kubernetes: How to set active namespace for all kubectl commands?

Question

I am working on kubernetes cluster. In my cluster i am having 3 namespaces.

• Default

• Staging

• Production

At a time when i want to work on staging namespace.

In every kubectl command i have to pass namespace

kubectl get pods -n staging

kubectl get deployment -n staging

Is there any way to set active namespace at a time?

kubectl config set-context --current --namespace=<insert-namespace-name-here>
