Define a non-root user?

[bilderbuchi]

I have played around with the openmodelica/openmodelica:v1.21.0-ompython Docker image -- quite useful!

One thing I found curious is that these images have not defined & used a non-root user, like you can find e.g. here.

This leads to the problem that even basic OMPython usage is not possible because omc does not like being run as root, e.g. doing docker run -it openmodelica/openmodelica:v1.21.0-ompython:

root@cc828498295a:~# python3 -c "from OMPython import OMCSessionZMQ;omc = OMCSessionZMQ()"
2023-08-10 11:43:25,730 - OMPython - ERROR - OMC Server did not start. Please start it! Log-file says:
Error: You are trying to run OpenModelica as a server using the root user.
This is a very bad idea:
* The socket interface does not authenticate the user.
* OpenModelica allows execution of arbitrary commands.
Execution failed!

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/local/lib/python3.10/dist-packages/OMPython/__init__.py", line 707, in __init__

Is that intentional/should that be changed?
