- 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 RUclips algorithm. Atleast now I found such a wonderful mentor.
Great presentation style and very useful video. Your course looks very good! Thanks.
Wow , Never came across this type of presentation .So smooth like a story
Awesome explanation Raj! Thanks for the video
Great video man! Love the presentation.
Glad you enjoyed it!
Good content and presentation.
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?
Excellent explanation. Keep posting videos like this.
Thank you, I will
Excellent content. expecting a course only on real-world kubernetes project.
My Kubernetes on EKS Course is out now in Udemy!! If interested, please check out discounted ($9.99) link - bit.ly/3Eku9RH
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.
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?
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.
If the ingress class is same (let's say the alb), it will NOt create new alb , it will add another path to the same actual load balancer. That's why ingress so useful. rather than creating (and paying) for multiple load balancer, it creates multiple path in same load balancer. Thanks for watching, and thanks for interest in my course. In the final stages now!
NICE Video!!!
Qingwei, you are legend and master, ty for the kind words! Hope all is well in this crazy times.
Nice explanation
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 ?
From what I've read regarding ALB in IP mode : when a pod is scaled out, the alb-ingress-controller updates the ALB target group to add the IPs of the new pods in the service. The service IP is never targeted; only the pods IPs are.
Regarding new versions of deployments, I think that the K8s deployment "engine" deploys the new version of the pod alongside the old one, performs the docker-level health checks, then the K8s probes, then the ALB health checks, and finally the target group is updated by the alb-ingress-controller to target the new pods. So the features of K8s deployments are still used, even thought you’re targeting the pods IPs rather than the service IP.
best tutor thanks a lot Raj
You are most welcome
Hope your colleagues are too much happy to work with you.
Literally thinking why we don't have a teammate like this
Awesome explanation
Glad you liked it
Great video on Ingress. Looking forward to taking your Udemy courses soon, thanks for sharing all the knowledge.
Awesome, thank you!
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.
u need to add annotation to ingress resource yaml file . controller finds an annotation and creates alb for it
thank you
Welcome!
Waiting for the course bro, please
thanks !
You're welcome!
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.
I think we cannot use more than one ALB Load Balancer controller in same cluster, that is not supported yet
Please launch that K8s course! Waiting for it
Thanks Diego, appreciate it! Working hard on doing the finishing touches.
Not just little bit confusing :D
does ingress work with Fargate ECS?
Hey Amir, ingress is a kubernetes concept and does not apply to ECS. ECS can work directly with load balancer
I can bately understand what you are saying
Waiting for new course
Thanks Denys for the support as always. You are the #1 student enrolled for the CloudFormation course and I thank you for that!
Nhi samajh aya ache se
AGENT of CHANGE ??? LOL trying hard to copy
Please speak in your real tongue
