Kube-score
A tool that performs static code analysis of your Kubernetes object definitions.
Overview
Kube-score is a tool that performs static analysis of Kubernetes object definitions. It analyzes your YAML or JSON manifests and gives them a score based on a set of built-in checks. These checks are designed to identify issues that could impact the reliability, security, or performance of your applications, such as missing health probes, resource limits, or running as a non-root user.
✨ Key Features
- Static analysis for Kubernetes best practices
- Checks for reliability (e.g., probes, replicas)
- Checks for security (e.g., non-root user, read-only root filesystem)
- Provides a score and detailed recommendations for improvement
- Easy to integrate into CI/CD pipelines
🎯 Key Differentiators
- Focus on actionable recommendations for improving reliability and security.
- Simple, opinionated set of checks based on community best practices.
- Scoring system provides a quick measure of configuration quality.
Unique Value: An easy way to get immediate, actionable feedback on how to make your Kubernetes configurations more reliable and secure.
🎯 Use Cases (3)
✅ Best For
- Running `kube-score score my-files/*.yaml` to get a list of critical and optional recommendations for improving Kubernetes manifests.
💡 Check With Vendor
Verify these considerations match your specific requirements:
- Basic schema validation (Kubeval is better for this)
- Enforcing complex, custom organizational policies
🏆 Alternatives
While tools like Checkov are broad security scanners, Kube-score is specifically tailored to Kubernetes operational best practices, like setting probes and resource requests/limits.
