How are the docker port and Service and Pod ports related

Hi @RahulRege,

When in doubt, it always helps to check the documentation

The pod is a wrapper around one or many containers and it creates a network namespace for its container(s) to share.

A pod created with a container is not exposed to the outside world. It is only accessible from the local node so you won't find a port on the local node, but you will be able to access your containerized application thru the pod's IP address.

As opposed to a single container exposed to the outside world thru a random high-port of the local node, a pod is exposed thru another Kubernetes resource - a Service. Specific types of services receive a random high-port on every node in the Kubernetes cluster (the same high-port number reserved on every node), allowing access to a single pod from any node in the cluster and from the outside world.
