Description Ben Nemec 2020-01-22 09:26:02 UTC
Description of problem: The configuration templates for keepalived and haproxy do not support IPv6-based deployments. There are hard-coded values that do not work correctly with v6 addresses. We need to change these values to ones that will respect both v4 and v6 addresses.

frontend  main
  bind :::7443 v4v6

keepalived.conf contains only localhost which is resolved to matching protocol
