Quickstart rails application for openshift.
The easiest way to install this application is to use the [OpenShift Instant Application][template]. If you'd like to install it manually, follow these directions.
These are some special considerations you may need to keep in mind when running your application on OpenShift.
Your application is configured to use your OpenShift database in Production mode. Because it addresses these databases based on OpenShift Environment Variables, you will need to change these if you want to use your application in Production mode outside of OpenShift.
Your application is set to precompile the assets every time you push to OpenShift. Any assets you commit to your repo will be preserved alongside those which are generated during the build.
Since these quickstarts are shared code, we had to take special
consideration to ensure that security related configuration variables
was unique across applications.
To accomplish this, we modified some of the configuration files (shown
in the table below).
Now instead of using the same default values, your application will
generate it's own value using the initialize_secret
function from lib/openshift_secret_generator.rb
.
This function uses a secure environment variable that only exists on
your deployed application and not in your code anywhere.
You can then use the function to generate any variables you need.
Each of them will be unique so initialize_secret(:a)
will differ
from initialize_secret(:b)
but they will also be consistent, so any
time your application uses them (even across reboots), you know they
will be the same.

Create a rails application
rhc app create -a railsapp -t ruby-1.9
Note: To support Ruby 1.8,
+++ config/initializers/wrap_parameters.rb @@ -5,7 +5,7 @@ # Enable parameter wrapping for JSON. You can disable this by setting :format to an empty array. ActiveSupport.on_load(:action_controller) do - wrap_parameters format: [:json] + wrap_parameters ({:format => [:json]}) end
1. Add database support to your application
```
rhc cartridge add -a railsapp -c mysql-5.1
```
or
```
rhc cartridge add -a railsapp -c postgresql-9.2
```
1. Add this upstream Rails quickstart repository
```
cd railsapp
git remote add upstream -m master git://github.com/openshift/rails-example.git
git pull -s recursive -X theirs upstream master
```
1. Push your new code
```
git push
```
1. That's it! Enjoy your new Rails application!
