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.

username
the login username for the registry
password
the login password for the registry
tag

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
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
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
Use workdir
when you would like to change the directory for building.
with:
name: myDocker/repository
username: ${{ secrets.DOCKER_USERNAME }}
password: ${{ secrets.DOCKER_PASSWORD }}
workdir: mySubDirectory
Use buildargs
when you want to pass a list of environment variables as build-args. Identifiers are separated by comma.
All buildargs
will be masked, so that they don't appear in the logs.

env:
MY_FIRST: variableContent
MY_SECOND: variableContent
with:
name: myDocker/repository
username: ${{ secrets.DOCKER_USERNAME }}
password: ${{ secrets.DOCKER_PASSWORD }}
buildargs: MY_FIRST,MY_SECOND
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
