Docker-Compose yml file is not linking


(Kycalica) #1

Hi Guys,

I am new to using docker and so I have a bunch of questions but I’ll start off with this one:

version: '2'
services:
 web:
  build: .
  volumes:
    - .:/usr/app/src
  command: python /usr/app/src/dashboard/runserver.py
  ports:
    - "5000:5000"
  links:
   - postgres
   - rabbitmq
 postgres:
  image: postgres
 rabbitmq:
  image: rabbitmq

The problem is that my /etc/hosts file is changed and no env variables are placed to reference postgres or rabbitmq from my web container.

Anyone knows if this is a bug? I commented on a close issue in github where some people were still having problems, but it was not clear if those problems were solved or not.
