The official OpenShift documentation currently lacks coverage of the platform: external installation method, which is only described in https://docs.providers.openshift.org/platform-external/installing/. This method enables deployment of OpenShift on any custom or unsupported infrastructure by allowing users to bring their networking, compute, and storage.

A critical part of this deployment model is the use of a Cloud Controller Manager (CCM) to integrate platform-specific features like load balancer, node, and route management. The CCM must be manually deployed and configured, making clear and official guidance essential.

Why this matters:

• Enables cloud-agnostic OpenShift deployments for edge, on-prem, and hybrid environments.

• Lack of documentation creates confusion, increases misconfiguration risk, and impacts supportability.

• CCM is a mandatory component in platform: external setups and must be documented to ensure correct usage.

Request:
Include an officially supported section in the OpenShift documentation for platform: external installations, covering CCM deployment, network and infra prerequisites, install-config options, and best practices.
