Hello everyone! I want to create a Swarm cluster with three nodes and one shared volume (in windows 10). I use docker-machine for it:
docker-machine create -d virtualbox swarm1-mgr1
docker-machine create -d virtualbox swarm1-wrk1
docker-machine create -d virtualbox swarm1-wrk2
Next I initialize a manager node:
docker-machine ssh swarm1-mgr1 docker swarm init
And add workers:
docker-machine ssh swarm1-wrk1 docker swarm join --token ...
docker-machine ssh swarm1-wrk2 docker swarm join --token ...
Next I configurate my console to work with the manager node:
docker-machine ssh swarm1-mgr1 "docker node ls"
docker-machine env swarm-mgr1
& "C:\ProgramData\chocolatey\lib\docker-machine\bin\docker-machine.exe" env swarm-mgr1 | Invoke-Expression
Then I created a register:
docker service create --name registry --publish 5006:5000 registry:2
docker-compose build
docker push localhost:5006/web
And finally I am trying to deploy my app:
docker stack deploy -c docker-compose.yml stack_1
docker service ps stack_1_web --no-trunc
But getting the next error messages:

I don’t understand why Swarm does not see my volume. Any help will be appreciated. My end goal is deploy stack on three nodes with one shared volume.
