A hands-on, step-by-step guide to assembling a Kubernetes cluster from the ground up (without using any automation) while deeply exploring each component's role and functionality along the way.

Hey there! I built a learning-by-doing platform for DevOps, SRE, and all other types of infra engineers - https://labs.iximiuz.com. Started working on the project exactly two years ago, and about 12 months ago added a Premium membership, which immediately took off! Still mind-blown by the results, and it's something I build only in my free (from the main job) time. The labs were making ~$3K MRR for a few months before the Black Friday sale and then doubled the annual revenue in a week by making another ~25K at the end of this November.

I'm building a visual Kubernetes Explorer https://github.com/iximiuz/kexp. Because learning Linux & Containers can be fun.

I wrote this a while ago https://iximiuz.com/en/posts/computer-networking-101. You may find it useful.

Thanks for sharing! :)

Containers for sure aren't a replacement for VMs. And indeed, VMs still have and will have legitimate use cases. There is actually a relatively simple way to turn a container into a VM. Maybe you'll find it useful https://iximiuz.com/en/posts/from-docker-container-to-bootab...

It does work! Actually, it's my favorite type of containers so far https://iximiuz.com/en/posts/not-every-container-has-an-oper...

I still have a hope that increasing awareness of the problem may eventually lead to a reduction in the number of Dockerfiles starting `FROM <something_huge_and_not_really_needed>`.

Thanks a bunch!

Thank you very much for your feedback! I appreciate it a lot because at the end of the day that's what keeps me motivated!

Well, to be honest, some level of sarcasm was meant to be in this title because it precedes a 4000+ words explanation of the topic... But seems like I'm pretty bad at writing good titles. For sure I didn't mean to make anyone feel bad.

To try it out yourself, you need to build https://github.com/iximiuz/conman and https://github.com/iximiuz/shimmy from the source code (see the corresponding README files) and then execute a series of commands from the screencast.

You can read more about my educational effort to develop a Kubernetes CRI-compatible container manager in the introductory article https://iximiuz.com/en/posts/conman-the-container-manager-in....

A new article in the educational series on the experimental container manager development exploring what is a container runtime shim and how to create yet another one.
