| 1 | The first thing to internalize about Kubernetes is that it has two planes, not one. The control plane makes global decisions and holds the desired state of every API object. The data plane runs the actual workloads, one or more worker nodes carrying the Pods. The spine connecting them is the API server, and every line that crosses from one plane to the other must pass through it. Hold that picture in your head — every later drawing is a zoom into one part of it. |
