Question regarding building of own kubebench image

[jaanhio]

hi all, i am a new user of kubebench on my EKS cluster

i was reading through the guide and came across the part where we are instructed to build our own kubebench image before pushing to ECR and referencing that image instead. https://github.com/aquasecurity/kube-bench/blob/main/docs/running.md#running-in-an-eks-cluster

question i have is, why though? why cant we run kubebench using aquasec/kube-bench:latest?

I have a guess it is because of dockerhub pull rate limits, but it is possible now to build one public AWS ECR image instead
