$ kubectl config current-context

List all contexts in a kubeconfig file:

$ kubectl config get-contexts

Switch context:

$ kubectl config use-context <context_name>

A Pod is a group of one or more containers with shared storage, network, and lifecycle and is the basic deployable unit in Kubernetes.
