A Kubernetes cluster is the set of nodes or machines that are running the applications. You can create clusters on both physical and virtual machines.
Stuff you wanna know:
- A Kubernetes cluster consists of the components that represent the control plane – the API server, the scheduler, the controller manager, the kubelet, the kube-proxy, and etcd.
- Every cluster has at least one worker node. The worker nodes host the Pods that are the components of the application workload.
- The master node of the cluster is responsible for maintaining its state.
- A cluster can have more than one namespace.
- The Kubernetes control plane schedules cluster activity and manages the worker nodes and the Pods in the cluster.
