Spinnaker cannot create a load balancer for App Engine. A Spinnaker load balancer maps to an App Engine service, which is specified in a version's app.yaml.

For example, the following app.yaml

  			runtime: python27
  			api_version: 1
        …
  			service: mobile
        …
  		

deploys to the mobile service. If you do not specify a service, your version will be deployed to the default service.

If a service does not exist when a version is deployed, it will be created. It will then be editable as a load balancer within Spinnaker.
