Kubernetes Administration (LFS458)

This course covers the core concepts typically used to build and administer a Kubernetes cluster in production, using vendor-independent tools. We build a cluster, determine network configuration, grow the cluster, deploy applications and configure the storage, security and other objects necessary for typical use. This course offers exposure to the many skills necessary to administer Kubernetes in a production environment and is excellent preparation for the Certified Kubernetes Administrator (CKA) exam.

Who Is It For

This course is ideal for those wishing to manage a containerized application infrastructure. This includes existing IT administrators, as well as those looking to start a cloud career.

The structure was good, and the instructor was very friendly, helpful and cooperative.
May 2021
The instructor was responsive, and gave more than satisfying answers to our random questions, to the best of his ability. Once we asked something beyond the scope of his knowledge (we did ask some pretty tricky questions), that often reached beyond the scope of this course, he responded as best he could, provided resources for in depth information regarding the subject, and if he didn't know the answer, he didn't feed us nonsense.

Chris's experience and mastery of Kubernetes was quite evident during class. He was always answering questions, and staying positive. He guided us through challenges, and encouraged us to think, rather than rely exclusively on "copy paste" to get through lab exercises.
May 2021
I enjoy learning new and complex technical challenges. I went from having a very limited set of knowledge with Kubernetes, to being comfortable working within the environment.

May 2021
The "take-home" material is very nice to have for further study, and being reminded of what we've done in training. That's a huge plus for this course.
May 2021
How in depth the labs were! I've done the 'Kubernetes the Hard Way' labs to prepare for the CKA exam a few years ago, and it did not provide me with as much information on the 'How and Why' as this class and labs did.
May 2021
It had the correct level of complexity and depth. Not too detailed, but detailed enough to give us a good understanding of the nuances.
May 2021
The lab exercises are explained very well.

The teacher had really great examples, and explained the concepts and how the components link to each other really well. This greatly facilitated getting a high level grasp of Kubernetes, and looking up documentation for more specific details of each component.
Apr 2021
To actually have a trainer present, and be able to ask questions on the spot, makes it a LOT better than doing training with just recordings or reading material.
Apr 2021
Good design, nice introductory overview, with lots of pointers for deeper information that would fall outside the scope, but is useful to know anyway.

Even though this was a 4 day course, it was pretty light and easy to follow (maybe too light). Clarke did a good job.

I think the basics where well taught, and I feel like I have the information needed to start using Kubernetes.
