• See also: Configure privileges for EBS CSI using ebs csi irsa role module

0) Install driver

helm repo add aws-ebs-csi-driver https://kubernetes-sigs.github.io/aws-ebs-csi-driver
helm repo update
helm upgrade --install aws-ebs-csi-driver --namespace kube-system aws-ebs-csi-driver/aws-ebs-csi-driver

Release "aws-ebs-csi-driver" does not exist. Installing it now.
NAME: aws-ebs-csi-driver
LAST DEPLOYED: Mon Sep 26 08:02:42 2022
NAMESPACE: kube-system
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
To verify that aws-ebs-csi-driver has started, run:

    kubectl get pod -n kube-system -l "app.kubernetes.io/name=aws-ebs-csi-driver,app.kubernetes.io/instance=aws-ebs-csi-driver"

NOTE: The [ CSI Snapshotter ](https://github.com/kubernetes-csi/external-snapshotter) controller and CRDs will no longer be installed as part of this chart and moving forward will be a prerequisite of using the snap shotting functionality.

Output after installation:

kubectl get pod -n kube-system -l "app.kubernetes.io/name=aws-ebs-csi-driver,app.kubernetes.io/instance=aws-ebs-csi-driver"

1) Grant driver IAM permissions

Choose one of the following methods:

• 1.1 Using IAM instance profile - attach arn:aws:iam::aws:policy/service-role/AmazonEBSCSIDriverPolicy policy to the instance profile IAM role and turn on access to instance metadata for the instance(s) on which the driver Deployment will run.
• 1.2 EKS only: Using IAM roles for ServiceAccounts - create an IAM role, attach the policy to it, then follow the IRSA documentation to associate the IAM role with the driver Deployment service account, which if you are installing via Helm is determined by value controller.serviceAccount.name, ebs-csi-controller-sa by default
• 1.3 Using secret object - create an IAM user, attach the policy to it, then create a generic secret called aws-secret in the kube-system namespace with the user's credentials
  • Create IAM user: aws iam create-user --user-name ebs-csi-user
  • Attach policy: aws iam attach-user-policy --user-name ebs-csi-user --policy-arn arn:aws:iam::aws:policy/service-role/AmazonEBSCSIDriverPolicy
  • Create secret:
    • aws iam create-access-key --user-name ebs-csi-user
    • kubectl create secret generic aws-secret --namespace kube-system --from-literal "key_id=${AWS_ACCESS_KEY_ID}" --from-literal "access_key=${AWS_SECRET_ACCESS_KEY}"
