Run kubernetes on specific cluster or context

First list the context:
kubectl config get-contexts
Then either switch to a context:
kubectl config use-context $CONTEXT_NAME
Or simply run each command using the --context flag. For example to list the pods in a specific cluster run:
kubectl --context $CONTEXT_NAME get pods
To avoid verbosity, create functions in ~/.profile:
kubetest() {
    kubectl --context=$TEST_CONTEXT_NAME $@
}

kubeprod() {
    kubectl --context=$PROD_CONTEXT_NAME $@
}
