How to check kubectl status

 kubectl cluster-info

Below are the commands to get cluster status based on requirements:

• To get information regarding where your Kubernetes master is running at, CoreDNS is running at, kubernetes-dasboard is running at, use kubectl cluster-info

• To get detailed information to further debug and diagnose cluster problem, use kubectl cluster-info dump

• To get only the health status for your node use, kubectl get componentstatus or kubectl get cs

*To show detailed information about a resource use kubectl describe node <node>

The below command would display the health of scheduler, controller and etcd

kubectl get cs

Command below lists Kubernetes core components like, etcd, controller, scheduler, kube-proxy, core-dns, network plugin. All those pods should be running to be sure that Kubernetes is healthy.

kubectl get pod -n kube-system

Finally deploy one front-end and back-end Pod and verify the inter-pod communication to ensure that cluster is up and working correctly.
