- Kubernetes Deconstructed: Understanding Kubernetes by Breaking It Down [I] - Carson Anderson, DOMO
Understanding Kubernetes as a whole can be daunting. With so many different components working together it can be hard to know how the pieces work together or where new products and features fit in. I will start at the highest level and then peel off the layers one at time to explain how some of the "magic" happens. Over the course of the presentation I will break Kubernetes into the following layers:
"Kubernetes for the End User": A quick summary on some of the core components of Kubernetes: Namespaces, Deployments, Pods, Services, and Ingress Rules. At this layer the user just needs to understand the promises made by Kubernetes, not necessarily the way it keeps them. This layer primarily serves to establish a typical cluster workload. The resources defined here will be used when explaining all of the deeper layers.
"Kubernetes for the Cluster Admin": This Layer peels away some of the cluster "Magic". I will cover how the service account, default tokens, ReplicaSet and Pods from the previous layer got created by the kube-controller-manager. I will also explain how the kube-scheduler decided which node the workload should run on and how that decision could have been influenced by fields in the pod spec. This section will touch on the core concepts of Ingress controllers, Admission Controllers, scheduling, and core controller loops.
"Kubernetes for the Cloud Admin": This layer covers Kubernetes at an infrastructure level. Core concepts covered are: Horizontal Scaling, Load Balancing, high availability for masters and nodes, node management, and fault-tolerance levels. Here is also where I set the stage for the network layer that is covered next.
"Kubernetes for the Network Admin": Now we dig deeper into the network infrastructure. Explaining how pods and services work together, how your network traffic figures out where to go, and how it gets there. This section covers the concepts of East-West and North-South load balancing. The goal is to provide an basic understanding of the network promises made by Kubernetes and how you might replace them with other software and services.
"Kubernetes for the Linux Admin": A discussion of Kubernetes at the OS layer. This layer digs into the processes and configuration of the base OS. This includes pluggable container engines ex: Docker vs. Rkt, logging, CNI, metric gathering and volume mounting.
"Kubernetes for the Power-User": Time permitting, the final section will put all of the previous ones together to show how a next-generation application might be deployed on top of Kubernetes and take advantage of the more advanced features.

I was about to comment the exact same thing
Or... drink so much coffee and energy drinks that you match his level of energy and time slows around you...
Everything explained perfectly in so little time! Incredible. drop the cameraman.
The best video I've ever seen so far describing almost all Kubernetes components in just 30 minutes. Brilliant!
except some of the bad video making skills
Hehehe! Naprawde? Przeciez gostek sypnął milionem do niczego nie potrzebnych naglowkow I faktycznie niczego nie powiedzial
One of the best sessions at KubeCon 2017, thanks!
Best explanation ever! In just 30 minutes, that’s awesome! Thank you!
Really good presentation that teaches a lot of the core plumbing. Clear explanations and good diagrams/animations.
This should be a master class series..
Thank you for respecting my time and diving straight in :) great video
Totally the best explanation of Kubernetes component on the net
Amazing talk, thank you very much!
Amazing explanations. Great work!
Really amazing, it is putting almost all concepts in just 30 mins.
Clean and neat presentation with an elegant content.
Nice one , thanks .
Brilliant video! Great work!
Very comprehensive, simple and easy to understand, thank you
That is a very slick presentation. 10/10
By far the best kubernetes deep dive talk I've seen! The full version on Vimeo is even better. Congrats!
Very well laid out graphically and using animation to describes concepts. Well done!
This was what I needed!, I was wondering how everything communicated with one another
awesome talk you made!!!
Very nice presentation, thank you
well explained in a oversight!
My God, does he talk fast! A great presentation, very well planned and executed.
This is awesome! It's really helped me understanding what's beyond creating pods/services :) Thanks!
Lean and concise! Thank you
Amazing! I'd recommend to watch at 0.75x n pause along to absorb each concept.
Dude, you did it really good ;)
Really well done talk. Awesome slides
Awesome explanation
It is a good video, thank Carson Anderson and CNCF
brilliant !
Great video
Outstanding
Good presentation!!!
For someone spent the last two weeks drowning in k8s documentation, this is a lifesaver, even in a post-drowning way. k8s official documentation really lacks this kind of overview introduction, it goes into details bit too much IMO.
Hi, great presentation! I have been coming back and listen to it again and again. Could you please share how and what tool did you use to auto type the commands? Thanks much!
Good job.
set to speed 0.75 and you can follow him really good. ;) excellent presentation !
I've set it to 2 and almost fell asleep.
😂
You are right. It is good to read the comments before watching :)
Nice 👍
Thanks
nice talk
Why do they move the camera at 21:42? It was so clear before - both Carson and the screen.
The camera operator came back from a long brake, and needed to do somethings to make it look like they are busy and necessary.
whoever filmed this, didn't have a clue; was probably used with zooming on boobs
oh ma bad, I see he changed to a split screen afterwards, I take it back:P
I watched this video 2x speed, ‘cause he speaks sooo slowly.. almost got myself sleeping 😀
Awesome talk but the cameraman ruined moving the camera off the slides.
note to the camera guy, people want to look at the slides -- not the presenter. The slides are kind of important to follow along.
"making it real" - Carson Anderson
This is helpful .. however I found it bit fast.
what presentation tool is he using!??
Clement Duval sozi, he mentions it at the end.
Does any body has an idea which tool is used to create such good slides ?
@livestupid thinkbrilliant I use Linux. So power point is not available ;)
He used Sozi, see the start of the credits at about 31:47. Link: sozi.baierouge.fr/
CaRSOn how do I [or anmyone else] install Kubernetes anyway?
@21:50 - the screen, show the screen.....
Awesome video but stop cutting away from the slides
I just see concept, without knowing the underlying things, maybe that's too complex for a single video.
is he typing that fast in the beginning ??
It’s auto-typed. He mentions it.
Amazing explanation, camera man awful 😂
had to doublecheck the video playback speed, because he talks really fast :D
Not for beginners
Great content ,worst cameraman ever..
Great talk... noob camera handler :) Next time better!
A lot of good knowledge but he was talking too fast
Too fast for my old lazy brain
