In order to be highly available, most Kubernetes clusters run with a minimum of three worker nodes. The worker nodes are where pods are scheduled and run, and each worker node has three components. The first component is the Kubelet. The Kubelet is an agent that runs on every worker node, and it makes sure that the containers in a pod have started running and are healthy. The Kubelet communicates directly with the API server in the control plane, and it is looking for newly assigned pods. The next component is the container runtime. Once the Kubelet has been assigned a new pod,…
