Installer Provisioned Infrastructure (IPI) installation provides support for installing OKD on bare metal nodes. This guide provides a methodology to achieving a successful installation.

During installation of IPI on bare metal, the installer on the bare metal node labeled as provisioner creates a bootstrap 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

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 appropriate nodes accordingly. The API VIP moves to the control plane nodes and the Ingress VIP moves to the worker nodes.
