Installer-provisioned installation provides support for installing OKD on bare metal nodes. This guide provides a methodology to achieving a successful installation.

During installer-provisioned installation on bare metal, the installation program on the bare metal node labeled as provisioner creates a bootstrap virtual machine (VM). The role of the bootstrap VM is to assist in the process of deploying an OKD cluster. The bootstrap VM connects to the baremetal network and to the provisioning network, if present, via the network bridges.

Deployment phase one

The provisioning node can be removed after the installation.

When the installation of OKD is complete and fully operational, the installation program destroys the bootstrap VM automatically and moves the virtual IP addresses (VIPs) to the appropriate nodes accordingly. The API VIP moves to the control plane nodes and the Ingress VIP moves to the worker nodes.

Deployment phase two

The provisioning network is optional, but it is required for PXE booting. If you deploy without a provisioning network, you must use a virtual media BMC addressing option such as redfish-virtualmedia or idrac-virtualmedia.
