OPA Rego is ridiculously confusing - best way to learn it?

• Kubewarden

  4 131 9.5 Rust

  Kubewarden is a policy engine for Kubernetes. It helps with keeping your Kubernetes clusters secure and compliant. Kubewarden policies can be written using regular programming languages or Domain Specific Languages (DSL) sugh as Rego. Policies are compiled into WebAssembly modules that are then distributed using traditional container registries.

  

An alternative to OPA (and Rego) is Kubewarden (kubewarden.io), which can actually run Rego policies, but really allows policy writing in any language that compiles to wasm. This opens up your options a lot.

  jsPolicy - Easier & Faster Kubernetes Policies using JavaScript or TypeScript

  

I struggled with understanding OPA too! I have not seen this mentioned, but one straightforward alternative is JSPolicy (https://www.jspolicy.com/), which allows you to write policies in Javascript or Typescript. It is really easy to understand and get started.
