The simplest thing that does something Vagrant.configure("2") do |config| config.vm.box = "precise64" config.vm.box_url = "http://files.vagrantup.com/precise64.box" config.vm.provision "shell", inline: "echo hello, this is a simple Shell Provisioner!" end

1. Ansible Syntax YAML Scripts Playbooks Execution Order Sequential Modularity Many built-in modules Popularity Third most used provisioner Documentation Clear, objective Note: requires installation of extra package (ansible).

Slide 14

Slide 14 text

1.1 Vagrantfile config.vm.provision "ansible" do |ansible| ansible.playbook = "playbook.yml" end

Slide 15

Slide 15 text

1.2 Ansible: playbook #simple playbook example --- - hosts: all sudo: true Tasks: - name: Update apt apt: update_cache=yes - name: Install Nginx apt: pkg=nginx state=latest

2. Puppet (puppet-apply) Syntax Custom based on Ruby Scripts Manifests Execution Order NOT Sequential Modularity Very easy to find modules on the Internet Popularity Most used provisioner for Vagrant Documentation A bit confusing

Slide 18

Slide 18 text

2.1 Vagrantfile config.vm.provision :puppet do |puppet| puppet.module_path = "modules" end

Slide 19

Slide 19 text

2.2 Puppet: manifest #manifests/default.pp Exec { path => [ "/bin/", "/sbin/" , "/usr/bin/", "/usr/sbin/" ] } exec { 'apt-get update': command => 'apt-get update', } package { 'nginx': ensure => "installed", require => Exec['apt-get update'], }

3. Chef (chef_solo) Syntax Ruby Scripts Recipes Execution Order Sequential Modularity Many “cookbooks” available on the Internet Popularity Second most used provisioner Documentation Chaos!

Slide 22

Slide 22 text

3.1 Vagrantfile config.vm.provision "chef_solo" do |chef| chef.add_recipe "nginx" end

Slide 23

Slide 23 text

3.2 Chef: recipe #cookbooks/nginx/recipes/default.rb execute "apt-get update" do command "apt-get update" end apt_package "nginx" do action :install end

6.1 Debugging ● Unknown Vagrant error – Use VirtualBox / Vmware GUI ● Unknown Provisioner error – Increase provisioner verbosity ● Not working as expected – Login, fix, automate

Slide 27

Slide 27 text

6.2 NFS Performance ● Synchronization has a cost ● Symfony cache/logs – Too much writing operations on disk – We don't need this in our synced folder
