Intoduction

This project provides an example of setting up a server with Chef and deploying a Ruby on Rails application do it with Capistrano

Getting Started

1. Install VirtualBox
2. Install Vagrant
3. git clone [email protected]:smartlogic/chef-cap-demo.git
4. cd chef-cap-demo
5. bundle install
6. vagrant up
7. vagrant ssh-config --host chef_cap_demo >> ~/.ssh/config

Chef

1. cd chef-repo
2. bundle install

Vagrant boxes already have chef installed, but lets install with our own bootstrap file to provide a good example for when you aren't using Vagrant. See chef-repo/.chef/bootstrap/precise32_vagrant.erb to see how Chef gets installed

1. bundle exec knife bootstrap -p 2222 -x vagrant -d precise32_vagrant chef_cap_demo
2. bundle exec knife cook vagrant@chef_cap_demo

Check to see if you can login as the deploy user

ssh -l deploy chef_cap_demo

Chef cookbook for the app

Create a chef cookbook for your application

1. git checkout app_cookbook
2. bundle exec knife cook vagrant@chef_cap_demo

ssh -l chefcapapp chef_cap_demo

Capistrano

Setup Capistrano

1. cd ..
2. git checkout cap_setup
3. bundle
4. bundle exec cap chef_cap_demo deploy:setup deploy:migrations

Capistrano tasks

Create a capistrano task to run our rake task as part of deploy

1. git checkout cap_data
2. bundle exec cap chef_cap_demo deploy

Proof

1. Open http://localhost:8080
2. See the messages left by Chef and Capistrano
3. cd chef-repo
4. bundle exec knife cook vagrant@chef_cap_demo
5. Refresh http://localhost:8080
6. Observe a new message from the Chef run
7. cd ..
8. bundle exec cap chef_cap_demo deploy
9. Refresh http://localhost:8080
10. Observe a new message from the Capistrano run
11. Both Chef and Capistrano created and will maintain a singleton entry that is not duplicated by additional runs

Starting over

1. vagrant destroy
2. vagrant up
3. Back to the Chef section
