Mirror Registry for OpenShift doesn’t show correct IP address in logs

Issue

• When deploying Mirror Registry(on RHEL 8,9) as a non-root user, the real IP address of the local machine/ VM/ RHOCP worker nodes does not get logged.

• User logs from Quay WebUI, record the IP 10.0.2.100 even if requests to Quay come from different clients.

• Systemd logs show the below error message :

• How to log the real IP address of the client which is pulling images from the mirror registry?

• What is the right way to add a flag --network slirp4netns:port_handler=slirp4netns in the unit file quay-app.service?
