Ich weiss, wie meine Server aussehen.

Das Development soll maximal ähnlich sein.



Vagrant

39

VirtualBox-basierte automatische Erzeugung von VMs mit Puppet/Chef



Vagrant

40

Voll versioniert!On-Demand ErzeugungDeveloper-Self-Service



$ gem install vagrant$ vagrant box add maverick64 http://mathie-vagrant-boxes.s3.amazonaws.com/maverick64.box$ mkdir maverick_demo$ cd maverick_demo$ vagrant init maverick64$ vagrant up$ vagrant sshvagrant@maverick64:~$

ssh-for-loop on steroids

fast management for loads of servers

uses puppet/facter, MQ-based

The most dangerous vegetable on earth!

Feature: Manualsearch In order to find an article As an developer I want to use the search function Scenario: Search for bdd and check resulting page Given I go to "http://it-republik.de/php/" When I fill in "search_itr" with "bdd" And I click "search2" Then I should see "Suche"

http://it-republik.de/php/



Given /Î go to "([^"]*)"$/ do |url| visit urlend

Feature: Install inetd In order to serve the web the httpd service must be installed

Scenario: Setup httpd Given a node of class “web“ When I compile the catalog Then package “httpd“ should be “installed“ Then there should be a resource “Service[httpd]“ And the service should have “enable“ set to “true“ And State should be “running“ And the service should require “Package[httpd]“
