The Kubernetes Metrics Server (https://docs.aws.amazon.com/eks/latest/userguide/metrics-server.html) is not deployed by default in AWS EKS clusters. However, we will need it for our Cluster Autoscaler, Horizontal Pod Autoscaler, Kubernetes Dashboard, etc.
Deploy the Metrics Server
Deploying is as simple as executing the command below:
kubectl apply -f https://github.com/kubernetes-sigs/metrics-server/releases/latest/download/components.yaml
Verify the Deployment
kubectl get deployment metrics-server -n kube-system
