Dave Kowalski cc717790f7 untag built image after push to bound the dind image store

image-build loads each build into the runner pod's dind (load: true); the
tags then accumulated forever (dozens of stale 2-3GB tags per pod, a chunk
of the runner disk growth). Untag after a successful push and sweep the
now-dangling previous :latest. The buildkit build cache is separate and
refcounts its own layers, so the next build stays warm; when the repo is
'runner' itself the pod's next job re-pulls the ~380MB job image from the
local registry (cheap). Guarded (continue-on-error + || true) so cleanup
never fails a release.

action/image-push

Composite Gitea Action that pushes a locally-built image to code.fritzlab.net and prunes old numeric tags via the Gitea package API.

Pair with action/image-build — image-build loads the image to the runner's local Docker daemon, image-push uploads it.

Usage

- uses: actions/checkout@v4
- uses: https://code.fritzlab.net/action/image-build@v1
  with:
    image: code.fritzlab.net/fritzlab/chrony
- 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

Inputs

Name	Required	Default	Description
`image`	yes	—	Full image name without tag.
`tag`	no	`github.run_number`	Tag to push (must already exist locally).
`token`	yes	—	`CI_BOT_TOKEN` — registry login + cleanup API.
`org`	yes	—	Gitea org for package API (`fritzlab`, `dns`).
`name`	yes	—	Package name as registered in the registry.
`latest`	no	`true`	Also push a `:latest` tag.
`keep`	no	`3`	Numeric tags to retain. Older are deleted.

Behavior

docker login code.fritzlab.net as ci-bot.
docker push <image>:<tag>.
If latest=true, also docker push <image>:latest.
Prune: list numeric tags from Gitea package API, keep the newest keep, delete the rest. Failures here do not fail the workflow (continue-on-error: true).
