Vagrant Up: your environment

It’s Friday 3pm. Your boss comes to you and asks you to set up a development environment for the new employee that arrives on Monday.

On another day, you have a sudden traffic spike and need to add a new server. Now you have to carefully follow a procedure without forgetting a step.

Sounds familiar?

In this presentation, Yann Larrivée will show you how Vagrant and Puppet can dramatically reduce the time needed to accomplish these tasks ans reduce the number of mistakes.

3. 3 Presentation Objectives  Increase software quality  Lower the time needed for quality assurance  Reduce the time needed to configure servers  Spend more time doing solving real problems
4. 4 You will learn how to: Vagrant  Manage a servers  Provision them with VirtualBox or DigitalOcean Puppet  Install / configure packadges  Use configuration templates  Create reusable scripts  ..
5. 5 What is:  VirtualBox: Hosted Hypervisor  Puppet: Configuration Management System  Vagrant: Provisioner
6. 6 Why use Vagrant & Puppet: Scenario #1  Windows/Linux/Mac  Different software version: PHP 5.5, 5.6, ..  Different software installed  Code breaks in production because of the later
7. 7 Why use Vagrant & Puppet: Scenario #2  New employee  No time to setup the machine
8. 8 Why use Vagrant & Puppet: Scenario #3  You want to create a standard environment  You need to create configured vm in seconds

15. 15 Vagrant: The Vagrantfile
16. 16 Vagrant: Customizing your VM  Machine name  RAM  CPU  Shared Folders  Network  Configuration manager (Puppet)  The Hypervisor (virtualbox, vmware, DigitalOcea, AWS)
17. 17 Vagrant: The Vagrantfile
18. 18 Puppet: Manifest & Resource Example
19. 19 Puppet:  Manifest  Modules  Classes  Define
20. 20 Puppet: Resources Types  Package  File  Service  Cron  Exec
21. 21 Puppet: Creating modules
22. 22 Puppet: The folder structure
23. 23 Vagrant: The Vagrantfile
24. 24 Vagrant: The Puppet Manifest
25. 25 Vagrant: The PHP Module
26. 26 Current Limitation  Everything is hardcoded  Specific to an OS  Can't customize any packadge configuration  Only configure one servers
27. 27 Why are we using puppet? • Write your manifest once • Configure always
28. 28 Hiera: Configuration Hierarchy  Key/value storage engine  Supports YAML & JSON
29. 29 Hiera: Configure Hiera
30. 30 Hiera: Configure Hiera
31. 31 Let's configure Waldo.box

37. 37 Vagrant Multinode: Vagrantfile
38. 38 Next step: In the cloud  AWS  DigitalOcean  Linode  ...
39. 39 In the cloud: Vagrant plugin
40. 40 In the cloud: The Vagrantfile
41. 41 In the cloud: Provisioning
42. 42 Presentation: Take away  Don't automate things while learning  Start small  Iterate  Automate once, configure always
43. 43 Presentation: Take away  We automate to go faster  Have a lab  Test your scripts  Be carefull, don't trust every box/scripts on the internet
