Chef InSpec vs kube-score

Chef InSpec tests and audits applications and infrastructure against a desired state described in InSpec code. Its runtime framework and rule language express compliance, security and policy requirements. Reusable profiles group controls and can include versioning, platform requirements and dependencies. Resources support testing AWS, Azure, AliCloud and GCP infrastructure, and users can create custom resources. Tests can run locally or against cloud services and infrastructure such as Linux in Docker containers. Results can be exported as JSON, HTML or plain text, or sent to Chef Automate. The kitchen-inspec verifier also runs profiles through Test Kitchen. Chef offers premium CIS- and STIG-based profiles for compliance scanning. The free tier is for non-production workloads and personal, non-commercial use; the 30-day trial is for product evaluation under non-production conditions. Commercial licensing covers production and non-production workloads, with entitlements based on purchase order. Chef InSpec 7 requires EULA acceptance, and license-key requirements depend on the distribution source. Telemetry is enabled for free and trial tiers, but not commercial users.

kube-score statically analyzes Kubernetes object definitions and recommends changes intended to improve application security and resilience. Its checks cover container limits, NetworkPolicy targeting, PodDisruptionBudget, Pod anti-affinity, container probes, security context, and stable APIs. Optional checks include matching resource requests and limits, container ports, and seccomp profile configuration. You can configure tests to be ignored or enabled globally or for individual objects. kube-score works with Helm, Kustomize, static YAML files, Docker, and resources retrieved from a Kubernetes cluster. Its browser demo accepts Kubernetes YAML or JSON and, according to the maker, processes it in the browser without sending data to a server. Local options include prebuilt binaries for Linux, macOS, and Windows, along with Docker, Homebrew, and Kubernetes Krew. Output formats include human-readable, JSON, CI, and SARIF. In CI/CD, critical errors return exit code 1; warnings can also be set as the exit threshold. The free, MIT-licensed project recommends analyzing all applications deployed to the same namespace together. Building from source requires Go 1.21 or later.
