503 Service Unavailable using Docker Emulator (MacOS)

[bbehling]

I receive a 503 service unavailable error when trying to write to the emulator service. I can access the service through the web browser explorer. Even attempting to upload a document through the explorer results in an error.

To Reproduce
Follow the steps here to create a service from the docker image.

Additional context
Note the RequestURI above, https://172.17.0.2:8081/dbs/preapproved/colls/zipcodes. 172.17.0.2 does not exist. I've tried pinging that address and nothing is found. Its the emulator supposed to spin up services at that address?
