GitHub Action: Create/update tag

Simple (docker-based) GitHub action that can be used to create/update a tag and push it to the remote.

Note

Since this is a docker-based action and GitHub currently only supports Linux-based containers running this action on Windows and Mac now needs to be supported (see #26).

Inputs

tag

Required. Tag you want to create.

message

Optional. Tag message. Default: Release $TAG.

force_push_tag

Optional. Push tag even if it already exists on the remote. Default: false. Please use with care!

tag_exists_error

Optional. Whether to throw an error when the tag already exists. Default: true. Ignored when force_push_tag is true.

no_verify_tag

Optional. Skips verifying when pushing the tag. Default: false. Please use with care!

commit_sha

Optional. Specify the commit SHA hash for tagging. By default, it utilizes the GITHUB_SHA environment variable, which typically represents the latest commit SHA hash. However, its value ultimately depends on the trigger event of the workflow. For additional details, consult the GitHub Actions documentation.

github_token

Optional. It's no need to specify it if you use checkout@v2. Required for checkout@v1 action.

gpg_private_key

Optional. Specifies the GPG private key to sign the tag with. Default: "".

gpg_passphrase

Optional. Specifies the GPG passphrase to sign the tag with. Default: "".

Outputs

tag_exists

A boolean specifying whether the tag already exists.

Environment variables

TAG_EXISTS

A boolean specifying whether the tag already exists.

Example Usage

General example

name: Create/update tag
on:
  push:
    branch: "main"
jobs:
  create-tag:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
        with:
          fetch-depth: 0
      - uses: rickstaa/action-create-tag@v1
        id: "tag_create"
        with:
          tag: "latest"
          tag_exists_error: false
          message: "Latest release"

      # Print result using the env variable.
      - run: |
        echo "Tag already present: ${{ env.TAG_EXISTS }}"

      # Print result using the action output.
      - run: |
        echo "Tag already present: ${{ steps.tag_create.outputs.tag_exists }}"

Signing Tags with GPG

To sign tags with GPG, follow these steps:

1. Generate a GPG Key

First, generate a GPG key. Once generated, export the GPG private key in ASCII armored format to your clipboard using one of the following commands based on your operating system:

• macOS:

  gpg --armor --export-secret-key joe@foo.bar | pbcopy

• Ubuntu (GNU base64):

  gpg --armor --export-secret-key joe@foo.bar -w0 | xclip -selection clipboard

• Arch:

  gpg --armor --export-secret-key joe@foo.bar | xclip -selection clipboard -i

• FreeBSD (BSD base64):

  gpg --armor --export-s[.github/workflows/update_semver.yml](.github/workflows/update_semver.yml)e your GPG passphrase.

3. Update Workflow YAML

Modify your workflow YAML file to include the GPG private key and passphrase in the gpg_private_key and gpg_passphrase inputs:

name: Create/update tag
on:
  push:
    branch: "main"
jobs:
  create-tag:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
        with:
          fetch-depth: 0
      - uses: rickstaa/action-create-tag@v1
        id: "tag_create"
        with:
          tag: "latest"
          tag_exists_error: false
          message: "Latest release"
          gpg_private_key: ${{ secrets.GPG_PRIVATE_KEY }}
          gpg_passphrase: ${{ secrets.PASSPHRASE }}

      # Print result using the env variable.
      - run: |
        echo "Tag already present: ${{ env.TAG_EXISTS }}"

      # Print result using the action output.
      - run: |
        echo "Tag already present: ${{ steps.tag_create.outputs.tag_exists }}"

This workflow will now sign tags using the specified GPG key during tag creation.
