However, I\'m not able to perform DN

Answer 1

So I been struggling for a couple of hours i think, lost track of time, with this issue as well.

Since i am using the default VPC but with the worker nodes inside the private subnet, it wasn't working.

I went through the amazon-vpc-cni-k8s and found the solution.

We have to sff the environment variable of the aws-node daemonset AWS_VPC_K8S_CNI_EXTERNALSNAT=true.

You can either get the new yaml and apply or just fix it through the dashboard. However for it to work you have to restart the worker node instance so the ip route tables are refreshed.
