Closing and Evaluation Survey
Prerequisites
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.

The labs helped solidify the concepts for me. Drawing on the whiteboard also helped a lot.
Jul 2023
The quality of the lecture material by the instructor was top notch, and he was very accommodating.
Jul 2023
I thought the depth and breadth where excellent, enough to give me a strong understanding of some content, while still providing awareness of some more advanced capabilities.
Jul 2023
The instructor was very knowledgeable about the subject matter. When he could not address a question on the spot, he took the time to research and follow up with the answer at a later time, during the training session.
Jul 2023
Generally the flow of the course felt natural and smooth, and the content was tight and to the point.
