Piping minikube start script into bash script fails to run full script

[eriknelson]

What date were you attending the hackathon?

12/13

What scenario were you running when you encountered the issue?

001 stateless app mirror

What did you expect to happen?

Copy pasted the minikube start script and it only ran half of the commands.

What actually happened?

Only the minikube commands run, it seems to stdout part of the script and not
all the commands run, so that when people go to run the examples they fail
in ways that are caused by bad networking.

Please include any relevant logs or errors

Workaround for this is to wget <script address directly to the machine and chmod +x that, then run it with ./minikube-start-script.sh
