For the past few weeks, I've been working on a big refactoring of HAProxy related manifests in Fuel Library, and now I am finally satisfied with how these manifests work in Ubuntu and CentOS.
It started as a fix for LP bug #1264388 and has brought up a long chain of problems that had to be resolved before the original problem could be addressed. The result is a massive 1318 line review request that completely rewrites the haproxy module (based on latest upstream version), refactors the haproxy parts of cluster and openstack modules, and touches osnailyfacter, galera, neutron, and ceilometer modules: https://review.openstack.org/65591 The primary purpose of this change is to make sure that HAProxy listening services can be enabled one at a time, after the corresponding backend service is configured and started (and releases the VIP if that's their default configuration), and before other services that require that service to be available via a VIP. The benefits are a more reliable and predictable HA deployment process, reduced coupling between our Puppet modules, and ability to put more services behind HAProxy without any impact on the core services. Please review this change and help me test it. See comments on the review for a list of configurations where this was tested, if this works for you in another configuration, please +1 and specify the configuration you used.
