kubernetes: I can't reach service IPs on the network. Unable to access application from web.

Hi, I have my kubernetes environment up and running on an ubuntu machine with a master and two minion nodes. I’m able to fetch the nodes and list then.

I’m using https://github.com/GoogleCloudPlatform/kubernetes/tree/master/release-0.19.0/examples/update-demo i.e. to scale nautilus image. I’m unaware of which IP to use to view the images on the web page.
