Kubernetes Nodes

The machines that make up a Kubernetes cluster are called nodes.

Nodes in a Kubernetes cluster may be physical, or virtual.

There are two types of nodes:

  • A Control-plane-node type, which makes up the Control Plane, acts as the “brains” of the cluster.

  • A Worker-node type, which makes up the Data Plane, runs the actual container images (via pods).

We’ll dive deeper into how nodes interact with each other later in the presentation.
