Polaris is an open source policy engine for Kubernetes that validates and remediates resource configuration against 30+ built-in best-practice policies, with support for custom policies written in JSON Schema. It runs as a dashboard, an admission controller (mutating/validating webhook), or a CLI for testing YAML in CI/CD pipelines.
Use cases
- audit kubernetes cluster for configuration best practices
- enforce security policies on kubernetes workloads before deployment
- validate kubernetes yaml files in ci pipeline
- check that pods have resource requests and limits set
- detect containers running as root or with privileged access
- automatically fix kubernetes misconfigurations with a mutating webhook
- visualize kubernetes configuration issues in a dashboard
- write custom kubernetes policies as code
When to choose
- you want policy-as-code validation of kubernetes manifests in CI/CD
- you need an admission controller to reject or auto-remediate non-compliant workloads
- you want a visual dashboard of cluster configuration health
- you need built-in security, efficiency, and reliability checks without writing Rego
When to avoid
- you need general-purpose policy enforcement beyond configuration checks (consider OPA/Gatekeeper or Kyverno)
- you need vulnerability scanning or image scanning (Polaris checks configuration, not CVEs)
- you need cost allocation and multi-cluster aggregation (that is Fairwinds Insights, the commercial product)
