Prerequisites

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:
