This one needs environment variables set before it will start: CTFD_BASE_URL (Root URL of the CTFd v3 instance, e.g. https://ctf.example.com (without /api/v1)), CTFD_ADMIN_TOKEN (CTFd API access token (preferred authentication method)), CTFD_SESSION_COOKIE (Full CTFd session cookie, e.g. session=abc...), CTFD_USERNAME (Username for CTFd form login), CTFD_PASSWORD (Password for CTFd form login), CTFD_HTTP_TIMEOUT (Per-request HTTP timeout in seconds (default 15)). The author declared them in the registry entry; get the values from the project itself.
