5.3. Installing a cluster on bare metal in a restricted network
In OpenShift Container Platform version 4.5, you can install a cluster on bare metal infrastructure that you provision in a restricted network.
While you might be able to follow this procedure to deploy a cluster on virtualized or cloud environments, you must be aware of additional considerations for non-bare metal platforms. Review the information in the guidelines for deploying OpenShift Container Platform on non-tested platforms before you attempt to install an OpenShift Container Platform cluster in such an environment.
5.3.1. 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 ReadWriteMany access modes.
- 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.
