Hey Everyone, can you let us know in the comments what topics or types of videos you'd like to see on our channel in the future? Your feedback is greatly appreciated. Thank you!
I like these bite-sized videos giving us a high level overview. It makes me feel like I can participate in discussions where the topics you cover are brought up.
This video was perfect for a quick high level overview of k8s, including even explaining what the acronym means. :) Great diagrams, very clear and concise speaking.
I am new to this hidden gem, probably to me alone. Your contents are so easy to understand. I have gone through many videos on K8s on YT and never ever I got satisfied or convinced with the explanations but this. Loved the simplicity of both oral and pictorial delineation of the concepts.
I run docker inside kubernetes on an Alma VM in qemu on an Ubuntu server VM under hyper-v on a Windows workstation. No work actually gets done, but boy does it look busy!
The introduction reminds me of: The other day my daughter sidled into my office and asked me, “dearest father”, whose knowledge is incomparable, “what is Kubernetes”? Right, that’s a little bit of a paraphrase but you get the idea, and I responded, "Kubernetes is an open source orchestration system for docker containers. It handles scheduling onto nodes in a compute cluster and actively manages workloads to ensure that their state matches the user’s declared intensions. Using the concept of labels and pods, it groups the containers which make up an application into logical units for easy management and discovery" And my daughter said to me huh
There is another component called CNI (container network interface) that provides networking in k8s. Some popular CNIs like Cilium, calico has the capability to replace kube-proxy. So, kube-proxy is not a mandatory component.
K8s is a collection of services at the end. You can repalce many parts of it including store, scheduler, controller, container runtime. CNCF maintains base spec, and implementation would vary from vendor to vendor. That's why you have k3s, rancher, docker kubernetes, redhat openshift, and cloud implementations of gke, eks, and aks as control planes. It's the same as having a spec of java but having so many impmentation of jvm. Or having ECMA specs and different impmentation in form of v8, spider monkey, jscore etc.
CNI CSI CRI are just kubernetes interfaces, They are not kubernetes components. companied can make network plugin to implement CNI to work with kubernetes.
i think this is the best video so far to give a highlevel understanding. there are lots of tutorials in which professors have no idea what they are doing.
This is one of the nicest well-made tutorials I've ever seen cool animations to keep us focused deep voice to stay concentrated and pure knowledge thank you man
Great video! Not sure that it can be considered as a typo but at 2:31 there is a diagram with arrows from CM, Scheduler and API Server to etcd, but in fact the ONLY API server interacts with etcd directly, other components interact with etcd through API Server. Thanks.
Love the recommendation at the end. YAGNI! I should have told my org leaders a few years ago, but now it’s too late: after years of preparation it’s ready for production…
Kubernetes comes from the transliteration of the Greek word "Κυβερνήτης" which means commander, captain (of a ship), a person who has the control of something (e.g. a vessel).
another option is to use serverless managed container service like cloud-run which is behind the sense kubernetes cluster, it's easer and faster for startups and also cost effective "pay as you go"
Slight correction here: "Docker Swarm: Docker Swarm does support secrets, including TLS secrets. However, the management and integration of secrets in Docker Swarm are relatively basic compared to Kubernetes. In Docker Swarm, secrets are stored in the Swarm manager and distributed to nodes as needed. Kubernetes: Kubernetes has a more comprehensive and flexible secrets management system. Secrets in Kubernetes can be managed through Secrets objects, and they can be encrypted at rest and accessed by containers in a more fine-grained manner."
This is the epitome of excellence. I recently enjoyed a similar book, and it was the epitome of excellence. "Mastering AWS: A Software Engineers Guide" by Nathan Vale
kinda like shipping and receiving if you've ever worked in a physical warehouse. Bulk product comes in from external source -> it needs to be individually palletized first, then when customer "demands" the product (similar to increase in Kubernetes load increase) -> individual pallets are built and shipped out by "workers" .. i.e. Kubernetes containers. or something similar.
Getting a small cluster up and running was a real pain. Once all the housekeeping is taken care of, it seems much easier than for instance Docker swarm. However, what I really dislike is what is necessary to have persistent storage in a localized cluster that is not using storage from Amazon, Google etc.
Great way of explaining, my school always made it difficult to understand the basic of k8s. But now thanks to this video everything is more clear to me! Also the animations were very helpful.
love the simple explanation above all i love the presentation also .. can author or someone please tell me which tool is used to make these kind of presentations plz.
I'm learning kubernetes, and this video is great to consolidate my knowledge. So what is the alternative for small organizations , which tools would you use ?
I would recommend nomad. I'm completely in the kubernetes universe (big Corp), but a friend of mine is using nomad in production(mid sized company). We both used swarm before and would not go back.
@@stefanriembauer9337 thanks but what about a very low server resources like 2gb ram server to install wordpress or a small server, would you install this ?
Thank you for this very simple and clear explanation. There are everything need to make it very easy to understand. Having you as a teacher will be very good opportunity to learn in a very simpliest way. Keep on the good job. Could you provide us with a very simple tutorial on K8s, now that you have given us an overview of the topic. I think it will good to move to a hands on a demo tutorial.
@@bjornvandijkman1225 This question gets asked about half a dozen times on every video in this channel. In about 10% of the questions someone does post the answer, but I forgot the name of the tool.
I think the best piece of advice you gave is “overkill for small organizations”. Like there’s so much hype around it, people think they can just install k8s and have it solve all their problems. In order to use k8s successfully you need to understand exactly the shortcomings of your existing setup, and how k8s would address those shortcomings. 90% of the time, by the time you actually understand your shortcomings, you’ll have amassed a giant list of things you can improve. Chances are, your small company’s servers aren’t doing enough to justify scaling things like Google.
Hi sir, thank you so much for the fantastic videos from which we've learned a lot in an easier way. I'm curious with what tool you make the video with moving architecture diagram components.
Great to see your video.We are seeking a highly skilled and motivated Architects/Senior engineers strongly experienced with multi K8s(Kubernetes) cluster management on Baremetal in data centers /on-premises/with cloud providers like Azure or AWS for part time assignment(remote opportunity). Should be strong in Custer API. The ideal candidate will have a strong background in the mentioned areas with 10+ years of experience and end to end experience. The resource needs to have experience in · CAPI · Helm · Argocd · metalLB · isthio ingres controller · Kubeadm · Security storage & networking with Calico Th architect is expected to make architecture and documentation of proposals and prepare POC as and when needed. The expected weekly hours would be 10-15 hours per week. If interested kindly let me know.Thank you.

It is like Fireship but without memes
My thoughts, exactly!
imagine being that person lmao yikers
No its better, its not in 100 seconds, but in 300 :D
ByteByteGo explainers are way better than Fireship when it comes to system design. Appreciate both for their relative strengths.
It’s wayy better than fireship
Sir, I am from India
I learned so much from your vides that I could not learn in last 10 years.
Respect to you 師父🙏
Hands down one of the greatest Computer Science channels of all time!
Beautifully animated, clear and easy to understand. Keep it up.

You should make a video
Absolutely technical yet easy to understand! Your videos give me a lot of confidence. Thank you 🙏

@@BohonChina too bad most people just fed this guy's knowitall ego and did not check these comments
I actually watched the video with 1,5x times speed so it actually took even less time. Thanks much for the overview.
Thank you, I went from zero knowledge to understanding a little about k8s, even learnt what k8s was short for. Great video!
i think this is the best video so far to give a highlevel understanding. there are lots of tutorials in which professors have no idea what they are doing.
Great video, you can't get a better overview of K8s in 6 Mins 🙂😍
Love the graphics quality. Love how he films this from a closet. Great videos.
I hope you would make noob friendly/introductory videos in the future. I like watching your videos even though I can't understand everything.
This is one of the best and easy to understand videos on kubernetes topic. Good job!
This is one of the nicest well-made tutorials I've ever seen cool animations to keep us focused deep voice to stay concentrated and pure knowledge thank you man
Excellent. It tend to say: YAGNI applies in 90 percent of the cases.
Nice overview - helped me understand the various parts, thank you!
Great video! Not sure that it can be considered as a typo but at 2:31 there is a diagram with arrows from CM, Scheduler and API Server to etcd, but in fact the ONLY API server interacts with etcd directly, other components interact with etcd through API Server. Thanks.
Yes true..
I too observed that.
In the picture, shown like all components communicate with ETCD, whereas only API server communicates with ETCD
One of the best k8s overview!!!
Love the recommendation at the end. YAGNI! I should have told my org leaders a few years ago, but now it’s too late: after years of preparation it’s ready for production…
What a video of great quality, this was synthetic, visual and well explained. Thank you for the hard work !
Guys your videos are magical, delivering the most complicated ideas in the simplest and the best way! thank you so much!!!!!
Kubernetes comes from the transliteration of the Greek word "Κυβερνήτης" which means commander, captain (of a ship), a person who has the control of something (e.g. a vessel).
I just discovered this channel, the content is really amazing, it's concise and clear
best overall video on the matter, top content as always.
YAGNI ... new word ! I will use it !
What if YAGN YAGNI though?
I love this type of content, let me know if you’ll be interested in expanding it to another language (my native language is spanish).
another option is to use serverless managed container service like cloud-run which is behind the sense kubernetes cluster, it's easer and faster for startups and also cost effective "pay as you go"
Yes, really, this is one of the easy-to-understand videos on Kubernetes topic.
First time clearly understood what is K8S saw so many videos but this is the best :)
the animation and the effort put into this video is too good. great explanation.

man, that was my perfect 6 minutes spent! thank you
love this channel man, keep going!
Hi, thanks so much! One moment is that kubeproxy manages iptables. It's not a classic proxy.
Getting a small cluster up and running was a real pain. Once all the housekeeping is taken care of, it seems much easier than for instance Docker swarm. However, what I really dislike is what is necessary to have persistent storage in a localized cluster that is not using storage from Amazon, Google etc.
Great way of explaining, my school always made it difficult to understand the basic of k8s. But now thanks to this video everything is more clear to me!
Also the animations were very helpful.
Wonderful presentations, when technical complex topic is presented into a beautiful simplified one. Thanks so much !!!
Really good start for a beginner ❤️
Excellent Video. Short, crisp and too the point. Thanks for your efforts.
Awsome explanation, it was fast and easy to learn, I was with a lot of doubts, Thanks for sharing in a simple way your knowledge!
Great explanation, information and video.
love the simple explanation above all i love the presentation also .. can author or someone please tell me which tool is used to make these kind of presentations plz.
Another great video explaining the complex architecture in a detailed presentation. Thank you.
It is one of the best and short class with detailed information. The way of explanation is excellent. Thanks a lot !
These videos follow the same philosophy of the books. Superb
Thought it would be dry but U enjoyed it. Little dosage of information was awesome
This is a great video to get a high level overview of kubernetes. Thanks!
What an amazing visualization animation effect!
Great.. Explain a lot in simple way and in short time
I’m not sure it’s somehow possible to better explain what k8s is about in 8 mins. Thank you very much!
This is a amazing video to explain how does Kubernetes work. Could you please explain the Docker?
which software are you using for videos? they are perfect
This is amazing. The depth of the explanation was exactly what I wanted and needed. Thank you!
excellent , Very Precise . Sir where do u create such awesome Architecture Diagram??
hey thats a pretty good video you are a good narrator
Happy Wednesday,
I did learn something new
YAGNI
🤣🤣🤣
I'm learning kubernetes, and this video is great to consolidate my knowledge.
So what is the alternative for small organizations , which tools would you use ?
I would recommend nomad. I'm completely in the kubernetes universe (big Corp), but a friend of mine is using nomad in production(mid sized company). We both used swarm before and would not go back.
@@stefanriembauer9337 thanks but what about a very low server resources like 2gb ram server to install wordpress or a small server, would you install this ?
amazon ecs can be considered. comes with no frills, less complexity and management overheads.
For faas like functionality look at SAPs Kyma project :)
Thank you for this very simple and clear explanation. There are everything need to make it very easy to understand. Having you as a teacher will be very good opportunity to learn in a very simpliest way.
Keep on the good job.
Could you provide us with a very simple tutorial on K8s, now that you have given us an overview of the topic. I think it will good to move to a hands on a demo tutorial.
Awesome as usual👍, can you please talk about K8s clusters replication and Disaster recovery!
Great insights as always, just a question, what tools do you use for your animations?
It's 2023 and nice graphics with animations are no longer an anomaly. There are plenty of packages out there for sprucing up your presentations.
@@DemPilafian Also curious about this, would you mind naming an example that can achieve this?
@@bjornvandijkman1225 This question gets asked about half a dozen times on every video in this channel. In about 10% of the questions someone does post the answer, but I forgot the name of the tool.
If i remember correctly it is adobe after effect.
when in doubt, it's usually After Effects
I think the best piece of advice you gave is “overkill for small organizations”. Like there’s so much hype around it, people think they can just install k8s and have it solve all their problems.

ecs is a good alternative with reduced complexity.
Wonderfull pin point 👉, small still full of information. 👍👍
It so useful, but very fast to too complex subject.
Anyway, congratulations!
This is a fantastic video. Thanks a lot for all your efforts to create this video.
You earned a subscription!
Very nice video , thank you very much for this content.
Wow, amazing job explaining all that in such a succinct (but very clear) way! Can I ask what software you use for the diagrams and animations?
simple words explain something complexity
animation so so educatif and ergononic and beautiful ( how do you do ? :)
thanks from France !
Thank you very clear, precise and to the point.
I like the short animations, great video series
Isn't docker swarm a simpler solution for small/midsized companies?
Nicely animated with useful stuff to understand the technology.
Hi sir, thank you so much for the fantastic videos from which we've learned a lot in an easier way.
I'm curious with what tool you make the video with moving architecture diagram components.
Can you make a video on Hadoop, Yarn and Pyspark?
Thank you, it was helpful!
There is an error in the video - etcd is only used by API server, nothing else.
Really Nice video and explanation is vry good. Thankyou team.

Excellent Video and amazing animation skills !
Very informative and precise, thanks.
I like the presentation. What application is used?
Thank you very much for this amazing video.
YAGNI - haha that killed me at the end. :-D
Are you able to recommend what smaller organisations can use? I don't think that saying "YANGI" is enough or appropriate
Your animation are pretty nice. What tools do you use for this
you are a GEM man, what do you use for your animations ?
YAGNI is always a very important option to consider...
Fantastic, so instructive, I wonder if you wouldn't mind to do a deep full tutorial of yagtni, is necessary for my level of expertise,
Thank you! fantastic video. Great info and concise!
greate summary. ❤. what is the tool used for the animations ?
Very useful . Thank you.
I would like to see a video about an Alert processing streaming system design.
