# spire
![Version: 0.15.1](https://img.shields.io/badge/Version-0.15.1-informational?style=flat-square) ![Type: application](https://img.shields.io/badge/Type-application-informational?style=flat-square) ![AppVersion: 1.8.5](https://img.shields.io/badge/AppVersion-1.7.2-informational?style=flat-square)
[![Development Phase](https://github.com/spiffe/spiffe/blob/main/.img/maturity/dev.svg)](https://github.com/spiffe/spiffe/blob/main/MATURITY.md#development)
A Helm chart for deploying the complete Spire stack including: spire-server, spire-agent, spiffe-csi-driver, spiffe-oidc-discovery-provider and spire-controller-manager.
**Homepage:** <https://github.com/spiffe/helm-charts/tree/main/charts/spire>
## Install notes
To do a quick non production install suitable for quick testing in something like minikube:
```shell
helm install -n spire-server spire-crds spire-crds --repo https://spiffe.github.io/helm-charts-hardened/ --create-namespace
helm install -n spire-server spire spire --repo https://spiffe.github.io/helm-charts-hardened/
```
To customize, start with a base values file and edit as needed:
```shell
curl -o your-values.yaml https://raw.githubusercontent.com/spiffe/helm-charts-hardened/main/examples/production/example-your-values.yaml
```
Then:
```shell
helm install -n spire-server spire --repo https://spiffe.github.io/helm-charts-hardened/ -f your-values.yaml
```
For production installs, please see [the production example](https://github.com/spiffe/helm-charts-hardened/tree/main/examples/production).
## Upgrade notes
### 0.16.X
The settings under "spire-server.controllerManager.identities" have all been moved under "spire-server.controllerManager.identities.clusterSPIFFEIDs.default". If you have changed any from the defaults, please update them to the new location during upgrade.
### 0.15.X
The spire-crds chart has been updated. Please ensure you have upgraded spire-crds before upgrading the spire chart.
The chart now supports multiple parallel installs of spire-controller-manager. Each install will handle all custom resources with a matching `className` field. By default this is set to `Release.Namespace-Release.Name` and the controller manager will only pick up custom resources with this `className`.
If you have not loaded any SPIRE custom resources yourself, the upgrade process will be transparent. If you have loaded your own SPIRE custom resources, set `spire-server.controllerManager.watchClassless=true` until you can update your SPIRE custom resources to have the `className` for the instance specified.
### 0.14.X
If coming from a chart version before 0.14.0, you must relabel your crds to switch to using the new spire-crds chart. To migrate to the spire-crds chart
run the following:
Replace the spire-server namespace in the commands below with the namespace you want to install the spire-crds chart in.
```shell
kubectl label crd "clusterfederatedtrustdomains.spire.spiffe.io" "app.kubernetes.io/managed-by=Helm"
kubectl annotate crd "clusterfederatedtrustdomains.spire.spiffe.io" "meta.helm.sh/release-name=spire-crds"
kubectl annotate crd "clusterfederatedtrustdomains.spire.spiffe.io" "meta.helm.sh/release-namespace=spire-server"
kubectl label crd "clusterspiffeids.spire.spiffe.io" "app.kubernetes.io/managed-by=Helm"
kubectl annotate crd "clusterspiffeids.spire.spiffe.io" "meta.helm.sh/release-name=spire-crds"
kubectl annotate crd "clusterspiffeids.spire.spiffe.io" "meta.helm.sh/release-namespace=spire-server"
kubectl label crd "controllermanagerconfigs.spire.spiffe.io" "app.kubernetes.io/managed-by=Helm"
kubectl annotate crd "controllermanagerconfigs.spire.spiffe.io" "meta.helm.sh/release-name=spire-crds"
kubectl annotate crd "controllermanagerconfigs.spire.spiffe.io" "meta.helm.sh/release-namespace=spire-server"
helm install -n spire-server spire-crds charts/spire-crds
```
## Version support
> [!Warning]
> This Chart is still in development and still subject to change the API (`values.yaml`).
> Until we reach a `1.0.0` version of the chart we can't guarantee backwards compatibility although
> we do aim for as much stability as possible.
| Dependency | Supported Versions |
|:-----------|:-------------------|
| Helm | `3.x` |
| Kubernetes | `1.22+` |
> [!Note]
> For Kubernetes, we will officially support the last 3 versions as described in [k8s versioning](https://kubernetes.io/releases/version-skew-policy/#supported-versions). Any version before the last 3 we will try to support as long it doesn't bring security issues or any big maintenance burden.

## Usage
To utilize Spire in your own workloads you should add the following to your workload:
```diff
apiVersion: v1
kind: Pod
metadata:
name: my-app
spec:
containers:
- name: my-app
image: "my-app:latest"
imagePullPolicy: Always
+ volumeMounts:
+ - name: spiffe-workload-api
+ mountPath: /spiffe-workload-api
+ readOnly: true
resources:
requests:
cpu: 200m
memory: 32Mi
limits:
cpu: 500m
memory: 64Mi
+ volumes:
+ - name: spiffe-workload-api
+ csi:
+ driver: "csi.spiffe.io"
+ readOnly: true
```
Now you can interact with the Spire agent socket from your own application. The socket is mounted on `/spiffe-workload-api/spire-agent.sock`.
