GitHub Action to publish Docker Images to GitHub Registry

Usage examples:

Build and publish Docker Image with a head tag for the develop branch

  build-and-publish-head:
    runs-on: ubuntu-latest
    if: github.ref == 'refs/heads/develop' # Running this job only for develop branch

    steps:
    - uses: actions/checkout@v2 # Checking out the repo

    - name: Build and Publish head Docker image
      uses: VaultVulp/gp-docker-action@1.0.1
      with:
        github-token: ${{ secrets.GITHUB_TOKEN }} # Provide GITHUB_TOKEN to login into the GitHub Packages
        image-name: my-cool-service # Provide Docker image name
        image-tag: head # Provide Docker image tag

Build and publish Docker Image with a latest tag for the master branch

  build-and-publish-latest:
    runs-on: ubuntu-latest
    if: github.ref == 'refs/heads/master' # Running this job only for master branch

    steps:
    - uses: actions/checkout@v2 # Checking out the repo

    - name: Build and Publish latest Docker image
      uses: VaultVulp/gp-docker-action@1.0.1
      with:
        github-token: ${{ secrets.GITHUB_TOKEN }} # Provide GITHUB_TOKEN to login into the GitHub Packages
        image-name: my-cool-service # Provide only Docker image name, tag will be automatically set to latest

Build and publish Docker Image with a tag equal to a git tag

  build-and-publish-tag:
    runs-on: ubuntu-latest
    if: startsWith(github.ref, 'refs/tags/') # Running this job only for tags

    steps:
    - uses: actions/checkout@v2

    - name: Build and Publish Tag Docker image
      uses: VaultVulp/gp-docker-action@1.0.1
      with:
        github-token: ${{ secrets.GITHUB_TOKEN }} # Provide GITHUB_TOKEN to login into the GitHub Packages
        image-name: my-cool-service # Provide only Docker image name
        extract-git-tag: true # Provide flag to extract Docker image tag from git reference
