@eravindar12 how did you deployed the pod with kube-bench? have you compiled the binary by yourself ?

[eravindar12]

@chen-keinan - JFYI, I have followed the steps outlined in the official kube-bench documentation and then updated the image tag accordingly. Subsequently, I deployed job-eks-asff.yaml into the EKS cluster.

I've configured permissions within an IAM Role using IRSA (IAM Role for Service Accounts) by following below example

@eravindar12 the error message implies on binary compiled with wrong OS or ARCH

[eravindar12]

@chen-keinan Could you please provide guidance on resolving the error message indicating that the binary was compiled with the wrong OS or archticture? Thank you.

I am using EKS version 1.29

@eravindar12 can you confirm that you have compiled kube-bench binary by yourself ?
