Reading default port information from a json file

[Akilan1999]

Ports json file

This file will help map internal ports inside a container to external ports inside a container. A common example would be the SSH port which is port 22 inside the docker container and is mapped to random TCP port outside container so that any external machines can directly connect into the container. The below representation mentions of where the ports.json file is located and also the format of that file.

|_ <Container name>
        |_ Dockerfile
        |_ description.txt 
        |_ ports.json  // The ports file
