title: ERROR: Named volume "xplore:/root/xPlore/rtdata:rw" is used in service "dsearch" but no declaration was found in the volumes section
body: <p>I wanted to create containers for tomcat, documentum content server and documentum xplore by using a single compose file. Am facing issues due to the volumes mentioned in the docker-compose.yml file. Am able to bring up the services by executing the compose files separately. Problem is when i try to merge the compose files together. Wanted to know how to run multiple containers with volumes using docker compose. </p>
  
  <p>Below is the single compose file :</p>
