The worker node: The muscle
Kubernetes worker nodes are a fundamental part of a Kubernetes cluster as they are responsible for running and managing Pods, the smallest deployable units of a Kubernetes application. Worker nodes execute containers, communicate with the control plane, and collectively form the infrastructure on which applications run. While the control plane infrastructure components take care of the cluster itself and all internals, the worker nodes execute application containers running inside the cluster.
This is why it’s also important to understand what Kubernetes component worker nodes consist of and how they function.
Figure 2.2 shows the components of a worker node.
