Overview

jsPolicy is a policy engine for Kubernetes that allows you to write policies in JavaScript or TypeScript. It is designed to be a more flexible and developer-friendly alternative to Rego-based policy engines. jsPolicy can be used to validate, mutate, and generate Kubernetes resources, as well as to react to events in the cluster.

✨ Key Features

  • Write policies in JavaScript or TypeScript
  • Validation, mutation, and generation of resources
  • Controller policies for reacting to cluster events
  • Access to the full Kubernetes API within policies
  • Leverages the V8 JavaScript engine for performance
  • Debugging and testing with standard JavaScript tools

🎯 Key Differentiators

  • Use of JavaScript/TypeScript for policies
  • Controller policies for event-driven automation
  • Developer-friendly tooling and ecosystem

Unique Value: Empowers developers to write powerful and flexible Kubernetes policies using the familiar JavaScript/TypeScript language and ecosystem.

🎯 Use Cases (3)

Implementing complex policy logic that is easier to express in a general-purpose language Teams with strong JavaScript/TypeScript expertise Creating policies that react to events within the cluster (e.g., sending a Slack notification when a specific resource is created)
