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

Learn more about Kubernetes → ibm.biz/BdPMfd
Check out IBM Cloud Kubernetes Service → ibm.biz/BdPMfD
Although it is a common misconception, Kubernetes and Docker are not opposing technologies. In fact, they actually complement one another. Moving to scale with Docker alone poses many challenges, and Kubernetes tackles those challenges that emerge with large Docker-based deployments.
In this lightboarding video, Sai Vennam goes through the misconceptions around the Kubernetes vs. Docker question and outlines the key advantages of Docker and Kubernetes when used together.

I love your way to explain with complex technologies to be simple and easy to understand.

[@fisouz]

You're a very good presenter. Make the most out of it!

[@IBMTechnology]

Hi Filipi, thanks for the reply. Yes Sai is a great presenter and we have another one coming out featuring him soon.

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

[@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 very much for watching! 💙

[@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.

[@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.

[@visorescolector]

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?

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?

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.

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

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

Awesome Thanks!

[@lusiek21]

CRI-O is a default container runtime for Kubernetes

[@qubit6787]

Are there other language that can access the database in your cloud native application schema here?

[@suyogdahal8185]

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.

[@IBMTechnology]

Hi Suyog! Kubernetes doesn't use docker-compose files, but to answer your question, yes those are reserved properties. --Sai
