Differences from official image:

Support for using various setup-* actions like ruby/setup-ruby and actions/setup-go.
Includes the GitHub CLI tool (gh).
Support for using docker compose/docker-compose commands.

Usage

Customize your runner to use ghcr.io/krystal/actions-runner:latest instead or ghcr.io/actions/actions-runner:latest.
