Pack Github Action

This Github Action uses the Pack CLI (a product of the Cloud Native Buildpacks project) to build applications and associated artifacts, without a Dockerfile. For more about pack concepts, see the pack docs. For pack usage specific documentation, see the Pack CLI docs.

In v2, login is no longer included in the action. Instead, users should use the docker/login-action in another step beforehand, and this action should pick up those credentials

In v2, you must use the direct path within the directory, without the /github/workspace/ preface

Remote Build

  dockerhub_remote_build:
    runs-on: ubuntu-latest
    env:
      USERNAME: '<SOMETHING>'
      IMG_NAME: '<SOME_IMG>'
    steps:
      - name: Checkout
        uses: actions/checkout@v2
      - name: Set App Name
        run: 'echo "IMG_NAME=$(echo ${USERNAME})/$(echo ${IMG_NAME})" >> $GITHUB_ENV'
      - name: login
        uses: docker/login-action@v1
        with:
          username: ${{ env.USERNAME }}
          password: ${{ secrets.DOCKER_TOKEN }}
      - name: Pack Remote Build
        uses: dfreilich/pack-action@v2
        with:
          args: 'build ${{ env.IMG_NAME }} --builder paketobuildpacks/builder:full --publish'

If you are publishing to a registry that is not Docker Hub, you can also add in an optional registry argument:

  github_registry_remote_build:
    runs-on: ubuntu-latest
    env:
      USERNAME: '<NAME>'
      IMG_NAME: '<IMAGE>'
      REGISTRY: '<REGISTRY: ex. ghcr.io>'
    steps:
      - name: Checkout
        uses: actions/checkout@v2
      - name: Set App Name
        run: 'echo "IMG_NAME=$(echo ${REGISTRY})/$(echo ${USERNAME})/$(echo ${IMG_NAME})" >> $GITHUB_ENV'
      - id: login
        uses: docker/login-action@v1
        with:
          username: ${{ env.USERNAME }}
          password: ${{ secrets.GH_PACKAGES_PAT }}
          registry: ${{ env.REGISTRY }}
      - name: Pack Remote Build
        uses: dfreilich/pack-action@v2
        with:
          args: 'build ${{ env.IMG_NAME }} --builder ${{ env.BUILDER }} --publish'
