Jenkins Service Issue

[abhithakur2]

We are currently experiencing an issue with Jenkins. The service stopped unexpectedly and is unable to attach to its designated volume. It is displaying the following error:-

“
Warning FailedAttachVolume 57m (x107 over 60m) attachdetach-controller AttachVolume.Attach failed for volume "jenkins" : rpc error: code = Internal desc = Could not attach volume "vol-054ce663f9040ea17" to node "i-08599073745076191": error listing AWS instances: WebIdentityErr: failed to retrieve credentials caused by: AccessDenied: Not authorized to perform sts:AssumeRoleWithWebIdentity status code: 403, request id: 61e49f49-ccbc-4faf-9dd5-de8d225dfd3a

@abhithakur2 The error you're encountering indicates a permission issue related to volume attachment. Please check the following to help resolve it:

Amazon EBS CSI Driver Add-on:-
Navigate to the EKS cluster > Add-ons section in the AWS Console and verify that the Amazon EBS CSI Driver is installed and in a healthy state.

Node IAM Role Permissions:-
Ensure that the IAM role attached to your EKS worker nodes (EC2 instances) has the AmazonEBSCSIDriverPolicy attached. This policy is required for the nodes to interact with EBS volumes.
