Katana Docker Image

Building

$ docker build -t katana .

NOTE - The build process takes 5-10 minutes on our development machines. There are a lot of dependencies to to install and/or build. Be patient.

Running Katana

The default command for the docker image is:

python -m katana -c /data/katana.ini -m \
	monitor=/data/targets,outdir=/data/results

We recommend running Katana with the following command:

$ docker run -v "$(CTF_DIRECTORY):/data" -it katana

Where CTF_DIRECTORY is a directory with a configuration file and a targets directory. After Katana is started, it will automatically monitor the targets directory for targets to queue or you can manually queue targets as normal at the REPL.

The smallest configuration file you can use could be katana.ini like so:

[manager]
flag-format=FLAG{.*?}

Issues

The things that do not work when using the Docker container:

• Clipboard

  When Katana finds a flag, it will not be able to have it automatically copied into your clipboard.

• Notifications

  When Katana finds a flag, it will not be able to send you a desktop notification explaining that it solved a challenge.
