kube-bench, The CIS Node Checks Run To A Summary
kube-bench on EL 10 from the GitHub release; get_url refuses it unless its SHA-256 is in the vendor's checksums file, and the live test re-checks it, then installs the benchmark definitions and runs the cis-1.10 node checks with --exit-code 42: on a host with no kubelet they FAIL, the summary prints, the exit code is 42. Pinned. Original role, live-tested on Rocky Linux 10.
Verification
Live-testedReally deployed to a container sandbox, proven idempotent (a second run changes nothing), verified against the role’s assertions, then torn down.

Documentation
kube-bench
Aqua Security kube-bench on EL 10 from the vendor's release, checked against the
published SHA-256, pinned to a version, installed as root's binary
in /usr/local/bin. Original role for EL 10, live-tested with podman on
Rocky Linux 10.
No package worth the name. EL 10 carries no kube-bench, and a
third-party repository is one more key to trust. This role takes the
release from github.com/aquasecurity/kube-bench, has Ansible's get_url refuse the asset unless
its SHA-256 is the published one, and the live test checks the asset on
disk against the same published value again.
Pinned. kube_bench_version is what gets installed, kept in a directory
of its own so the checksum file and the asset it names stay together. A
newer release is a variable change and a run; the same version is
changed=0.
Proven to run. The live test runs kube-bench run --targets node --benchmark cis-1.10 --config-dir /etc/kube-bench/cfg --config /etc/kube-bench/cfg/config.yaml --exit-code 42 and expects
"== Summary node ==" - the binary ran all the way to the point where it
needed something this host does not have.
The CIS node checks, run on a host that is not a node. The live
test runs kube-bench run --targets node --benchmark cis-1.10 with the
benchmark definitions this role installs under /etc/kube-bench/cfg and
--exit-code 42: on a host with no kubelet the checks FAIL, so the exit
code is 42 and the summary is printed - the checker ran through the whole
section. The JSON form names the benchmark; an unknown benchmark is
refused. On a real node the same command reads the kubelet's flags and
files and scores them.

ansible-argocd-cli
The argocd client on EL 10 from the GitHub release, refused by Ansible's get_url unless its SHA-256 is the one in the vendor's cli_checksums.txt, and re-checked with sha256sum -c by the live test, which then runs argocd app list with no server and expects 'server address unspecified'. The server is a cluster install, not this role. Original role, live-tested on Rocky Linux 10.
ansible-argo
argo on EL 10 from the GitHub release; the asset is a bare gzip; get_url refuses it unless its SHA-256 is in the vendor's checksums file, and the live test re-checks it, then has lint --offline pass a valid Workflow and fail one whose entrypoint is missing (exit 1); list stops at the missing cluster. Pinned. Original role, live-tested on Rocky Linux 10.
ansible-cilium-cli
cilium on EL 10 from the GitHub release, refused by Ansible's get_url unless its SHA-256 is the one in the per-asset .sha256sum Cilium publishes, and re-checked with sha256sum -c by the live test, which then runs cilium config view with no cluster and expects the refused connection. Installing Cilium into a cluster stays yours. Original role, live-tested on Rocky Linux 10.
ansible-flux-cli
flux on EL 10 from the GitHub release, refused by Ansible's get_url unless its SHA-256 is the one in the vendor's checksums file, and re-checked with sha256sum -c by the live test, which then runs flux check --pre with no cluster and expects the refused connection. Flux also signs the checksums with cosign; this role checks the hash. Original role, live-tested on Rocky Linux 10.
ansible-helm
helm on EL 10 from get.helm.sh, refused by Ansible's get_url unless its SHA-256 is the one in the .sha256sum file published beside the tarball, and re-checked with sha256sum -c by the live test, which then runs helm list with no cluster and expects 'kubernetes cluster unreachable'. Pinned; a newer release is a variable change. Original role, live-tested on Rocky Linux 10.
ansible-helmfile
helmfile on EL 10 from the GitHub release, refused by Ansible's get_url unless its SHA-256 is the one in the project's checksums file, and re-checked with sha256sum -c by the live test, which then runs helmfile list on a one-release file with no helm on the host and expects it to read the file and stop at the missing helm; pair it with the helm role. Original role, live-tested on Rocky Linux 10.
