如何从docker容器中获取mac主机IP地址？

Question

I want to access host IP address from a docker container on mac. I know how to do that on Linux by using the bridge0 interface. But docker for mac doesn't have bridge0. I tried to use the gateway 172.17.0.1 in a docker container but it doesn't work.

My docker for mac version is Docker version 1.13.0, build 49bf474 .

I looked at this link https://github.com/docker/docker/issues/22753 but it mentions to create an alias on lo0 interface which I don't want to. Because our project is running inside docker container and I want to provides a general way without changing anything on the host.

Does anyone know how to do that in Mac?

Answer 1

From the Docker documentation :

I WANT TO CONNECT FROM A CONTAINER TO A SERVICE ON THE HOST

The Mac has a changing IP address (or none if you have no network access). From 17.06 onwards our recommendation is to connect to the special Mac-only DNS name docker.for.mac.localhost which will resolve to the internal IP address used by the host.

I think you'll need to upgrade your Docker For Mac version for this to work.
