.prowlabels.yaml

A .prowlabels.yaml file is necessary for most of the labeling commands & jobs:

Review and Approve Pull Requests

Below is an example of how to use an OWNERS file with the Prow action.

Add an OWNERS file to the root of the repository in the default branch.

# List of usernames who may use /lgtm
reviewers:
  - user1
  - user2
  - user3

# List of usernames who may use /approve
approvers:
  - user1
  - user2
  - admin1

Grant the default GITHUB_TOKEN permission to label issues and review pull requests.

name: Handle prow slash commands
on:
  issue_comment:
    types: [created]

# Grant additional permissions to the GITHUB_TOKEN
permissions:
  # Allow labeling issues
  issues: write
  # Allow adding a review to a pull request
  pull-requests: write

  execute:
    runs-on: ubuntu-latest

      - uses: jpmcb/prow-github-actions@v1
        with:
          prow-commands: |
            /approve
            /lgtm
          github-token: '${{ secrets.GITHUB_TOKEN }}'
