title: create a Docker Swarm v1.12.3 service and mount a NFS volume
body: <p>I'm unable to get a NFS volume mounted for a Docker Swarm, and the lack of proper official documentation regarding the --mount syntax (<a href="https://docs.docker.com/engine/reference/commandline/service_create/" rel="noreferrer">https://docs.docker.com/engine/reference/commandline/service_create/</a>) doesnt help.</p>
  
  <p>I have tried basically this command line to create a simple nginx service with a /kkk directory mounted to an NFS volume:</p>
  
  <p>docker service create --mount type=volume,src=vol_name,volume-driver=local,dst=/kkk,volume-opt=type=nfs,volume-opt=device=192.168.1.1:/your/nfs/path --name test nginx</p>
  
  <p>The command line is accepted and the service is scheduled by Swarm, but the container never reaches "running" state and swarm tries to start a new instance every few seconds. I set the daemon to debug but no error regarding the volume shows...</p>
  
  <p>Which is the right syntax to create a service with a NFS volume?</p>
  
  <p>Thanks a lot</p>
