Set up the control plane nodes

The control plane nodes, which are also known as master nodes, contain the services that are used to manage the cluster.

A minimum of three control plane nodes are required. For each control plane node, complete the following steps:

  1. From the VDC Instances page, click the Actions menu (Screen capture of the Actions menu icon) next to the instance. Then, click Start Instance to start the control plane instance:

  2. Quickly establish an SSH session with the control plane node to see the boot menu. After the Instance is Powered ON, it will automatically boot from the pre-selected option: LOCAL DISK. We want to boot first from MASTER (BIOS), then from LOCAL DISK.

    Choose MASTER (BIOS) from the menu:

  3. Choose BOOT FROM LOCAL DISK.

    The control plane node is rebooted.

  4. After the node reboots, run the following command to install OpenShift.
    $ ./openshift-install  wait-for bootstrap-complete --log-level debug --dir=/root/ocp-44/install

  5. After the command completes successfully, you can shut down the bootstrap instance from the VDC Instances page.

Repeat these steps for all control plane nodes.
