Managing cluster and namespace in k8s sometime is quite complicated especially when you have to deal with multiples resources.
There is a great project called kubectx that makes your life easy.
kubectx helps you switch between clusters back and forth and kubens helps you switch between Kubernetes namespaces smoothly.
$ kubectx minikube Switched to context "minikube". $ kubectx - Switched to context "oregon". $ kubectx - Switched to context "minikube". $ kubectx dublin=gke_ahmetb_europe-west1-b_dublin Context "dublin" set. Aliased "gke_ahmetb_europe-west1-b_dublin" as "dublin".
