hi, is there a link to the CRD video? thx

[@cokebooger]

This is the most straight forward explanation of operators I've seen. Thank you!

[@TechWorldwithNana]

Happy to hear Sean. Please don't forget to subscribe and share. I appreciate the support. Thank you. 🙂

[@tomekjankowski]

I've watched a number of videos on your channel. Never came across anyone who can talk about complex problems in such a wonderfully easy to understand way. Thank you!

[@katlegomolepo6830]

Nana you have no idea how simple your videos makes complex explanations, sheer class. Best explanation of operators I've seen.

[@earthling_parth]

Just saying "operators replace the human operators who know how to manage these applications" just clicked everything in my mind. This was very helpful as usual . Thanks Nana

[@hyderabadperlmongers3654]

Very clear explanation about operators, cleared all the doubts i have , thanks a bunch

[@annachaika6616]

Wow, finally I know how to explain what I’m working with, thanks!

[@minimalniemand]

I just stumbled upon a use case the other day and was asking myself if an operator was the tool for the job. Your video answered that question perfectly! thank you very much, it was very well made, too.

[@TechWorldwithNana]

Awesome! Glad that this has helped you Randy. 😊

[@rallabandisrinivas]

Waiting for her Udemy course in September, explaining concepts with use cases in most of her episodes . Thanks for all your effort to give awareness to devops community

[@ruslan_yefimov]

This is awesome, thank you so much :) I wish we had such lecturers at uni, but talking about this stuff on youtube is even more effective!

[@renyirish]

You were born to teach 🤩 Thanks again.

[@AaronNel]

You have produced some of the best content on these complex and new topics thank you.

Best explanation found on internet. You are good at explaining things. Your KZbin videos are good for people who can not afford paid courses (i.e. in developing countries).

[@lpsouza]

Hello Nana! Thank you for this videos! I learn more and more about k8s with your videos!

[@TechWorldwithNana]

That's really great, happy my tutorials are helpful for you 💡🙂

[@parthachattopadhyay2181]

Hi Nana, can you please create a video on k8 certifications with recommendations for people coming from different backgrounds.

[@pallavkan]

Partha bro i have a recommendation!! Certification is not going to help you in cracking the interview, i have done CKA training from simplilearn and believe me there is an ocean to learn in kubernetes in which CKA is just going to give you some fundamental ideas. Istio, falco, sysdig there is lot to learn. Telling you this because i cracked an interview by learning from youtube and k8 official document site

[@parthachattopadhyay2181]

@@pallavkan really appreciate your feedback. I was just wondering while working on application in k8 infra, would it be a good idea to get a certificate anyway. And if it makes my journey a little more wider.

[@pallavkan]

Partha Chattopadhyay check the courses on Udemy , zeal vohra has explained terraform and k8 quite well, if you want to learn the concept. The CNCF certificate of CKA is the recognised one in the industry 300$ 😃

[@fabiano9714]

Hi, greate vídeo. I have a question: Who is responsible for the database sincronization between the database pods ? How does it happen ?

[@TechWorldwithNana]

Hi Fabiano. Some Databases, like Elastic Search has part of it already configured in the application out of the box, for mysql you would need to do more yourself. but It is usually configured as scripts/code in the statefulSet definitions. If you check for example a mysql or elastic search statefulSet example, you will see the code for it.

[@ayushpratap4726]

Hi Nana! Please release a video on Setting up MongoDB cluster with MongoDB Enterprise Operator for Kubernetes along with persistent storage using stateful set.
