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

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'

dsearch:

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

Answer 3

Volumes Command should be the last command in docker compose include volume names of all services together and run the docker compose. It will create containers.
volumes:
xplore: {}
centdb_data:
driver: local
centdb_dba:
centdb_share:
