[@sivaramaprasadprudhivi3623]

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.!!!!

[@NextOpsVideos]

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.

[@sivaramaprasadprudhivi3623]

Superb Explanation!💌from Hyderabd. Can you suggest "How to run automation testing script using kubernetes? As I have inserted script in Docker containerization"

[@NextOpsVideos]

You need to run the pod and kick off or you can run it as cronjob to make it schedule based.

appreciate your efforts Charan, Quest: @32m 20s, there is a service of type ClusterIP listed in the output of '"kubectl get all" cmd. is this coming from a previous test run? If not, I would like to understand how it got created when you haven't even run the service creation manifest yet!

[@NextOpsVideos]

There will be a default clusterip service for kubernetes endpoint, it gets created automatically.

[@NextOpsVideos]

Hi Mohan, thanks for watching 🙏 You can use kubectl exec -it podname to connect to the pod. Please share the good word about the channel if you can 🙏🙏🙏

[@VijayKumar-fj8mt]

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?

[@NextOpsVideos]

No such relation, after your apply the manifest file it gets stored in the etcd database automatically. So you can even retrieve it when ever you need until the deployment is running. Thanks for watching! Please share the good word about the channel, if you like the videos.

I am running the same commands but i created the cluster in Azure instead of GCP, but the worker nodes doesnt have public IP address created. What i am missing here?

[@NextOpsVideos]

When you create the cluster in gcp, somewhere in the options you can choose whether to allocate a public ip or not. Please check once.

Sir, I have 2 doubts. 1. If we have cluster ip for inter cluster communication. Then wat is the use of core DNS ? 2. Real time lo kuda same ive operations ah ?

[@NextOpsVideos]

CoreDNS is internal communication and used for name resolution. Yes

[@Manju_Maddela]

What exactly internal lb amd external lb and also plz provide port numbers details

[@NextOpsVideos]

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.
