Modifications in the Data Model

You must specify the Active and Standby node during the configuration explicitly because of the asymmetric HA configuration:

  1. Active Node - You must use the control plane node as the Active node. Using the k8s hostname-override parameter, you can specify the K8s host name (instead of using the default name).

    Example:

    nodes active
      k8s node-type control-plane
      k8s hostname-override ha-active
      ...
     exit 
  2. Standby Node - A new K8s node type called backup is introduced for the Standby node.

    Example:

    nodes standby
      k8s node-type backup
      ...
     exit
