title: What is opposite of docker swarm init?
body: <p>With a single host with a swarm that has been created with init, the host gets networks created etc.</p>
  
  <p>There appears to be no 'docker swarm destroy' or similar that purges the system back to a state before the swarm.  I did a leave --force but that left networks.</p>
  
  <p>Do you have to manually tidy up a bunch of things you don't know were created or is there an easy command to get back to a clean setup?</p>
  
  <p>Thanks</p>
