Kali Linux Penetration Testing Bible

APPENDIX BBuilding a Lab Environment Using Docker

In Appendix A, you learned how to install Kali from scratch using an ISO file. This kind of installation is typical for a production host where you install Kali to use it with real penetration testing engagements. This appendix focuses on the other side of the game; you will learn how to build a virtualized environment for testing and practicing using Docker. Also, you can build your lab environment using a hypervisor. But this appendix is dedicated to Docker since it's a new, trending versatile technology. Opening a VM is straightforward compared to the Docker containers.

Here we will delve deep with Docker, and you will see how images and containers work in practice. Both Docker and hypervisor technologies facilitate the creation of a live lab, so we, penetration testers, can have fun with it.

Docker containers are new to some people, so take advantage of this appendix to learn how it works by practicing the exercises. You will see a few practical scenarios to help you handle Docker containers. Don't worry, by the end of this appendix you will start using Docker like a pro.

In this appendix, you will learn about the following:

• Managing images in Docker
• Creating Docker containers
• Understanding Docker networks and volumes
• Practicing with a virtual Docker environment
