Setting up a Kali docker container for HackTheBox and other stuff.
You wanna practice and that pesky virtual image is too hard/tiresome/pesky to setup and run on your machine?
Well, what about a Kali Linux docker container that you can use all your tools from and also run GUI apps if you're so inclined?!
Step - 1: Download & Run the Kali Linux Docker image
Here's the official link and honestly it covers almost everything: Kali Linux Docker
Step - 2: Setup your Kali with meta-packages
Another great official link: Kali meta-packages
Step - 3: Allow VPN connections!
We all know how handy and important VPNs are. So adding the following command when running your docker container allows connections to pass through(also allowing ipv6):
--cap-add=NET_ADMIN --device /dev/net/tun --sysctl net.ipv6.conf.all.disable_ipv6=0
Step - 4: Allow GUI apps to access X server!
Install xhost package from your distribution package manager (mostly it's just named xorg-xhost)
and run the following command to allow remote hosts to connect to the X server before starting your docker container with:
xhost+
for the docker GUI X clients we need to add the following arguments to setup the X connection properly:
-e DISPLAY=:0 -v /tmp/.X11-unix:/tmp/.X11-unix
Tip: Remember to deny remote hosts after closing your docker container! ( just run xhost - for it)
Step - 5: Profit!
Here's the complete command:
xhost + &&\
docker run -ti --cap-add=NET_ADMIN --device /dev/net/tun \
--sysctl net.ipv6.conf.all.disable_ipv6=0 \
-e DISPLAY=:0 -v /tmp/.X11-unix:/tmp/.X11-unix \
YOUR_DOCKER_IMAGE_NAME /bin/bash && xhost -
Here's a link for a nifty little script that packages everything (My docker image is named kali_pt):
