^{Originally posted by **AndrewWSHenry** September 18, 2024} hi, I have not been able to build the kube-bench container using the instructions for "Running CIS benchmark in an EKS cluster" [https://github.com/aquasecurity/kube-bench/blob/main/docs/running.md#running-cis-benchmark-in-an-eks-cluster](url). I have run the docker build command on Ubuntu 24.04 and OpenSUSE LEAP 15.6 and run into the same problem of the KUBECTL_VERSION ARG not being set/available. causing the wget to error. The instructions don't mention a need to set those values and a brief look seems to suggest that the makefile run by the dockerfile should be setting those values. Just wondering if anyone is aware of a reason why the KUBECTL_VERSION arg has no value? This is the relevant output. > Dockerfile:14 > -------------------- > 12 | # Add kubectl to run policies checks > 13 | ARG KUBECTL_VERSION TARGETARCH > 14 | >>> RUN wget -O /usr/local/bin/kubectl "https://dl.k8s.io/release/v${KUBECTL_VERSION}/bin/linux/${TARGETARCH}/kubectl" > 15 | RUN wget -O kubectl.sha256 "https://dl.k8s.io/release/v${KUBECTL_VERSION}/bin/linux/${TARGETARCH}/kubectl.sha256" > 16 | # Verify kubectl sha256sum > -------------------- > ERROR: failed to solve: process "/bin/sh -c wget -O /usr/local/bin/kubectl \"https://dl.k8s.io/release/v${KUBECTL_VERSION}/bin/linux/${TARGETARCH}/kubectl\"" did not complete successfully: exit code: 8

@AndrewWSHenry Thanks for reporting. We should add a default value for the KUBECTL_VERSION arg in the Dockerfile. Feel free to send a pull request for this. Thanks!
