Create tag action

Format a deploy version tag for a git repository.

The generated tag has the exact format <unix-timestamp>-<7-char-commit-sha>. Example: 1713187200-1a2b3c4

Usage

The tag is exposed both as a step output (steps.<id>.outputs.tag) and as an environment variable (env.tag). Prefer the step output — it is statically declared in action.yml, so editor tooling and workflow linters can resolve it.

jobs:
  docker:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4

      - name: Create tag
        id: tag
        uses: tweedegolf/create-tag-action@main

      - name: Use the tag
        run: echo "Tag is ${{ steps.tag.outputs.tag }}"
