Kubernetes
Kubernetes is the de facto standard for running containerized applications.
Kubernetes (K8s) is an open-source system for ...

Great article! If you want to try out some of these kubectl commands, I run KubeSail which gives you a small free slice of our powerful, security-hardened Kubernetes cluster. You get full access to the Kube API, so you should be able to follow along and try applying all of the YAML in this tutorial.
Love the article, how you summarized the main K8s components and explained them in your own language. Especially the Services and Networking part that can be fuzzy ;)
Good job!
We need more like this one.
I hope the next one is on PV ;)
Thanks
It is not necessary to use alpine to minimize resources. There are easy ways to build image "from scratch". Like mount your empty image and put your staff in, for example
dnf install --installroot...just remember you'll need ca-certs if you're doing any tls in your container
oh.. that sounds interesting. I will take it a spin. Thanks 👍🙂
I can recommend you some useful tools
Thank you for the detailed article Sendil. I was thinking of doing this exact thing but you beat me to the punch. :D. Very well done. Keep up the good work.
Oops, sorry about that :). Between thanks.
Can't help recalling that each time I see anything on Kubernetes...
Thanks a lot for this great article.
Jus a little correction i think: "Alphine" should be "Alpine"
Thanks I updated 👍
Great and simple overview ... if you cover k8s rbac at some point - check this open source tool
github.com/alcideio/rbac-tool
Thanks :) will take a look :)
Thank you for that article!
Thanks :)
Great easy read, thanks Sendil!
Sorry, this is really not "for everyone". You just bombard the reader with an enormous amount of new concepts that are nowhere introduced nor defined. I don't doubt that this helps people who already know all these terms to systematize their knowledge, but calling it "for everyone" is really wrong.
This is a good one. Ideally I expect how Kubernetes works part to be for everyone except for few jargons like
pods. And have an explanation for them.May be I should have named it
Kubernetes for anyone who knows Docker?How about instead of calling something wrong, can you share the list of things that you feel needs an explanation. (feel free to comment) let us make this post for everyone :)
Well, you could start with explaining Kubernetes relies on Docker containers and how it's all related. I dug a little bit around Docker and Kubernetes seemed to appear here and there but I didn't have time to look it closer. So now I thought good maybe here I will know what's it all about. But here not a word about Kubernetes and Docker connection...
Yes, that's probably it. I really don't know anything about Docker. But that's also a part of the problem: you mention Docker only after 85% of your article, and of course I didn't get to there.
I tried. But there's too much of it, and the article is really long. As I said above, the fact that you didn't even mention Docker for 5/6ths of your article is illustrative. Probably it would need a thorough rewrite, and it still wouldn't be worth it.
Hmm, I'm working with Docker and compose for a year or two but I have to admit i still don’t really understand the differences between pods, services, deployments and load balancing strategies.
For every section i thought, “oh this is interesting” and then the section was over and i did not really get it.
I think it’s hard to cover such a complex technology in an article but maybe you could have made up one example application that you’ve built with Kubernetes and explain the details along it.
