Scalable Continuous Integration for iOS
summary
Describes an in-house CI stack of Mac Minis on AWS EC2 used at Just Eat Takeaway in 2023, builds AMIs with Packer, deploys and scales instances with Terraform, and registers runners to GitHub Actions. Covers allocating AWS Mac dedicated hosts, AMI creation, SSH/key handling, Secrets Manager + IAM for GitHub runner tokens, and a fleet-size variable that lets Terraform scale from one to five instances; reports the setup runs in production and lowers vendor costs.
