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

During installer-provisioned installation on bare metal, the installer 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 OpenShift Container Platform cluster. The bootstrap VM connects to the baremetal network and to the provisioning network, if present, via the network bridges.

Deployment phase one

When the installation of OpenShift control plane nodes is complete and fully operational, the installer destroys the bootstrap VM automatically and moves the virtual IP addresses (VIPs) to the control plane 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.
