Per-Developer Vagrant Environments with Vagrant and Puppet

At the UNICOM DevOps Summit in February 2014, @jtopper presented on the use of Vagrant and Puppet for providing per-developer environments - including a live demo of the approach in action.

You can try the code yourself too, visit the GitHub Project and follow the instructions in the README. https://github.com/jtopper/vagrant-demo

1. Per-Developer Environments with Vagrant and Puppet ! Jon Topper The Scale Factory
2. Let’s talk about software versions.
3. Production 5.1.73 5.3.3 6.3
4. Pre-Production 5.1.73 5.3.3 6.5
5. Back-end Developer 5.5.35 5.5.3 13.10
6. Front-end Developer 5.1.72 5.3.28 10.9
7. Javascript Developer 5.6.16 5.5.9
8. Env OS PHP MySQL Prod RedHat 6.3 5.3.3 5.1.73 Pre-prod CentOS 6.5 5.3.3 5.1.73 Back-end Ubuntu 13.10 5.5.3 5.5.35 Front-end OS X 10.9 5.3.28 5.6.16 Javascript Windows 7 5.5.9 5.6.16
9. Why is this bad? ‣ Increased deployment risk ‣ Wasted developer time ‣ Wasted operator time
10. This is happening in your organisation right now! probably ^
11. Why is this good? ‣ Environments scale with number of developers ‣ Environments as portable as developer hardware
12. The Four Pillars Culture Automation Monitoring Sharing
13. A Solution
14. What is Vagrant? ‣ Tool for managing dev environments ‣ Supports Linux, Mac, Windows ‣ Integrates with CM tools (eg. puppet) ‣ Folder sharing ‣ As portable as your laptop
15. What is Vagrant? ‣ Import pre-defined “base boxes” from remote servers ‣ Describe box configuration in Vagrantfile ‣ Share both with other people ‣ “vagrant up” starts a clean, new environment ‣ “vagrant destroy” throws it away.
16. What is Vagrant? Operating System Webserver Text editor Browser Database Messenger Music Twitter Photoshop Filesystem
17. What is Vagrant? Operating System Webserver Text editor Browser Database Messenger Music Twitter Photoshop Guest O/S Filesystem
18. What is Puppet? ‣ Configuration Management tool ‣ “Infrastructure as Code” ‣ Convergent
19. What is Puppet? ‣ Describe desired system state ‣ “What”, rather than “How” ‣ Puppet moves system from current, to desired state
20. (Demo)
21. Benefits ‣ Repeatable ‣ Puppet can be used all the way from dev to live ‣ Parity with production builds confidence ‣ Configure once, deploy everywhere
22. Env OS PHP MySQL Prod CentOS 6.5 5.3.3 5.1.73 Pre-prod CentOS 6.5 5.3.3 5.1.73 Back-end CentOS 6.5 5.3.3 5.1.73 Front-end CentOS 6.5 5.3.3 5.1.73 Javascript CentOS 6.5 5.3.3 5.1.73
23. Try it yourself ‣ https://github.com/jtopper/vagrant-demo ‣ Follow the instructions in the README ‣ Open a new GitHub issue if you get stuck!
