Preparing to install on vSphere

Preparing to install on vSphere

Prerequisites

You reviewed details about the OKD installation and update processes.
You read the documentation on selecting a cluster installation method and preparing it for users.
If you use a firewall and plan to use Telemetry, you configured the firewall to allow the sites required by your cluster.

Choosing a method to install OKD on vSphere

You can install OKD on vSphere by using 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 OKD on infrastructure that you provide. If you do not use infrastructure that the installation program provisions, you must manage and maintain the cluster resources yourself.

See the Installation process for more information about installer-provisioned and user-provisioned installation processes.

The steps for performing a user-provisioned infrastructure installation are provided as an example only. Installing a cluster with infrastructure you provide requires knowledge of the vSphere platform and the installation process of OKD. Use the user-provisioned infrastructure installation instructions as a guide; you are free to create the required resources through other methods.

Installer-provisioned infrastructure installation of OKD on vSphere

Installer-provisioned infrastructure allows the installation program to pre-configure and automate the provisioning of resources required by OKD.

Installing a cluster on vSphere: You can install OKD on vSphere by using installer-provisioned infrastructure installation with no customization.
Installing a cluster on vSphere with customizations: You can install OKD on vSphere by using installer-provisioned infrastructure installation with the default customization options.
Installing a cluster on vSphere with network customizations: You can install OKD on installer-provisioned vSphere infrastructure, with network customizations. You can customize your OKD network configuration during installation, so that your cluster can coexist with your existing IP address allocations and adhere to your network requirements.
Installing a cluster on vSphere in a restricted network: You can install a cluster on VMware vSphere infrastructure in a restricted network by creating an internal mirror of the installation release content. You can use this method to deploy OKD on an internal network that is not visible to the internet.

User-provisioned infrastructure installation of OKD on vSphere

User-provisioned infrastructure requires the user to provision all resources required by OKD.

Installing a cluster on vSphere with user-provisioned infrastructure: You can install OKD on VMware vSphere infrastructure that you provision.
Installing a cluster on vSphere with network customizations with user-provisioned infrastructure: You can install OKD on VMware vSphere infrastructure that you provision with customized network configuration options.
Installing a cluster on vSphere in a restricted network with user-provisioned infrastructure: OKD can be installed on VMware vSphere infrastructure that you provision in a restricted network.

Uninstalling an installer-provisioned infrastructure installation of OKD on vSphere

Uninstalling a cluster on vSphere that uses installer-provisioned infrastructure: You can remove a cluster that you deployed on VMware vSphere infrastructure that used installer-provisioned infrastructure.
