I've setup a Google Endpoint in front of a Google Container Engine service. The container is running Loopback, which serves the swagger UI by default at /explorer. I would like to access the UI, but of course the Google end point prevents accessing as it isn't part of the API spec.

Google has these docs, but they seem to be specific to an app engine deployment.

How can I go about exposing the swagger UI while using Google Endpoints, Google Container Engine and swagger?
