You can install {product-title} with the link:https://access.redhat.com/documentation/en-us/assisted_installer_for_openshift_container_platform/2022/html-single/assisted_installer_for_openshift_container_platform/index[{ai-full}]. This method requires no setup for the installer, and is ideal for connected environments like {ibmzProductName}.
27

See xref:../../installing/installing_on_prem_assisted/installing-on-prem-assisted.adoc#installing-on-prem-assisted[Installing an on-premise cluster using the {ai-full}] for additional details.

Installing OpenShift Container Platform with the Assisted Installer on {ibmzProductName} is supported only with {op-system-base} KVM installations.

34

You can also install {product-title} 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.

====

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 {ibmzProductName} platform and the installation process of {product-title}. Use the user-provisioned infrastructure installation instructions as a guide; you are free to create the required resources through other methods.

=== User-provisioned infrastructure installation of {product-title} on {ibmzProductName}

User-provisioned infrastructure requires the user to provision all resources required by {product-title}.
