Other Installation Methods

These are alternative installation methods for specific use cases:

• VMware vSphere IPI — Installer-Provisioned Infrastructure on VMware vSphere
• OpenShift on OpenShift (Hosted Control Planes) — Nested clusters with control planes running as pods
• Fleet Management — Multi-cluster management with ACM, including hub install and bare metal provisioning

Disconnected environments

Disconnected install is a two-step process. Set up a registry, then point OpenShift at it:

1. Set up the registry (choose one): - Mirror Registry (oc-mirror) — fully air-gapped - Pull-Through Cache — Artifactory or Nexus with outbound access
2. Configure OpenShift — install-config.yaml, catalog sources, and operators

For the primary POC installation methods, see the Installation Overview.
