Permission denied error for orientdb non root image on AKS volume mount disk

[akshay-mahakalkar]

OrientDB Version: 3.0.29
Issue type: Non-root docker image for OrientDB

Description:
I am trying to create a OrientDB non root image. Following is my docker file.

FROM orientdb:3.0.29
#Create a group and user
RUN addgroup --system inteliuser --gid 1000 && adduser --system inteliuser --ingroup inteliuser --uid 1000
#Change permissions 
RUN chmod -R ugo+rwx /orientdb /usr/local/openjdk-8/bin 
#Tell docker that all future commands should run as the respected user
USER inteliuser
CMD [ "server.sh" ]

This works fine in local docker but when I try to run this on AKS cluster with volume mount on PVC managed disk, volume gives permission deny error for creating OSystem database.
I tried to run this without volume mount and it worked correctly and was able to create databases. Not sure why it is giving error to volume mount.
I have also tried by placing command arguments to the kubernetes deployment template. So that I can get time to check permissions defined. Following output I got,

inteliuser@orientdbservice1-57bb96d69f-xchnf:/orientdb$ ls -l

I am not able to create a directory or a file in volume mounted folders. Whereas I am able to create files or directories in /orientdb dir.

Note: This volume mount works with normal root image.
