aws-xray-daemon VS aws-ebs-csi-driver

The AWS X-Ray daemon is a core software application that listens for traffic on UDP port 2000. It gathers raw segment data and relays it to the AWS X-Ray API. The daemon needs to work in conjunction with the AWS X-Ray SDKs and must be running so that the data sent by the SDKs can reach the X-Ray service. The X-Ray daemon is an open-source project that you can follow on GitHub. See more details of the AWS X-Ray daemon here.

xRay - IAM Policy AWSXRayDaemonWriteAccess for AWS X-ray Daemon

The AWS EBS CSI Driver relies on IAM permissions to communicate with Amazon EBS for volume management on behalf of the user. The example policy can be used to define the required permissions. Additionally, AWS provides a managed policy at ARN arn:aws:iam::aws:policy/service-role/AmazonEBSCSIDriverPolicy

I looks like the driver's permissions to invoke the EBS APIs was revoked and/or changed. When you install the EBS CSI addon you can either inherit permissions from the worker node or you can choose an IRSA role (preferred). If you use IRSA, the service account that the EBS CSI driver uses should have an annotation that references the ARN of the IAM role you selected, e.g. eks.amazonaws.com/role-arn: arn:aws:iam::111122223333:role/my-role. You can see an example of the IAM policy the driver needs here, https://github.com/kubernetes-sigs/aws-ebs-csi-driver/blob/fb6d456558fb291b13f855454c1525c7acaf7046/docs/example-iam-policy.json.

I'm know it's possible to write terraform code that exhibits that issue, but that's not the case in my experience. I'm using helm to deploy aws's ebs csi driver in the above setup. As you mentioned, if the eks cluster was destroyed before the helm provider attempted to use its API to destroy the helm deployment, it would cause problems. And I don't run into that issue. It's not luck of timing, either - I also have a CI process that deploys all of this, tests, and deletes it all that has succeeded hundreds of times.

Any Kubernetes cluster requires persistent storage - whether organizations choose to begin with an on-premise Kubernetes cluster and migrate to the public cloud, or provision a Kubernetes cluster using a managed service in the cloud. Kubernetes supports multiple types of persistent storage – from object storage (such as Azure Blob storage or Google Cloud Storage), block storage (such as Amazon EBS, Azure Disk, or Google Persistent Disk), or file sharing storage (such as Amazon EFS, Azure Files or Google Cloud Filestore). The fact that each cloud provider has its implementation of persistent storage adds to the complexity of storage management, not to mention a scenario where an organization is provisioning Kubernetes clusters over several cloud providers. To succeed in managing Kubernetes clusters over a long period, knowing which storage type to use for each scenario, requires storage expertise.

aws-ebs-csi-driver

Hello, we are running an EKS cluster (1.20) with aws-ebs-csi-driver (1.4.0). After recreating our whole cluster we can observe that the EBS volumes from our PVCs still exist but the "mapping" to the PVCs is gone.

OP could probably just layer their own CSI driver on top of an existing one (a la aws-ebs-csi-driver), but there's still several problems:
