Netplan and high availability

[cdmiller]

Hello,

We have some systems still using keepalived or corosync/pacemaker
for high availability with IP fail over.  Easiest case would be a
haproxy or nginx fail over pair.

Currently netplan removes interfaces it does not manage on any
change (netplan apply).

Please point me to some recommendations for implementing a high
availability cluster or pair in Bionic with IP fail over.

Thanks,
