Implement Instance Autoscaling: Configure autoscaling for worker nodes by using Karpenter to adjust resources based on demand dynamically.

A point worth noting is that using the AWS Load Balancer Controller decouples your node management with your cluster management. Let’s say we wanted to use Karpenter for autoscaling instead of the defacto cluster-autoscaler. Karpenter will not use AWS AutoScalingGroups but will instead create standalone EC2 instances based on the Provisioners you define. This means our previous approach of attaching AutoScalingGroups with TargetGroups will not work as the EC2 instances Karpenter manages will not belong to the AutoScalingGroup and therefore not be automatically attached to the TargetGroup. The AWS Load Balancer Controller doesn’t care how the nodes are created; only that they belong to the cluster and match the label selectors defined. Probably we will look into Karpenter again in the near future for our project now that it supports pod anti-affinity, as this was previously a blocker for us.

Built in AWS, Karpenter is a high-performance, flexible, open-source Kubernetes cluster auto-scaler. One of its key features is the ability to launch EC2 instances based on specific workload requirements such as storage, compute, acceleration, and scheduling needs.

Karpenter is a high-performance Kubernetes cluster autoscaler that dynamically provisions worker nodes to meet the resource demands of unscheduled pods.

Dan: Argo CD is the first tool I install. For AWS, I will add Karpenter to manage costs. I will also use Longhorn for on-prem storage solutions, though I'd need ingress. Depending on the situation, I will install Argo CD first and then one of those other two.

If you’re not familiar with Karpenter — watch my quick intro. But in a nutshell, Karpenter is a better node autoscaler for Kubernetes (say goodbye to wasted compute resources). It is open-source and built by the AWS team. Qovery is an Internal Developer Platform I’m a co-founder) that we’ll use to spin up our EKS cluster with Karpenter.
