toc::[]

In {product-title} version {product-version}, you can install a cluster on
{rh-openstack-first} that runs on user-provisioned infrastructure.

Using your own infrastructure allows you to integrate your cluster with existing infrastructure and modifications. The process requires more labor on your part than installer-provisioned installations, because you must create all {rh-openstack} resources, like Nova servers, Neutron ports, and security groups. However, Red Hat provides Ansible playbooks to help you in the deployment process.

== Prerequisites

* You reviewed details about the xref:../../architecture/architecture-installation.adoc#architecture-installation[{product-title} installation and update] processes.
* You read the documentation on xref:../../installing/overview/installing-preparing.adoc#installing-preparing[selecting a cluster installation method and preparing it for users].
* You verified that {product-title} {product-version} is compatible with your {rh-openstack} version by using the xref:../../architecture/architecture-installation.adoc#supported-platforms-for-openshift-clusters_architecture-installation[Supported platforms for OpenShift clusters] section. You can also compare platform support across different versions by viewing the link:https://access.redhat.com/articles/4679401[{product-title} on {rh-openstack} support matrix].
* You have an {rh-openstack} account where you want to install {product-title}.
* You understand performance and scalability practices for cluster scaling, control plane sizing, and etcd. For more information, see xref:../../scalability_and_performance/recommended-performance-scale-practices/recommended-control-plane-practices.adoc#recommended-host-practices[Recommended practices for scaling the cluster].
* On the machine from which you run the installation program, you have:
** A single directory in which you can keep the files you create during the installation process
** Python 3

[TIP]
====
You can add additional networks, including provider networks, to the `platform.openstack.additionalNetworkIDs` list.

After you deploy your cluster, you can attach pods to additional networks. For more information, see xref:../../networking/multiple_networks/understanding-multiple-networks.adoc#understanding-multiple-networks[Understanding multiple networks].
