Unable to bind to bridge network gateway on OSX

Docker Desktop
1

Expected behavior

I should be able to bind a service to the gateway address of a virtual network. This works on docker-engine in Linux, but not on OSX.

Actual behavior

When binding to a gateway address, docker-compose up returns the error Unix.Unix_error(Unix.EADDRNOTAVAIL, "bind", "").

Information

I can bind any service to 0.0.0.0, but when I try to bind to the more restrictive network, Docker errors with Unix.EDDRNOTAVAIL.

Steps to reproduce the behavior

Using the following simple docker-compose yml on OSX will reproduce this:

version: '2'
networks:
  some-network:
    driver: bridge
    driver_opts:
      com.docker.network.bridge.host_binding_ipv4: "172.20.0.1"
    ipam:
      driver: default
      config:
      - subnet: 172.20.0.0/16
        gateway: 172.20.0.1
services:
  redis:
    image: redis:3
    ports:
      - 6379:6379
    restart: on-failure
    networks:
      some-network:
        ipv4_address: 172.20.0.102

$ docker-compose up

I’m running into this issue as well, would love to know if there are any work arounds.

With the latest Docker for OSX (Version 1.12.0-rc3-beta18 (build: 9969) 5cbabb0783b6d281b8f579cb9f4dff38373b2c10) this is still failing but the message has changed a little:

$ docker-compose up

Is there any update on a better way to run this compose file?
