Issue when installing helmchart with rights in etc

[sbaloo]

I've got:

Permission denied: ../etc/broker.xml
Permission denied: ../etc/broker.xml
sed: couldn't open temporary file ../etc/sed1d0l85: Permission denied

when installing the chart and running the pod. I see that the user in dockerfile is fixed or my openshift when running pod use randomuser.

Do you thing i need to update the dockerfile to add :
RUN chgrp -R 0 /some/directory &&
chmod -R g=u /some/directory

or do you have other solution?
