* Continuous Integration Packaging with FPM -- [[User:japhy|japhy]]

** Code snippets with comments for the build system: https://gist.github.com/2823575

** Vagrant, a convenient command-line tool for running VirtualBox virtual machines (VMs): http://vagrantup.com/

** FPM (Effing Package Management), the main actor: https://github.com/jordansissel/fpm/

** Buildbot, the continuous integration server: http://trac.buildbot.net/ (alternative for open source, Travis CI: http://travis-ci.org/)

** Articles about setting up Buildbot by Jacob Kaplan-Moss, creator of Django:

*** Part 1, http://jacobian.org/writing/buildbot/ci-is-hard/

*** Part 2, http://jacobian.org/writing/buildbot/configuration-and-architecture/

** Runit, a sane reimplementation of Dan J. Bernstein's daemontools under BSD-like license. A tool for managing long-running services (I'd say "daemons", but they don't daemonize – they are managed by runit when running in the foreground): http://smarden.org/runit/

** LXC - Linux Containers, a lightweight userspace virtualization for Linux (may be used for real clean builds or for testing the packages): http://lxc.sourceforge.net/

** The Debian Policy Manual: http://www.debian.org/doc/debian-policy/index.html#contents

FPM is a command-line tool that converts between different package formats (from: local directory, ruby gem, php pear, python module, node.js npm package, deb, rpm; to: local directory, deb, rpm, solaris, tar). The "local directory" pseudo-format allows for easy creation of quick-and-dirty packages that Just Work, short-circuiting all the layers from the Debian Policy Manual all the way up to dh_make with one quick script call. FPM doesn't care about actually building your stuff (as in: unpacking, configuring, compiling, etc). It just takes directory you put it into, and turns it into a package. To prepare the compiled files and put them in the right place first is your job. So is specifying the dependencies - there are no automatic dependencies on dynamically linked libraries.

Workflow for the continuous integration using bits & pieces from the gist:

** On developer's workstation, "vagrant up" command brings up new VirtualBox VM with clean Debian and sets up a clone of the "packages" repository with a local branch

** "vagrant ssh" to the VM, go to the packages repo, prepare or modify new package, test it

** "git push" from the VM to the "develop" branch on the host server

** "git pull . develop" on the host server's master branch to merge

** "git push" to central git repo

** buildbot (continuous integration server) picks up the commit

** buildbot builds changed package and adds it to the apt repo

** new package is available to clients via apt-get within minutes from the push.

# Tier1 Hardware (Dell, HP, IBM) show & tell [[User:robe|Michael]]

#* We're going to look at a Dell R200, HP DL380G5 as well as a IBM x3650 M3 and see how they fare in regards of hardware maintenance, configuration, out of band management and general pain points.

# What hardware should I get anyways? General thoughts on performance evaluation, capacity planning, daily operations and other pitfalls.
