Kubernetes architecture
Kubernetes is made of a cluster of nodes. There are two possible roles for nodes in Kubernetes – control plane nodes and worker nodes. The control plane nodes control the Kubernetes cluster, scheduling the workloads, listening to requests, and other aspects that help run your workloads and make the cluster function. They typically form the brain of the cluster.
On the other hand, the worker nodes are the powerhouses of the Kubernetes cluster and provide raw computing for running your container workloads.
Kubernetes architecture follows the client-server model via an API server. Any interaction, including internal interactions between components, happens via the Kubernetes API server. Therefore, the Kubernetes API server is known as the brain of the Kubernetes control plane.
There are other components of Kubernetes as well, but before we delve into the details, let’s look at the following diagram to understand the high-level Kubernetes...
