Proxy is not allowing service to start

[dyatlov]

When I run docker-compose up:

MBP-Vitaly:bb dyatlov$ docker-compose up
Starting bb_db_1...
Starting bb_web_1...
Cannot start container 473e51676f19ffa3e15245d6bc1ffb0e73b04b405ede41b9bcad1c7134ff8773: Bind for 0.0.0.0:80 failed: port is already allocated

My docker-compose.yml:

db:
  image: postgres
web:
  build: .
  command: bundle exec foreman start -f Procfile
  volumes:
    - .:/app
  ports:
    - "80:3000"
    - "8030:8030"
  links:
    - db
  environment:
    - VIRTUAL_HOST=bb.dev

Procfile:

rails: rails s -p 3000 -b '0.0.0.0'
webpack: npm start

The dinghy up command has a flag to disable the proxy, if you need to.
