In this article we will get a clarity on the Kubernetes architecture ; the control plane components and the worker node components; along with features like api-server, scheduler, etcd, and control manager. Under worker nodes, we shall cover kubectl, kubelet, and kube-proxy.
Moving on further; So what is a Kubernetes control plane? The control plane is a global…
