Network mode container in docker-compose

Question

With plain docker I can use network mode container like this:

docker run -d --name container-b --network container:container-a <image>

Can this be achieved using docker-compose?

services:
  service-b:
    container_name: container-b
    network_mode: "container:container-a"

Leads to:

ERROR: Please provide 'network_mode: "bridge"' or 'network_mode: "host"' in your docker-compose.yaml

Answer 1

I have a docker-compose file with version '2.1', but I am able to do this:

services:
  service-b:
    container_name: container-b
    network_mode: service:container-a

This makes all of my container-b traffic flow through container-a
