action/image-deploy

Composite Gitea Action that pins an image tag in fritzlab/apps via kustomize edit set image, validates the rendered manifests, and pushes to apps-repo main. Retries on push conflict.

This is the standard "deploy" step for image producers (chrony, profiles, runner). After image-build + image-push, this writes the new tag into the GitOps target so ArgoCD can sync it.

Usage

- uses: actions/checkout@v4
- uses: https://code.fritzlab.net/action/image-build@v1
  with:
    image: code.fritzlab.net/fritzlab/chrony
    smoke-test: docker run --rm --entrypoint /usr/sbin/chronyd $IMAGE -v
- uses: https://code.fritzlab.net/action/image-push@v1
  with:
    image: code.fritzlab.net/fritzlab/chrony
    token: ${{ secrets.CI_BOT_TOKEN }}
    org: fritzlab
    name: chrony
- uses: https://code.fritzlab.net/action/image-deploy@v1
  with:
    image: code.fritzlab.net/fritzlab/chrony
    path: sjc001/infra/chrony/manifests
    token: ${{ secrets.CI_BOT_TOKEN }}

Inputs

Name	Required	Default	Description
image	yes	—	Full image name without tag. Must match an entry already in the target kustomization.yaml images: block.
tag	no	github.run_number	Tag to pin.
path	yes	—	Path inside fritzlab/apps to the manifests dir (e.g. sjc001/infra/chrony/manifests).
token	yes	—	CI_BOT_TOKEN with write access to fritzlab/apps.
apps-repo	no	code.fritzlab.net/fritzlab/apps	Apps repo URL without protocol.
message	no	deploy <name> #<tag>	Commit message override.

Behavior

1. Shallow-clone fritzlab/apps to a temp dir.
2. cd <path> and run kustomize edit set image <image>=<image>:<tag>.
3. Run kustomize build . to validate the manifests still render. Fails the workflow if validation breaks — apps repo is left untouched.
4. If no diff (apps repo already on this tag): exit 0 silently.
5. Otherwise commit + push to main. On push rejection (concurrent CI race), git pull --rebase and retry up to 3 times with linear backoff.

Notes

• The image entry must already exist in kustomization.yaml. This action only updates the tag; it does not add or remove image entries. To switch image registry paths, edit kustomization.yaml by hand once, commit, then let CI resume.
• git diff --quiet skip means re-running the same CI run (or an earlier run) is idempotent.
