Control Plane - CI/CD Glossary Definition
The control plane is the set of Kubernetes components that make global decisions about the cluster: the API server, scheduler, controller manager, and etcd. It maintains desired state and reconciles the cluster toward it.
In CI
A deploy job talks only to the API server (the control plane front door). If kubectl apply hangs or times out, the control plane or its credentials are usually the issue, not the worker nodes.
