runtime - an abstraction library on top of the Open Policy Agent (OPA)

Introduction

The "runtime" project is a library that sits on top of OPA.

The goal of the project is to allow you to quickly write code that builds, runs or tests OPA policies.

It uses the options pattern to facilitate construction of Runtime instances specific to your needs. You can start super simple, using it just to build some rego into a bundle, or you can get more complex, using it to start a runtime with plugins, built-ins and other features.

Install

go get -u github.com/aserto-dev/runtime

Usage

// Create a runtimer, err:=runtime.New(ctx, &logger, &runtime.Config{}, runtime.WithRegoVersion(ast.RegoV1)))
iferr!=nil {
returnerrors.Wrap(err, "failed to create runtime")
}
iferr:=r.Start(ctx); err!=nil {
returnerrors.Wrap(err, "failed to start runtime")
}
deferfunc() { r.Stop(ctx) }()
// Use the runtime to build a bundle from the current directoryreturnr.Build(runtime.BuildParams{
OutputFile: "my-bundle.tar.gz",
}, ".")

You can find a more complete example in the example directory.
