ERROR: Named volume "xplore:/root/xPlore/rtdata:rw" is used in service "dsearch" but no declaration was found in the volumes section

Question

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.

Below is the single compose file :

  version: '2'

            external:

Answer 1

This error often appears when you are trying to create a volume as a subfolder of your current host folder. In that case, the syntax would have to be:

volumes:
    - ./centdb_odbc:/opt/dctm/odbc

In other words: The relative path "./" is missing!

Answer 2

When you map a directory, the source part must be either an absolute path, or a relative part that begins with ./ or ../. Otherwise, Docker interprets it as a Named Volume.

So instead of

volumes:
    - xplore:/root/xPlore/rtdata

You should write:

volumes:
    - ./xplore:/root/xPlore/rtdata
