Question

Compare between Kubernetes Master node & Kubernetes Worker node

Answer 1

Answer:------------

Compare between Kubernetes Master node & Kubernetes Worker node:---------------

• The master node does not run any containers, it just handles and manages the cluster. The nodes that actually run the containers are the worker nodes..There’s a kube-proxy instance in each node. That means there’s one on the worker nodes too. It’s configuration specifies the master nod. Nothing fancy. It’s configuration can be found here.

Kubernetes Master node:-----
It is the entry point for all administrative tasks which is responsible for managing the Kubernetes cluster. There can be more than one master node in the cluster to check for fault tolerance. More than one master node puts the system in a High Availability mode, in which one of them will be the main node which we perform all the tasks.

For managing the cluster state, it uses etcd in which all the master nodes connect to it.
Components of a master node:-------
API server:
Scheduler:
Controller manager:
ETCD:

Kubernetes Worker node:-------
It is a physical server or you can say a VM which runs the applications using Pods (a pod scheduling unit) which is controlled by the master node. On a physical server (worker/slave node), pods are scheduled. For accessing the applications from the external world, we connect to nodes.
Components of a worker node:-------
Container runtime:
Kubelet:
Kube-proxy:
pods:
