Looking forward on Kubernetes 1.27: Avoid Collisions Assigning Ports to NodePort Services

[@AntonPutra]

What's your use case for NodePorts?

[@zekeluther]

@@AntonPutra chatbot platform with different market region.

[@AntonPutra]

@@zekeluther I mean your use case for nodeports, why not to use load balancer or ingress?

[@675FresH]

Thanks for content Anton!
May I ask your opinion, is it worth getting a certificate in Kubernetes(CKA or CKAD)?

[@AntonPutra]

Personally, I never pay attention to whether a candidate has certificates or not. Perhaps someone else does.

[@nforlife]

That's is a perfect answer

[@maxmustermann9858]

Great Explanation! But I’m still not sure what to use for my setup, I want to setup a kubernetes cluster in the cloud so each node one VM. My cloud provider has a Load Balancer service but limits the possible targets it can connect to, so I thought I will connect the Cloud Load Balancer to a Ingress/Load Balancer on the Cluster which then routes the traffic accordingly. That way I only use 3 Targets of my load balancer and my Cluster also controls the certs, so I don’t need to pay extra for more certs and load balancer recourses.
How could I accomplish that, and is this even possible when wanting a production grade/ready cluster?

[@AntonPutra]

You can use the Nginx ingress controller. Set it up using a single 'target,' possibly two for HTTP/S, and then internally route to your services using the Nginx controller.

[@maxmustermann9858]

@@AntonPutra Thanks! So my way wasn’t completely wrong. But as I understand this would now be a single point of failure, so how can I have HA Ingress Controller? Then the external load balancer can point to the 3 or more ingress controller.

[@xianxiangchang5251]

What about using NodePort to aggregate different services under 1 load balancer using backends, instance-groups, url-maps, and HTTPS proxy?

[@AntonPutra]

Well that's how cloud providers used to do it behind the load balancer type service. Nowadays, they utilize IP mode and route traffic directly to the pod. On-premise, perhaps...

[@kaushikkm9336]

When we use the ingress, what should be the backend service type ? is it OK if its ClusterIP ?

[@AntonPutra]

Use ingress when you want to share one load balancer among multiple services, which is limited to HTTP/S only. Yes, most of the time you would use ClusterIP, except in some edge cases when you use the AWS Load Balancer Controller in instance mode.

[@ashadujjaman_hiru]

Would you please share a tutorial for onpremise scenario, How can I deploy Ingress my onpremise kubernetes cluster?
Please please please 😊

[@AntonPutra]

For on premise use metallb to create load balancers, then use it to deploy ingress.

what lesson number is this? can't fin the docs in github

[@AntonPutra]

I think I didn't commit any code for this lesson

[@thedeadbaby]

Why does everyone show the same diagram with a load balancer with many arrows coming out of it, one of which is going into a kubernetes cluster? This only serves to confuse people, as if the data from the load balancer is a straight line pipe into a single cluster. This is not how it actually works. The external load balancer talks directly to the nodes themselves. If you're trying to set up a service mesh, maybe this diagram is accurate, but you're simply confusing people if this is not the case.

[@Circe-wz3kg]

What do you mean? The arrows on one end are either the ingresses or services themselves and on the other end it's control plane

[@RobertGaz]

почему так сложно обяснить получше про LoadBalancer service? Ты говоришь, что он открывает под во вне, но совершенно непонятно, нужно навешивается реально какой-то балансировщик нагрузки или нет? например на 5:00 по смыслу да. а в остальном видео по смыслу нет.

[@AntonPutra]

I didn't understand the question. In the cloud, the LoadBalancer service creates a cloud load balancer and routes traffic to your app; on-premise, it depends on your configuration. Also, LoadBalancer can use node ports underneath, and if Kubernetes supports native networks (without virtual network plugins such as Flannel, Calico), it can route directly to your pod's IP address. (I don't have a Russian keyboard.)

[@RobertGaz]

@@AntonPutra Hey Anton. Thank you so much for answering! Now this seems to be clear for me.
