This session will describe how puppet is used in Packstack, where we are using puppet as part of a run once installer, to deploy OpenStack in a distributed environment. During this talk we will discuss the benefits and pitfalls of applying puppet manifests to deploy OpenStack. Derek Higgins Senior Software Engineer, Red Hat Working in Red Hat Derek's main focus has been on OpenStack Deployments, where he uses Puppet and Foreman to deploy OpenStack. Derek also started the packstack install utility which applies puppet manifests to setup OpenStack in a multi host environment. Derek is still relatively new to puppet but is eager to learn all of the features it has to offer.
