How to switch namespace in kubernetes

Question

Say, I have two namespaces k8s-app1 and k8s-app2

I can list all pods from specific namespace using the below command

kubectl get pods -n 

        

Answer 1

A Solution

npm install -g k8ss

k8ss switch --namespace=your_namespace
kubectl get pods

TLDR; Explanation as requested

There is a npm package called k8ss which stands for K8S Switching between clusters and namespaces.

The full usage is

k8ss switch --cluster=your_new_cluster --namespace=your_new_namespace

As in your case, you only need to switch namespace, so you can use the command without any configuration (as you already put a config file in the ~/.kube/config).

Advanced Usage

If you need to switch between different clusters then you need to put multiple config files in your home directory. In this case you can go to the package README to learn more.
