How does this work? The EFS CSI driver has this script that does kubectl logs on the efs-driver container: https://github.com/kubernetes-sigs/aws-efs-csi-driver/blob/master/troubleshooting/log_collector.py

It copies them directly from where containerd/docker are writing them. kubectl isn't installed on the EKS AMI by default so that method doesn't work.
