Prerequisites
To get the most out of this course, you should have:

Basic Linux command line and file editing skills and be familiar with using a programming language (such as Python, Node.js, Go). Knowledge of Cloud Native application concepts and architectures (such as is taught in our free Introduction to Kubernetes edX MOOC) is helpful for this course.

Please note, Kubernetes Administration (LFS458) is not a pre-requisite for this course. There is overlap in the course materials as each one is designed to stand alone and aligns with the related exams.

Reviews
Jan 2021
The instructor is obviously very knowledgeable in Kubernetes. He was able to explain very complex concepts on a whiteboard, and didn't just scan through a bunch of slides.
Jan 2021
Detailed knowledge of the domain, and extensive explanation of the subject in the workshop manual.
Jan 2021
Instructor was great, and the exam preparation material was a good touch.
Jan 2021
I liked the lab exercises. Well documented - the supporting documentation explaining the purpose of the exercises was good. The ability to review these exercises outside of the allocated training time was useful.
Jan 2021
Chris and his ability to describe completes things intelligibly.
Jan 2021
The lab exercises were well timed, I could finish them almost on time +- 2 minutes.
Oct 2020
We could cover a lot, and I liked the personal experience added by the trainer.
Oct 2020
The course is well structured, and the explanations were comprehensive and complete. Labs were interesting too.
Oct 2020
A nice introduction assuming no knowledge. Even with experience it was pleasant to take a step back and paint a big picture that is easier to understand. The context surrounding the creation and ecosystem of K8s was also nice.
Oct 2020
The trainer knew his subject well, and agreed to look into and answer some specific topics.
Oct 2020
The labs after each chapter are really good.
Sep 2020
Tim is very knowledgeable, he had answers to all the questions along with background knowledge.
Sep 2020
The labs were super useful as we could run things ourselves and be more involved.
Sep 2020
I like the overview about the course given to the new comers to Kubernetes.
Sep 2020
I liked the lectures (some good hints and heads-up shared, like RedHat going to drop Docker), and the labs.
Jun 2020
Tim is very good at covering all the content and answering questions. I learned quite a bit in this class and would definitely recommend this course to my team and others.
