Hi team,

I am following below exercise
https://github.com/dgkanatsios/CKAD-exercises/blob/master/f.services.md#create-a-pod-with-image-nginx-called-nginx-and-expose-its-port-80

Question:
Create a pod with image nginx called nginx and expose its port 80

I am confused whether service needs to be created or not, as port I can export without creating the service also like,

kubectl run nginx --image=nginx --port=80

The second question after above expects that you would have created the clusterIP service using the below command:

kubectl run nginx --image=nginx --restart=Never --port=80 --expose

Please guide me how do I understand it is asking for creating the service also.
Thanks

Mohamed Ayman:
To expose the POD port, you need to create a service for the POD.

Mohamed Ayman:
–expose option will create the service for you.

@Mohamed Ayman Thanks for clarification. when you wrote it, I can clearly understand/recall the difference between container port and Pod port.
