Hello,

When the cluster gets created the default DNS domain that it gets is cluster.local , as of now there is no option for the user to set this to something else specific to their environment, like mycompany.com, etc.

If this field is provided during cluster setup on management plane, customers can use it to add the domain of their choice, if not specified, the cluster can get deployed with current default domain "cluster.local".

Thanks,

Niket Chavan
