This whole series covering docker and kubernetes is excellent, precise and easy to understand. Congratulations and thanks for your efforts. You have great teaching abilities. I specifically liked videos that cover practical aspects - for example, application deployment using k8s and docker-compose etc. Keep up your excellent work.

Hey..!!! You know what.....You deserve a big applause...!!! U covered almost everything abt Statefulset in this short video in detail..Can't resist watching your next video..Cheers...:)
Such an awesome explanation. I, being a devops engineer myself found this very useful. Thanks for a lot of hardwork that you're doing behind these videos to present to audience like me.
Jeez, as part of a dev team who’s currently struggling with devops issues cause our affiliate company that’s supposed to host our apps are completely useless and unresponsive of our requests, your vids really make my life better ! Thanks !
Thank you for all the videos Nana. Really your videos are much better than any other videos in you tube or even paid ones. Really everytime i wait for your videos when you are going to upload on K8s :) Thanks again for the videos
Hi Nana, I started to follow your videos from 2dys back, all them are crystal clear to understand. Am preparing for an interview now so need detailed video about pod security policy. Cheers !!
Nana, thanks a bunch for such an awesome tutorial/explanation. This has cleared many of my concepts. Before this, I was thinking to have a single Volume for all the Stateful app replicas. Really appreciated your work... :)
Maybe it is really important to mention that: 1. Know the database (if you are going to deploy database in K8s). Not all works the same way. For example, sharding as concept (found in Elastic) is very important. 2. Know your application requirements. Where is not possible to have stateless application, state-full self-contained application (deployed as StatefulSet) might make sense.
Thank you so much Raman! 🙏🙂 Hope it will gain more attention soon from youtube, so that it will be suggested to people who are interested in k8s. I would also be thankful for any support by liking and sharing to people, who want to learn about Docker & K8s :)
So easily explained and with great clarity. You are a GEM 💎and a great inspiration. The animations are something that makes you very different and special. Thanks a lot Mrs.Nana for taking the pain to put those efforts in. Highly appreciated.👏👏👏👌👌👌
Amazing explaination. Thank you so much for you. please make and upload videos on how to implement the statefulsets and how it configuration file looks like and how the master and slave methodology for databases was implemented in statefulsets. I have lot of questions in this area only.please make and upload videos on my above requests.
@TechWorld with Nana there is probably a issue in description on 13:38. The service has name "svc1" but the pods dns names have `${pod_name}.svc2` rather `.svc1`
You are amazing¡¡ you don't know how much I've learned thanks to you¡¡ You have the ideas super clear and the resources are the best. Thank you so much¡¡
Thank you so much Nana , you're videos are excellent ! All your series on Kubernetes are like this ! You succeed to explain main concepts in a easy way and it's not so easy to do ! 👏👏👏
Thanks for this great overview of StatefulSet.Must interesting was the claim that sateful applications are not perfect for containerised environments. This is a very important information if you start learning containerisation.
Here, I have learned a lot of things for Kubernetes. Thanks for doing these tutorials. Can you please make a video for MySQL Master and Slave Concept?.
Hello Mam, A very well-explained concept for stateful sets. The most important part comes at the end that, the containerization platform is not suitable for stateful apps. Kudos to your explanation power. Keep posting such videos. 👍
She is a kubernetes wizard who has passion in sharing content. Who is doing a backup of this girl? :) thanks Ana for spending time preparing a high quality material.
Thanks a lot for this video it really helped me to understand the purpose of the Statefulset and I can say that it is a really nice feature that k8s propose. As I started to learn about k8s, it's a good learning step done today after watching this video.
I strongly agree with that so many others have said. You have created an excellent series on Kubernetes. Thank you very much. Do have plans to add a video about DaemonSet?
Fantastic video, thank you! What happens in this scenario: a stateful application continually receives requests to update a database (e.g. MySQL) that is hosted on the k8s cluster as a StatefulSet. What happens in the time between Master pod failure and spinning up a new Master pod? Are the update database requests buffered until a new Master pod is available that can write the updates to the DB?
Very crisp Video, covering lots of information! - One question, If the Master statefulset Pod dies, then who would(i.e. which slave) get the write power to the DB (i.e. persistent volume), and to which DB it shall write?
Nice explanation! -- Do you create your presentations in a video editor or use presentation software and then record your screen as you step through the presentation?
First I record my speech and if there are demo parts also my screen. Afterwards I do the editing and visualization/animations to my recorded voice . Everything with Screenflow
Excellent explaination.I had a small doubt If i understand correctly, for stateless applications ,all replica's of pods will use single pv. how all pods deployed on different nodes will be able to access single pv(AWS-EBS) case of stateless applications? .ebs is not allowed to share to multiple nodes
the whole video answers your question mate. To put it in simple terms, your front end applications, backend apps, mirco services are perfect candidates for deployment and volumes in deployment on the other hand can be useful to find data like certificates, logs, custom configs, etc..you can however also choose volumes for storing data
Great video!! What if the last pod went down due to node failure than how will the new pod clonned and how this works in multi AZ in AKS? Also how db sharding would work in case of DB in K8S cluster
She failed to explain the gist of stateful sets by focusing too much on the example. The storage is NOT replicated on its own, but in the case of a distributed MySQL database the slaves communicate with the master to obtain a copy of the data. The storage replication is part of the "application" itself, not the StatefulSet logic. The role of StatefulSets, among other things, is to ensure that pods are created in a particular order (changeable by a policy), help us configure a headless service allowing us to communicate with individual pods by creating DNS entries, and ensuring that each pod can request its own STORAGE by providing a PVC template as part of the StatefulSet. So good call on your part, Kubernetes does NOT take care of storage replication.
Great channel!!! Great content. Thank you so much Nana. Been looking for the “How to create a StatefulSet” video but I haven’t seen it. Can anyone direct me.
Hey Nana! As i told u that your channel is gonna take off like rocket in a very few times. Like your kubernetes series. Can u describe one Real-Time project? It will be good if u make terraform integration with k8s.
Nana, clear cut explanation. I need a suggestion, I am planning to bring my microservice architecture into Kubernetes eco. Should I keep my database outside or I can keep it in as Sts?

How can we upgrade Statefulset pods without traffic disturbance, like how to handle switchover b/w PRIMARY and SECONDARY?
Can you refer me a trustable source where you have seen pods part of statefulset replicates their STORAGE to next pod in the same statefulset?
