Operate shows AccessDeniedException on startup

With the latest release 8.3.0 Operate shows an AccessDeniedException on startup.

It seems to me the cause of this originates from the ownership/permission setup of /usr/local/operate folder in the original docker image. The folder is owned by root, but Operate is run with a non-root user, blocking it from creating the dir. Can you confirm @jessesimpson36 ? I think you already identified that during our pairing on the helm chart last Friday?

Then we would need to fix that in the Dockerfile of Operate.

Just reproduced the error and yeah I think the operate Dockerfile needs to be updated. Theres a temporary fix I can do in the compose file, I think. I'll try to take a look at it tomorrow.

Fixed in #368, so I'm closing this issue.
