This Ansible role installs and configures HAproxy on a machine.
This role also supports having >1 haproxy in a failover scheme using a shared virtual IP with keepalived and VRRP.
Warning
Since ARM support is still in beta, at the moment there is no support for HAProxy 3.0 in RHEL/RHEL-derivatives running on ARM hardware.
Important
Please notice that the role will assume that if the machine hostname ends with -1, the machine will be configured as a keepalived MASTER and will have the highest weight.
