Warning: this is a major release bump, with a new VPC being created. You are advised to upgrade either during a quiet time (no runner running, otherwise the old VPC cannot be destroyed), or simply create a new stack with that template, follow the configuration process, and then Pause the previous AppRunner service until you validate that everything is going fine. Doing it this way will allow you to easily roll back to the previous version by just removing the new stack and clicking Resume on the previous AppRunner service.

Main changes

  • Replaces RunInstances call with CreateFleet, to reduce the number of API calls and increase the chances of finding a spot instance.
  • Multi-az support (3 AZ by default for the stack). stack no longer asks for an AZ choice.
  • capacity-optimized-prioritized allocation, so that it selects the instance type from the pool with the least risk of being interrupted
  • Modify launch sequence so that instance retrieves boot details from the S3 bucket (no more user-data)
  • Make RunsOn region aware (with region label), allowing deployments of RunsOn in multiple regions

General improvements

  • Default runner types are now separated into -x64 and -arm64 variants (simplifies configuration, no need to explicitly specify image), e.g. runs-on: runs-on,runner=2cpu-linux-arm64
  • Implement new rate limiters for EC2 RunInstances and TerminateInstances operations, as well as for workflow queuing. All are configurable.
  • New ubuntu22 full images, with some more cleanup of legacy software to reduce image sizes, and use of an agent to launch the runner earlier, instead of waiting for the execution of the cloud-final service. Current timings (from workflow job created to workflow job running) with full image: x64=39s, arm64=34s
  • Add timings for when the workflow job was created on GitHub, when the workflow job webhook got received, when the workflow started to be scheduled, and when the instance was seen as pending by AWS

Fixes

  • Fix default alarm. Make threshold configurable.
  • Stack no longer requires extended IAM permissions.

Misc

  • Truncate CloudWatch dimension values to 250 chars.
  • Change runner name format (runs-on--<INSTANCE_ID>--<RANDOM>), so that it contains the instance id.
  • No more success email when service is up, since you could receive those whenever the service is scaled up by AppRunner.
  • No more cost email when service is up. Wait 24h before the first one.

Breaking changes

  • Stack requires a VPC and subnet change, so perform the upgrade in a quiet time.
  • Runners no longer defaults to the 2cpu-linux x64 runner. You always need to specify a runner label as a base.
  • Specifying an image or runner label that does not exist will now raise an error, instead of silently falling back to the default image or runner specification.
