ops-bot

This repo contains a Probot application. The application contains the plugins listed below and is deployed using the probot/serverless-lambda package via the Serverless framework.

Plugins

The plugins are listed in the src/plugins folder.

• Label Checker - Sets a status on PRs that passes if one (and only one) of the following labels from each list have been applied:
  • bug, doc, feature request, or improvement
  • breaking or non-breaking
• Release Drafter - Opens up a draft release on GitHub anytime a PR is merged to a versioned branch (i.e. branch-0.17, branch-0.18, etc.). The draft body includes a categorized changelog consisting of the PRs that have been merged on that branch.
• Auto Merger - Automatically merges PRs that include the /merge comment and meet the merge criteria outlined in https://docs.rapids.ai/resources/auto-merger/.
• Branch Checker - Set a status on PRs that checks whether they are targeting either the repo's default branch or default branch + 1
• Recently Updated - Sets a status on PRs based on whether a PR is X commits out-of-date compared to the based branch. X defaults to 5, but is configurable via the recently_updated_threshold option in the .github/ops-bot.yaml configuration file.
