This is the sample application for Ruby on Rails Tutorial: Learn Rails by Example by Michael Hartl.

This sample has been modified to run on Cloud Foundry. The cf-autoconfig gem was added to enable auto-configuration of database connections as described in the Cloud Foundry documentation.

This project was forked and updated to use the Cloud Foundry MySQL Release as it does serve as an excellent example of best practices for BOSH packaging. I updated this repo so that I could better understand the cf-mysql-release by testing it with an application sitting on top of it.

The activerecord-mysql2-adapter gem was also added to support connection to MySQL database proxies provided by the cf-mysql-release.

After installing in the 'cf' command-line interface for Cloud Foundry, targeting a Cloud Foundry instance, and logging in, the application can be pushed using these commands:

First, view a list of services and plans available in your Cloud Foundry instance:

$ cf marketplace Getting services from marketplace in org me / space development as admin... OK service plans description p-mysql 100mb, 1gb MySQL databases on demand 

This is my marketplace, select the only service on the list and create a service instance named rails-mysql using a MySQL service and plan:

$ cf create-service SERVICE PLAN rails-mysql Creating service rails-mysql OK 

Now push the application:

$ cf push APP-NAME --random-route Using manifest file manifest.yml Updating app rails-sample OK Creating route rails-sample-desiccative-acetylizer.cfapps.io... OK Binding rails-sample-desiccative-acetylizer.cfapps.io to rails-sample... OK Uploading rails-sample... Uploading app files from: rails_sample_app Uploading 41.1M, 6349 files OK Binding service rails-mysql to app rails-sample OK Starting app rails-sample OK ... 0 of 1 instances running, 1 starting 0 of 1 instances running, 1 starting 0 of 1 instances running, 1 starting 1 of 1 instances running App started Showing health and status for app rails-sample OK requested state: started instances: 1/1 usage: 256M x 1 instances urls: rails-sample-desiccative-acetylizer.cfapps.io state since cpu memory disk #0 running 2014-05-29 03:34:22 PM 0.0% 50.3M of 256M 80.2M of 1G 

The application will be pushed using settings in the provided manifest.yml file. The --random-route option adds random words in the host to make sure the URL for the app is unique in the Cloud Foundry environment. The output of the cf push command shows the URL that was assigned. Using the provided URL you can browse to the running application.
