12.6. Installing a cluster on vSphere in a restricted network
In OpenShift Container Platform 4.5, you can install a cluster on VMware vSphere infrastructure in a restricted network by creating an internal mirror of the installation release content.
12.6.1. Prerequisites
Create a registry on your mirror host and obtain the
imageContentSourcesdata for your version of OpenShift Container Platform.重要Because the installation media is on the mirror host, you can use that computer to complete all installation steps.
- Provision persistent storage for your cluster. To deploy a private image registry, your storage must provide the ReadWriteMany access mode.
- Review details about the OpenShift Container Platform installation and update processes.
If you use a firewall and plan to use telemetry, you must configure the firewall to allow the sites that your cluster requires access to.
注記If you are configuring a proxy, be sure to also review this site list.
