Summary

  • Adds an [IMPORTANT] admonition to configuring-cluster-network-range.adoc noting that expanding the service network CIDR post-installation is not supported, even though the upstream Kubernetes ServiceCIDR API is visible in OCP. The Cluster Network Operator blocks this via a ValidatingAdmissionPolicy.
  • Strengthens the existing post-install note in nw-operator-cr.adoc to explicitly call out that serviceNetwork is immutable and the ServiceCIDR API is blocked.

in the cluster and documented in the API reference, not just
"visible."
