AWS EKS configuration question

[john-b-yang]

Hi SkyRL team! I'm working through the tutorial for deploying OpenHands on Kubernetes here.

I was able to create an EKS cluster successfully:

eksctl create cluster --name openhands-cluster --region us-west-1 --version 1.32 --vpc-private-subnets subnet-1,subnet-2 --without-nodegroup

I'm trying to do the step of creating the nodegroup

eksctl create nodegroup --config-file nodegroup.yaml

nodegroup.yaml Configuration

Configuration:

apiVersion: eksctl.io/v1alpha5
kind: ClusterConfig
metadata:
  name: openhands-cluster
  # change as needed
  region: us-west-1

nodeGroups:
  - name: nvme-storage-2
    instanceType: i4i.4xlarge
    desiredCapacity: 8
    privateNetworking: false
    volumeSize: 50
    labels:
      node-group: nvme-storage
    securityGroups:
      # Change this to your security group ID
      attachIDs: [sg-...]
    preBootstrapCommands:
      - apt install -y xfsprogs
      # Mount the NVME volume
      - if ! grep -qs '/mnt/nvme' /proc/mounts; then mkfs.xfs -f /dev/nvme1n1; mkdir -p /mnt/nvme; mount /dev/nvme1n1 /mnt/nvme; echo "/dev/nvme1n1 /mnt/nvme xfs defaults 0 0" >> /etc/fstab; fi

I'm running into this error:

Error: all public subnets from vpc-..., that the cluster was originally created on, have been deleted; to create public nodegroups within vpc-... please manually set valid public subnets via nodeGroup.SubnetIDs

The error message is fairly explanatory, but I'm not sure how to go about making the subnets public? I am an AWS newbie, so this is my first time using a lot of these AWS features.

Also, at what point am I supposed to follow these instructions to run the OpenHands remote runtime? Is it after I've finished up the steps in the k8s deployment tutorial?
