Ensure that the --authorization-mode argument is not set to AlwaysAllow

严重级别 1自动化openshift

说明

Do not allow all requests. Enable explicit authorization. Reads every node's effective kubelet configuration with oc get --raw /api/v1/nodes/<node>/proxy/configz; requires a cluster-admin oc login.

nodes=$(oc get nodes -o jsonpath='{range .items[*]}{.metadata.name}{"\n"}{end}') || exit 1
[ -n "$nodes" ] || exit 1
ok=1
for n in $nodes; do
  c=$(oc get --raw "/api/v1/nodes/$n/proxy/configz") || exit 1
  if ! { ! printf '%s' "$c" | grep -Eq '"authorization":\{"mode":"AlwaysAllow"' && printf '%s' "$c" | grep -Eq '"authorization":\{"mode":"'; }; then echo "noncompliant: $n"; ok=0; fi
done
if [ "$ok" -eq 1 ]; then echo compliant; fi

预期输出: compliant
