Installer Provisioned Infrastructure (IPI) installation provides support for installing OpenShift Container Platform on bare metal nodes. This guide provides a methodology to achieving a successful installation.
The bare metal node labeled as provisioner
contains two network bridges: provisioning
and baremetal
, each one connected to a different network. During installation of IPI on bare metal, the installer creates a bootstrap VM and connects it to both the provisioning
and baremetal
network via those bridges. The role of the bootstrap VM is to assist in the process of deploying an OpenShift Container Platform cluster.
When the installation of OpenShift control plane nodes, or master 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 and DNS VIPs move to the Control Plane nodes and the Ingress VIPs move to the worker nodes.
