This worked for me. I found the config.json file for the functions-emulator (It's in user/.config/configstore/@googlecloud/functions-emulator/config.json on mac or windows) and changed "bindHost": "localhost", to "bindHost": "0.0.0.0" and then I could access served functions from other devices on my network via localip:5000 which wasn't working before.

Digging around the code I figured this out, it's because the firebase-tools is only setting the projectId as part of the functions-emulator config. This fixes it in my Dockerfile

ADD config.json /root/.config/configstore/@google-cloud/functions-emulator/config.json

and the config.json looks like this

{
"bindHost": "0.0.0.0" }

You can change the 0.0.0.0 to any host you want, but this works for Docker.

For reference https://github.com/firebase/firebase-tools/blob/master/lib/serve/functions.js#L71 is the offending block, it needs to set the above parameter to the same as the --host command line parameter.

If you are running on your own local machine then you need to set it to the configstore folder for your respective OS on OS X it would be ~/.config/configstore/@google-cloud/functions-emulator/config.json.
