View Dockerized Node app in Google Cloud Compute

Following the instructions here, I have created a dockerized express hello world app. I've built the app on a Debien VM on Google cloud compute, with

docker run -p 49160:8080 -d myname/node-web-app

and in the shell I can see Running on http://localhost:8080. I'm confused though how I can access it in a browser. Going to the IP:8080 is getting a no data sent error.

How can I view my dockerized app in a browser?
