Open Policy Administration Layer

What is OPAL?

OPAL is an administration layer for Open Policy Agent (OPA), detecting changes to both policy and policy data in realtime and pushing live updates to your agents. OPAL brings open-policy up to the speed needed by live applications.

As your application state changes (whether it's via your APIs, DBs, git, S3 or 3rd-party SaaS services), OPAL will make sure your services are always in sync with the authorization data and policy they need (and only those they need).

Check out our main site at OPAL.ac and this video briefly explaining OPAL and how it works with OPA.

Why use OPAL?

OPAL is the easiest way to keep your solution's authorization layer up-to-date in realtime. It aggregates policy and data from across the field and integrates them seamlessly into the authorization layer, and is microservices and cloud-native.

OPA + OPAL = 💜

While OPA (Open Policy Agent) decouples policy from code in a highly-performant and elegant way, the challenge of keeping policy agents up-to-date remains. This is especially true in applications, where each user interaction or API call may affect access-control decisions. OPAL runs in the background, supercharging policy-agents, keeping them in sync with events in realtime.

• 💡   Intro to OPAL

• 🚀   Getting Started:

  OPAL is available both as python packages with a built-in CLI as well as pre-built docker images ready-to-go.

  • Play with a live playground environment in docker-compose
  • Try the getting started guide for containers
  • Check out the Helm Chart for Kubernetes
  
  

• 💪   TL;DR - This one command will download and run a working configuration of OPAL server and OPAL client on your machine:

curl -L https://raw.githubusercontent.com/permitio/opal/master/docker/docker-compose-example.yml \
> docker-compose.yml && docker-compose up

  • How to extend OPAL to fetch data from your sources with FetchProviders

  • How to configure OPAL (basic concepts)

• 🎨   Key concepts and design

• 🏗️   Architecture

  OPAL uses a client-server stateless architecture. OPAL-Servers publish policy and data updates over a lightweight (websocket) PubSub Channel, which OPAL-clients subscribe to via topics. Upon updates each client fetches data directly (from source) to load it in to its managed OPA instance.
