How “Docker” can help you become a better hacker

Intro

Recently I’ve seen the question pop up a lot: Do you use your native operating system for hacking or a VM? The answer might surprise you, dear hacker, I use neither. What I use are containers.

What is docker?

Docker enables you to separate your applications from your infrastructures. It consists of a daemon that manages several components of the Docker ecosystem. This consists of:

• Network components
• Containers
• Images
• Data volumes for storage

The daemon manages these components via a REST API. We can use a docker client to communicate with the daemon, which does all the heavy lifting for us. Keen-eyed readers might notice that this resembles a client-server architecture and they would be right, that’s exactly what docker is trying to implement.

The Docker client and daemon CAN run on the same server but they don’t have to.
