Kubernetes vs. Docker: It's Not an Either/Or Question

[@maxkossatz7926]

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.

[@r0tt13]

agreed.. published on oct 16, 2018? swarm should be compared not just a docker host.

[@IBMTechnology]

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!

[@exuperokouya5788]

K8s vs Docker should not even be asked

[@IoNoobMaster]

@@exuperokouya5788 It's actually asked by people who don't really get what they are about. This video mostly clears the confusion.

[@fisouz]

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.

Yeah I was just thinking how is nobody impressed by this😂

[@maithreshpalemkota8840]

He is flipping the video.

[@deepakvijayakumar7112]

Lol. He is using lightboard technology. He is writing on glass. In post-processing stage it's flipped horizontally.

[@maithriashokan]

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.

[@IBMTechnology]

Thanks for the feedback, Maithri! 😀

[@Singh12]

What a great presenter Sai is !

[@RaymondPeckIII]

I'm really impressed by his ability to write backwards. 🙂

[@IBMTechnology]

Search on "lightboard videos" to see how they're made.

[@paulzikopoulos713]

I don't usually find this about a lot of videos, even IBM videos ... this was EXCELLENT. nice job young man!

[@olaade730]

I love the way he puts it, and while being so calm. Really informative

[@durgaprasadbehera9916]

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.

[@severtone263]

This cleared up a lot of confusion for me. Thank you

Hi Sai, what service/tool you're using for white boarding?...Amazing presentation greatly simplified. My students loved it

[@usnoozeyuloosey]

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

Another great explanation. Your videos are binge-worthy!! Thank you Sai!

[@IBMTechnology]

Thank you very much for watching! 💙

[@DanielDumitriu]

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 !

[@lmobjr2086]

Can you explain why this is?

[@TheJFMR]

well explained, straight to the point, now I understand the difference between docker and kubernetes

[@vikrama736]

Short, Clear and Precise!! Excellent Presentation #sai

Great job and explanation. I just subbed to IBM because of this vid

[@falconheavy595]

Thank you Sai, you are the man

[@NoOne-yp1qe]

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.

[@scottylans]

I'm wanting to learn this stuff and this video was very informative, thank you.

[@pramodjingade6581]

Awesome presentation🤩. Had to watch the video twice. The first time I got lost if he was writing RTL or LTR 🤓

[@Garejoor]

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)

[@gm130s]

Very helpful! That said, I still don't get if using Kubernetes without Docker makes sense (I'm newbie to Kubernetes)

[@TheSaucererLadle]

kudos for great mirror writing skills

[@nijnij3988]

Great video! Really, you're an amazing teacher. Thank you!

[@HazemTamimi]

I just started watching the videos. Small note: Are you writing in a mirrored way??

[@craigheckrath5349]

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.

[@riti_chrea]

@@craigheckrath5349 That's correct, post-production mirror flip

[@kidacrimson1204]

[@xavierprudent6963]

This guy is very good.

[@JohnLee-jj1bg]

Great video and I'm just wondering how he writes on the screen with nothing between him and the camera?

[@IBMTechnology]

It's filmed through a glass pane and the image reversed in post-production.

[@eldwinc9884]

In other words, Kubernetes builds on top of Docker. What ppl need to know is that the either-or scenario applies to Docker Swarm vs. Kubernetes

The speaker writes on the glass as normal, then the video editor flips it around in post production. Thanks for watching!

[@mateenezzat86]

@@IBMTechnology Can you guys please tell us a little more about this technology, a tutorial perhaps or the makers of this technology?

[@robertkerr229]

That's some skill -- writing correctly from behind the glassboard!

[@IBMTechnology]

See ibm.biz/write-backwards for the backstory

[@Trazynn]

Docker containers make sense but 'Kubernetes boxes' isn't a formal definition and renaming the 'boxes' to 'worker nodes' is vague and abstract.

Hey there, Andhra! This is how he create these type of videos: ibm.co/2VCsraj 😃

[@edbouhl3100]

When you consider what is happening at an atomic level, it’s amazing any of this actually works! And if AIs do start writing their own improved code that can take better advantage of the atomic level mechanics , it won’t take long until we have no idea how any of it works. And at that point, magic will have appeared in the world.

[@RedMageGaming]

Just because we know how it works now doesnt make it any less magic.

Kubernetes is great. But, in your example, can't you just setup a Docker Swarm?
