summary

New Relic runs a cell-based Kubernetes platform across 270+ clusters and ~18,000 nodes, using Cluster API for declarative bootstrapping, kind jobs + clusterctl to install controllers, and clusterctl move to hand off self-management; machine pool Helm charts expose node creation and Carpenter handles groupless bin‑packing while Argo CD manages control‑plane apps. Scheduling requirements encode as scheduling classes via a mutating webhook. Result: repeatable, automated cluster lifecycle and smaller blast radii in production, with ongoing pain points around CAPI/cloud-provider version drift.
