Title: Change nginx bind port so it doesn't conflict

Currently if you follow this guide when it comes to starting nginx you get this error:

Error starting userland proxy: listen tcp 0.0.0.0:8080

Because Kubernetes is already listening on :8080, so you can't bind nginx to :8080, so I've changed it to :8081
