Just realized that I forgot an important point about timing - there's actually a few sessions in the upcoming Summit that might influence the design and implementation of PFS: * http://summit.openstack.org/cfp/details/50 - in the design Process Track. * There's one I proposed in the Summit's conference DevOps track (the abstract is below - Alas, I don't seem to be able to find a link to the session on the openstack site - the Conference session listing seems to have gone away). Having the feedback from these sessions, and reflecting it in the code might be beneficial in driving the upstreaming of these cookbooks. The Abstract: Let's eliminate the lag between coding and deploying, and make sure that when we call a release done, users can . use it. The rapid pace of code development and feature addition to Openstack projects leaves our users in the dust. Without a proven, tested method to deploy the latest bits, the goodness of code is of no use to users. As features are added, let's make sure that old deployment methods still work, and if they don't we can identify the required changes. (Trunk gate comes to mind!) To achieve that, we can't wait for Distros to package the code.. Test code as it comes in , and validate both the code and its deployment using methods that worked for the H-1 release. Breaks found in the deployment are breaks speared of the users.This session will describe a deployment pattern that can achieve this (We the Crowbar Team call Pull-From-Source). This pattern uses the production deployment form release H-1 to deploy the most recent gerrit snapshot, and validate it is functional using Tempest. > > > > So, anyone with good PFS knowledge who'd be willing to participate in > > an effort to help converge the two sets of cookbooks? :-) > > > > [1] https://github.com/att-cloud/cookbook-openstack- > common/blob/master/libraries/endpoints.rb > [2] https://github.com/att-cloud/cookbook-openstack- > common/blob/master/libraries/uri.rb > [3] https://github.com/att-cloud/cookbook-openstack- > common/blob/master/attributes/default.rb > [4] https://github.com/rcbops- > cookbooks/monitoring/blob/master/providers/metric_collectd.rb > [5] https://github.com/att-cloud/cookbook-openstack- > common/blob/master/libraries/default.rb#L29 > > > > > > > Cheers, > > > > Vincent > > > > -- > > Les gens heureux ne sont pas pressés. > > > > _______________________________________________ > > Crowbar mailing list > > Crowbar@dell.com > > https://lists.us.dell.com/mailman/listinfo/crowbar > > For more information: http://crowbar.github.com/ _______________________________________________ Crowbar mailing list Crowbar@dell.com https://lists.us.dell.com/mailman/listinfo/crowbar For more information: http://crowbar.github.com/
