Some Kubernetes course instructions out of date/deprecated

The practical guide to Kubernetes course needs to be reviewed and updated. Specifically, there are several examples of deprecated flags or objects. So far, off the top of my head, this includes the use of --record, the use of gitRepo, and a few others.

Hi! @Garrett_anderson
Thanks for your concern. This course is in our revamp queue. we will soon update its all content and as well as add code executables in it.

that’s excellent news, thank you. Is there some way I can be notified when this is updated?
