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 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 OKD cluster. The bootstrap VM connects to the
baremetal network and to the
provisioning network, if present, via the network bridges.
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. The API VIP moves to the control plane nodes and the Ingress VIP moves to the worker nodes.
The API and DNS VIPs move into the control plane nodes and the Ingress VIP services applications that reside within the worker nodes.
