Cleanowners action

Cleanowners is a GitHub Action that is designed to help keep CODEOWNERS files current by removing users that are no longer a part of the organization. This is helpful for companies that are looking to remove outdated information in the CODEOWNERS file. This action can be paired with other CODEOWNERS related actions to suggest new owners or lint CODEOWNERS files to ensure accuracy.

This action was developed by the GitHub OSPO for our own use and developed in a way that we could open source it that it might be useful to you as well! If you want to know more about how we use it, reach out in an issue in this repository.

Use as a GitHub Action

1. Create a repository to host this GitHub Action or select an existing repository.
2. Select a best fit workflow file from the examples below.
3. Copy that example into your repository (from step 1) and into the proper directory for GitHub Actions: .github/workflows/ directory with the file extension .yml (ie. .github/workflows/cleanowners.yml)
4. Edit the values (ORGANIZATION, EXEMPT_REPOS) from the sample workflow with your information.
5. Also edit the value for GH_ENTERPRISE_URL if you are using a GitHub Server and not using github.com. For github.com users, don't put anything in here.
6. Update the value of GH_TOKEN. Do this by creating a GitHub API token with permissions to read the repository/organization and write issues or pull requests. Then take the value of the API token you just created, and create a repository secret where the name of the secret is GH_TOKEN and the value of the secret the API token. It just needs to match between when you create the secret name and when you refer to it in the workflow file.
7. Commit the workflow file to the default branch (often master or main)
8. Wait for the action to trigger based on the schedule entry or manually trigger the workflow as shown in the documentation.
