Vagrant

Vagrant

• configure virtual machines by script
• create new instances on the fly
• manage the VM lifecycle

Vagrant VM c r e a t e manage lifecycle

$ vagrant box add lucid32 http:// files.vagrantup.com/lucid32.box $ vagrant init lucid32 $ vagrant up

Vagrant

add template VM to Vagrant creates VM configuration-script s t a r t t h e v i r t u a l m a c h i n e

Vagrant

• build on top of VirtualBox
• written in Ruby

access by shell & Ruby

Vagrant

• provides 2 template boxes by default
• simple config-files
• easy ssh connection, shared folder, etc.

Vagrant::Config.run do |config| config.vm.box = "lucid32" end

Puppet

Puppet

• configure your machines (nodes) by script
• install and configure software & services

Puppet

class apache { exec { 'apt-get update': command => '/usr/bin/apt-get update' } package { "apache2": ensure => present, } service { "apache2": ensure => running, require => Package["apache2"], } } include apache Apache2 is installed & started on node

Puppet

• package individual components in modules
• many online documentations & books out

there

Vagrant & Puppet

Vagrant & Puppet

• define your VM with Vagrant & configure it

with Puppet

• Puppet is pre-installed on Vagrant boxes

Vagrant & Puppet

Vagrant::Config.run do |config| config.vm.box = "lucid32" config.vm.provision :puppet do |puppet| puppet.manifests_path = "manifests" puppet.manifest_file = "my_manifest.pp" end end

Vagrant-Binding

• Java Wrapper around Vagrant
• create & start VMs at runtime
• only VirtualBox is required

Vagrant-Binding

• Builder APIs
• JUnit support
• Puppet support

Builder API

VagrantVmConfig vmConfig = new VagrantVmConfigBuilder() .withLucid32Box() .withName("myLittleVm") .withHostOnlyIp("192.168.50.4") .build(); VagrantEnvironment environment = ...; environment.up(); environment.getVm(0).createConnection().execute("touch /tmp1"); environment.destroy();

JUnit support

@Test public void testJdbc() { dbHandler = new MySql(ip, db, user, pwd); dbHandler.createMyTable(); dbHandler.insertRow(); assertEquals(1, dbHandler.getRowCount()); dbHandler.close(); } what if table already exists? what if host not reachable? p a r a l l e l p r
