The lighter, leaner, meaner ctfbox, without all the crap
Pull the image from dockerhub using
docker pull epadctf/ctfbox
or build it yourself
git clone https://github.com/epadctf/ctfbox.git
cd ctfbox
docker build -t epadctf/ctfbox .
Start the image
docker run -it epadctf/ctfbox
If you have problems with gdb or gdbserver you can run the container in privileged mode and with the host network.
sudo docker run -it --rm --privileged --net=host -v $(pwd):/root/ctf epadctf/ctfbox
