Hello! I’m using GitHub - philips-labs/terraform-aws-github-runner: Terraform module for scalable GitHub action runners on AWS to create self-hosted Runners inside AWS. This code has the feature that it uses EC2 Spot instances, can bring up and then can bring down the set of active Runners to zero (so no cost when Runners are not active). To be able to bring the set of Runners down to zero, yet still have GitHub able to trigger the webhook to the AWS API Gateway, an ‘offline runner’ must be created.
What I’ve seen is that sometimes this ‘offline runner’ mysteriously disappears from the GitHub Organization I create it in. Is there a timeout that is triggered to prune ‘offline runners’ from a Repository or Organization? Is there a log of this activity somewhere? Is there any way to ensure that an ‘offline runner’ is never purged from an Organization’s Runner list?
Thanks in advance! This is a head-scratcher!
