I am creating an OrientDB cluster with Kubernetes (in Minikube) and I use Stateful Sets to create pods. I am trying to mount all the OrientDB cluster configs into a folder named configs. Using command I copy the files after mounting into the standard /orientdb/config folder. However, after I have added this functionality the pods were created at a slower rate and sometimes I get exceptions like:

Unable to connect to the server: net/http: TLS handshake timeout

Before that, I tried to mount configs directly into the /orientdb/config folder. But I had an error with permissions so I have researched that mounting to the root folder is prohibited.

How can I approach such an issue? And can I find some workaround?

The Stateful Set looks like this:
