This Action for Docker uses the Git branch as the Docker tag for building and pushing the container to DockerHub. Hereby the master-branch is published as the latest-tag.

Usage

New workflow

name: Publish Docker
on: [push]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@master
    - name: Login to Registry
      run: docker login -u ${{ secrets.DOCKER_USERNAME }} -p ${{ secrets.DOCKER_PASSWORD }}
    - name: Publish to Registry
      uses: elgohr/Publish-Docker-Github-Action@master
      with:
        args: myDocker/repository
    - name: Logout
      run: docker logout

Optional Arguments

Use snapshot to push an additional image, which is tagged with the git sha.
When you would like to think about versioning images, this might be useful.

with:
  args: myDocker/repository
  snapshot: true

Use dockerfile when you would like to explicitly build a Dockerfile.
This might be useful when you have multiple DockerImages.

with:
  args: myDocker/repository
  dockerfile: MyDockerFileName
