README

        
Do you know the situation? You get a new server, start installing and

configuring stuff, then install additional services every couple of

month. And after some years decide to relocate to a new server or to

split: move *some* services to a new server. And then you think: "What a mess, how

long will it take until it perfectly configured and runs again - should

I better stay with the old one as long as possible?" ;-)

What about Zero day exploits? You think, you system could have been

compromised and need to reinstall everything as soon as possible.

Approaches I have already used:

* **Document every configuration step in wiki.** Can be a big help, but does

  not work automatically on the next installation - you still need to

  interpret and manually run single steps. No automatic testing.

* **Use [etckeeper]() with git to record the configuration changes.**

  Gives you later a clue, what has been changed. But the diffs are not

  automatically applicable on new installation, for example for a newer

  version

Now I decided to use [puppet]() for all newer installations.

Assumptions/prerequisites

* we will use a script for bootstraping, after that - puppet 3.0.

  Puppet supports multiple (almost all) Linux distributions. For the

  bootstrap scripts I'll start with Ubuntu/Debian and add Fedora/RedHat

  later.

* **Ruby 1.9** Bash programming can be cumbersome - so use Ruby and nice

  DSLs like Rake, Capistrano with their easy readable syntax for all non trivial

  tasks. 1.9 is now available in all recent Linux distributions - so use

  that. In Ruby 1.9 the rubygems is included - makes easy to install

  additional libraries (gems). Some libraries will be "vendored" though.

  E.g. `trollop` for nice command line tools.
