increase eks max pods

How Do I Enable the Prefix Mode?
You should create the node group with max-pods-per-node

Example:

eksctl create nodegroup --cluster adil-eks-cluster --region eu-west-1 --name adil-nodes --max-pods-per-node 110

If you create your node group with YAML:

managedNodeGroups:
  - name: adil-nodes
    instanceType: t3.medium
    desiredCapacity: 2
    minSize: 2
    maxSize: 4
    maxPodsPerNode: 110

After your nodes are created with a new limit (110), you can enable prefix mode:

kubectl set env daemonset aws-node -n kube-system ENABLE_PREFIX_DELEGATION=true
