This app is an example of how you can consume the Dingo Redis service within an application.
The app provides an API to end users (for example curl commands) to get/set/delete key value pairs. The data is stored in a Dingo Redis service instance.
Check that Dingo Redis has been installed by your platform operators:
cf marketplace -s dingo-redis
The output might look like:
Getting service plan information for service dingo-redis as admin...
OK
service plan description free or paid
ready Redis node free
Deploy the app by pushing it to your Pivotal Cloud Foundry and binding with the Dingo Redis service:
git clone https://github.com/dingotiles/dingo-redis-example-ruby-app
cd dingo-redis-example-ruby-app
cf push --no-start --random-route
cf create-service dingo-redis ready redis
cf bind-service dingo-redis-example-ruby-app redis
cf start dingo-redis-example-ruby-app
The final terminal output will include the URL:
requested state: started
instances: 1/1
usage: 256M x 1 instances
urls: dingo-redis-example-ruby-app-noncash-bisphenoid.apps.pcf110.starkandwayne.com

In the example above, the application is now running at https://dingo-redis-example-ruby-app-noncash-bisphenoid.apps.pcf110.starkandwayne.com.
The app's API can be interacted with using curl to PUT, GET, and DELETE values, which in turn are stored/fetched/deleted from a Dingo Redis service instance.
Sets the value stored in Redis at the specified key to a value posted in the 'data' field. Example:
$ export APP=https://dingo-redis-example-ruby-app-noncash-bisphenoid.apps.pcf110.starkandwayne.com
$ curl -k -X PUT $APP/foo -d 'data=bar'
success
Returns the value stored in Redis at the key specified by the path. Example:
$ curl -k -X GET $APP/foo
bar
Deletes a Redis key spcified by the path. Example:
$ curl -k -X DELETE $APP/foo
success
$ curl -k -X GET $APP/foo
key not present
