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.
Choosing a method to install OKD on OpenStack
You can install OKD 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 OKD 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.
Installing a cluster on installer-provisioned infrastructure
You can install a cluster on Red Hat OpenStack Platform (RHOSP) infrastructure that is provisioned by the OKD installation program, by using one of the following methods:
Installing a cluster on OpenStack with customizations: You can install a customized cluster on RHOSP. The installation program allows for some customization to be applied at the installation stage. Many other customization options are available post-installation.
Installing a cluster on OpenStack with Kuryr: You can install a customized OKD cluster on RHOSP that uses Kuryr SDN. Kuryr and OKD integration is primarily designed for OKD clusters running on RHOSP VMs. Kuryr improves the network performance by plugging OKD pods into RHOSP SDN. In addition, it provides interconnectivity between pods and RHOSP virtual instances.
Installing a cluster on OpenStack in a restricted network: You can install OKD on RHOSP in a restricted or disconnected network by creating an internal mirror of the installation release content. You can use this method to install a 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.
Installing a cluster on user-provisioned infrastructure
You can install a cluster on RHOSP infrastructure that you provision, by using one of the following methods:
Installing a cluster on OpenStack on your own infrastructure: You can install OKD on user-provisioned RHOSP infrastructure. By using this installation method, you can integrate your cluster with existing infrastructure and modifications. For installations on user-provisioned infrastructure, you must create all RHOSP resources, like Nova servers, Neutron ports, and security groups. You can use the provided Ansible playbooks to assist with the deployment process.
Installing a cluster on OpenStack with Kuryr on your own infrastructure: You can install OKD on user-provisioned RHOSP infrastructure that uses Kuryr SDN.
Installing a cluster on OpenStack on your own SR-IOV infrastructure: You can install OKD on user-provisioned RHOSP infrastructure that uses single-root input/output virtualization (SR-IOV) networks to run compute machines.
