4. www.softserve.ua The 12 Factor App by Heroku The twelve-factor app is a methodology for building software-as-a-service apps that: • Use declarative formats for setup automation • Have a clean contract with the underlying operating system • Are suitable for deployment on modern cloud platforms • Minimize divergence between development and production • And can scale up without significant changes to tooling
5. www.softserve.ua The philosophy how to build apps: – Dev-Prod parity – Dependency management – Configs – Reproducible build process The 12 Factor App by Heroku
6. www.softserve.ua Is Vagrant the solution? • Virtualized development made easy. • Create and configure lightweight, reproducible, and portable development environments. http://vagrantup.com/
7. www.softserve.ua Why Vagrant? • It’s easy and highly configurable. • It is using existed time proven solutions: – VirtualBox – Chef/Puppet(you can use it as your playground) • It’s reproducible • It’s scalable • No divergence. Development = Production
8. www.softserve.ua Vagrant disadvantages: • It works better on Linux • It requires fast PC(a lot of RAM, SSD) • 3-rd party boxes updated rarely
9. www.softserve.ua Vagrant building blocks • The base box $ vagrant box add lucid32 http://files.vagrantup.com/lucid32.box • The VagrantFile Vagrant::Config.run do |config| config.vm.box = "lucid32" end • Provisioning – Chef or Puppet or what you like(shell scripts?) • The Vagrant VM
10. www.softserve.ua Using existing boxes http://www.vagrantbox.es/ • Major linux distributions and others OS: • RHEL/CentOS • Debian/Ubuntu Server • OpenSUSE • Slackware/Gentoo/Archlinux • OpenBSD/FreeBSD • Scientific Linux
11. www.softserve.ua Existed projects • vagrant-lamp • vagrant-wordpress • vagrant-php-dev-box • rails-dev-box • vagrant-python
12. www.softserve.ua Demo of using customized rails-dev-box
13. www.softserve.ua Conclusions • Vagrant encourage you to use good development practices • Vagrant is nice playground for Chef/Puppet • Vagrant is Fun
