失败不得重复创建或破坏资源。
|
||||||
|
11. 删除 Tenant CR 时默认保留外部资源；显式选择 `Delete` 时提供完整清理路径。
|
||||||
|
|
||||||
|
## 3. 非目标
|
||||||
|
|
||||||
|
v1alpha1 不负责：
|
||||||
|
|
||||||
|
- 创建、升级、备份或高可用运行 PostgreSQL DBMS/VM；
|
||||||
|
- 创建或运维 OpenBao；
|
||||||
|
- 直接写入包含凭据明文的 Kubernetes Secret；Secret 必须由 ESO 投射；
|
||||||
|
- 动态凭据、定时或自动密码轮换；
|
||||||
|
- Web UI、独立 REST API 或 Backstage 插件；
|
||||||
|
- 跨实例迁移 database；
|
||||||
|
- schema/table 级别租户、多 login role 或跨租户 grant；
|
||||||
|
- 删除不属于本系统管理的 database、role、extension 或 OpenBao Secret；
|
||||||
|
- 接管不是由本系统创建的外部资源；
|
||||||
|
- 提供生产环境 SLA。

||||||
|
PostgreSQL 管理 role。应用或 GitOps 流程在获得 namespace RBAC 后管理
|
||||||
|
`PostgreSQLTenant`。
|
||||||
|
|
||||||
|
## 5. 资源模型
|
||||||
|
|
||||||
|
### 5.1 PostgreSQLInstance
|
||||||
|
|
||||||
|
`PostgreSQLInstance` 是 cluster-scoped 资源，表示一个已经存在、可由 controller
|
||||||
|
管理的 PostgreSQL server。
|
||||||
|
|
||||||
|
它必须声明：
|
||||||
|
|
||||||
|
- PostgreSQL host、port 和管理连接使用的 database；
|
||||||
|
- PostgreSQL host address，供无法解析 DNS 的消费者使用；
|
||||||
|
- TLS mode；
|
||||||
|
- controller namespace 中 PostgreSQL 管理 Secret 的名称和字段名。
|
||||||
|
|
||||||
|
可安装的 extension 集合由应用层从目标 PostgreSQL 查询，不由管理员在 Instance
|
||||||
|
中声明。v1alpha1 不实现 allowlist；该概念保留为后续可选策略。实际可用不代表安装
|
||||||
|
权限及前置条件已满足，安装仍需执行并回读；查询失败不得被解释为扩展不支持。
|
||||||
|
|
||||||
|
实例 Ready 不代表 PostgreSQL 数据有备份或高可用，只表示 controller 当前可以安全
|
||||||
|
建立管理连接、读取 server metadata、访问 controller registry 并使用所需管理能力。
|
||||||
|
|
||||||
|
Instance 身份和 endpoint 以管理员声明为准。修改 endpoint 不验证是否仍是原物理
|
||||||
|
服务器或原 registry，不增加服务器／安装身份绑定检查；但旧配置观察失效，必须按
|
||||||
|
新配置重新检查连接和管理能力。新 CR 按新 Instance 处理，不自动接管旧 UID 的租户
|
||||||
|
资源。controller 不迁移旧服务器上的数据，也不清理旧目标，影响由管理员负责评估。
|
||||||
|
|
||||||
|
Instance 开始受管时即添加 finalizer，成功保存后才参与供应，不等发现 Tenant 后
|
||||||
|
再补加。删除期间停止新供应；仍有引用它的 Tenant（包括正在删除的 Tenant）时保留
|
||||||
|
finalizer，无引用后才移除。不级联删除 Tenant 或任何外部数据库、角色、凭据。
|
||||||
|
引用检查失败不得当作无引用。首版不引入跨对象锁或准入控制：finalizer 不禁止同时
|
||||||
|
创建 Tenant CR，新 Tenant 遇到正在删除或已不存在的 Instance 时不得开始供应。
|
||||||
|
这不保证列表检查、CR 创建和在途外部操作之间的原子性；不是严格的跨对象事务。
|
||||||
|
|
||||||
|
### 5.2 PostgreSQLTenant
|
||||||
|
|
||||||
|
`PostgreSQLTenant` 是 namespaced 资源。v1alpha1 中，一个 Tenant 精确对应：
|
||||||
|
|
||||||
|
- 一个 `PostgreSQLInstance`；
|
||||||
|
- 一个 database；
|
||||||
|
- 一个同时作为 database owner、供应用使用的 `LOGIN` role；
|
||||||
|
- 零个或多个 extension；
|
||||||
|
- 一个 OpenBao KV v2 凭据位置；
|
||||||
|
- 一个同 namespace ExternalSecret 及其目标 Kubernetes Secret。
|
||||||
|
|
||||||
|
Tenant 的 namespace 用于 Kubernetes RBAC 和身份识别，不代表 PostgreSQL schema。
|
||||||
|
同一 Instance 中的 database 和 role 名称全局唯一。
|
||||||
|
|
||||||
|
## 6. 标识与默认值
|
||||||
|
|
||||||
|
以下是 v1alpha1 的标识合同：
|
||||||
|
|
||||||
|
| 字段 | 默认值 | 约束 |

||||||

| --- | --- | --- |
|
||||||
|
| Instance port | `5432` | 1–65535 |
|
||||||
|
| Instance host address | 无 | 必须是合法 IPv4 或 IPv6 address |
|
||||||
|
| 管理 database | `postgres` | 合法 PostgreSQL identifier |
|
||||||
|
| TLS mode | `verify-full` | 禁止隐式降级 |
|
||||||
|
| Tenant database | `metadata.name` | 同一 Instance 全局唯一 |
|
||||||
|
| login role | `metadata.name` | 同一 Instance 全局唯一 |
|

|
||||||
|
|
||||||
|
Tenant 的 `spec.instanceRef` 与 `metadata.name` 长度合计不得超过 241 个字符，确保
|
||||||
|
派生的 ExternalSecret/Secret 默认名称
|
||||||
|
`<instanceRef>-<metadata.name>-postgresql` 不超过 Kubernetes 253 字符限制。
|
||||||
|
|
||||||
|
固定默认值由 CRD defaulting 写入。依赖 `metadata.name` 或 `instanceRef` 的 database、
|
||||||
|
login role、ExternalSecret/Secret 名称属于 controller 语义默认值：省略字段不会被 admission
|
||||||
|
回写，controller 必须始终计算同一个 effective value，并通过 status 的 database、
|
||||||
|
loginRole、credential reference 以及实际资源展示。
|
||||||
|
v1alpha1 不为此引入 mutating webhook。
|
||||||
|
|
||||||
|
database 和 role 名称必须作为 PostgreSQL identifier 参数安全引用，禁止通过字符串
|
||||||
|
拼接执行。名称校验必须拒绝空字符串、NUL 和超过 PostgreSQL identifier 长度限制的
|
||||||
|
值，并统一限制为小写字母、数字和下划线。
|
||||||
|
|
||||||
|
Tenant 首次成功后，`instanceRef`、database、login role 和凭据位置必须
|
||||||
|
不可变。修改这些字段不是 rename 或 migration，API 必须拒绝或报告明确的
|
||||||
|
`ImmutableField`。
|
||||||
|
|
||||||
|
## 7. PostgreSQL 权限合同
|
||||||
|
|
||||||
|
建议的 v1alpha1 权限模型如下：
|
||||||
|
|
||||||
|
1. database 必须由 login role 拥有。
|
||||||
|
2. login role 必须是 `LOGIN NOSUPERUSER NOCREATEDB NOCREATEROLE NOREPLICATION`。
|
||||||
|
3. 必须撤销 `PUBLIC` 对租户 database 的连接权限，再显式允许 login role 连接。
|
||||||
|
4. controller 不得修改其他 database 或无关 role 的权限。
|
||||||
|
5. controller 只保证请求的 extension 存在；移除 extension 不得自动执行
|
||||||
|
`DROP EXTENSION`。
|
||||||
|
|
||||||
|
这意味着应用可以在自己的 database 内执行 schema migration，但不能创建其他
|
||||||
|
database、role 或访问其他租户。v1alpha1 不创建只有形式意义、却未隔离运行时权限的
|
||||||
|
额外 `NOLOGIN` owner。若以后应用能分别使用 migration 和 runtime 凭据，再通过新的
|
||||||
|
权限 profile 引入 owner/migrator/runtime 角色模型。
|
||||||
|
|
||||||
|
## 8. OpenBao 凭据合同
|
||||||
|
|
||||||
|
### 8.1 Controller 自身认证
|
||||||
|
|
||||||
|
controller 必须使用 Kubernetes auth 登录 OpenBao。controller 使用的 OpenBao API
|
||||||
|
address、提供给消费者的 OpenBao API address、auth mount、auth role 和 KV v2 mount
|
||||||
|
属于部署配置，不属于任何 CR。两个 API address 可以相同；若 controller 使用集群内
|
||||||
|
地址而外部消费者不能解析，则必须单独配置 consumer address。生产部署的 KV mount
|
||||||
|
默认为 `kv`；开发环境可以配置为 OpenBao dev server 默认的 `secret`。长期 OpenBao
|
||||||
|
Token 禁止写入 Deployment、CR 或镜像。
|
||||||
|
|
||||||
|
### 8.2 管理凭据
|
||||||
|
|
||||||
|
`PostgreSQLInstance` 只引用 controller 自身 namespace 中 Kubernetes Secret 的名称及
|
||||||
|
用户名、密码字段名，不允许指定 namespace 或 Bao path。endpoint 仍由 Instance 声明。
|
||||||
|
平台管理员维护 ExternalSecret，将 OpenBao 管理凭据同步到该 Secret；controller 只读
|
||||||
|
Secret，不创建或修改管理 Secret、其 ExternalSecret 或上游管理凭据。
|
||||||
|
|
||||||
|
Instance 管理连接不直接访问 Bao，不负责管理密码轮换。已装配的凭据仍可访问
|
||||||
|
PostgreSQL 且满足 registry／权限要求时，Bao 或 ESO 暂时不可用不使 Instance NotReady。
|
||||||
|
首次装配无法取得有效 Secret 时不能 Ready。检测到所引用 Secret 的有效用户名或密码
|
||||||
|
变化时，controller 使用新值重建管理连接池并重新检查管理能力；仅 metadata 或无关
|
||||||
|
字段变化不触发重建。刷新不依赖 Instance generation 变化，新连接验证失败按实际
|
||||||
|
故障报告，不能用旧连接的成功结果证明新凭据可用。
|
||||||
|
controller 不修改 PostgreSQL 密码、不回写 Secret，也不修改 Bao 管理凭据；数据库侧
|
||||||
|
凭据变更由管理员负责。这是跟随已提供凭据的连接刷新，不是自动密码轮换。
|
||||||
|
Tenant 凭据管理仍直接依赖 Bao。
|
||||||
|
|
||||||
|
### 8.3 租户凭据
|
||||||
|
|
||||||
|
Tenant 不声明凭据 path。controller 根据部署级 KV mount、base path 和 Tenant 的
|
||||||
|
namespace/name 推导唯一的 mount-relative path。base path 来自 controller 启动参数
|
||||||
|
`--openbao-tenant-base-path`，默认 `postgresql-tenants`。最终路径为
|
||||||
|
`<base-path>/<namespace>/<metadata.name>`。推导结果禁止以 `/` 开头，禁止包含空路径段、
|
||||||
|
`.`、`..`，也禁止把 KV v2 HTTP API 的 `data` 或 `metadata` 层编码进路径。
|
||||||
|
|
||||||
|
新 Tenant 的凭据建立顺序必须可从任意中断点恢复：
|
||||||
|
|
||||||
|
1. 验证 Instance、名称、extension 和目标 OpenBao 路径；
|
||||||
|
2. 确认目标 database、role 和 OpenBao 记录不存在，或能够验证为同一 Tenant
|
||||||
|
已创建的部分状态；
|
||||||
|
3. 生成密码；
|
||||||
|
4. 先创建带 controller 所有权 metadata 的 OpenBao KV v2 记录；
|
||||||
|
5. 从 OpenBao 重新读取凭据；
|
||||||
|
6. 使用该凭据创建作为 database owner 的 login role 和其他 PostgreSQL 资源；
|
||||||
|
7. 用 login role 实际连接目标 database；
|
||||||
|
8. 全部验证成功后将 Tenant 标记 Ready。
|
||||||
|
|
||||||
|
若第 4 步成功、后续 PostgreSQL 操作失败，下一轮必须读取同一份 OpenBao 凭据继续，
|
||||||
|
不得生成第二个密码。若 PostgreSQL 先存在而 OpenBao 记录不存在，controller 必须报告
|
||||||
|
Conflict，不得擅自重置已有 role 密码。
|
||||||
|
|
||||||
|
controller 必须在 PostgreSQL 管理 database 的专用 registry schema 中持久保存可验证的
|
||||||
|
Instance UID、Tenant UID 与 namespace/name 关联，不能只依赖会丢失的 CR status 判断
|
||||||
|
资源所有权。registry 必须可回读且不得改变数据库授权语义；database 或 role COMMENT
|
||||||
|
不能作为权威所有权记录。
|
||||||
|
|
||||||
|
默认写入字段固定为：
|
||||||
|
|
||||||
|
```text
|
||||||
|
username
|
||||||
|
password
|
||||||
|
database
|
||||||
|
host
|
||||||
|
hostaddr
|
||||||
|
port
|
||||||
|
sslmode
|
||||||
|
```
|
||||||
|
|
||||||
|
这些字段是 controller 的规范化输出合同。controller 不生成包含密码的 URI、JDBC URL
|
||||||
|
或应用专用键名。应用通过 ExternalSecret template、Helm values 或自身配置把原子字段
|
||||||
|
映射为 `DATABASE_URL`、独立环境变量或配置文件；因此 URI escaping 和应用特有格式也
|
||||||
|
由消费方负责。`host` 是 DNS 名称，`hostaddr` 是可直接连接的 IP；消费者自行选择其
|
||||||
|
支持且可达的连接目标。PostgreSQL server 证书必须同时包含与 `host` 匹配的 DNS SAN
|
||||||
|
和与 `hostaddr` 匹配的 IP SAN，使两种目标都能在 `verify-full` 下独立完成身份验证。
|
||||||
|
|
||||||
|
### 8.4 凭据输出与 ExternalSecret
|
||||||
|
|
||||||
|
controller 必须根据部署级 base path 推导 Tenant 的 KV path，Tenant 不能选择 mount 或
|
||||||
|
任意远端路径。ExternalSecret 固定命名为
|
||||||
|
`<instanceRef>-<metadata.name>-postgresql`。Tenant 可以通过
|
||||||
|
`spec.credential.secretName` 指定目标 Kubernetes Secret 名称；省略时使用同一默认名。
|
||||||
|
自定义名称只需是合法 Kubernetes Secret 名称，不限制命名内容；两者均与 Tenant 位于
|
||||||
|
同一 namespace。
|
||||||
|
|
||||||
|
controller 必须创建同 namespace ExternalSecret，从固定的 ClusterSecretStore 读取七个
|
||||||
|
原子字段。ExternalSecret 及目标 Secret 的名称通过 Tenant status 暴露。controller
|
||||||
|
不得直接读取 OpenBao 密码后写入 Kubernetes Secret。
|
||||||
|
|
||||||
|
Tenant status 还必须提供完整、可由外部消费者使用的 OpenBao KV v2 API URL。URL 可以
|
||||||
|
包含 consumer API address、mount 和 secret path，但不得包含 Token、密码或其他认证
|
||||||
|
信息。默认 `kubectl get` 表格显示目标 Secret 名称；完整 OpenBao URL 通过
|
||||||
|
`kubectl get postgresqltenant <name> -o yaml` 获取，避免表格列过长。
|
||||||
|
|
||||||
|
OpenBao metadata 必须能够标识 Tenant UID、namespace/name 和 Instance，使 controller
|
||||||
|
区分自己的残留记录与外部记录。任何凭据值都不得进入日志、Event、Condition、metric
|
||||||
|
label、trace、CR spec/status 或测试快照。
|
||||||
|
|
||||||
|
## 9. Reconcile 行为
|
||||||
|
|
||||||
|
系统采用最终一致性模型。Kubernetes、PostgreSQL、OpenBao 和 ESO 可以短暂处于不同
|
||||||
|
阶段；controller 不尝试实现跨系统事务，而是以 Kubernetes CR `status.phase` 作为
|
||||||
|
工作流 checkpoint，通过幂等外部操作和每轮回读验证最终收敛。
|
||||||
|
|
||||||
|
两个 CR 的状态机权威记录都在 `status.phase`。controller 根据 phase 选择下一项候选
|
||||||
|
动作，但 phase 不能替代外部状态检查：执行前后仍须回读 PostgreSQL catalog、registry、
|
||||||
|
OpenBao 和 Kubernetes/ESO。外部写入成功但 status 更新失败时，下一轮必须识别已完成
|
||||||
|
事实并推进 phase，不得重复生成密码或报告虚假冲突。
|
||||||
|
|
||||||
|
status 丢失时，controller 必须从 registry 的所有权记录和各外部系统实际状态保守重建
|
||||||
|
phase。若 status 被伪造或领先于实际状态，controller 必须纠正到安全阶段并补齐资源，
|
||||||
|
不能跳过验证。registry 不保存或驱动协调 phase。
|
||||||
|
|
||||||
|
Instance phase 按当前 generation 表示连接与初始化进度：
|
||||||
|
|
||||||
|
```text
|
||||||
|
Pending -> Validating -> InitializingRegistry -> Ready
|
||||||
|
(any phase) --------------------------------> Deleting
|
||||||
|
```
|
||||||
|
|
||||||
|
spec generation 改变后可以从 `Ready` 回到 `Validating`。Tenant phase 如下：
|
||||||
|
|
||||||
|
```text
|
||||||
|
Pending -> Planned -> CredentialCreated -> RoleCreated -> DatabaseCreated
|
||||||
|
-> ExternalSecretCreated -> CredentialProjected -> Ready -> Deleting
|
||||||
|
```
|
||||||
|
|
||||||
|
失败不增加 `Failed` phase；phase 保留在无法推进的步骤，由 `Ready=False` 的 Reason 和
|
||||||
|
message 表达 `Conflict`、认证失败或依赖不可用。Retain 删除完成后 CR 已不存在，因此
|
||||||
|
没有持久的 `Retained` phase。
|
||||||
|
|
||||||
|
每轮 Tenant reconcile 必须按以下逻辑执行：
|
||||||
|
|
||||||
|
```text
|
||||||
|
读取 Tenant
|
||||||
|
-> 读取 Instance
|
||||||
|
-> 校验不可变字段与输入
|
||||||
|
-> 检查 Instance Ready
|
||||||
|
-> 读取 OpenBao 与 PostgreSQL 实际状态
|
||||||
|
-> 检测冲突或部分完成状态
|
||||||
|
-> 执行非破坏性补齐
|
||||||
|
-> 使用应用凭据验证登录
|
||||||
|
-> 创建并验证 ExternalSecret/Secret 投射
|
||||||
|
-> 回读实际状态
|
||||||
|
-> 更新 status
|
||||||
|
```
|
||||||
|
|
||||||
|
要求：
|
||||||
|
|
||||||
|
- 所有步骤必须幂等；
|
||||||
|
- 每个外部写入前必须先在 CR status 持久化足够的操作意图，写入后必须回读并推进
|
||||||
|
`status.phase`；
|
||||||
|
- 暂时性网络、锁和依赖错误必须重试；
|
||||||
|
- 输入错误、资源冲突和禁止操作不得忙循环重试，只在 generation 或依赖状态变化后
|
||||||
|
重试；
|
||||||
|
- 未知外部资源不得被修改、接管或删除；
|
||||||
|
- 用户从 `spec.extensions` 移除 extension 时不得执行卸载，必须报告该字段在 v1alpha1
|
||||||
|
中只允许追加；
|
||||||
|
- controller 重启不得影响已经签发的应用密码；
|
||||||
|
- `status` 丢失后必须可以从 registry、PostgreSQL、OpenBao 和 Kubernetes/ESO 重建。
|
||||||
|
|
||||||
|
## 10. Condition 合同
|
||||||
|
|
||||||
|
两个资源都必须提供唯一的 `Ready` Condition。可以增加辅助 Condition，但调用方只需
|
||||||
|
依赖 `Ready`。
|
||||||
|
|
||||||
|
| 状态 | 含义 |
|
||||||
|
| --- | --- |
|
||||||
|
| `Ready=Unknown` | 正在首次观察或 reconcile，尚无结论 |
|
||||||
|
| `Ready=False` | 当前 generation 未达到合同要求 |
|
||||||
|
| `Ready=True` | 当前 generation 已回读验证成功 |
|
||||||
|
|
||||||
|
Condition 必须带正确的 `observedGeneration`。资源自身的
|
||||||
|
`status.observedGeneration` 只在当前 generation 完成一次有结论的 reconcile 后更新。
|
||||||
|
|
||||||
|
最低 Reason 集合：
|
||||||
|
|
||||||
|
| Reason | 适用资源 | 含义 |
|
||||||
|
| --- | --- | --- |
|
||||||
|
| `Reconciling` | 两者 | 尚在处理 |
|
||||||
|
| `Ready` | 两者 | 当前 generation 已验证 |
|
||||||
|
| `InvalidSpec` | 两者 | 输入不满足规格 |
|
||||||
|
| `DependencyUnavailable` | 两者 | PostgreSQL 或 OpenBao 暂时不可用 |
|
||||||
|
| `AuthenticationFailed` | Instance | 管理凭据或 TLS 验证失败 |
|
||||||
|
| `InsufficientPrivileges` | Instance | 管理 role 缺少必要权限 |
|
||||||
|
| `InstanceNotReady` | Tenant | 引用的 Instance 未 Ready |
|
||||||
|
| `Conflict` | Tenant | 目标名称或 OpenBao 路径已被其他主体占用 |
|
||||||
|
| `ProvisioningFailed` | Tenant | 可重试的创建/验证失败 |
|
||||||
|
| `CredentialProjectionFailed` | Tenant | ESO 或目标 Secret 未达到期望状态 |
|
||||||
|
|
||||||
|
Condition message 必须适合人类排障，但禁止包含连接串密码、Token 或完整 Secret 数据。
|
||||||
|
|
||||||
|
## 11. 删除与保留
|
||||||
|
|
||||||
|
### 11.1 Retain
|
||||||
|
|
||||||
|
`Retain` 是默认策略：
|
||||||
|
|
||||||
|
- 删除 Tenant CR 不得删除 database、role、extension 或 OpenBao 记录；
|
||||||
|
- controller 不得因外部依赖不可用而永久阻止 Retain CR 删除；
|
||||||
|
- 保留资源必须继续携带原 Tenant UID 和 namespace/name 的所有权记录，但在 CR 删除后
|
||||||
|
明确处于 unmanaged 状态；
|
||||||
|
- 重新创建同名 Tenant 会产生新的 UID，必须因已有资源不属于新 UID 而报告 Conflict；
|
||||||
|
- v1alpha1 不提供重新关联、import 或 adoption；恢复管理必须使用第 12 节的迁移流程，
|
||||||
|
或等待后续版本定义显式纳管协议。
|
||||||
|
|
||||||
|
### 11.2 Delete
|
||||||
|
|
||||||
|
用户在创建 Tenant 时显式设置 `deletionPolicy: Delete`，表示删除 CR 时授权永久清理
|
||||||
|
该 Tenant 的外部资源。controller 必须使用 finalizer，并按以下顺序处理：
|
||||||
|
|
||||||
|
1. 再次验证 database、role 和 OpenBao 记录都属于当前 Tenant UID；
|
||||||
|
2. 删除 ExternalSecret，并确认目标 Kubernetes Secret 已删除；
|
||||||
|
3. 禁止该 login role 建立新连接；
|
||||||
|
4. 终止该 database 的现有连接；
|
||||||
|
5. 删除 database，database 内 extension 随之删除；
|
||||||
|
6. 删除 login role；
|
||||||
|
7. 删除 OpenBao KV 记录及其可恢复版本；
|
||||||
|
8. 回读确认外部资源均不存在；
|
||||||
|
9. 删除 controller registry 记录；
|
||||||
|
10. 移除 finalizer，允许 Kubernetes 删除 CR。
|
||||||
|
|
||||||
|
任一步失败都必须保持 finalizer 并从安全检查开始重试。controller 禁止使用
|
||||||
|
`CASCADE` 删除无法证明属于该 Tenant 的依赖对象。若 Instance 或 OpenBao 永久丢失，
|
||||||
|
管理员可以在核实外部状态后手工移除 finalizer；该逃生操作必须在运维 runbook 中明确
|
||||||
|
标记为可能遗留资源。
|
||||||
|
|
||||||
|
v1alpha1 不自动检查备份，也不承诺恢复被 `Delete` 删除的数据。显式选择 Delete 的
|
||||||
|
用户承担数据销毁语义；默认 Retain 用于避免普通误删。
|
||||||
|
|
||||||
|
## 12. 现有环境迁移
|
||||||
|
|
||||||
|
v1alpha1 不接管现有 database 或 role，但必须提供可重复、可回滚的迁移 runbook。对每
|
||||||
|
个现有应用租户，推荐的停机迁移顺序是：
|
||||||
|
|
||||||
|
1. 盘点 database、role、owner、grant 和 extension，并完成可恢复备份；
|
||||||
|
2. 创建逻辑备份，必须使用可映射到新 owner 的格式，避免恢复旧 role ownership；
|
||||||
|
3. 停止应用写入并确认没有活动写事务；
|
||||||
|
4. 完成最终逻辑备份；
|
||||||
|
5. 将旧 database 和 role 重命名为带迁移时间戳的保留名称，释放最终名称；
|
||||||
|
6. 创建 `PostgreSQLTenant`，由 controller 创建最终 database、role 和 OpenBao 凭据；
|
||||||
|
7. 等待 Tenant Ready；
|
||||||
|
8. 以新 owner 恢复逻辑备份，并验证 row count、schema、extension 和应用权限；
|
||||||
|
9. 让 ESO 投射新凭据，重启或重新部署应用；
|
||||||
|
10. 验证应用读写后结束维护窗口；
|
||||||
|
11. 保留旧 database、role 和备份直到回滚窗口结束，再由管理员手工清理。
|
||||||
|
|
||||||
|
回滚时停止新应用写入、恢复原名称或连接配置，并重新使用旧凭据。迁移工具不得把旧
|
||||||
|
密码、管理凭据或 dump 文件提交到 Git。真实命令、锁定方式和各现有应用验证项见
|
||||||
|
[`migration.md`](migration.md)，并必须在实现首个可用版本前通过临时 PostgreSQL 实例
|
||||||
|
演练。
|
||||||
|
|
||||||
|
## 13. 安全要求
|
||||||
|
|
||||||
|
1. 所有 PostgreSQL 与 OpenBao 网络访问必须支持超时和 context cancellation。
|
||||||
|
2. homelab 部署必须通过 Deployment 挂载的共享 CA bundle 验证 TLS server identity；
|
||||||
|
该 bundle 的信任根来自 OpenBao PKI，但不得包含 CA 私钥。Instance 默认使用
|
||||||
|
`verify-full`，其 host 必须与服务器证书名称匹配。开发环境可以显式使用 `disable`
|
||||||
|
明文连接。
|
||||||
|
3. PostgreSQL 管理 role 应使用满足本规格的最小权限，不应使用 PostgreSQL
|
||||||
|
superuser；若 extension 安装需要额外权限，必须单独记录例外。
|
||||||
|
4. controller 的 OpenBao policy 仅覆盖受管租户 KV 操作，不授予管理凭据路径权限。
|
||||||
|
管理凭据的 ESO 同步身份与应用凭据的 ESO 读取身份隔离。controller 只在自身
|
||||||
|
namespace 获得管理 Secret 读取权限，不因此扩大跨 namespace Secret data 访问范围。
|
||||||
|
5. namespace 用户不得修改 cluster-scoped Instance。
|
||||||
|
6. 所有 identifier、extension name 和引用字段必须在发起外部调用前校验。
|
||||||
|
7. controller 不得通过 shell 或 `psql` 子进程执行用户输入。
|
||||||
|
8. 错误包装、结构化日志和 tracing 必须经过 Secret 泄露测试。
|
||||||
|
|
||||||
|
详细威胁模型和部署 policy 见 [`security.md`](security.md)。
|
||||||
|
|
||||||
|
## 14. 可观测性要求
|
||||||
|
|
||||||
|
v1alpha1 至少必须提供：
|
||||||
|
|
||||||
|
- Kubernetes Events：开始 provisioning、成功及需要人工处理的失败；
|
||||||
|
- 结构化日志：resource namespace/name、Instance、generation、阶段和错误类别；
|
||||||
|
- controller-runtime 默认 reconcile metrics；
|
||||||
|
- 不包含 database、role、OpenBao path 等无界用户输入的低基数失败分类 metric。
|
||||||
|
|
||||||
|
日志和 metrics 的存在不能代替 Condition；Condition 是 API 使用者判断状态的主要方式。
|
||||||
|
|
||||||
|
## 15. 验收标准
|
||||||
|
|
||||||
|
实现 v1alpha1 第一条完整纵向切片前，测试必须覆盖：
|
||||||
|
|
||||||
|
1. 有效 Instance 可以建立 TLS 管理连接并变为 Ready。
|
||||||
|
2. PostgreSQL 管理能力不可用时 Instance Ready=False，恢复后自动变为 Ready；已有
|
||||||
|
管理凭据可正常使用时，Bao／ESO 故障不单独影响 Instance Ready。首次装配缺少有效
|
||||||
|
管理 Secret 时不能 Ready；Tenant 的 Bao 操作失败按其自身依赖故障报告。
|
||||||
|
3. 有效 Tenant 创建 database、作为 owner 的 login、grant、extension 和 OpenBao
|
||||||
|
记录。
|
||||||
|
4. 应用凭据可以实际连接且不能创建其他 database/role。
|
||||||
|
5. 相同 generation 重复 reconcile 不改变密码、不重复创建资源。
|
||||||
|
6. controller 在每个外部写入步骤后中断，重启后都能继续并得到相同最终状态。
|
||||||
|
7. 预先存在且不属于当前 Tenant UID 的 database、role 或 OpenBao path 导致
|
||||||
|
Conflict，且不修改已有资源。
|
||||||
|
8. 目标实例实际不支持的 extension 在供应外部写入前被拒绝；扩展列表查询失败时
|
||||||
|
按依赖故障处理，不报告为不支持。安装结果仍须回读验证。
|
||||||
|
9. status 被清空后可以从两个外部事实来源重建。
|
||||||
|
10. 删除 Retain Tenant 后外部资源仍存在且不再受管；重新创建同名 Tenant 报告
|
||||||
|
Conflict。
|
||||||
|
11. 日志、Event、Condition、metric 和 CR 中不存在生成的密码或管理凭据。
|
||||||
|
12. 两个 namespace 对同一 Instance 申请相同名称时，只有第一个成功，第二个报告
|
||||||
|
Conflict。
|
||||||
|
13. 删除 Delete Tenant 时，任一步骤失败都可重试，且最终删除 database、login role、
|
||||||
|
OpenBao KV 历史和 finalizer。
|
||||||
|
14. 使用迁移 runbook 可以把一个现有 database 转移到新建的受管 database，并在回滚
|
||||||
|
窗口内恢复旧服务。
|
||||||
|
15. Tenant 只有在 ExternalSecret Ready、目标 Secret 存在且应用凭据实际可登录后才
|
||||||
|
Ready。
|
||||||
|
16. Tenant status 同时提供 Kubernetes Secret reference 和不含认证信息的 OpenBao API
|
||||||
|
URL。
|
||||||
|
17. DNS 不可用时，使用输出的 `hostaddr` 可以连接 PostgreSQL；server 证书同时覆盖
|
||||||
|
`host` 的 DNS SAN 和 `hostaddr` 的 IP SAN，两种连接目标均可通过 `verify-full`。
|
||||||
|
18. 两个 CR 的 `status.phase` 都能反映当前协调步骤；清空 status 后可以从外部事实重建，
|
||||||
|
且伪造或过期 phase 不会使 controller 跳过验证或外部操作。
|
||||||
|
|
||||||
|
单元测试验证纯决策逻辑，adapter 集成测试使用 Docker PostgreSQL/OpenBao，controller
|
||||||
|
集成测试使用 envtest，完整网络路径使用 Kind E2E。
|
||||||
|
|
||||||
|
## 16. 已确认决策
|
||||||
|
|
||||||
|
- v1alpha1 使用一个同时作为 database owner 的 login role，不创建额外 NOLOGIN owner。
|
||||||
|
- v1alpha1 不接管任意现有资源，但必须提供并演练 dump/restore 迁移路径。
|
||||||
|
- v1alpha1 同时实现默认 `Retain` 和显式 `Delete`；Delete 必须有 finalizer、所有权验证
|
||||||
|
和完整清理路径。
|
||||||
|
- OpenBao KV v2 mount 和 base path 是 controller 部署配置，mount 默认 `kv`，base path
|
||||||
|
由 `--openbao-tenant-base-path` 配置并默认 `postgresql-tenants`；Tenant 不能选择 mount
|
||||||
|
或任意远端 path，controller 根据 namespace/name 推导记录路径。
|
||||||
|
- 租户 KV 记录固定写入 `username/password/database/host/hostaddr/port/sslmode` 七个
|
||||||
|
原子字段；
|
||||||
|
controller 不生成连接 URI，应用负责映射和拼装自身配置。
|
||||||
|
- PostgreSQL TLS 使用 controller Deployment 挂载的共享 CA bundle。OpenBao PKI 是
|
||||||
|
CA 权威并继续签发、续期 PostgreSQL server 证书；controller 只消费公开 trust
|
||||||
|
bundle，不接触 CA 私钥。bundle 可以由 ConfigMap 或现有证书同步机制投射，不允许
|
||||||
|
Tenant 或 Instance 选择其他 CA；开发环境可以显式使用 `sslMode: disable`。
|
||||||
|
- 每个 PostgreSQLInstance 在其管理 database 中维护 controller 专用 registry schema。
|
||||||
|
registry 是受管资源所有权、安装身份和 Retain 后 unmanaged 标记的权威记录；两个
|
||||||
|
CR 的 `status.phase` 是 controller 状态机的权威 checkpoint，Instance status 不聚合
|
||||||
|
Tenant 清单。
|
||||||
|
- PostgreSQL database 和 role identifier 必须匹配 `^[a-z][a-z0-9_]{0,62}$`，不支持
|
||||||
|
需要双引号的大小写或特殊字符名称。
|
||||||
|
- External Secrets Operator 是 v1alpha1 的运行依赖。controller 管理同 namespace
|
||||||
|
ExternalSecret，但不直接写明文 Secret；Tenant status 同时输出目标 Secret reference
|
||||||
|
和供非 Kubernetes 消费者使用的 OpenBao API URL。
|
||||||
|
- PostgreSQLInstance 同时声明 DNS `host` 和 IP `hostaddr`；PostgreSQL server 证书必须
|
||||||
|
同时包含对应 DNS SAN 和 IP SAN，消费者自行选择连接目标。
|
||||||
|
|
||||||
|
## 17. 批准状态
|
||||||
|
|
||||||
|
2026-09-14 确认 extension 判定修订：v1alpha1 使用实例实际可安装列表，不实现管理员
|
||||||
|
allowlist；后续可按需引入策略。现有 allowedExtensions 字段尚待 API 实现移除。
|
||||||
|
|
||||||
|
2026-09-13 已确认管理连接修订：Instance 引用 controller namespace 内的管理 Secret，
|
||||||
|
管理员维护 ExternalSecret，由 ESO 同步；controller 不再从 Bao 直接读取管理凭据。
|
||||||
|
此项是已批准行为，现有 API types 与实现尚待后续修改。
|
||||||
|
|
||||||
|
具体设计决策和本文整体已于 2026-09-10 获得批准，可以进入 API reference、测试和
|
||||||
|
实现阶段。同日确认状态机修订：两个 CR 的 `status.phase` 是 controller 工作流的权威
|
||||||
|
checkpoint；PostgreSQL registry 只承担所有权、安装身份和保留状态。
|
||||||
|
|
||||||
|
## 18. 与当前脚手架的已知差异
|
||||||
|
|
||||||
|
当前 API skeleton 至少需要以下调整：
|
||||||
|
|
||||||
|
- 删除 Tenant 自选 OpenBao path 的能力，改由部署级 mount、base path 和 Tenant
|
||||||
|
identity 推导，并修正当前包含 `kv/` 前缀的示例；
|
||||||
|
- 增加 controller 部署级 OpenBao KV mount 和 TLS 配置；
|
||||||
|
- 增加部署级 OpenBao consumer address、ClusterSecretStore 和 KV base path 配置；
|
||||||
|
- 删除独立 `ownerRole` 字段，使 login role 成为 database owner；
|
||||||
|
- 为 Instance 增加 `hostaddr`，为 Tenant 增加目标 Secret 配置及 Secret/Bao URL 输出
|
||||||
|
status；
|
||||||
|
- 按已确认的 identifier 合同收紧校验；
|
||||||
|
- 增加 PostgreSQL controller registry，记录基于 UID 的所有权、安装身份和保留状态；
|
||||||
|
- 修正凭据 type 中遗留的 rotation 注释；
|
||||||
|
- 使 Condition、不可变字段和 extension 追加语义具备 API 校验或明确的 reconcile
|
||||||
|
结果。
|
||||||
|
|
||||||
|
这些是规格批准后的实现工作，不属于本规格本身。
