Thanks Abhishek & Piyush. This video helped me in understanding a complex topic in simple terms. Great work.

[@TechTutorialswithPiyush]

Glad to hear it was helpful! 😊

[@abiorh]

Thank you so much i really do appreaciate. you both made the explanation so easy for anyone to understand.

[@TechTutorialswithPiyush]

That's awesome, thanks for the kind words!

[@GrigTech]

Thanks to both of you Abhishek and Piyush.

[@TechTutorialswithPiyush]

You're welcome buddy!

[@Alex-rl1gl]

As a Kubernetes admin for about 2 years I always struggled to explain to the customers what actually the Ingress is used. This is a beautiful explanation which i can forward to them from now on. Thank you so much. One small comment if I may, if you ever do such tutorials, it would be useful if you minimize the speaker's windows so we could see the whole white board's content

[@TechTutorialswithPiyush]

Thank you for the feedback! Yes, definitely

[@abc-edm]

Thanks Abhishek's sharing, learn alot from your video

[@shahrukhshaikh9313]

@abhishek you are brilliant yar

[@linuxgenius4667]

Awesome explaination, couldnt be more prcise that this. i am buidling the similar setup on ESXI in local env, i had problem with the loadbalancer and couldnt get my head around even after watching this video, as aws loadbalancer was not configured, for testing i used below ports from ingress-ngix 32081 and 31442 to access the app from local network ingress-nginx-controller NodePort 10.99.200.128 80:32081/TCP,443:31442/TCP for permanent i am going to implement MetalLB for loadbalancing .. NOTE: i have not gone through any other video from the series, which i am going to do from tomorrow, so dont know if that is discussed already.

[@TechTutorialswithPiyush]

Yes, you can use metalb as a loadbalancer so that it can be exposed externally and configure your backend service to it

Happy to see two of my favorites in one frame

[@ShashankBV-y5w]

Hey abhishek great explaination perfect for everyone who needs to learn from zero knowledge but one request after all the setup you showed and it started working please show it in the flow diagram it would be great to understand at the end for all confusions thanks piyush as well

[@TechTutorialswithPiyush]

Feedback taken, I will try to add the diagram in Github repo , thank you for sharing

[@rameshborusu5857]

Thank you Abhishek and Piyush for explaining the Ingress part. I believe I'm having the same issue which you guys faced at 30:37 part of the video. I'm not able to Curl the service which is of type ClusterIP from the master node but I can curl using ClusterIP from the node where pod is running. I have Calico as CNI for the Kubernetes setup. I tried troubleshooting for some time but no luck. I have one master node and 2 worker nodes setup in Azure. Can I know what steps you have followed to resolve it ?

[@TechTutorialswithPiyush]

Hello Ramesh, I believe I added the details in the Github repo, can you check the task.md as well for this video, it should have the steps

[@senthilkumar5129]

thank you both of you

[@TechTutorialswithPiyush]

You're welcome

[@MihirModi-ix7zw]

Sir, amazing collaboration with Abhisheksir. Thank you so much for this detailed information. I have one question regarding Ingress. For a website with 50-100 pages, we can write Ingress rules for hosts or paths. But when it comes to large companies like Amazon, with thousands of pages, subpages, and millions of products, how do they manage Ingress hosts and paths manually? how they set ingress rules?

[@TechTutorialswithPiyush]

Thank you for the feedback Mihir :) To answer your question With an ingress, you can assign subdomains to different services, or you can serve all the services under different context roots with some url rewriting. There would not seperate service for each product(considering millions of products), there would be a service for product catalogue which would have the API exposed containing the product information.

[@samipdave]

Hi thanx abhishek and piyush for such informative video , please explain annotation its difficult part to understand why we are using it in yaml.

[@TechTutorialswithPiyush]

Thank you Samip for the feedback! We use annotations in Kubernetes to store metadata about the k8s object, it is differant than labels. The rewrite target used in the video specifies that we are defining a Target URI where the traffic must be redirected

You installed nginx ingress controller on kubeadm cluster, at 44:19 you show existing service LoadBalancer, my question is - was it automatically created with Helm chart ? If i want Do the same on AWS EKS will i need to create NLB manually or it is installed automatically with helm-release of Nginx Ingress Controller ? what will be the costs?

[@TechTutorialswithPiyush]

If you are using a managed Kubernetes service such as EKS, your loadbalancer should be automatically created. You can check the pricing estimates using the pricing calculator.

[@thebotx3092]

@techtutorialswithpiyush Hi first of all thank you for this amazing series. I've one doubt regarding the nginx ingress. So Abhishek has changed the ingress type from LoadBalancer to NodePort 46:25. So which IP is assigned to ingress? Is that public IP or Internal IP?

[@TechTutorialswithPiyush]

Thank you so much for the feedback :) yes, it's a public IP as we are resolving it to the Ingress hostname which is also an externally available host.

[@thebotx3092]

Okay ​@@TechTutorialswithPiyush, thanks

[@prashantbathula5448]

The ip that got updated in Ingress is it a fixed static Ip ? Or it’s dynamic one that changes , my main question is which Ip we need to provide to network team who handles the Lb as they will need back end set to configure

[@TechTutorialswithPiyush]

I believe it should be a static IP.

[@ansarisalman6575]

load balancer which was created by an ingress controller, it loads balance between nodes as well?

[@TechTutorialswithPiyush]

correct

[@sashi-z4b]

hi sir i am update cluster ip adress my domain but outsite not working and interanl working with domain

[@TechTutorialswithPiyush]

You might have to update the DNS records to point to the updated cluster IP.

[@mklinux777]

in Kind, how to use Ingress iam trying to unsderstand..

[@TechTutorialswithPiyush]

To use Ingress in Kind, we need to perform some extra steps as documented over here kind.sigs.k8s.io/docs/user/ingress/

[@ravikantthikane5105]

Hi,Im using kubeadm and assigned load balancer using metallb to the nginx then how to access application with that ip

[@TechTutorialswithPiyush]

You can setup ingress rules that accept incoming traffic on a certain path and redirect it to the backend service. Can you follow the video and share what steps have you performed so far?

[@karthiksundaram544]

HI SIR can u tell the difference between kubernetes nodeports vs load balancers vs ingres

[@TechTutorialswithPiyush]

Hello Karthik, Can you check the video about services, I have explained in depth

[@poojaselvaraj7959]

Bro, if kubeadm or minikube cluster we are creating .And we create an ingress controller on the reference of the ingress resource it has to create a load balancer right ? If we do not configure any cloud like AWS or azure these ingress controllers can't give external ip ah ? Also it won't create a load balancer unless we configure the cloud is my understanding correct here ?

[@TechTutorialswithPiyush]

Your understanding of absolutely correct sister 👏👍

[@madhuppandey3151]

Can we check the output of ingress on the browser?

[@TechTutorialswithPiyush]

If you have updated the local dns entry then yes

[@guntreddirajesh]

🤩

[@YogeshJagadale-pk3pb]

why we are using annotations inside ingresss reource file ?

[@TechTutorialswithPiyush]

Using annotation of rewrite rule we are forcing the redirect on the target url

[@shyambardhaval-]

can we use ingress only in k8s or anywhere ?

[@TechTutorialswithPiyush]

Ingress is a Kubernetes object so only in Kubernetes
