Question

I\'ve been following with the docker-compose tutorial here (linking django and postgres container). Although I was able to go through with the tutorial I\'m however not able

Answer 1

you don't need to worry about environment variable. When linking containers together you just use the container alias defined by the link as if it was the hostname.

for instance if your docker-compose.yml file were:

db:
  image: postgres
web:
  build: .
  command: python manage.py runserver 0.0.0.0:8000
  volumes:
    - .:/code
  ports:
    - "8000:8000"
  links:
    - db:mydb

In your django settings you would have to set the database host to mydb.
