# 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

```yaml
- 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

1. `docker login code.fritzlab.net` as `ci-bot`.
2. `docker push <image>:<tag>`.
3. If `latest=true`, also `docker push <image>:latest`.
4. 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`).
