Shiny(ish) webapp that is a front end for mcollective based git deploy tool.
Elsewhere on Github, you should be able to find https://github.com/FuturePublishing/future-deploykit which contains (mcollective) command-line utilities for inspecting available tags in git repos on remote machines and optionally deploying same.
Matt wrote this, which is a Sinatra application and some Twitter Bootstrap bits that makes the command-line stuff less scary or less open to abuse, depending on which side of dev or ops you fall on when pushed.
Deploys that happen rapidly and via a single(ish) click are pretty cool. You should try them.
Beats me. Ask Matt.
Copy all the bits that aren't the 'initscript' directory to, er, /data/grabby. Install the initscript in /etc/init.d and employ whatever tool to create symlinks and ensure sensible ordering. You will also need an MCollective install that contains a user-login with the right runes to be able to issue MCollective commands.
You may also require some sort of access-control and/or logging on the relevant webserver. Since we had an AD install to hand, we used Apache's mod-kerberos, because then user management and p/w sharing become someone else's problem.
If it all fails dismally, make sure that you can drive your sacrificial/test repository with the command-line tools first.
