A Github Action to automatically bump and tag master, on merge, with the latest SemVer formatted version.

Medium Post: Creating A Github Action to Tag Commits

Usage

name: Bump version
on:
  push:
    branches:
      - master
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@master
    - name: Bump version and push tag
      uses: anothrNick/github-tag-action@master
      env:
        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Options

Environment Variables

• GITHUB_TOKEN (required) - Required for permission to tag the repo.
• DEFAULT_BUMP (optional) - Which type of bump to use when none explicitly provided (default: minor).
• WITH_V (optional) - Tag version with v character.
• RELEASE_BRANCHES (optional) - Comma separated list of branches (bash reg exp accepted) that will generate the release tags. Other branches and pull-requests generate versions postfixed with the commit hash and do not generate any tag. Examples: master or .* or release.*,hotfix.*,master ...
• CUSTOM_TAG (optional) - Set a custom tag, useful when generating tag based on f.ex FROM image in a docker image. Setting this tag will invalidate any other settings set!

Outputs

• new_tag - The value of the newly created tag.
• tag - The value of the latest tag after running this action.

Note: This action creates a lightweight tag.

Bumping

Manual Bumping: Any commit message that includes #major, #minor, or #patch will trigger the respective version bump. If two or more are present, the highest-ranking one will take precedence.

Automatic Bumping: If no #major, #minor or #patch tag is contained in the commit messages, it will bump whichever DEFAULT_BUMP is set to (which is minor by default).

Note: This action will not bump the tag if the HEAD commit has already been tagged.

Workflow

• Add this action to your repo
• Commit some changes
• Either push to master or open a PR
• On push (or merge) to master, the action will:
  • Get latest tag
  • Bump tag with minor version unless any commit message contains #major or #patch
  • Pushes tag to github
