title: How to query --log-opt settings on a running container or service?
body: <p>I've used <code>docker service update my_service --log-opt mode=non-blocking</code> to change the logging options on a running service.  </p>
  
  <p>However, is there a way to then query the service (or its containers) to find out what <code>--log-opt</code> options are active?</p>
  
  <p><code>docker service inspect</code> or <code>docker container inspect</code> don't seem to have this information.</p>
