Creating and Deploying a Simple Rails Application

Now that we’ve configured our servers to receive our applicaiton, let’s create one and deploy it! We’re going to create a simple Ruby on Rails applicaiton and us Capistrano for the deployment process.

Install Rails/Capistrano

Open up your Gemfile and add the following lines:

1 gem 'rails'

Now, run bundle install to install rails and capistrano:

Now, let’s configure our new application to use mysql and capistrano. cd into your new applicaiton directory:

1 $ cd myapp

and open the Gemfile there. Add the following lines:

1 gem 'mysql2'
2 gem 'capistrano'
3 gem 'therubyracer', :platforms => :ruby

Create a Simple People Page"

Next, we’re going to create a simple people page whee you can create, update and delete names of people in the database. Rails already has “scaffolding” which means we can do this without writing any code. :-)

Within the myapp directory, use the rails generate command to create the poeple scaffolding:

 1 $ rails generate scaffold Person name:string
 2       invoke  active_record
 3       create    db/migrate/20120927193700_create_people.rb
 4       create    app/models/person.rb
 5       invoke    test_unit
 6       create      test/unit/person_test.rb
 7       create      test/fixtures/people.yml
 8       invoke  resource_route
 9        route    resources :people
10       invoke  scaffold_controller
11       create    app/controllers/people_controller.rb
12       invoke    erb
13       create      app/views/people
14       create      app/views/people/index.html.erb
15       create      app/views/people/edit.html.erb
16       create      app/views/people/show.html.erb
17       create      app/views/people/new.html.erb
18       create      app/views/people/_form.html.erb
19       invoke    test_unit
20       create      test/functional/people_controller_test.rb
21       invoke    helper
22       create      app/helpers/people_helper.rb
23       invoke      test_unit
24       create        test/unit/helpers/people_helper_test.rb
25       invoke  assets
26       invoke    coffee
27       create      app/assets/javascripts/people.js.coffee
28       invoke    scss
29       create      app/assets/stylesheets/people.css.scss
30       invoke  scss
31       create    app/assets/stylesheets/scaffolds.css.scss

From the top: The rails scaffolding generator creates a heap of working code for us, including the database table migrations, test files, controllers, views, forms and all the glue necessary for it all to work together.

Let’s test out our application locally by migrating the database (creating new tables) and running the local server:

rake db:migrate
==  CreatePeople: migrating ===================================================
-- create_table(:people)
   -> 0.0010s
==  CreatePeople: migrated (0.0010s) ==========================================

Now point to your browser to http://localhost:3000/people. Click the New Person link and have some fun!

Back in the console, hit CTRL-C to quit the local development server. Before we start the deployment process, let’s delete the local development database and also take a look at the default database.yml file:

If you remember when we customized our webb server recipe, we created a custom database.yml that contained the correct information for the web server instances we’re deploying to. Rails best practices usually dictate that rails applications copy the stock database.yml [above] to database.yml.example, then tell git to ignore database.yml. The idea is that database.yml is never comitted to source code, keeping and server passwords private. Then during deployments, a server local version [like the one we have in our recipe] will be copied into place.

1 $ cp config/database.yml config/database.yml.example
2 $ echo "database.yml" >> .gitignore

Create Deployment File

We’re going to use Capistrano to deploy our application to the cagrant server instances. Within the myapp directory, run the capify command:

1 capify .
2 [add] writing './Capfile'
3 [add] writing './config/deploy.rb'
4 [done] capified!

Now, open config/deploy.rb in your editor and replace it’s contents with the following:

 1 require "bundler/capistrano"
 2 
 3 set :application, "myapp"
 4 set :deploy_to, "/var/www/myapp"
 5 set :deploy_via, :copy
 6 set :user, "myapp"
 7 
 8 set :rails_env, "development"
 9 set :use_sudo, false
10 
11 set :scm, :none
12 set :repository, "./"
13 
14 role :web, "10.10.10.10"                          # Your HTTP server, Apache/etc
15 role :app, "10.10.10.10"                          # This may be the same as your `Web` server
16 role :db,  "10.10.10.10", :primary => true # This is where Rails migrations will run
17 
18 after "deploy:finalize_update", "deploy:copy_database_yml"
19 
20 namespace :deploy do
21   task :start do ; end
22   task :stop do ; end
23   task :restart, :roles => :app, :except => { :no_release => true } do
24     run "#{try_sudo} touch #{File.join(current_path,'tmp','restart.txt')}"
25   end
26 
27   task :copy_database_yml do
28     run "cp #{shared_path}/database.yml #{release_path}/config/database.yml"
29   end
30 end

That’s a lot of code, but it’s pretty simple. Let’s brea it down.

On Line 1, we load the bundler/capistrano code. This makes the deployment process aware of bundle and Gemfiles.
Lines 3-6, we se the app name, the directory to deploy to, the deployment method (file copy) and the remote user to run the commands as. That’s the user we created in our customer recipes!
Lines 8-9, we set the default rails environment and disable sudo since the myapp user won’t need it.
Lines 14-16, we tell capistrano the server to deploy to, in this case, our local vagrant instances.
Lines 18 says “after updating, copy over the database yml we created” in our cookbook recipe.
Lines 20-29 tells capistrano how to make passenger restart the app, how to copy the database.yml file.

Deploy the Application

Now that we’ve got a deployment script, let’s ensure our vagrant instances are fully up to date, then use the deploy:setup and deploy:cold to deploy our application:

 1 $ cd ../instances/cluster
 2 $ vagrant up
 3 $ vagrant provision
 4 
 5 $ cd ../../myapp
 6 
 7 $ cap deploy:setup
 8   * executing `deploy:setup'
 9   * executing "mkdir -p /var/www/myapp /var/www/myapp/releases /var/www/myapp/shared /var/www/myapp/shared/system /var/www/myapp/shared/log /var/www/myapp/shared/pids"
10     servers: ["10.10.10.10"]
11 Password: myapp_1234
12     [10.10.10.10] executing command
13     command finished in 20ms
14   * executing "chmod g+w /var/www/myapp /var/www/myapp/releases /var/www/myapp/shared /var/www/myapp/shared/system /var/www/myapp/shared/log /var/www/myapp/shared/pids"
15     servers: ["10.10.10.10"]
16     [10.10.10.10] executing command
17     command finished in 17ms

From the top: The very first time we run capistrano to deploy to a server, we need to run the setup task. This creates all of the remote directories capistrano will ned in the future for itself and passenger, like log directories, pid directories, etc.

 1 $ cap deploy:cold

From the top: IF all goes well, the deploy cold task copied up your myapp source, installed the gems using bundler, copied the database.yml, and connected to the db server instance to migrate the database and create the table.

Let’s open up a browser and try it out: http://10.10.10.10/people

Let’s look around the servers and inspect our work!
