title: How can I save a docker plugin to file so that I can install it on a machine without internet
body: <p>I am using Docker to deploy my application as Docker containers.</p>
  <p>In one of the containers I use a volume that uses the vieux/sshfs plugin.<br />
  I can install and use the plugin using<br />
  <code>docker plugin install vieux/sshfs</code><br />
  on a computer that has access to the internet.</p>
  <p>However, I am deploying the container to a computer on a closed network.
  On that computer it is not possible to access docker hub as required by this command.
  I am therefore looking for a way to save the plugin to a file, transfer the file to the target computer and install it on that computer from the file.</p>
  <p>I use a similar approach for images.
  I save them on one computer and load them from file on the target.</p>
  <p>Is there any way to do the same for plugins?</p>
  <p>If not, is there another method which will enable me to install Docker plugins without access to the internet?</p>
