Kuberenetes consists of a master, worker nodes and workstation (pc that developer uses to send commands to control plane/master)
Master has the following components:
- API Server (Communicates with every other component in the control plane aka master)
- Etcd (Cluster store -> stores information about the cluster (The desired state))
- Controller Manager (Probes all the pods in the cluster to check for their health)
- Scheduler (Schedules tasks that are to be executed by the worker nodes)
Worker has the following components:
- Kubelet (It’s a kuberenetes agent that instatiates pods in a node, works with API server)
- Container Engine (Docker/rkt)
- Kube Proxy (Works with API server to create entries in IP table -> unique IP for every pod)
