kubectl set-context development --namespace=testing Need to repoint a context to a different cluster? You can do that without deleting and recreating it.

It does one small thing—modifying a field in a text file—but that small thing is the foundation of safe, efficient multi-cluster Kubernetes administration.

kubectl set-context production --cluster=aws-prod --user=admin-user This creates the context but does not switch to it. To switch, you would run kubectl use-context production . This is the most common real-world use case. You have a context called staging , but you are tired of typing -n backend for every command.

# Good: Relies on context namespace kubectl get pods kubectl get pods -n default 3. Verify Before You Execute Create a shell alias to show your current context in your prompt:
