Background

A customer using Technical Preview of Hosted Control Plane (HCP) found that the current documentation does not show complete ingress/egress rules. The ACM 2.15 documentation only shows kubelet ports but not other special ports required for HCP operation.

Problem Statement

The current documentation is incomplete and may cause customer confusion or connectivity issues when setting up firewall rules for HCP deployments.

Ports Identified for Investigation

The following ports have been identified by team members as potentially requiring documentation:

Ingress Ports

Egress Ports

Acceptance Criteria

• Investigate and verify the complete list of required ingress ports for HCP
• Investigate and verify the complete list of required egress ports for HCP
• Identify any platform-specific port requirements (AWS, Azure, Agent, KubeVirt, etc.)
• Document the purpose of each port and which component uses it
• Identify the target documentation location (ACM docs, OpenShift docs, or HyperShift repo docs)
• Create or update documentation with the verified port list
• Ensure documentation covers all supported HCP platforms
