KubeLinter vs PSRule for Azure

KubeLinter is a free, open-source static analyzer for Kubernetes YAML files, Helm charts, and Kustomize manifests. It checks production-readiness and security practices, including non-root containers, least privilege, and keeping sensitive information in secrets. Users can enable or disable checks and create custom checks for organizational policies. Failed checks produce remediation recommendations and a non-zero exit code. KubeLinter can generate several output formats in one run, including SARIF and JSON, and supports pull request scanning. Documented installation methods include Go, release binaries, Homebrew or LinuxBrew, nix-shell, and Docker. Container images are signed with cosign, with a public verification key supplied. The project uses the Apache License 2.0 and lists no paid tiers. Its README identifies StackRox as creator and Red Hat as current maintainer. The README also warns that commands, flags, and configuration formats may change. The latest listed release is v0.8.3.
