docker-build-action

Builds the docker image and uploads it to a repository.

Usage

  - uses: ./.github/actions/docker-build
    with:
      context:                 # (OPTIONAL) Directory context for building (default: .)
      repository_server:       # Any docker registry like dockerhub.com or quay.io
      repository_name:         # project name in the repo
      repository_username:     # bot/user name for the repository
      repository_password:     # bot / user password for the repository
      docker_tag:              # tag for the image
      docker_cache_tag:        # generic tag used for caching images (branch or similar, see example)
      dockerfile:              # (OPTIONAL) Location of the dockerfile (default is ${context}/Dockerfile)
      docker_args:             # (OPTIONAL) additional options to pass to docker (see example)

Example

An example for a simple repository that only has one Dockerfile at the root of the repo. For more complicated setups you may need to add the context and dockerfile.

This example uses the git-version-action, which provides the version based on commit and the branch name. Neither is necessary for using this action, but is useful for illustrating how one might use docker_tag and docker_cache_tag.
