Let's Build Kubernetes, With a Spreadsheet and Volunteers!
summary
Builds a working Kubernetes control plane on stage using volunteers as nodes, balloons as containers and a simple spreadsheet-style database for state. Shows static pod Django on a kubelet, how etcd acts as the shared database, scheduler assigning pods to nodes, controller manager creating replica sets and services, and an Istio/Envoy initializer mutating pods. Demonstrates etcd outage prevents writes but existing pods keep running, and explains node evacuation, label-driven service misrouting and how custom CRDs use their own schedulers.
