How I create new namespace in Kubernetes

Question

I work in a multi-tenant node app, I know to create a new namespace in Kubernetes is possible to run a kubectl command as follow: kubectl create namespace

Answer 1

you can create namespace using below command:

kubectl create namespace << namespace_name>>.

Please find below some examples

kubectl create namespace dev 
kubectl create namespace test
kubectl create namespace prod

To see namespace created:

kubectl get namespace   
     or  
kubectl get ns
     or 
kubectl get namespaces 

To avoid mentioning namespace in every kubectl command execution like while creating pod,deployment or any other kubernetes object, set namespace like as mentioned below:

kubectl config set-context --current --namespace=test

I hope this helped!!
