How to maintain neco-containers

This document describes the procedure for updating each container image.

Besides on-demand container updates, we have two regular renewal operations: Kubernetes Update and Regular Update. The target container of these operations have the following badges, so check before the operations.

In case of components whose Go source code are in neco-containers, all dependent Go modules should be updated if there is no special reason. Kubernetes-related modules such as client-go may be newer than the Kubernetes to be updated. For example, it is acceptable that client-go is v0.30 and Kubernetes is v1.29.

1. Kubernetes Update ()
   • Upgrade of Kubernetes. Besides the related components of Kubernetes, update the containers managed by CKE and some go modules.
2. Regular Update ()
   • Update in every quarter. Keeping up with the upstream version and updating the ubuntu base image.
3. CSA Update ()
   • Update by CSA team.
4. No Need Update ()
   • Used as a PoC, so regular updates are not required.

Create a patched image from the specific version

When you want to create a new image with patches to the specific version of Ceph, follow these steps.

1. Create a branch with the name ceph-vX.Y.Z from the commit you want, and push it.
   • You must follow the branch naming convention to activate the image build and push jobs.
   • If the branch already exists, you can skip this step.
2. Create a PR to the branch ceph-vX.Y.Z, and merge it.

Note

Because cephcsi container is build based on the ceph container, build the ceph container first if necessary.

Note

You can choose the latest stable Ubuntu image for runtime. upstream uses distroless as the base image for runtime, while Neco uses Ubuntu for easier debugging.

Note

You may choose the latest docker image for the build, regardless of the upstream go version. The current go compiler builds with the language version and toolchain version based on the go version specified in the go.mod file. There is no need to use an older version of the image to match go.mod. As a known issue, the upstream build script warns that test-gofmt and test-vendor are known to be sensitive to the version of Go.. However, we use the latest docker image unless the test fails.

dex
