Experimental Attack/Defence CTF proxy.

Steps: Create a docker network to connect all the containers with the proxy:

docker network create bear-proxy_internal

Add all the containers in the same network appending

networks:
  internal:
    external:
      name: bear-proxy_internal

in their docker-compose.yml. Also, don't forget to modify their exposed port.

In the config.yml use the container name as hostname of the services to proxy. In the docker-compose.yml expose all the services ports.

Lastly, build and run the container:

docker compose up --build -d
