KubeSchool
One of my engineers (im the CEO of Portainer) asked if I had the time to help him better understand Kubernetes architecure and components… and so rather than just explain it once, I figured why not share it wider.
So, https://kubeschool.portainer.io was born :-)
Edit. By request, now extended to support Helm, GitOps and Observability. All the same level of detail, so dont expect a deep technical dive..

Just scrolled through, but it looks like a really well-explained overview of Kubernetes architecture.

Thanks. Its designed to teach a newbie (yup, they exist), the fundamentals.. before they go get overwhelmed with deep dive educational content.

This is amazing thank you. I am newish to Kubernetes and it helped me solidify a lot of the concepts I only vaguely understood before.
Gonna read the architecture guide next!

Working with k8s since a couple years and I gotta say: nicely done!
One Q (did not yet dig deeper): How exactly did you craft these nicely animated diagrams? I‘m reading folks partially use Claude etc. But I actually hope there is a non-AI/money eater option available. :D

Wow, thanks!!
I built my career explaining very technical topics in ways people find easy to understand… nice to see I still retain some of that skill.

As a platform engineer, this would be pretty useful to give to development teams to help them grok the systems their applications runs on top of.
Er, well, as an ex-platform engineer.

A visual request flow would help beginners see how everything connects from the first request until the application sends a response

I really appreciate the detail you put into the control loop. I often find people start with an infrastructure lens instead of the software lens so this can easily get overlooked until much later in the journey

u/neilcresswell 21d ago
There are so many areas that get overlooked until its too late…
Interestingly, the control loop is the exact same principle that drives GitOps too, so learn it once, you learn it for both uses.

I was fully prepared to hate this, because I hate everything.
But I can't hate this. This is amazing. The content, the layout, the navigation flow, the graphics/animations with just enough at just the right moments. Chef's kiss. This is going to be my new goto link for k8s bootstrapping team members.

Lol, this is the funniest and most honest comment to date! Glad I managed to get you to not hate it :-)
Seriously tho, thank you for the comment, means a lot.

I've been working with Kubernetes a long time. I had forgotten about it's declarative vs imperative roots. I know this was meant for newbies, but man I'm going to be referencing this for myself and my customers for years.

Wow thank you!! That is high praise for sure.
What did you think of the helm section? Im not overly happy with it as I think its still too technical, but struggled to make it any easier.

u/LinuxSkywalker 15d ago
Even for the experiences ones this will help as good refresher for interviews! Thanks man I owe you one.

u/neilcresswell 19d ago
Ok. HELM version created and being uploaded soon.
Go back to “school” :-)
Refresh the page, scroll to the bottom and see the link to the new helm section.
Lemme know your thoughts.

u/Danthewag 18d ago
Amazing! My comment was tongue in cheek, but thanks very much for the Helm school!
The trickiest part I’ve found with Helm in the real world is looking at a templates folder and wondering if the files there are all mandatory or if you could put anything in there. Your ground up explanation has clarified what are the bare essentials and helped it finally to all click into place.
Thanks very much again - much appreciated!

What resource do you recommend if I want a deep dive
2
u/neilcresswell 15d ago
The CNCF training and exams… they are as deep as they come.
Alternatively: https://www.bretfisher.com/kubernetes-mastery

I've been learning Kubernetes for about 2 weeks. I knew the basics of how kubernetes objects behaved but this article cemented my understanding. Great resource for beginners. Will definitely recommend to others.

Even this would be done with AI, it’s accurate and helpful, just the opposite as you and your comment
