User guide / documentation

From the team that brought you OpenFaaS - Serverless Functions Made Simple.

Core features

All features are modular and can be enabled/disabled as required:

• Generate changelogs for releases with PRs merged and commits added
• Let designated non-admin users manage Issues and PRs by commenting Derek <command> or /command
• Enforce Developer Certificate of Origin (DCO) checking (optional)
• Automatically label/flag PRs without a Description
• Label PRs from first-time contributors
• Detect spam PRs (from hacktoberfest)
• Automatically close PRs during hacktoberfest from first-time contributors

For the managed service the cost is 25USD per month. You will need to become an OpenFaaS GitHub Sponsor to gain access to the managed service. The price covers hosting, management and maintenance of the service.

How do I work?

I'm designed to be installed as a GitHub App, but don't worry - I don't need a lot of permissions. Just access to issues and Pull Requests will do.

I'm not a long-running daemon.. I'd get bored that way. I work with webhooks - so deploy me to a Serverless platform like OpenFaaS and forget about me. Just apply oil from time to time.

This is me in action with the DCO-checking feature. If I find a commit that isn't signed off then I'll let the contributor know in a comment. Normally they edit their commits and re-push within a few minutes after re-reading the message.

Inspiration for Derek

The idea for a bot that could comment on issues or respond to activity is from the docker/docker or Moby project's bot called Poule. It's a much more complex long-running daemon which uses Personal Access Tokens (so needs to run as a full GitHub login). Derek is much simpler (so hackable) and can be installed with granular permissions.
