Deploying CI/CD Infrastructure with Terraform and Packer
summary
Builds a production-ready pool of self-hosted runners on GCP using Terraform + Packer, Cloud Functions for scale-up/scale-down, and image baking to remove VM setup time; claims roughly a 5x raw VM cost saving versus GitHub-hosted runners (example $350 -> $70) and an efficiency target where idle time stays under four times job time. Deployed as modules plus packer images, runs 100+ private repos since November with daily health checks, monitoring and automated retries, and reports no major incidents.
