Ref: Organizing Cluster Access Using kubeconfig Files
A file that is used to configure access to clusters is called a kubeconfig file. With kubeconfig files, you can organize your clusters, users, and namespaces. You can also define contexts to quickly and easily switch between clusters and namespaces.
By default, kubectl looks for kubeconfig in this location $HOME/.kube/config.
You can use kubectl config view to see the contents of this file.
You can specify other kubeconfig files by setting the KUBECONFIG environment variable or by setting the --kubeconfig flag.
Following is a sample kubeconfig file from a minikube installation.
