summary
Shows three concrete ways to see Kubernetes operate: a time-sequence diagram that traces kubectl create -f pod.yaml step‑by‑step (API server writes to etcd, scheduler binds node, kubelet pulls image and starts busybox, kubelet reports status), using Jaeger traces to follow an HTTP request through a load balancer, ingress-nginx, the meow client and meow server (reveals node IP and per-span latency), and a tactile 3D clay model of control plane networking; recommends kspan to trace Kubernetes events.
