Overview

authservice helps delegate the OIDC Authorization Code Grant Flow to the Istio mesh. authservice is compatible with any standard OIDC Provider as well as other Istio End-user Auth features, including Authentication Policy and RBAC. Together, they allow developers to protect their APIs and web apps without any application code required.

The image is available on cgr.dev:

Usage

There are different ways to use the authservice image. You can try to run the image with the following docker-compose file:

version: "3.9"

services:
  envoy:
    image: cgr.dev/chainguard/envoy:latest
    command: -c /etc/envoy/envoy-config.yaml --log-level warning
    ports:
      - "8080:80"
    volumes:
      - type: bind
        source: envoy-config.yaml
        target: /etc/envoy/envoy-config.yaml

  ext-authz:
    image: cgr.dev/chainguard-private/authservice:latest
    volumes:
      - type: bind
        source: authz-config.json
        target: /etc/authservice/config.json

Note: You need to create the envoy-config.yaml and authz-config.json files in the same directory as the docker-compose.yaml file. You could find the contents of the files in the GitHub repository.

Then you should start the services:

docker-compose up -d

Once your services are up and running, you can access the authservice service by sending a request to the envoy service. The envoy service will forward the request to the authservice service.

curl http://localhost:8080

You should see the response from the authservice service:
