Howto create Docker Network with Docker Compose - Communication between Services inside of a Container

Create your network named 'yournetwork':

$ docker network create -d bridge yournetwork

You have created your own network now.
Verify it by typing

$network inspect yournetwork:

In the docker-compose.yml:

networks:
  yournetwork: #TODO remove this hard-coded network reference
    external:
      name: ${NETWORK}

  yourservice:
  container_name: "your-container-name"
    image: your-image-name:${TAG:-latest} #will pull the latest                                                #tagged image of yours
    ports:
    - 8080:8080 #example localhost:8080
    net: ${NETWORK}

Start it with:

$ NETWORK=yournetwork docker-compose-up
