title: Right use of docker volume for node-red
body: <p>I'm currently working with node-red docker container. To install and keep additional nodes I re-use the existing image.</p>
  
  <p>Now I learned that the "right" way for persistence is to use docker volumes.</p>
  
  <p>What would be the right way to setup and use volumes for installing and keeping node-red nodes?</p>
