Kubernetes Ingress Controller: Beginners Tutorial with NGINX as an Example #devops #kubernetes

This video explains about Ingress & Ingress Controller in Kubernetes. It's a tutorial with NGINX as an Example for Ingress Controller. Explained about what is ingress, why we need Ingress Controller in kubernetes cluster in production, what are the different ingress controllers, setup of ingress and finally demo with NGINX as an Ingress Controller. The following are the concepts discussed

how to work ingress controlrt in kubeadm clustre

[nohandsignal]

thanks for the video
one small question
how does the ingress controller deployment know abt the ingress yaml?
if in case of service and deployment there will be labels and selectors like that what is the relation that it maintains between the ingress controller deployment and the ingress rules yaml
could you kindly please answer.

[jamestaylor]

hi there, can we use Ingress to redirect request based on port number to say RabbitMQ(5671) instead of paths in rules section. Just a small curious query.

[tonycavanagh]

I got lost when you used your command minikube service web --url.
I thought the object was for the service to use type: ClusterIP, not to use type: NodePort. when working with Kubernetes Ingress Controller. I have no idea what your web service yml file looks like.

Thanks very much! 1 thing that confuses me if you have time - does the "host" property need to actually be a purchased domain name, or can it be any name?
I'm guessing it can be any name, as we don't always purchase a DNS for our backend?

[santhoshakarotirajashekar]

Hi,
how we can pass the additional paths, for example, in my scenario,
/ is a react based front end application and
v2 is nodeJS based REST API project ..
when i pass additional paths v2/path/path/path ..etc application is only responding to v2/ not for other paths ..any clues here?

Hi Buddy, thanks for the video and explanation it was really good.

I'm new the kubernetes and i want to learn more from you.

I have query about this session.

1) host: hello-world.info you defined ingress.yaml file value contains hello-world.info is your hostname ? $ hostname

2) vi /etc/hosts

<ip of the machine> <host name>
192.168.64.2 hello-world.info

To adding name resolution you added minikube ip and hostname in to the host file.

In my case if i am using k8 setup with 1- master and 2-worker nodes setup (kubeadm installation ) then i deployed sample application as like you my pod will deployed in both worker nodes.

in this case i have to define my worker nodes ip and hostname into my master vm under the vi /etc/hosts file

worker1-ip hostname
worker2-ip hostname

could you please confirm my understanding is correct or not?

Thanks for you help.

Love the video!
Unfortunately I can't seem to get success. I'm roadblocked because the Ingress gateway always returns an empty ADDRESS after I apply it. Also, when I run "kubectl get pods -n kube-system" it does not show NGIX Ingress Controller. I have run "minikube addons enable ingress: as well as "minikube addons enable ingress-dns" many times. Both return with success.

When I run "kubectl describe [name_of_ingress_gateway]" I get no errors, but again address is empty

Also, something that confuses me is that you first mapped your selected host name to your NodePort's external IP which provided your LB with a public IP, but after you switched service from NodePort to Cluster-IP, the external IP would have been deleted, yet the host name of the Ingress still worked

I would love to see your comments about the demo. If you have any question or if you think there is something is missing, please put it in comments. Surely I will get back to you ASAP...Cheers..!!
