One possibility would be to have a third-party service that would handle the instantiation of a service from some declarative description. Say, you specify a docker container and the service would run it and would tell the given server is running as the specific docker container. (so it would depend on the authority of the service). However, you wouldn't have a possibility to "log in" to a container or interfere with it in any deep way, because it would break the concept. I think that the "serverless" concept already treats the running service as an immutable thing so probably adding the proof of running from a specific checkout would be easier there.
