aws-load-balancer-controller VS ingress-nginx

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.

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:

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.

I use the AWS Load Balancer Controller: https://github.com/kubernetes-sigs/aws-load-balancer-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.

aws-load-balancer-controller

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.

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)

# Add NGINX ingress using Helm eks.HelmChart( self, "NginxIngress", cluster=cluster, chart="ingress-nginx", repository="https://kubernetes.github.io/ingress-nginx", namespace="ingress-nginx", values=helm_values )

ingress-nginx

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.

resource "helm_release" "icrelease" { name = "nginx-ingress" repository = "https://kubernetes.github.io/ingress-nginx" chart = "ingress-nginx" version = "4.9.1" namespace = kubernetes_namespace.icnamespace.metadata[0].name set { name = "controller.ingressClassResource.default" value = "true" } }

helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx helm repo update helm upgrade --install ingress-nginx ingress-nginx/ingress-nginx --namespace ingress-nginx --create-namespace -f custom/ghost/nginx.yaml

For example, if you chose Nginx Ingress, you will use some of its dozens of annotations that are not portable if you decide to switch to another Ingress implementation like Apache APISIX.

The controller is installed with helm upgrade --install ingress-nginx ingress-nginx --repo https://kubernetes.github.io/ingress-nginx --namespace ingress-nginx --create-namespace

Everything in the YAML snippets below — except for ingress configuration — relates to configuring the NGINX ingress controller. This includes customizing the default configuration.
