Installing a cluster on vSphere in a restricted network

In {product-title} {product-version}, you can install a cluster on VMware vSphere infrastructure in a restricted network by creating an internal mirror of the installation release content.

Prerequisites

You have completed the tasks in Preparing to install a cluster using installer-provisioned infrastructure.
You reviewed your VMware platform licenses. Red Hat does not place any restrictions on your VMware licenses, but some VMware infrastructure components require licensing.
You reviewed details about the {product-title} installation and update processes.
You read the documentation on selecting a cluster installation method and preparing it for users.
You created a registry on your mirror host and obtained the imageContentSources data for your version of {product-title}.

Important

Because the installation media is on the mirror host, you can use that computer to complete all installation steps.
You provisioned persistent storage for your cluster. To deploy a private image registry, your storage must provide the ReadWriteMany access mode.
The {product-title} installer requires access to port 443 on the vCenter and ESXi hosts. You verified that port 443 is accessible.
If you use a firewall, you confirmed with the administrator that port 443 is accessible. Control plane nodes must be able to reach vCenter and ESXi hosts on port 443 for the installation to succeed.
If you use a firewall and plan to use the Telemetry service, you configured the firewall to allow the sites that your cluster requires access to.
