            - CTFPAD_USE_HTTPS=false
            - CTFPAD_PROXY_USE_HTTPS=false

            # default certificates are generated and put to
            # /data/{key,cert}.pem; change this if you e.g.
            # want to use let's encrypt certificates
            - CTFPAD_SSL_KEY_FILE=/data/key.pem
            - CTFPAD_SSL_CERT_FILE=/data/cert.pem

            # authentication key for new signups

            # etherpad proxy port
            - ETHERPAD_PORT=4343

            # this unless you really need to
            - ETHERPAD_INTERNAL_PORT=9001

            # it's strongly recommended to use mysql or 
            # mariadb for etherpad's data storage; 
            # set credentials here
            - MYSQL_HOST=
            - MYSQL_USER=
            - MYSQL_PASSWORD=

        volumes:
            - ./ctfpad_data:/data:z

If you want to change the ports CTFPad will listen on, make sure to both change the docker ports and the environment variables. Otherwise, at least the etherpad istance will not be reachable.

You need to remove and recreate the container if you want to change settings for a running instance if CTFPad. You can use the following snippet:

docker-compose stop ctfpad
docker-compose rm -f ctfpad
docker-compose up -d --no-deps ctfpad
