docker 1.12 swarm : Does Swarm have a configuration store like kubernetes configMap
<p>As per kubernetes docs: <a href="http://kubernetes.io/docs/user-guide/configmap/" rel="nofollow">http://kubernetes.io/docs/user-guide/configmap/</a></p>

<blockquote>
  <p>Kubernetes has a ConfigMap API resource which  holds key-value pairs
  of configuration data that can be consumed in pods.</p>
</blockquote>

<p>This looks like a very useful feature as many containers require configuration via some combination of config files,  and environment variables</p>

<p>Is there a similar feature in docker1.12 swarm ?</p>
