After your clusters, users, and contexts are defined in one or more configuration files, you can quickly switch between clusters by using the kubectl config use-context command. Note: A file that is used to configure access to a cluster is sometimes called a kubeconfig file.
To start the minikube, type “minikube start” into the terminal. A virtual machine capable of running a single node cluster will be constructed, and the Kubernetes cluster will be launched. It also works with the kubectl setup.
What this says is that you can create or modify contexts in your kubeconfig file with the command kubectl config set-context. This command also accepts the name of the context to be changed (or --current if you want to change the current context), as well as --user, --cluster, and --namespace options.
You can switch from local (minikube) to gcloud and back with:
kubectl config use-context CONTEXT_NAME
to list all contexts:
kubectl config get-contexts
You can create different enviroments for local and gcloud and put it in separate yaml files.
A faster shortcut to the standard kubectl commands is to use kubectx:
kubectx
kubectl config get-contexts
kubectx foo
kubectl config use-context foo
To install on macOS: brew install kubectx
The kubectx package also includes a similar tool for switching namespaces called kubens.
These two are super convenient if you work in multiple contexts and namespaces regularly.

kubectl config get-contexts
kubectl config set current-context MY-CONTEXT
If you're looking for a GUI-based solution for Mac and have the Docker Desktop installed, you can use the Docker Menu Bar icon. Here you can find "Kubernetes" menu with all the contexts you have in your kubeconfig and easily switch between them.

A simple way to switch between kubectl context,
kubectl top nodes **--context=**context01name
kubectl top nodes --context=context02name
You can also store the context name as env like context01name=gke_${GOOGLE_CLOUD_PROJECT}_us-central1-a_standard-cluster-1
