Control plane

Q: How deeply does Learn Docker in a Month of Lunches, Second Edition cover control plane?

Defines the management role and deployment flow but does not detail individual control-plane internals.

As explained in Learn Docker in a Month of Lunches, Second Edition

A Kubernetes control plane is the set of management components that maintain cluster state and coordinate workloads.

A Kubernetes control plane is the cluster’s management layer. It receives application models through the Kubernetes API and coordinates containers running on cluster nodes. section 15.1

The control plane connects everyday deployment work:

kubectl sends queries and commands to the cluster. section 15.1
Declarative YAML describes compute, networking, storage, configuration, and connections between application components. section 15.1
Management components use that model to commission containers on the machines managed as a cluster. section 15.1

Verify a local cluster

Select the Docker Desktop context with `kubectl config use-context docker-desktop`, then run `kubectl get nodes` to check the cluster machines.
