Repo containers does not fit to video learning on O'Reilly Kubernetes

[jogi-k]

Just watching/learning on O'Reilly the Kubernetes-Training which tells you to clone containers from here. But the content seems to be quite different. Finally found the "original" content here: https://github.com/benyjaykay/sandervanvugt

It would be nice if repositories which are used in video learnings would not be changed...

I have same issue. While cloning this repo seems below docker instruction is used but sander.repo file is empty which throws error while building docker image as below.

ADD ./sander.repo /etc/yum.repos.d/
