Thank you! This lesson helped me understand that Kubernetes and Docker aren't necessarily competitors, but work, when need be, perfectly together, bringing out the best features in each other. You explained really well.
Great video; I really enjoyed it, but the question isn't Kubernetes VS. Docker (not comparable in that manner, as you said yourself) but rather Kubernetes VS. Docker Swarm.
Hi Max, thanks for watching and your comment! While we don't have a video on the subject (yet), Kubernetes vs. Docker Swarm is absolutely an important discussion. We've covered it here: www.ibm.com/blogs/bluemix/2018/10/docker-swarm-vs-kubernetes-a-comparison/
The things you explained like if one node goes down then it'll automatically restart it. I believe these features are already there in Docker Swarm. I do agree that Kubernetes has some extra features though.
If we are going to use Containers (any kind, including Docker) the OS is - by default - going to be Red Hat Enterprise Linux or one of its derivatives. Yes, Ubuntu MAY be used. But, it is nowhere near default !
I am very grateful for this education. I like that IBM is doing these simple lessons that you clearly understand well for those new to the industry. Thank you
Hi! This video focuses on the open-source project Kubernetes -- not strictly the IBM or Red Hat approach 🙂 . Ubuntu is still the more commonly used OS for running Kubernetes.--Sai
Is Kubernetes can scale Vertically or Horizontally ? Is that Auto scaling can be done via a Load balancer externally by a Public loud services like Azure , AWS etc ? Please share your inputs .
newbie on this, I have my Mac Catalina in a VM, in order to learn the basics, should I use K8 or simply Docker? And the main question, what apps deployment should I deploy and install in order to try it out with a simple example?
Hi @Sai Vennam, thanks for sharing consolidated understanding. I have the following questions.. 1. where will Kubernetes be in the tech stack you drew at right (your right) 2. Where will Kubernetes place the application, application will sit on individual worker or will it be across workers? pls respond .
Hello Jyothi: Here's a post we wrote to explain how these videos are created. ua-cam.com/channels/KWaEZ-_VweaEx1j62do_vQ.htmlcommunity?lb=Ugzf5SL_yh9NglCJzgF4AaABCQ Let us know if you have any more questions and thanks for visiting.
Hi Hamza, thank you for the question! To name a few, besides Java™, there's also C++, VB .NET, and other .NET languages, COBOL, Fortran, PHP, Python, REXX, or Ruby. You can access some resources about database programming here: ibm.co/3ez92kK
I started thinking the same thing, then it occurred to me that they could have just mirrored the video in edit. As he's writing with his left hand, that's probable. Great video production either way.
Hello Pankaj! It would be running per os instance. Small clarification - Kubernetes has moved to using containerd rather than a Docker-based runtime. Thank you for watching, Sai
hey guys, could you please explain to me the main difference between Data Retrieval and Out bound prices? If I only want to use the object storage as a archive repository for backup, what of the two fees should I consider?
Actually this video presented in great manner. But here title said Docker vs Kubernetes and it should be "Docker deals with containers and runtime for containers.. "Kubernetes deals with managing containers manage containers - auto scale etc... How did you make this video? How were you able to write on boxes? Please tell tech for that..
I love how everyone always says, 'they aren't competing technologies," use both of course but then in the end they say, "if you're starting out and expect to scale use K8s" or "if you are already using Docker it'll help tackle operations overhead." So...use K8s. Also, you're saying if you want your business to fail don't get K8s. Aren't all businesses required to grow in order to stay alive? Also, there seems to be no use case for using Docker to run the application in production.
@ralienpp I'm not certain but I think, he was behind a glass and the camera was recording from the other side. In post production, they just mirrored the video in the editing app.
Hey @ralienpp, thanks for the question and glad you liked it! We built a lightboard setup that has the presenter behind the glass (which is lit up by LED lights in the frame of the board). The presenter diagrams out the solution, and then we flip it in post-production. We've done 2-3 others like it (and have more planned), and we're loving how they are turning out!
@@tejaskhajanchee1086 Glad there is so much interest in this and thank you for the question! We have more like this in the works. @Tejas, he writes as normal on his side of the lightboard and then we just flip it in post-production. Hope this helps!
Hi there! Check out this video 👉 ibm.co/3CcmAvz And the Kubernetes playlist on our channel 👉 ibm.co/3CjRQbM Also, check out the links in this video's description, they lead to more Kubernetes basic information. ⤴️ Hope this is what you needed! 🙂
Hi! You're right, I should have phrased it differently. By allowing developers to take advantage of built in service discovery (service names for your containers), config and secret management, and automatic load balancing, it allows developers to focus on application code. They don't have to worry about instrumenting their code to call other microservices; they can just use the service names. In my experience, this has made development much easier!
Are the property and the keywords such as services, build, ports etc in docker-compose yml file reserved keywords or can we change it to other names aswell.
Good morning Handa: Here's a post we wrote to explain how these videos are created. ua-cam.com/channels/KWaEZ-_VweaEx1j62do_vQ.htmlcommunity?lb=Ugzf5SL_yh9NglCJzgF4AaABCQ We appreciate you watching our videos.
I love your way to explain with complex technologies to be simple and easy to understand.
You're a very good presenter. Make the most out of it!
Hi Filipi, thanks for the reply. Yes Sai is a great presenter and we have another one coming out featuring him soon.
Thank you! This lesson helped me understand that Kubernetes and Docker aren't necessarily competitors, but work, when need be, perfectly together, bringing out the best features in each other.
You explained really well.
Thanks for the feedback, Maithri! 😀
In addition, love how he writes backwards so effortlessly!!
Yeah I was just thinking how is nobody impressed by this😂
He is flipping the video.
Lol. He is using lightboard technology. He is writing on glass. In post-processing stage it's flipped horizontally.
Notice buttons on shirt, now look at your buttons……..
Please do more videos! You're really great at presenting complex tech!
Indeed!
IBM please promote this guys.....he just rock.....
What a great presenter Sai is !
Great video; I really enjoyed it,
but the question isn't Kubernetes VS. Docker (not comparable in that manner, as you said yourself) but rather Kubernetes VS. Docker Swarm.
agreed.. published on oct 16, 2018? swarm should be compared not just a docker host.
Hi Max, thanks for watching and your comment! While we don't have a video on the subject (yet), Kubernetes vs. Docker Swarm is absolutely an important discussion. We've covered it here: www.ibm.com/blogs/bluemix/2018/10/docker-swarm-vs-kubernetes-a-comparison/
@@IBMTechnology Thank you for the link to the Article, it's a really good read!
K8s vs Docker should not even be asked
@@lexterikane It's actually asked by people who don't really get what they are about. This video mostly clears the confusion.
no doubt, this video cleared basic difference of docker and k8s. Thanks Sai for the wonderful video.
I don't usually find this about a lot of videos, even IBM videos ... this was EXCELLENT. nice job young man!
I love the way he puts it, and while being so calm. Really informative
The things you explained like if one node goes down then it'll automatically restart it. I believe these features are already there in Docker Swarm. I do agree that Kubernetes has some extra features though.
Valuable videos always have something special.
This cleared up a lot of confusion for me. Thank you
2020 update, you don't need ubuntu to run docker, and React runs on client brower, (unless it's a next.js or gatsby which is server side render)
Hi Sai, what service/tool you're using for white boarding?...Amazing presentation greatly simplified. My students loved it
it is only now that i understand kubernetes completely. thank you sir
Another great explanation. Your videos are binge-worthy!! Thank you Sai!
Thank you very much for watching! 💙
Thank you very much Sai, this is the first video where Kubernetes clicked for me. Keep it up!
We're happy that this video was helpful to you, Matt! Thank you!
If we are going to use Containers (any kind, including Docker) the OS is - by default - going to be Red Hat Enterprise Linux or one of its derivatives.
Yes, Ubuntu MAY be used. But, it is nowhere near default !
Can you explain why this is?
Great video and I'm just wondering how he writes on the screen with nothing between him and the camera?
It's filmed through a glass pane and the image reversed in post-production.
I am very grateful for this education. I like that IBM is doing these simple lessons that you clearly understand well for those new to the industry. Thank you
You mentioned the OS is usually Ubuntu. Wouldn't it be Red Hat? Especially since IBM acquired Red Hat.
lol, good point
Hi! This video focuses on the open-source project Kubernetes -- not strictly the IBM or Red Hat approach 🙂 . Ubuntu is still the more commonly used OS for running Kubernetes.--Sai
Your single sentence explanation cleared up so much for me. Thank you 🙏
Is one worker box same as one deployment box?
Is Kubernetes can scale Vertically or Horizontally ? Is that Auto scaling can be done via a Load balancer externally by a Public loud services like Azure , AWS etc ? Please share your inputs .
Great job and explanation. I just subbed to IBM because of this vid
Just love these videos. I am really loving these videos. Thank you for sharing
Great presentation and whiteboard..
well explained, straight to the point, now I understand the difference between docker and kubernetes
newbie on this, I have my Mac Catalina in a VM, in order to learn the basics, should I use K8 or simply Docker? And the main question, what apps deployment should I deploy and install in order to try it out with a simple example?
Short, Clear and Precise!! Excellent Presentation #sai
How do I do this lighboarding presentation? Is there any app that you would recommend? Thanks in advance.
This video was very clarifying: thank you so much. IBM will be IBM...
Hi @Sai Vennam, thanks for sharing consolidated understanding. I have the following questions.. 1. where will Kubernetes be in the tech stack you drew at right (your right) 2. Where will Kubernetes place the application, application will sit on individual worker or will it be across workers? pls respond .
T insukia. At2015. 09 sep. 2015
Can anyone help to explain what does it mean by ‘moving to scale’, does it mean the app or system grows up to a certain high level or scale? Thanks!
Awesome video, one question, how do you draw between you and the camera? what tools are you using?
The speaker writes on the glass as normal, then the video editor flips it around in post production. Thanks for watching!
@@IBMTechnology Can you guys please tell us a little more about this technology, a tutorial perhaps or the makers of this technology?
What do u mean by spin up containers
Can you have redundant k8 masters if the primary fails?
What tool did you use to make it look like you are writing behind your drawing?
Hey Terrie! We wrote a post to explain how we make these videos here: ibm.co/2SA1vGd Thank you for visiting our channel.
This transparent board is amazing, wonder how did he do it? Writing on a glass?
Hey there! Here is a blog post we wrote that explains how we do it. ➞ ibm.co/30TGdZm
Can anyone explain what CNI is in layman's terms.
Hey what Is the role of operation (infra engineer) role what is the career path to learn cloud native technology.
is this no longer the best way since kubernetes is now a full container service with integrated storage and vm servers through google cloud?
Awesome presentation🤩.
Had to watch the video twice.
The first time I got lost if he was writing RTL or LTR 🤓
nice video and easily understand, I have a question may I know which board using to explain

@@craigheckrath5349 That's correct, post-production mirror flip
Very good post. One question: can the Docker deamon run across multiple machines? Or, one docker deamon per os instance?
Hello Pankaj! It would be running per os instance. Small clarification - Kubernetes has moved to using containerd rather than a Docker-based runtime. Thank you for watching, Sai
Are there other language that can access the database in your
cloud native application schema here?
Thank you Sai, you are the man

Isnt node.js directly talks to database?? Why java again??
Thanks for making this easy for us to understand!
can I ask how do they make these videos? is there any special software for this?
Another wonderful session
Thanks for the video IBM!
You're welcome, thanks for watching!
How to make video like that, writing directly. Like writing on mirror
Actually this video presented in great manner. But here title said Docker vs Kubernetes and it should be
"Docker deals with containers and runtime for containers..
"Kubernetes deals with managing containers
manage containers - auto scale etc...
How did you make this video? How were you able to write on boxes? Please tell tech for that..

please help us Sai
Hi Kamaraj. Here is a blog post we wrote that explains the writing style. ➞ ibm.co/2LTPMjo
Thanks for the presentation. How did you create the ”writing on a transparent whiteboard” effect?
@ralienpp I'm not certain but I think, he was behind a glass and the camera was recording from the other side. In post production, they just mirrored the video in the editing app.

@6:35 - Kubernetes services has made development easier? How? This is configuration management, not development.

How do u write backwards fast??
See ibm.biz/write-backwards
Great presentation and concise.
Docker containers make sense but 'Kubernetes boxes' isn't a formal definition and renaming the 'boxes' to 'worker nodes' is vague and abstract.
Where and how do you learn all these things about app deployment? Can you recommed a book or a course? :)
look up abt devops, docker, take a random app and deploy it locally, it can help
