About:
Polaris is an open-source tool that audits Kubernetes clusters for security, reliability, and efficiency best practices. It runs a series of checks against your workloads to identify misconfigurations and provide actionable remediation advice. Its main value is enabling proactive cluster hardening and compliance.
Key Features:
  • Configuration validation against YAML manifests or live clusters
  • Customizable scoring and policy definitions
  • Dashboard for visualizing audit results
  • Integration into CI/CD pipelines
  • Extensible check library for security and reliability
Use Cases:
  • Pre-deployment security scanning of Kubernetes manifests
  • Continuous compliance monitoring for production clusters
  • Educating teams on Kubernetes best practices
Alternatives:
  • kube-score – Focuses on static YAML analysis with simpler scoring, less feature-rich dashboard
  • kube-bench – Specifically checks for CIS Kubernetes Benchmark compliance, less focused on general workload best practices
