host.docker.internal on Linux

On Linux, we can't automatically resolve host.docker.internal, we need to provide some arguments to the docker run command

--add-host=host.docker.internal:host-gateway

Where host-gateway is the IP address of the docker daemon.

To find out what's the ip address of our docker daemon, we have to check out the interface associated to it, via ifconfig -a (that should be named docker0 as well)
