Deploying on OpenShift

• Create an account with Openshift.
• Install rhc gem using the following command.

sudo gem install rhc

• Complete rhc setup using the OpenShift's get-started page.
• Log into your OpenShift account and create an application using the web interface.
  • This will create a git repo on openshift.
  • Once application creation is completed a git repo link is provided.
• Clone the repo to your local workstation using link provided. Url looks something like this.

ssh://54038126c5ca47f5aa549052cc11cd8d@${app-name}-${namespace}.rhcloud.com/~/git/${app-name}.git/

• Let's say you have cloned it to $HOME/projects/app

$ cd app

$ mv config.ru config.ru.orig

$ cd ..

$ ramaze create app

$ cp $HOME/app/* $HOME/projects/app/ 

$ cd $HOME/projects/app

• Openshift uses bundler to manage dependencies. Install bundler using

$ sudo gem install bundler

• Create a Gemfile and Gemfile.lock
• Add the following entries to Gemfile

gem 'ramaze', '2012.04.14'
gem 'sequel', '3.40.0'
gem 'pg', '0.14.1'

• Run bundle install. This will update Gemfile.lock file with dependencies.
• Add all the files to git, commit and push.
• What's great about Openshift is for every push, it stops the server, builds, redepoys application and starts the server.
• Now go to the application link provided on your application creation page, you should see the Welcome to Ramaze Page.
