Hi, Puppi is a shell tool, installed and configured bythe omonimous Puppet module, that has basically 2 functions: 1- Manage application deployments 2- Provide an handy bash command with data driven by Puppet
For the first task there are a bunch of puppet defines that allow you to define a deployment procedure (and some ready to use deployments samples good for many different uses (defined in manifests/projects/*.pp )). These defines, that you configure on puppet, provide to you the possibility of executing, on your nodes, commands like "puppi deploy myapp" or "puppi rollback myapp" to manage deployments. For the second task you need modules that actually can drive data to Puppet (Example42 ones do), but it's not too difficult to feed custom configurations to populate the output of actions like puppi check (does an immediate health check of your system and its applications), puppi info [app] (show information about your system and applications), puppi log [app] (tails all the configured logs). Since the command is always one (puppi) and the actions are always the same (deploy, rollback, check, info, log etc) you can easily uniform some operations on your infrastructure (whatever are the operations you have to do for a deploy, you have to run "puppi deploy something"). Puppi, of course can be run directly from the shell , but also via a jenkins ssh command (allowing only a "sudo puppi") or via mcollective (via the mc-puppi plugin) , or as a command that interacts with other orchestration / remote execution tools. I found it extremely useful on a variegated environment, managed by a team of various people, where there are many different kind of servers with diffferent deployment needs (wars, tarballs, maven artifacts, git sources and so on) and where it has been possibly to streamline and make it easy to make a deployment (if you just write 'puppi' you see also the available projects / apps you can deploy on the local nodes). Also, when configured with sane checks, it's very handy to write "puppi check" on a node and see if everything is going fine on it: at system / services / application levels (if you add, for example, url based checks (all checks are based on Nagios plugins). Hope to have given you a clearer view on puppi, I'm actually aware that the documentation is not good and somehow scattered on different places (what have you seen? the README on the git repo?) I'm at disposal to answer to any question about it and eventually to suggest you the possible Puppet code you can write to manage an application deployment you may need.
