How to setup multiple separated oracle database dockers on same Host?-CodePudding

I want to setup and run multiple oracle database docker containers on the same host (Red Hat OS), each database will use a separated area on the host to store data. These docker containers use the same docker image. For example:

Container 1 will listen on port 1521 and store data in /home/user/oracle_data/container_1 folder on host.
Container 2 will listen on port 1522 and store data in /home/user/oracle_data/container_2 folder on host.
Container 3 will listen on port 1523 and store data in /home/user/oracle_data/container_3 folder on host.

Can you tell me the best practice to solve this task?

Thanks and best regards,

Inside every container keep using the default port of 1521. Remap this port to external world to your custom port.

Same thing with folders - keep the folders the same inside the container, remap them to different folders in the host

For example, if using docker-compose, for the first container use:

ports:
   1521:1521
volumes:
   /oracle/data1:/oracle/data

for the second container use:

ports:
   1522:1521
volumes:
   /oracle/data2:/oracle/data
