Description Alexander Chuzhoy 2018-10-16 23:41:38 UTC

Need to document that if the network service is restarted - the keepalived container should be restarted too.

Otherwise on SSL enabled undercloud (default in OSP14) the public_host and admin_host IPs won't be available and you can see what happens:
