Two Docker containers not communicating with each other

I've hosted OSRM server: https://hub.docker.com/r/osrm/osrm-backend/

docker run -t -i --network="test-net" -p 5000:5000 -v "${PWD}:/data" osrm/osrm-backend osrm-routed --algorithm mld /data/indonesia-latest.osrm

And its working as I am getting following output when browsing it: 

{"message":"URL string malformed close to position 1: \"\/\"","code":"InvalidUrl"}

The backend is made using Django and the following code is supposed to hit the OSRM server and give the response: 

BACKEND_HOST = os.getenv('WEB_VRP_BACKEND_HOST', '<ip address of osrm hosted server>')
BACKEND_PORT = os.getenv('WEB_VRP_BACKEND_PORT', '5000')

request = 'http://' + BACKEND_HOST + ':' + BACKEND_PORT + '/table/v1/driving/'

Both OSRM and Django is hosted in the same server and same network. The backend is built using docker and run

docker run --name vrp-backend --network="test-net" -d -p 9012:8090 vrp-web-django

And when i hit the backend with this address and required parameters, i get status:invalid in Postman. The two containers don't seem to be communicating but both are in same network and same server. 

http://<ip address>/vrp/parse

I created the test-net network which is bridged. And docker inspect also shows both container in same network. What could be the cause? Thanks

Have you considered using docker-compose? You would have an easier time building and running multiple containers with docker-compose build and docker-compose up. The yaml file can look something like this:

version: "2.2"
services:
  vrp-backend:
    restart: always
    build: path/to/dockerfile # or image: image_name:latest
    command: python3 manage.py runserver
    ports:
      - '9012:8090'
    links:
      - 'osrm:osrm'
  osrm:
    image: osrm/osrm-backend
    command: osrm-routed --algorithm mld /data/indonesia-latest.osrm

This will create a default network for you and will connect the containers to it.
