| apphosting_list_backends | apphosting | Retrieves a list of App Hosting backends in the current project. An empty list means that there are no backends. The `uri` is the public URL of the backend. A working backend will have a `managed_resources` array that will contain a `run_service` entry. That `run_service.service` is the resource name of the Cloud Run service serving the App Hosting backend. The last segment of that name is the service ID. `domains` is the list of domains that are associated with the backend. They either have type `CUSTOM` or `DEFAULT`. Every backend should have a `DEFAULT` domain. The actual domain that a user would use to conenct to the backend is the last parameter of the domain resource name. If a custom domain is correctly set up, it will have statuses ending in `ACTIVE`. |
