Background:

I have an EKS cluster with 2 nodes (t3.small). The cluster is having several pods including:

• 1 pod for web frontend
• 1 pod for backend
• AWS ALB controller
• External DNS

Current behavior:

• All backend and web frontend pods + other AWS ALB pods (cert-manager, cert-manager-cainjector, cert-manager-webhook, app-backend-deployment, app-frontend-deployment, external-dns, aws-load-balancer-controller, etc. - 11 pods in total) are all allocated into 1 single node.
• The other node is only running 2 pods (aws-node & kube-proxy), meaning no application nodes are assigned to.
• Consequence: One node is frequently down or goes to non-ready status due to CPU/memory shortage, while the other is completely free and not being used.

Desired behavior (or my opinionated expected behavior): The pods should be allocated more equally.

Am I missing anything in the configuration?
