Taming the Lifecycle of 100+ Kubernetes Clusters with K8s Plumber
summary
Describes managing about 100 Kubernetes clusters using a Git-backed workflow of plain Terraform files plus simple CI workflows to provision, import, and upgrade clusters across cloud and on-prem. Uses Terraform (with Helm charts applied as Terraform resources) and Git to produce reproducible cluster state, detect drift via terraform plan, and support ~5-minute onboarding for legacy clusters; daily operations aim for automated control-plane and rolling upgrades while some infrastructure edge cases remain manual.
