Exercise 6:

• Create a namespace called dev
• Copy the list of the current namespaces inside the cluster in the file /home/cloud_user/namespace.txt
• Find the Pod namespace quark and check in which namespace the pod is in it, then save the name of this namespace on the file /home/cloud_user/quark-namespace.txt

Solution:

kubectl get nodes

kubectl get namespaces

kubectl create namespace dev

kubectl get namespaces

kubectl get namespace > /home/cloud_user/namespaces.txt

cat namespaces.txt

kubectl get pods --all-namespaces

nano /home/cloud_user/quark-namespace.txt
