Does AWS Load Balancer have a cert-manager within?
I thought at the beginning that such certificate would then expire, but I have seen cert-manager is within ALB code https://github.com/kubernetes-sigs/aws-load-balancer-controller/blob/main/config/certmanager/certificate.yaml so that makes me hesitate about it.

Creating Network Load Balancer (SG supported) with AWS Load Balancer Controller
Detailed behavior changes can be found in the release notes for version 2.6.0 of the AWS Load Balancer Controller. https://github.com/kubernetes-sigs/aws-load-balancer-controller/releases The key points include:
-
Network Load Balancer now supports security groups
If you are using Kubernetes, you can enable security groups on your NLB by using AWS Load Balancer controller version 2.6.0 or later. Enabling NLB security groups using the controller enhances the nodes' security, as inbound rules can be simplified by referencing the NLB security groups. It also provides scaling improvements, as the controller keeps a constant number of security group rules per cluster.

How to use ACM public certificate for Nginx ingress controller?
You can install the AWS Load Balancer Controller, and then create an "Ingress" when you install your Nginx Ingress controller, possible with some necessary annotations.

Ingress controller confusion
Yes. Google's ingress controller talks to the GCP API and spins up an HTTP LB for you. The AWS LB Controller handles provisioning ALB's for you. And ... I guess other clouds exist too but these are the ones I am familiar with.
-
Can I create HTTPS listeners on an ALB without SSL termination
NLB don't support weighted target groups and for some reason are extremely slow when adding instances o removing them from target groups, which makes deployments a bit meh (old instances and new instances can be receiving traffic at the same time for up to 2 mins)

Upgrading Hundreds of Kubernetes Clusters
The second one is a combination of tools: External DNS, cert-manager, and NGINX ingress. Using these as a stack, you can quickly deploy an application, making it available through a DNS with a TLS without much effort via simple annotations. When I first discovered External DNS, I was amazed at its quality.

Kubernetes External DNS provider for Hetzner
One of the reasons why I chose Hetzner was that it WAS supported by the ExternalDNS project. I didn't quite understand why the Hetzner provider was pulled, but I saw that an attempt of re-adding it was refused, on the ground that the upcoming webhook architecture would have allowed to better maintain providers.

Looking for ExternalDns alternative for non k8s environment
so I am looking at having an automated way for new routers registered in Traefik to also have the corresponding DNS entry added to my Pihole instance similar to external-dns but obviously, this is exclusive to ingress on k8s environments. my current setup is traefik in a container on unraid.

Is a Load Balancer necessary for a HA Cluster?
You technically don’t need to run a load balancer or have a virtual IP for your control plane. If you control your dns, you can add an A record pointing to all IPs for your control plane nodes. It won’t load balance your traffic, but combined with something like External DNS it gives you HA for the control plane.
-
How can I assign an EIP to a Kubernetes deployment?
I normally deploy external-dns, which automatically updates DNS with the ingress controller's external IP address.

Cluster nodes on different networks
3) Use the Kubernetes External-DNS. I've never used this, but this is assuming it can update DNS for each pods/app to point to the correct Node (it'd need to update my Homelab DNS running on Windows Server)

I am stuck on learning how to provision K8s in AWS. Security groups? ALB? ACM? R53?
So here’s the solution I have taken for our current stack. EKS and its dependencies are created through terraform using the eks module as well as provision a route53 subdomain and a wildcard cert. Once we have that created, I have installed this deployment into the cluster via the helm module: https://kubernetes-sigs.github.io/aws-load-balancer-controller/v2.4/. This allows me to use kuberentes resources (load balancers or ingress objects) and it will handle all the provisioning of load balancers and security groups for me, based on my application yaml and annotations. We also use https://github.com/kubernetes-sigs/external-dns to manage all of our specific host names for the applications through annotations. So to generally put, terraform manages out Kubernetes clusters, and Kubernetes manages the deployment of anything needed for the application including volumes, load balancers, hostnames though Kubernetes system deployments
