Kubernetes Ingress Simplified | Ingress Vs Service | Ingress Controller Vs Ingress Resource

In this video we go over Kubernetes Ingress, explain differences between Kubernetes Service and Kubernetes Ingress, go over Ingress Controller and Ingress Resource, and understand why ingress is important in real world projects. We also go over advantages of ALB Ingress Controller on EKS. Also included a sneak peek into my next course - Rocking Kubernetes on EKS!

Impeccable content. Absolutely recommended channel for mastering K8's. Thanks for the YouTube algorithm. Atleast now I found such a wonderful mentor.

Great presentation style and very useful video. Your course looks very good! Thanks.

Hope your colleagues are too much happy to work with you.
Literally thinking why we don't have a teammate like this

It finally makes sense ! Thanks!
About 12:05, with IP Mode, does the fact that the ALB is routing traffic directly to Pods means that we are not using the k8s service's IP, and therefore not using the load balancing feature of services ? What about the rolling update of pods deployments; do we still benefit from this Deplyment feature even though we're targeting pods directly ?

Also, if I use the "IP Mode", will my service still have to be of type "NodePort", or can it now be "ClusterIP" type ?

this is the best video on ingress. one question, between urls its routing but within same url how does it do load balancing across replicas..? does it get to know of different repica instances and route traffic based on lb policy if does it get to know all repicas of a serice through ingress controller?

[diegoandreeporrasrivas]

Please launch that K8s course! Waiting for it

[shishirroy]

Excellent content. expecting a course only on real-world kubernetes project.

[vipinmon]

Excellent explanation. Keep posting videos like this.

Great video on Ingress. Looking forward to taking your Udemy courses soon, thanks for sharing all the knowledge.

[renatobertolaccini]

Amazing video thank you. Just one doubt.
Looking at yaml files where I can see the link between ingress controller yaml file and ingress resources yaml file?
Ok I have an incoming traffic, it hits my service (nodeport) that points to ingress controller but in the ingress controller yaml file I did not realize where it binds to ingress resource yaml file where my routes are.

Awesome video Raj. I am newbie to k8s . I have a question multiple ingress resources will work with same ingress controller if ingress class is same as alb, ingress controller will create another alb for new ingress resources with class alb or not.
Also loved the new course content, will surely purchase your course once available.

[tanchwa]

so does the ingress controller just function like any of the other control plane resources (kube-api, etcd, etc.) and it is responsible for deploying the ingress resource/ object?

Does this controller run on every node or have just one instance?

[ShivaKumar-jete]

I think we cannot use more than one ALB Load Balancer controller in same cluster, that is not supported yet

AGENT of CHANGE ??? LOL trying hard to copy

[nohandsignal]

love your efforts but honestly sometimes i`m not able to understand your slang, your english is speed bro.
but for the flow and presentation that you made for the walk through is awesome.
mostly no people here on youtube explained the ingress resource has to be deployed, atleast i haven`t came across.

[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.

[minizone]

Wow, Never came across this type of presentation .So smooth like a story

[nikhilsrivastava]

Awesome explanation Raj! Thanks for the video

[chrisvalen]

I can bately understand what you are saying

[pseabrook]
