Chapter 1. Preparing to install on {rh-virtualization-first}
1.1. Prerequisites
- You reviewed details about the OpenShift Container Platform installation and update processes.
- You have a supported combination of versions in the Support Matrix for OpenShift Container Platform on Red Hat Virtualization (RHV).
- You read the documentation on selecting a cluster installation method and preparing it for users.
1.2. Choosing a method to install OpenShift Container Platform on RHV
You can install OpenShift Container Platform on installer-provisioned or user-provisioned infrastructure. The default installation type uses installer-provisioned infrastructure, where the installation program provisions the underlying infrastructure for the cluster. You can also install OpenShift Container Platform on infrastructure that you provision. If you do not use infrastructure that the installation program provisions, you must manage and maintain the cluster resources yourself.
See Installation process for more information about installer-provisioned and user-provisioned installation processes.
1.2.1. Installing a cluster on installer-provisioned infrastructure
You can install a cluster on Red Hat Virtualization (RHV) virtual machines that are provisioned by the OpenShift Container Platform installation program, by using one of the following methods:
- Installing a cluster quickly on RHV: You can quickly install OpenShift Container Platform on RHV virtual machines that the OpenShift Container Platform installation program provisions.
- Installing a cluster on RHV with customizations: You can install a customized OpenShift Container Platform cluster on installer-provisioned guests on RHV. The installation program allows for some customization to be applied at the installation stage. Many other customization options are available post-installation.
1.2.2. Installing a cluster on user-provisioned infrastructure
You can install a cluster on RHV virtual machines that you provision, by using one of the following methods:
- Installing a cluster on RHV with user-provisioned infrastructure: You can install OpenShift Container Platform on RHV virtual machines that you provision. You can use the provided Ansible playbooks to assist with the installation.
- Installing a cluster on RHV in a restricted network: You can install OpenShift Container Platform on RHV in a restricted or disconnected network by creating an internal mirror of the installation release content. You can use this method to install a user-provisioned cluster that does not require an active internet connection to obtain the software components. You can also use this installation method to ensure that your clusters only use container images that satisfy your organizational controls on external content.
