action-label-syncer: A Go repository from micnncim

GitHub Actions workflow to sync GitHub labels in the declarative way.

By using this workflow, you can sync current labels with labels configured in a YAML manifest.

Usage

Create YAML manifest of GitHub labels

- name: bug
  description: Something isn't working
  color: d73a4a
- name: documentation
  description: Improvements or additions to documentation
  color: 0075ca
- name: duplicate
  description: This issue or pull request already exists
  color: cfd3d7

The default file path is .github/labels.yml, but you can specify any file path with jobs.<job_id>.steps.with.manifest.

To create manifest of the current labels easily, using label-exporter is recommended.

Create Workflow

An example workflow is here.

name: Sync labels
on:
  push:
    branches:
      - master
    paths:
      - path/to/manifest/labels.yml
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: micnncim/action-label-syncer@v1
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        with:
          manifest: path/to/manifest/labels.yml

If a label color or description changes, the same label is updated with the new color or description. If a label name changes, the previous label is deleted by default. Also all existing labels which not listed in manifest will be deleted by default. All issues and PRs that were previously labeled with this label are now unlabeled.

You can add jobs.<job_id>.steps.with.prune: false in order to preserver all existing labels which is not mentioned in manifest, in this case when a label will be renamed old label will be not deleted.

Sync labels on another repository

It is also possible to specify a repository or repositories as an input to the action. This is useful if you want to store your labels somewhere centrally and modify multiple repository labels.

Note: The default GITHUB_TOKEN will not have permissions to operate on other repositories so you must specify a personal access token in your secrets.

name: Sync labels
on:
  push:
    branches:
      - master
    paths:
      - path/to/manifest/labels.yml
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: micnncim/action-label-syncer@v1
        with:
          manifest: path/to/manifest/labels.yml
          repository: |
              owner/repository-1
              owner/repository-2
          token: ${{ secrets.PERSONAL_TOKEN }}
