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

Ubuntu Lucid 32- & 64-bit

see great Vagrant documentation

Vagrant 1.1.x

•Released 2 weeks ago

•PlugIn API

•New Providers (AWS, RackSpace, VMWare Fusion)

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

Vagrant.configure("1")

Puppet

Puppet

•configure your machines (nodes) by script

•install and configure software & services

•https://puppetlabs.com

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" endend path to Puppet script

Vagrant-Bindingconfigure & manage

VMs in Java

Vagrant-Binding

•Java Wrapper around Vagrant

•create & start VMs at runtime

•only VirtualBox is required

Vagrant-Binding

•Fluent 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();

builder API available

builder API for VM

manage VM lifecycle

ssh connection

JUnit support

@Testpublic 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?

parallel processes?

JUnit support

@Rulepublic VagrantTestRule testRule = new VagrantTestRule(createConfig());

public static VagrantConfiguration createConfig() { //Configure VM with MySQL-Server & static ip}

create VM start VM run UnitTest destroy VM

JUnit annotation manage VM lifecycle

use builder API for VM specification
