Sir how can i access for domain i have add domain i am accessing within cluster but i can't access in external world in my domain what i should add in dns for access my application in my domain
Thanks for the video, But how can can we route if the service is on the other namespace and ingress resource is on other. I try this service: name: restapi.other-ns port: number: 8080 it gives me error
Hi Ayush, I am glad the videos were helpful. Please dont hesitate to reach out to me if you want to discuss things in general. The link is on my website.
Hi Vivek, It is a good content. Great work ! I am trying to do the curl to the internal IP/path of the ingress , but not getting any response from application. Application is configured already. Could you tell the reason?
Can you please explain it a bit more, if you are accessing one application from another application that is in the same cluster, you won't need ingresses. You can easily use clusterIP kind of service. Or is it something else that you are trying to do.
Hi, If we are trying to connect to the application from another application that is inside the same kubernetes cluster we, most of the times, use cluster ip type of service to communicate. I would like to emphasize, not the ip but service name. Ingresses have separate use cases that I have covered in another video.
Your explaination makes me fuzzy because you don't organize the article before publishing it. You can try note down the words and reading from it. Or either trim the videos and add correction to video. For example: 25:20 > Where is the "Application is not Listening to @#(*@&#!&#!" ? We don't like Implicit Understanding.
Hi 👋, I am sorry to hear that but I don't trim the videos down because I want people to see me fail and then recover from that failure. I think this is also helpful in learning how to debug things.

Thank you for the feedback though, please don't hesitate to post if you have some more.

Hi Vivek Thanks for the great content. I have a query i don't want to expose my application to the public through ingress but still I need ingress to expose the service to the private network how to do it?
Hey, To refer a service from ingress the service needs to be in the same namespace. If your service is in different namespace, you will have to create ingress in that namespace.
Hi Vivek , i have one strange requirement , My One of the api path will start from static/ and task/ but in path type i need to mention only one path selection because i have same contaxt in anothe apply too so how can i done this
I am on minikube environment and I have deployed ingress controller and deployed nginx app but the ingress controller's service which is of type LoadBalancer is not given any external IP address and stays in mode. So when I create Ingress component I can not access that nginx app through web browser. Can you help please please?
Hi Arash, Ingresses are going to work only on the environments where a load balancer can be created dynamically. So, its not going to work on minikube. You should try any cloud provider and things would work.
That's a good question, I can't think of a lot of scenarios right now. But one is, let's says you don't have to use path based routing and want to rely on cloud providers load balancers to do the forwarding.
I found this video very informative. Great work!!!! It will be great if you can make video on how we can assign one static-ip to a namespace, and for all outgoing traffic from a pod of a given namespace. Thanks
Hey Sourabh, I am not sure if we can assign one static IP to the namespace. Would you mind sharing the use case that you have or a link where you read about this.
Hi Vivek we are trying to expose the nginx via the ingress, but when trying the functional test with the DNS or ip address the connection is not establishing, getting connection failed. Note:- recently we had changed the dns name.
Hi, You can try to check the logs of the ingress controller to see what's happening there. Also I am assuming you are accessing the application using external IP of the load balancer service.
@@viveksinghggits your are correct but when I’m trying external IP address it’s working getting 200 success code, but I’m using the actual dns ip it getting 404 error
404 simply means that you are not specifying correct resource path, I don't think the problem is related to k8s. Can you verify which resource path your application is running at, and try that in the URL.
Hi Vivek, I am facing an issue. When i am specifying the path as /apis i am getting "Cannot GET /apis/get" , ingress is not able to reach my service but when i change the path as / in the ingress resource its working fine.
Hi Aditya, I am suspecting there is something wrong with either the endpoint that you exposed your application on, or the path that you are specifying in the ingress resource. I would recommend re-checkijg those. Let me know if you find them to be correct.
Hi Vivek! I had a doubt regarding the resource config. In my org, we are using Couchbase db and on the login page of couchbase itself, it uses more than 5-6 different paths after the IP (/couchbase, /ui, /pools, /abc etc.). I cannot separate it via hosts and currently I have to go through each page and get all the paths and define it in ingress separately. I cannot also define path as "/" for couchbase since other applications get affected by it. Is there any possible solution or easier method for it?
Hi Vijay Thank you for the great content. Im exploring on deploying a Ingress controller on kubernetes cluster which is on VMware. Since there is no load balancer, how do i install it? Could you please give me some insight.

@@viveksinghggits suppose if i have a cluster which i can access through nodeport eg : ip : 30234. I don't want to access with some name eg ip: /chaitanya What are the possible ways to do.?
You can access that using node IP and port combination for any of the nodes. But the problem is which particular node IP you are going to share with clients. Not an ideal way to expose your application.
Hi KK, I have just uploaded a video that explains how we can run images that are available on private container registry. Here is the link th-cam.com/video/XE76fyM9XyE/w-d-xo.html
Hi Vivek, Can you please help in understanding how, the address of the ingress is decided? I am running a minikube, server, the ingress address is always set to 127.0.0.1. Under what cases , it would be different ? Thank you.
Hi Prateek, We will have to see what are some of the solutions out there, to get ingress working on these environments where we can't have an external IP created. I think there are some solutions like metallb, but I have not explored that. But if we talk about the clusters that are setup on cloud environments, when we install an ingress controller, a load balancer is created on the cloud environment and IP of the load balancer is how the external IP is generated.
hello Vivek Sir, i have watched this video ....explanation is simple it is very helpful. I need one help. after doing practice , i read k8s docs about ingress ... below side i show Ingress Class ... I want to try this ingressclass also. when i type kubectl get ingressclass , error message is :- the server doesn't have a resource type "ingressclass" . How can i add ingressclass resource to my bare metal K8s cluster.
Hello Vivek,Can you please make a video on core dns and node local dns please. Thank you so much for explaining everything that is needed. Thank you so much.
Hi Vivek Thank you for the video. When i deploy ingress from helm chart - so the default type is loadbalancer, But external ip is not getting assigned in kubernetes cluster for that ingress service - What could be the reason for it?
Hi 👋, Where are you deploying the ingress controller, it looks like load balancer is not being created and that is the reason external IP is not being assigned.
Thanks Vivek for the reply ,So i m using onpremise kube cluster and using an external lb in onpremise, in that case it is not assigning to the ingress service.
Thank you for the good stuff - I did not know that we can run ingress resources without specifying ingressClass or annotation - Also could you make a video about installing ingress controller on bare metal with out using Helm charts.
Hey, thats a good point Fayaz, in case of bare metal we will have to somehow setup the load balancer manually because in that case we won't have a cloud controller manager running. One of the responsibilities of cloud controller manager is to look for LoadBalancer service and create Cloud Load Balancer. If we talk about the way we installed we didn't actually use helm, we just applied some manifests file in the cluster. Let me know if this helps, or there is something else that we should discuss about.
This helped tremendously! Thank you!
