Docker migrations

Question

I am trying to run a rails application using docker and fig, it counts with the redis, mongodb, postgres and nginx server. Here is my fig.yml:

pg:
  image: docker-index.my.com/postgres
  ports:
    - 5432
redis:
  image: docker-index.my.com/redis
  ports:
    - 6379
mongodb:
  image: docker-index.my.com/mongodb
  ports:
    - 27017
app:
  build: .
  command: bundle exec rails s
  volumes:
    - .:/beesor
  ports:
    - 3000:3000
  links:
    - pg
    - redis
    - mongodb
  environment:
    RAILS_ENV: production

Everything works fine until the application is launched, since the rail initializers are launched on the server, then I received errors regarding the connection to the database, the database does not exist! of course, because it was not created in the Docker file (see below)
