Enabling Autocompletion

To enable autocompletion for kubectl commands, follow the instructions for your shell:

Bash
Zsh

Connecting to a Cluster with kubeconfig

Obtain the kubeconfig file from your cluster administrator or cloud provider.
Create the folder mkdir -p $HOME/.kube and copy your kubeconfig file to config. cp kubeconfig $HOME/.kube/config $HOME/.kube/config is the default location where kubernetes checks the config file Another approach is by setting an env
Set the KUBECONFIG environment variable:

export KUBECONFIG=/path/to/kubeconfig

Verify that you can connect to the cluster:

kubectl cluster-info

Checking Context and Nodes

Check the current context:

kubectl config current-context

List all available contexts:

kubectl config get-contexts

Get information about the nodes in the cluster:

kubectl get nodes -o wide
