Publish Docker Action

Publish Docker Action is used to build, tag and publish docker image to your docker registry.

Usage

This simple example will use Dockerfile in your workspace to build image, attach the latest tag and push to docker default registry (docker.io). Repository name is your GitHub repository name by default.

- uses: wuhan005/publish-docker-action@master
  with:
    username: ${{ secrets.DOCKER_USERNAME }}
    password: ${{ secrets.DOCKER_PASSWORD }}

Use file and path arguments to set docker build file or build context if they are not placed in the default workspace direcotry.

Set up registry and repository name

Registry and repository name can be changed with registry and repository arguments. For example:

- uses: wuhan005/publish-docker-action@master
  with:
    username: ${{ secrets.DOCKER_USERNAME }}
    password: ${{ secrets.DOCKER_PASSWORD }}
    registry: docker.pkg.github.com
    repository: jerray/publish-docker-action

Tag Format

When you set auto_tag to true, you can customize the image's tag.

Use tag_format to format the tag. Default is "%TIMESTAMP%"

Format signs:

%TIMESTAMP%     Timestamp
%YYYY%          Year
%MM%            Month
%DD%            Day
%H%             Hour
%m%             Minute
%s%             Second

- uses: wuhan005/publish-docker-action@master
  with:
    username: ${{ secrets.DOCKER_USERNAME }}
    password: ${{ secrets.DOCKER_PASSWORD }}
    registry: docker.pkg.github.com
    repository: wuhan005/publish-docker-action
    auto_tag: true
    tag_format: "foo%YYYY%_%MM%"

And an image with the tag foo2019_9 will be published.

Cache

Cache image can be used to build image. Just provide with.cache argument.
