NiFi Container Permissions

avatar
New Contributor

Hello,
We are trying to run NiFi + Registry 2.0.0-M2 on OpenShift, and no matter what combination of USER, chgrp, chmod, etc. we use we still get

"sed: couldn't open temporary file /opt/nifi/nifi-current/conf/sedYird4M: Permission denied"

and pod fails to start. 

We followed the OpenShift guidance of adding this to Dockerfile to no avail:
RUN chgrp -R 0 /opt/nifi && chmod -R g=u /opt/nifi

Please advise, this has been a blocker for a few days now!
