This presentation accompanies a hands-on-lab session in which Puppet will be used to automatically provision Oracle WebLogic Server. Puppet is a tool to automate configuration management. Together with Chef it's one of the more popular configuration management tools at the moment. Puppet allows you to describe the desired (to-be) state of your servers by declaring resources. These declarations can describe user accounts, security settings, packages, directories, files, executable statements, services, and so on. Manifests are the files in which resource declarations are listed. Puppet periodically applies manifests by translating manifests into specific commands (catalogs) and executes those on the managed servers. Puppet is capable of inspecting the machines so it only applies those changes that are necessary. If a machine is already in the desired state Puppet will apply no changes.
