I was playing around with Docker for the past few days and really think that it is an awesome tool. I installed Docker for Mac and created an image based on the original Kali docker base image. I no longer need to spawn a full-fledged virtualbox VM running Kali just to run tools such as msfconsole, wpscan etc.
I created a Dockerfile project to automatically provision a base image which contains the tools that I require. This file can be tweaked to add/remove tools to your liking, and it is available here: https://github.com/v00d00sec/kali-minimal-dockerfile. If you just want to pull the full image without building it from scratch via the Dockerfile, you can pull the image from: https://hub.docker.com/r/v00d00sec/kali_mini/ by issuing the following commands:
docker pull v00d00sec/kali_mini
After-which, you can run the image like this:
Voila! Instant Kali shell spawned.
