Publishes docker containers

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

Usage

Example pipeline

name: Publish Docker
on: [push]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@master
    - name: Publish to Registry
      uses: HurricanKai/Publish-Docker-Github-Action@master
      with:
        name: myDocker/repository
        username: ${{ secrets.DOCKER_USERNAME }}
        password: ${{ secrets.DOCKER_PASSWORD }}

Mandatory Arguments

name is the name of the image you would like to push
username the login username for the registry
password the login password for the registry

Optional Arguments

registry

Use registry for pushing to a custom registry

with:
  name: myDocker/repository
  username: ${{ secrets.DOCKER_USERNAME }}
  password: ${{ secrets.DOCKER_PASSWORD }}
  registry: docker.pkg.github.com

tagging

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

if: contains(github.ref, 'refs/tags/v')
with:
  name: myDocker/repository
  username: ${{ secrets.DOCKER_USERNAME }}
  password: ${{ secrets.DOCKER_PASSWORD }}
  tagging: true

snapshot

Use snapshot to push an additional image, which is tagged with {YEAR}{MONTH}{DAY}{HOUR}{MINUTE}{SECOND}{first 6 digits of the git sha}.
The date was inserted to prevent new builds with external dependencies override older builds with the same sha. When you would like to think about versioning images, this might be useful.

with:
  name: myDocker/repository
  username: ${{ secrets.DOCKER_USERNAME }}
  password: ${{ secrets.DOCKER_PASSWORD }}
  snapshot: true

dockerfile

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

with:
  name: myDocker/repository
  username: ${{ secrets.DOCKER_USERNAME }}
  password: ${{ secrets.DOCKER_PASSWORD }}
  dockerfile: MyDockerFileName

cache

Use cache when you have big images, that you would only like to build partially (changed layers).

CAUTION: This will cache the non changed parts forever. If you use this option, make sure that these parts will be updated by another job!

with:
  name: myDocker/repository
  username: ${{ secrets.DOCKER_USERNAME }}
  password: ${{ secrets.DOCKER_PASSWORD }}
  cache: true
