[docs] Bootstrapping EKS cluster requires additional CSI driver configuration

[Bartlomiej Gmerek]

Hi,

Starting from K8s 1.23, there are additional steps needed to bootstrap a Juju controller on an EKS cluster. Without creating an EBS CSI driver service account, bootstrapping controller will timeout waiting for the volumes. This information is missing from the official docs.

Required steps are:

eksctl utils associate-iam-oidc-provider --region=<REGION> --cluster=<EKS CLUSTER NAME> --approve

eksctl create iamserviceaccount --name ebs-csi-controller-sa --namespace kube-system --cluster <EKS CLUSTER NAME> --attach-policy-arn arn:aws:iam::aws:policy/service-role/AmazonEBSCSIDriverPolicy --approve --role-only --role-name AmazonEKS_EBS_CSI_DriverRole

eksctl create addon --name aws-ebs-csi-driver --cluster <EKS CLUSTER NAME> --service-account-role-arn <SERVICE ACCOUNT ARN> --force

Kindly please update the docs.

Thanks in advance.

BR,
Bartek
