title: How can I update the latest image that my docker service/stack uses?
body: <p>In the <code>.yml</code> definition, I'm always pulling the <code>latest</code> image of my service.</p>
  
  <p>When I push a new image to the registry and I want to update the image that the service in my stack uses. I don't see any <code>--pull</code> flag, and the documentation for <a href="https://docs.docker.com/engine/reference/commandline/service_update/" rel="noreferrer">docker service update</a> doesn't explicitly mentions this.</p>
  
  <p>How can I re-deploy using the recently pushed <code>latest</code> image?</p>
