On-demand self-hosted AWS EC2 runner for GitHub Actions - Shiphero's Fork

Our fork of the machulav/ec2-github-runner for the horizontally scaled CI runner of app-endpoints.

Check the internal docs.

Changes from the original

• Includes #165: "Allow providing ec2-instance-count to start multiple runners"

  We need several instances one for each portion.

• A workaround for #60: "Support multiple regions/availabilty zones if an instance type cannot be started"

  This minimizes the chance of the InsufficientInstanceCapacity error, by balancing and trying subnetworks in different subzones

• Reduce the waiting and polling intervals for the runners registering.

  This allows to save around 45' on the "start" step.
