Kubernetes enables you to deploy multiple instances of your application as required and allows easy communication between different services within your application by hosting your applications as containers in an automated manner.

kubectl¶

kubectl is a command line tool used to interact with Kubernetes clusters, using the Kubernetes API. It allows you to run commands (deploy or manage applications) against Kubernetes clusters. It looks for a file in $HOME/.kube for configuration.

kubectl cluster-info # get cluster information
kubectl get nodes # get nodes information in the cluster
