Installer-provisioned installation on bare metal nodes deploys and configures the infrastructure that a OpenShift Container Platform cluster runs on. This guide provides a methodology to achieving a successful installer-provisioned bare-metal installation. The following diagram illustrates the installation environment in phase 1 of deployment:
The provisioning node can be removed after the installation.
Provisioner: A physical machine that runs the installation program and hosts the bootstrap VM that deploys the controller of a new OpenShift Container Platform cluster.
Bootstrap VM: A virtual machine used in the process of deploying an OpenShift Container Platform cluster.
Network bridges: The bootstrap VM connects to the bare metal network and to the provisioning network, if present, via network bridges,
In phase 2 of the deployment, the provisioner destroys the bootstrap VM automatically and moves the virtual IP addresses (VIPs) to the appropriate nodes. The API VIP moves to the control plane nodes and the Ingress VIP moves to the worker nodes.
The following diagram illustrates phase 2 of deployment:
