Docker.Compose.yml - reference to Rides.Api

[SKApretto71]

The file Docker.Compose.yml refers to:

"image: bikesharingw-on.azurecr.io/ridesapi"

While I get that the "bikesharingw" is the Registry where this image is depoyed, the project for this application is not provided and hence the VSTS CI build pipeline fails missing such reference.

Questions:

1. Can it be pointed to a non Docker site, as deployed by the "Backend" reporitory from Bike Shareing 360 suite of applications, assuming this is the referenced application?
2. Is it used by the application, or can be just safely removed?
3. The Marketing site do refers two external Api in Settings.json file, but how to configure them is not specificied on compile and run guideline text. Can be a valuable addition.
