title: Create volume with docker volume with a custom Mountpoint
body: <p>I need to create a volume with "docker volume" with a personal Mountpoint (mountpoint="/my/path/  not  /var/lib/docker...) but i can't use plugin like local-persist </p>
  
  <pre><code>docker volume create -d local-persist -o mountpoint=/data/images --name=images
  </code></pre>
  
  <p>i need something like this but without plugin, maybe it can be done with --opt= and somethig after that, but i'm new at docker and linux.
  I hope someone can help me, just pay attention: i need "docker volume create" not something that let me use personal path in docker-compose.yml or something like this.</p>
  
  <p>Edit</p>
  
  <p>my docker compose is something like</p>
  
  <pre><code>version: '3.1'
  
  services:
  
    grafana:
      image: grafana/grafana:5.3.4
      ports:
        - 3000:3000
      volumes:
        - grafanasql:/var/lib/grafana
        - grafanaconf:/etc/grafana
    ...
    ...
    volumes:
      grafanasql:
        external: true
      grafanaconf:
        external: true
  </code></pre>
  
  <p>If i let docker create volumes all its ok, but when i try to use external volume, with your docker volume create it doesnt work.</p>
