title: Is it possible for an environment variable to hold an array value in cloud foundry manifest?
body: <p>I am trying to push an app into cloud foundry, and pass an array value via environment variable.
  But I receive <em><strong>yaml: unmarshal errors:
  line 7: cannot unmarshal !!seq into string
  FAILED</strong></em></p>
  <p>manifest.yml:</p>
  <pre><code>---
  applications:
  - name: my-app1     # A default name for Cloud Foundry to give your app
    memory: 128M         # The amount of RAM required for each instance
    disk_quota: 256M    # How much disk space the application needs
    no-route: true
    health-check-type: none
    buildpacks:
      - https://github.com/cloudfoundry/nodejs-buildpack
    env: 
      countries: 
        - america
        - australia
        - japan
        - nertherland      
  </code></pre>
  <p>please Note: I validated my yaml via online validators and it looks good.</p>
