$ kubectl get namespace

Step 3: Create Namespaces - development, production

$ kubectl create namespace development
$ kubectl create namespace production

Step 4: Deploy and Inspect pods in development namespace

$ kubectl run nginx --image=nginx --namespace=development

$ kubectl get pods --namespace=development


Step 5: Deploy and Inspect pods in "production" namespace

$ kubectl run nginx --image=nginx --namespace=production --dry-run=client -o yaml

Copy the content and create a file: pod_ns_prod.yaml


$ vim pod_ns_prod.yaml

apiVersion: v1
kind: Pod
metadata:
labels:
run: nginx
name: nginx
namespace: production
spec:
containers:
- image: nginx
