## Networking features for Mac and Linux

### SSH agent forwarding

Docker Desktop for Mac and Linux lets you use the host’s SSH agent inside a container. To do this:

1. Bind mount the SSH agent socket by adding the following parameter to your `docker run` command:

   ```console
   $--mount type=bind,src=/run/host-services/ssh-auth.sock,target=/run/host-services/ssh-auth.sock
   ```

2. Add the `SSH_AUTH_SOCK` environment variable in your container:

    ```console
    $ -e SSH_AUTH_SOCK="/run/host-services/ssh-auth.sock"
    ```

To enable the SSH agent in Docker Compose, add the following flags to your service:

 ```yaml
services:
  web:
    image: nginx:alpine
    volumes:
      - type: bind
        source: /run/host-services/ssh-auth.sock
        target: /run/host-services/ssh-auth.sock
    environment:
      - SSH_AUTH_SOCK=/run/host-services/ssh-auth.sock
 ```

## Known limitations

### Changing internal IP addresses

The internal IP addresses used by Docker can be changed from **Settings**. After changing IPs, you need to reset the Kubernetes cluster and to leave any active Swarm.

### There is no `docker0` bridge on the host

Because of the way networking is implemented in Docker Desktop, you cannot
see a `docker0` interface on the host. This interface is actually within the
virtual machine.

### I cannot ping my containers

Docker Desktop can't route traffic to Linux containers. However if you're a Windows user, you can
ping the Windows containers.

### Per-container IP addressing is not possible

This is because the Docker `bridge` network is not reachable from the host.
However if you are a Windows user, per-container IP addressing is possible with Windows containers.
