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
