2014-03-06Fix Merge::Map for scatter-gather in Configs.Robert Collins1-1/+6
When Merge::Map was used like so: NovaCompute0Config: Merge::Map: NovaCompute0: Fn:.... We were adjusting the inner NovaCompute0 to the current scaling loop position rather than exploding it out as part of the map. For now, we want maps to be global in context so the fix is fortunately simple. Change-Id: Ibea723d4c763f593d934a9d2acfd31ce369f6408
2014-02-21Add a Merge::Map feature.Robert Collins1-0/+22
We need to scatter gather in a few situations - determining rabbit cluster membership, galera membership and configuring hosts for Nova to permit live migration (which requires host->host communication). This patch is a proof of concept for an eventual heat feature, expressed in merge.py. The example given should work for actual use, but I'll deliver that change separately.

2014-01-31Remove image parameter changing from mergeClint Byrum1-11/+19
The merge tool originally was meant to merge somewhat different things, and thus this was helpful in the early versions. However, at this point we want parameters to be more stable and we don't generally merge things that have their own image parameter. Meanwhile this feature caused problems as we change resource names. This is a backward incompatible change of default behavior, but the old behavior can be had again by passing --change-image-params.

2014-01-29Make scaling out a feature for merge.py.Robert Collins1-2/+104
This is a simple implementation designed to work with our current non-HOT approach. We need to adjust our templates a little to support this - though future work could make that better, it's orthogonal to this effort. Change-Id: I555617e5f24a5882de915f057dc02e008c81e753

2013-12-17Make merge.py installable as a package using pbrmarios2-0/+224
Now that merge.py is invokable from another script (Ia6b6416fe10358d23f2b120283eecaf4c1178cfd) and from comments at that review, it makes sense to offer a nicer way to consume the merge functionality. Once you git clone tripleo-heat-templates you can python setup.py install and get /usr/bin/tripleo_heat_merge as well as a tripleo_heat_merge package in python2.7/site-packages. Makefile edits required because we moved merge.py into the tripleo_heat_merge directory for the packaging. Change-Id: I587fa7a826f93f89e8e5c266af7f5765438fe738
