SIGPwny Note

Do not push sensitive config variables! Use a .env file in the root of the folder instead. See .env.example

SIGPwny Testing locally

• Run git submodule init && git submodule update
• Set DISCORD_WEBHOOK_URL= after you copy .env.example to .env.
• Turn off nginx SSL (copy this section to the docker-compose.yml)

  nginx:
    image: nginx:stable
    restart: always
    volumes:
      - ./conf/nginx/original-http.conf:/etc/nginx/nginx.conf
      # - ./conf/nginx/cert.pem:/etc/nginx/cert.pem
      # - ./conf/nginx/key.pem:/etc/nginx/key.pem
      # - ./sslkeys:/etc/ssl:ro
      # - ./logs:/etc/nginx/logs
    ports:
      - 80:80
      # - 443:443
    depends_on:
      - ctfd

Updating dependencies with Nix

This is incredibly scuffed, but basically poetry2nix will pull the package wheel from PyPI if it's specified in poetry.lock, and otherwise build using nixpkgs if it's not. Some packages refuse to build using nix, and some refuse to build using wheels. So the process is as follows:

1. List all dependencies from requirements.in in pyproject.toml and build using nix develop.
2. Try to fix any errors that arise using this guide, but if you can't fix it, comment out the package. Repeat until you build without errors.
3. Copy the old pyproject.toml somewhere and make a new pyproject.toml that only includes python and the problem packages, and run poetry lock.
4. Revert to the old pyproject.toml, and this time uncomment out all packages. Run nix develop.

Pulling new changes from main CTFd repo

Since our history has diverged from CTFd/CTFd, do not ever attempt a rebase from the upstream. Instead, you can try:

git remote add upstream https://github.com/CTFd/CTFd
git fetch upstream
git checkout master # our local branch
git merge upstream/master --strategy-option theirs # prefer their changes over ours
git push

Updating theme and plugins

git submodule update --remote --merge
git add CTFd # Make sure you don't commit your dev docker-compose.yml
git commit -m "Update submodules" && git push

Managed Hosting

Looking to use CTFd but don't want to deal with managing infrastructure? Check out the CTFd website for managed CTFd deployments.

MajorLeagueCyber

CTFd is heavily integrated with MajorLeagueCyber. MajorLeagueCyber (MLC) is a CTF stats tracker that provides event scheduling, team tracking, and single sign on for events.

By registering your CTF event with MajorLeagueCyber users can automatically login, track their individual and team scores, submit writeups, and get notifications of important events.

To integrate with MajorLeagueCyber, simply register an account, create an event, and install the client ID and client secret in the relevant portion in CTFd/config.py or in the admin panel:

OAUTH_CLIENT_ID = None
OAUTH_CLIENT_SECRET = None
