title: Find IP address of docker container running inside docker swarm
body: <p>I have a docker swarm cluster.  I deployed a Elassandra docker image.  Now I want to find that the docker container's IP address for the seed node:</p>
  
  <p>The following are my services in my swarm:</p>
  
  <blockquote>
    <p>docker service ls</p>
    
    <p>ID                  NAME<br>
    yjehoql7l976       elassandra_seed</p>
  </blockquote>
  
  <p>I want find the IP address of the container for the Elassandra_seed node by its name to be used in my other docker compose file.  Is that possible? </p>
