🧩 Awesome features

This document discusses the development of a Go language actions that synchronizes labels on GitHub repositories. This actions is not limited to synchronizing labels on your own repository, but can also retrieve all of the API objects of a target repository, which can then be saved to a YAML file or synchronized to your own GitHub project.

Labels are an important way of organizing and categorizing issues and pull requests on GitHub. They allow you to quickly and easily identify the status, priority, and type of each issue or pull request.

To retrieve the API objects of a GitHub project's labels, you can use the following URLs:

• To retrieve the first page of objects: https://api.github.com/repos/<owner>/<repo>/labels?page=1&sort=name-asc
• To retrieve all objects: https://api.github.com/repos/<owner>/<repo>/labels?per_page=100&page=1&sort=name-asc

Simply replace <owner> and <repo> with the owner and repository name, respectively. These URLs can be used to retrieve all of the labels associated with a project, which can then be synchronized or saved as needed.

github-label-syncer is a tool to sync labels between repos and org. The main features are:

• Feel free to pick a remote repository and fetch all its labels to a local yaml, table AND json
• Feel free to pick a remote repository and sync all of its labels to your desired project repository
• Sync labels across repositories according to configuration
• Create, update and delete labels
• Dry run to preview which labels would be created, updated or deleted
• Handle label collisions by renaming or skipping existing labels
• Support labeling pull requests and issues

Labels denger: The labels are designed semantic and standard. We provide labels for priority, type, status etc. You can refer to the label doc to get more info.

Actions Auto Sync labels

For a more convenient way, we can use actions to sync labels directly, which is faster and easier

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:
      - name: Github lables pull and synchronize
        uses: kubecub/github-label-syncer@v2.0.0
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        with:
          manifest: path/to/manifest/labels.yml

You can sync labels to multiple repositories at the same time, which is more convenient, but you'll need to provide a token.

For example, the following yaml file takes a local.github/sync_labeler.yml file and syncs it to kubecub/github-label-syncer, kubecub/log, etc. BOT_GITHUB_TOKEN is used as the token

name: Kubecub Sync labels

on:
  push:
    branches:
      - main
    # paths:
    #   - .github/sync_labels.yml

jobs:
    build:
      runs-on: ubuntu-latest
      steps:
        - name: Checkout
          uses: actions/checkout@1.0.0
        - name: Github lables pull and synchronize
          uses: kubecub/github-label-syncer@v2.0.0
          with:
            manifest: .github/sync_labeler.yml
            token: ${{ secrets.BOT_GITHUB_TOKEN }}
            repository: |
              kubecub/github-label-syncer
              kubecub/log
          env:
            GITHUB_TOKEN: ${{ secrets.BOT_GITHUB_TOKEN }}

Note: The new labels and colors will replace the old ones

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.
