OPAL Helm Chart for Kubernetes

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).

Installation Guide

OPAL Helm chart could be installed only with Helm 3. The chart is published to public Helm repository, hosted on GitHub itself. It's recommended to install OPAL into a dedicated namespace.

Add Helm repository

$ helm repo add opal
$ helm repo update

Install the latest version

$ helm install --create-namespace -n opal-ns myopal opal/opal

Search for all available versions

$ helm search repo opal --versions

Deploy OPAL to your Kubernetes cluster

Install specific version (with default configuration):

$ helm install --create-namespace -n opal-ns --version x.x.x myopal opal/opal

Install specific version (with custom configuration provided as YAML):

$ helm install -f myvalues.yaml --create-namespace -n opal-ns --version x.x.x myopal opal/opal

myvalues.yaml must conform to the json schema.

Verify installation

OPAL Client should populate embedded OPA instance with polices and data from configured Git repository. To validate it - one could create port-forwarding to OPAL client Pod. Port 8181 is the embedded OPA agent.

$ kubectl port-forward -n opal-ns service/myopal-client 8181:8181

Then, open http://localhost:8181/v1/data/ in your browser to check OPA data document state.
