Start a puppetmasterd with project files:

./script/puppetmasterd &

 notice: Starting Puppet server version 0.24.5

Create and start a sandbox:

rake sandbox:setup sandbox:create sandbox:start

Follow sandbox console/syslog:

tail -f log/sandbox.log

List waiting client certificates:

./script/puppetca --list
sandbox

Sign the sandbox certificate:

rake sandbox:puppet:sign

Request a puppet run in sandbox:

rake sandbox:puppet:run

Install an external module:

./script/module install git://git.black.co.at/module-common  

install module common in modules/common

Create a new Puppet module

./script/generate module private

    create  
    create  manifests
    create  files
    create  templates
    create  README
    create  manifests/init.pp

For the moment, the sandbox tasks use qemu to create and run a virtual machine with a ready puppetd.

Define a sandbox in your rakefile:

Sandbox.new do |s|
  s.bootstraper = DebianBoostraper.new do |d|
    d.version = 'lenny'
    d.mirror = 'http://ftp.fr.debian.org/debian'
  end

  s.disk_size = '1G'
  s.memory_size = '128M'
end

Setup your host to create and start sandbox:

rake sandbox:setup

It installs qemu, kqemu module and uml-utilities

Create a fresh image for sandbox:

rake sandbox:create

By default, it will create a disk of 512M with a debian lenny.

Start a qemu instance with the sandbox image:

rake sandbox:start

Follow the console (and syslog) output of the sandbox:

tail -f log/sandbox.log
