Podman Build And Publish Action

Composite action that builds and optionally pushes OCI images with Podman to registry.noctrl.eu.

Inputs

• image-name (required): repository path, for example noctrl/gitea-runner
• tags (required): newline, comma, or space separated tags
• context (optional, default .): build context
• containerfile (optional, default Containerfile): containerfile path
• build-args (optional): newline-separated KEY=VALUE
• push (optional, default true): whether to push image tags

Required Secrets

The following repository secrets must be defined to push images:

• REGISTRY_USERNAME: registry authentication username
• REGISTRY_PASSWORD: registry authentication password

The action uses fixed Podman defaults matching the runner workflows:

• root: ${RUNNER_TEMP}/podman-root
• runroot: ${RUNNER_TEMP}/podman-runroot
• storage driver: vfs
• build isolation: chroot
• registry: registry.noctrl.eu (hardcoded)

Example

jobs:
  build-and-push:
    runs-on: [linux, build]
    steps:
      - name: Checkout
        uses: actions/checkout@v4

      - name: Build and push image
        uses: https://gitea.noctrl.eu/noctrl/actions/podman-build-publish@v1
        with:
          image-name: noctrl/gitea-runner
          tags: |
            latest
            sha-${{ github.sha }}
          context: .
          containerfile: Containerfile
          build-args: |
            ACT_RUNNER_VERSION=0.2.11
          push: "true"

Note: The action accesses ${{ secrets.REGISTRY_USERNAME }} and ${{ secrets.REGISTRY_PASSWORD }} from the calling repository's secrets context. These must be defined in the caller's repository settings.
