  +Install the Cloud Foundry Command Line Interface (cf CLI), and use the [cf env](http://cli.cloudfoundry.org/en-US/cf/env.html) command to view the Cloud 
  +Foundry environment variables for your application. 
  +The `cf env` command displays the following environment variables:
   
   * The `VCAP_APPLICATION` and `VCAP_SERVICES` variables provided in the container environment
   * The user-provided variables set using the [cf set-env](http://cli.cloudfoundry.org/en-US/cf/set-env.html) command
  
positive.code: 
  ### <a id='VCAP-SERVICES'></a>VCAP\_SERVICES ###
  
  For [bindable services](../services/) Cloud Foundry will add connection details
  to the `VCAP_SERVICES` environment variable when you restart your application,
  after binding a service instance to your application.
  
  The results are returned as a JSON document that contains an object for each
  service for which one or more instances are bound to the application.
  The service object contains a child object for each service instance of that
  service that is bound to the application.
  
negative.code: 
  ### <a id='VCAP-APP-HOST'></a>VCAP\_APP\_HOST
  
  The IP address of the host. Deprecated: the DEAs set this to be `0.0.0.0`, and 
  Diego Cells do not provide this environment variable.
  
  `VCAP_APP_HOST=0.0.0.0`
