Create and expose deployment using NodePort Service in Kubernetes

This is a practice question for Kubernetes CKA and CKAD exams.

Question
We have a 3 node cluster setup locally using kubeadm. We need to do the following:

• Create a deployment named web-deploy with the 3 replicas of image mycloudtutorials/poddeployservicedemo:latest in namespace app1
  (The Docker container is created from apache image, exposing the application on port 80)

• Pass the following environment variables NODE_NAME, POD_NAME, POD_IP which are the name of the node where the pod is running, name of the pod and the ip address of the pod respectively

• Verify the pods are working fine, by curl to the individual pods using POD’s internal ip address

• Create a service for this deployment of type NodePort with name web-service in namespace app1 on port 30090

• Check the End points

• Access the service on each of the node:port of the cluster nodes from outside of the cluster
