Docker containers does not run any Katalon Tests but exits with return code 0

I am trying to execute 4 different test suites from the same Katalon Project on 4 different Docker containers.
I am building the docker containers using FROM katalonstudio/katalon:latest
In the docker container terminal I can see that it is using Katalon version 7.2.3.
I am using Ubuntu 18.04.

2 out of the 4 containers don’t execute the test suite at all while 2 others do execute the test suites.I am passing the test suite name as an argument to a shell script that is used as an ENTRYPOINT in the docker container.
It seems to stop working after loading the plugins for the containers that don’t execute the tests.
Here is an example of what I am seeing in the terminal for the container:

  • echo ‘Starting Katalon Studio’

  • exit 0

I need to understand what the root cause here could be. We are trying to run different test suites and eventually different test suite collections on different docker containers.
If tests cannot run on different containers at the same time for the same project then this is not going to work for me and my team.

Any help / insight would be highly appreciated.
