Rick Lopez and Rainya Mosher presented on Rackspace's goal of deploying code from the OpenStack trunk on demand to production environments in a reasonable time without customer impact. They discussed strategies for package and distributing code, as well as deploying and testing. Challenges included code management issues from merges and conflicts, but Rackspace is working to remove local patches and implement non-disruptive upgrades. Testing in production environments at scale also poses challenges compared to development testing. Related sessions at the OpenStack summit covered continuous deployment, validation of OpenStack deployments, and testing strategies.
