问题

动态 Pod runner 自身运行在 overlay 文件系统上，内层 Docker/containerd 再使用 overlay snapshotter 时 mount 返回 invalid argument。

修复

  • 内层 dockerd 使用 vfs storage driver
  • 显式禁用 containerd-snapshotter
  • 使用 Docker engine 的 default Buildx builder，不再启动另一个 docker-container BuildKit

验证

真正有效的验证是合并后由动态 Pod runner 重新运行 publish workflow；本 PR 不把本地 privileged 容器测试当作集群验证结果。

  • actionlint 通过
  • pytest: 14 passed
  • git diff --check 通过
