Basic Analysis of Docker Networking

Samyukta S Hegde, Jayarekha P

Abstract


Containerization is virtualization at operating system level as opposed to full machine virtualization. Docker is a tool that is used to create, ship and run applications inside containers. A single host can have multiple containers running on it. The containers may have to communicate with each other and by using docker networking, this can be accomplished. In this paper we explore docker networking and analyze how it is based on the concept of linux network namespaces. We will use Cisco Packet Tracer to implement a sample network. Then the same network will be implemented in Linux using ip tool. The same network will then be implemented using docker and the relationship between network namespaces and docker networking will be established.
