I am a frequent viewer of your KZfaq channel and I wanted to take a moment to express my sincere appreciation for the valuable content you consistently provide. Your videos have been insightful and have helped me gain a deeper understanding of various topics. The way you present information is clear, engaging, and easy to follow, making the learning experience enjoyable. Your expertise and dedication to creating informative content truly shine through. I wanted to kindly request that you could consider creating a video on the ISTHIO SERVICE MESH & HELM CHARTS. I'm confident that your thorough research and ability to explain complex concepts in a user-friendly manner would make it an invaluable resource for your audience. Once again, thank you for your hard work and dedication to your KZfaq channel. I look forward to seeing more of your insightful videos in the future. Wishing you continued success and inspiration!

First thing first, Thank you so much for all your efforts to share the knowledge. I want to learn k8s on urgent basis. But as your suggestion I have completed docker series first and then i am in k8s series now. So now, have a few questions as below, 1. If the service will take care of pod forwarding.? then what if the pod have multiple containers and i need connect from service to pod-> container-2? 2. if Nodeport service is using worker node IP, then why do we need this type? Hoping to get the answer sooner. And a request that, i am enthusiast in AKS instead of GKE. So, if you please make a brief video on that too, that would be great charan anna.!!!!

Hi, thanks for your interest in watching the videos. 1. There will be only one main container rest all called as helpers. So the request always will be forwarded to main container. Because not all containers expose their ports. 2. For instant testing you want expose the service to the external world. In that case we can use nodeport.

Is there runtime relation between manifest file and running deployment? Suppose if we miss manifest file, does that deployment gets stopped suddenly? How can we use manifest file in github? Can we use terraform to push deployment and pods without manifest yaml file?

Hi sir .. how do we check the communication between Nodeport--SVC-pods or LBs .. for a troubleshooting point of view like in normal seniors we can use PING but here how do we check .. i mean not like kubectl describe svc (svc name) .. if you give some troubleshooting command it will help

May I know your name? Internal load balancer is not exposed on the internet where external load balancer will be exposed over the internet. For load balancers there will be no port numbers, it depends on the application you are hosting behind the load balancer.
