Changing the --server parameter

1

In a HA, external data store cluster we now have an external Load Balancer for the API on port 6443.

Until now we started nodes with the --server master1.domain.com:6443 but master1 may go down. How do we now configure all nodes (in a 2-master cluster) to know the new virtual IP for this Load Balancer?

Since we use a YAML config is it a case of updating the file to include it?

server: ourlb.domain.com:6443

Or do they get this parameter from the DB? If so how do we change it?

Actually, setting this appears to have no effect. I’m wondering how the masters “find” each other.
