URLs to allow for mirroring registry to install OCP 4 in restricted network

Solution Verified - Updated -


  • When creating a mirror registry for OCP 4.x installation in a restricted network, which registry URLs needs to be whitelisted when the mirror registry host is behind the Firewall/Proxy ?
  • I am working in a disconnected/air-gapped environment. I have the mirror registry tested.
  • However for customers with a proxy between the mirror registry linux server and quay, what special settings must be made within the OCP side of configuration to address the registry?
