How to make docker container to use host network? - docker

Question

I am running docker for mac. My docker compose configuration file is:
version: "2.3"
services:
base:
build:
context: .
dev:
network_mode: "host"
extends:
service: base
when the container is launched via docker-compose run --rm dev sh, it can't ping a IP address (172.25.36.32). But I can ping this address from host. I have set network_mode: "host" on the configuration file. How can I make the docker container share host network?
I found that host network doesn't work for Mac. Is there a solution for that in Mac?
Below is the docker network inspect ID output:

Answer 1

i believe you need to add network option during the build. Try with
version: "2.3"
services:
base:
build:
context: .
network: host
dev:
network_mode: "host"
extends:
service: base
EDIT: Works on Linux, please see documentation for Mac
The host networking driver only works on Linux hosts, and is not supported on Docker Desktop for Mac, Docker Desktop for Windows, or Docker EE for Windows Server.

Answer 2

I think you need to start the container with up option not run since run override many options:
docker-compose up dev
or you may try with --use-aliases with run
--use-aliases Use the service's network aliases in the network(s) the
container connects to.
see this
P.S
After your update
the following will work on MAC
dev:
network: host
extends:
service: base
