Hi there **👋**

I created a [**complete Kubernetes course**](https://youtu.be/X48VuDVv0do), which I think could be interesting for some (beginners) of you. If you're just getting started with Kubernetes, but maybe also good for refreshing some concepts.

  1. I \*just\* got a interview for a job using infrastructure as code and your videos appearing on my radar are nothing short of a godsend for me to get a crash course on all the prerequisite knowledge to bring me from a sysadmin to a infrastructure as code wizard. I’m going to spend all weekend watching your videos. From the bottom of my heart, thank you. If you have somewhere I can donate you some money, I’d love to donate some beer or restaurant money!

  2. Hi ! Nana.. is this different from the collab video with Amigoscode ? and great work ! we’ll are so blessed to learn from you .. Keep rocking and take care 🙂
