3. A way of managing virtual machines • Run different operating systems • Define virtual machines in code • Save your own ass What is Vagrant? Tuesday, 19 March 13
4. Vagrant Who has tried Vagrant before? Tuesday, 19 March 13
5. Setting up a development environment • Often considered a right of passage • Takes hours, often requires support • Requires documentation that’s always frequently out of date • Breaking your development environment can kill productivity for days • Produces unpredictable results Why Vagrant? Tuesday, 19 March 13
6. Your development and production environment are not the same! • Different OS? • Different version of PHP/Python/Ruby? • Diverged package versions? • Different default configuration files? Why Vagrant? Tuesday, 19 March 13
7. • Update a website with a new feature. • The feature relies on a PHP module that is required by your web app • Module already installed on your laptop because another project that is hosted elsewhere needed it • It’s not a the server you deploy to, so the entire website stops working • You have no idea why, the same code worked on your machine • It worked on my machine! Why Vagrant? Tuesday, 19 March 13
8. • Vagrant configuration should be stored in version control • New developers can start developing quicker • Switch between projects, versions of PHP, languages with a few commands Why Vagrant? Tuesday, 19 March 13
9. • Vagrant lowers development environment setup time • Maximizes dev/prod parity • Makes the “works on my machine” excuse a relic of the past. from vagrantup.com Why Vagrant? Tuesday, 19 March 13

16. Configuration • Simple to configure using the Vagrantfile a text file which can be kept in version control • Easy to forward ports: Vagrant::Config.run do |config| # Forward guest port 80 to # host port 4567 config.vm.forward_port 80, 4567 end Tuesday, 19 March 13
17. Configuration config.vm.share_folder "v-data", "/data", "../data" Define shared folder Static IP config.vm.network '192.168.0.100' Set hostname config.vm.host_name = "steve" Boot with GUI config.vm.boot_mode :gui Tuesday, 19 March 13
18. Multiple VMs Vagrant::Config.run do |config| config.vm.define :web do |web_config| web_config.vm.box = "web" web_config.vm.forward_port "http", 80, 8080 end config.vm.define :db do |db_config| db_config.vm.box = "db" db_config.vm.forward_port "db", 3306, 3306 end end Tuesday, 19 March 13
