apiVersion: extensions/v1beta1 errors about demo HOT 4 CLOSED

Hey @thescott, thanks a lot! Very helpful bug report. This is to be expected since Deployments were deprecated out of extensions/v1beta1 in the recent Kubernetes update.

We debated whether to make all our examples use apps/v1, but at the time, there were many Kubernetes installations which were too old to support this. Time moves on, so in the next edition of the book, should there be one, we'll target apps/v1! Meanwhile, we'll make the change in the online examples.

Thanks for opening the issue @thescott! Here is a PR to update the examples: #15
