OpenShift Bare Metal IPI Cluster

How it works

It uses VirtualBMC service in front of the cluster nodes. In the install-config.yaml file, the BMC information will be shared. The installer interacts with the VBMC to turn ON the nodes when it requires. To know more about VBMC, please see this.

Cockpit installation

The bare metal IPI cluster deployment does not require any configuration in OpenShift Network Playground. Once the ONP is ready, the onp deploy RELEASE=stable command can be executed to start the installation. The Cockpit also gives the option to do the deployment.

• Enter the release

• Enter OCM_TOKEN

• Click Deploy

The credentials of the newly deployed cluster can be shown by clicking the show button on the top.

CLI installation

To deploy the cluster using the CLI, the onp command can be used.

onp deploy RELEASE=stable OCM_TOKEN=<ocm-token>
