Understanding StatefulSets in Kubernetes

Today's video is all about StatefulSets and how they help us to run workloads that require persistence. These can include databases, caches, message queues and anything that requires data to be stored. Stay tuned for my video on persistent volumes as it will also play a big role in managing and running stateful workloads on Kubernetes.

Dude, your series on k8s is - by far - the celarest, most concise and illuminating set of vids out there. I sincerely commend you, sir.

[MuhammadUsman-ouio]

Greatly explained . Currently working as DevOps intern and really was stuck with this statefulset and deployment. keep up good work

[armadillo]

I am on the virtuous path of watching every single video of this channel. An practice it. So far it is going great and I have learned a ton.

[nandani]

Thank you for your awesome videos, one of the best series of videos on K8s on youtube. TYSM.

[konstantindimitrov]

I think I said it in one of you first videos but again, you are the best DevOps educator on youtube. Clearly you've got experience that many others don't. Your vids aren't some robotic read-out of the official docs for views, so I can always find something new. Great style, great structure. You definitely deserve more recognition but it's getting there and certainly it will get there!

[vikibadoni]

Very helpful. Thanks for the videos with a good emphasis on the "Why" part.

Your vedios are really helpful and i love the the way you explain it with real time use cases. Would request you to cover helm charts from scratch to complex. Lets say how to create helm charts, how to convert our own applications to helm charts etc etc. I would love to have some series of vedios on this with the ongoing standard use cases which currently organisations are doing. Thanks! keep the great work going going. Happy learning!!

I will rate you 100% . The content was too notch and the explanation was just what I need now.
I wanted to deploy a postgres database on k8s, so I sort for resources on data persistent and I couldn't find any that is more explanatory.

Your sample that resides in github was top-notch.

[dalohse]

you, sir, are answering all the exact questions which no one other answers. thank you.

[minhthinhhuynhle]

Thanks to you, I learned a lot of "production / professional" ways to understand and implement those strategies. None of your videos get bored, I even watch some vid 5-6 times to strengthen my knowledge until I completely understand everything. Thank you for your supports.

[hellboy]

I don't know what I would do without your channel. You have an amazing skill to explain complicated topics in such a wonderful, easy-to-understand way. Keep going!!
A video with Tekton would be great, if I can propose something.

[Admiral.MacDonnell]

You are so precise, even laser beam refracts. I really like your presentation. Thank you!

[tiagomedeiros]

stateful explained in a very clear way. Thank you for the video.

[derpherp]

This is a very very good tutorial. Thank you and subscribed!

[olenaqwerty]

very good in-depth explanation. just what was looking for. thanks

[NiteshKumar-doen]

You are best keep sharing the concept and. Keep it simple as other devops video are not easy to understand on another channels

[Belal-Khan]

This is an awesome series, but I wanted to point out an issue with the command @22:28. The command adds an extra ":6379" at the end of the string which is recorded in the env var.

The output from:
kubectl -n example get pods -l app=redis-cluster -o '

in my case was:

"10.244.0.6:6379 10.244.0.8:6379 10.244.0.10:6379 10.244.0.12:6379 10.244.0.14:6379 10.244.0.16:6379 :6379"

This causes the next cluster create command to fail. Took me a little bit to understand why the command was failing if anyone else runs into the issue.

[MultiDorin]

Nice explanation! Keep up the good work!

[sandy]

I loved this stateful sets explanation

[gopinadhlekkala]

It’s very clear and concise.. really appreciate it..
