Run docker swarm mode on windows 10 using multiple hosts

I'm running Windows 10 with the latest updates installed. I'm trying to set up a swarm using multiple physical hosts running docker Linux containers on windows host. When I'm running

docker swarm init --advertise-addr 10.154.26.150 --listen-addr 10.154.26.150:2377

Where

10.154.26.150

stands for physical address of my current machine (future swarm manager) I obviously receive

Error response from daemon:
manager stopped:
failed to listen on remote API address: listen tcp 10.154.26.150:2377 
bind: cannot assign requested address

because docker for Windows running Linux containers uses hyper-v vm and doesn't know anything about address I'm trying to specify. So here is a question if there is any small possibility to run swarm mode in this situation so that my other hosts will be able to join new swarm over physical network.

If you're using "Docker for Windows", which runs a Moby VM in Hyper-V and simulates localhost, then it's easy for a single node Swarm setup. It's not yet designed to easily join outside machines.

If you want to have a 3-node swarm to spread out your testing, where they all have easy direct access to each other, then I recommend using docker-machine to create 3 more VM's in Hyper-V running boot2docker, like so:

docker-machine create --driver hyperv --hyperv-virtual-switch "Primary Virtual Switch" node1
docker-machine create --driver hyperv --hyperv-virtual-switch "Primary Virtual Switch" node2
docker-machine create --driver hyperv --hyperv-virtual-switch "Primary Virtual Switch" node3

NOTE: For this to work, 1. Be sure you're in PowerShell admin mode so docker-machine can control Hyper-V and 2. You'll need to create an "external" Hyper-V Switch and use its name in creating the VM's.

Details on the switch setup, and other options like changing CPU and memory are in the docker-machine docs.

Then you can change your docker CLI to control each one directly with & docker-machine env nodeX | Invoke-Expression and ssh into them with docker-machine ssh nodeX etc.

I use this setup and it works great!
