Red Hat Bugzilla – Bug 1033247
[RFE] Global Parameter Boolean for Specifying Service Deployment
Last modified: 2016-04-26 09:37:12 EDT
This is a request to provide boolean values within the parameters section of host groups to disable specific services. For example, if a user wants to apply the host group of nova, but does not want ceilometer or heat to start they could set FALSE on a parameter named "ceilometer". Ideally the services would be built into nested host groups, but since we don't have that and are using packstack this is a temporary fix.
I am going to take this request as the following: Update the 2 controller host groups (Nova and Neutron), and make each service configured in those host groups optional vi a bool flag. If something different is requested, please provide further detail.
@jay, that is correct. If the level of effort to make this happen is high then maybe we should try to solve it through https://bugzilla.redhat.com/show_bug.cgi?id=1033261 instead of focusing on this very specific request as 1033261 might yield the same result in a different (and better) way. We should discuss this in more detail.
if we want to back-port this to the neutron/nova host groups we should clone it but it is more likely that we'll just start advocating single node clusters w/o load balancing as the base setup
Tested by setting all parameters beginning with "include_" on quickstack::pacemaker::params to "false" initially and ran puppet. Then started enabling services (switching parameters beginning with "include_" to "true") and re-running puppet. First i enabled qpid, then keystone, then others. Services got set up as i was enabling them. Used external MySQL node via quickstack::hamysql::singlenodetest class.
