Create a new nginx Ingress resource as follows:
* Name: ping
* Namespace: ing-internal
* Exposing service hi on path /hi using service port 5678
Create a new NetworkPolicy named allow-port-from-namespace in the existing namespace echo. Ensure that the new NetworkPolicy allows Pods in namespace my-app to connect to port 9000 of Pods in namespace echo.
Further ensure that the new NetworkPolicy:
* does not allow access to Pods, which don't listen on port 9000
* does not allow access from Pods, which are not in namespace my-app
Given an existing Kubernetes cluster running version 1.20.0, upgrade all of the Kubernetes control plane and node components on the master node only to version 1.20.1.
Be sure to drain the master node before upgrading it and uncordon it after the upgrade.
You are also expected to upgrade kubelet and kubectl on the master node.
Set the node named ek8s-node-1 as unavailable and reschedule all the pods running on it.
List the nginx pod with custom columns POD_NAME and POD_STATUS
