aku

API gateway that aggregates multiple backend services behind a single endpoint. You define which APIs to expose using Kubernetes custom resources (declarative configuration), following a domain-oriented microservice style.

Install

1. Install the Aku CRD

   kubectl apply -f artifacts/crd-aku.yaml

2. Create an Aku resource

   kubectl apply -f artifacts/aku.yaml

   Example aku.yaml:

   apiVersion: configuration.aku.vn/v1alpha1
   kind: Aku
   metadata:
     name: aku
   spec:
     deploymentName: aku
     replicas: 1
     routeMap:
       - name: open-prefix-public-path
         overridePath: /api/v1/your-service/public
         upstream_path: /public
       - name: open-prefix/user-path
         overridePath: /api/v1/your-service/user
         upstream_path: /user
     methodMap:
       - name: open-only-public-method
         proto_service: pb.ProtoService
         allow:
           - PublicMethod
       - name: open-all-method-except-private
         proto_service: pb.OtherProtoService
         disallow:
           - PrivateMethod

3. Deploy the aku gateway and assign it a ClusterRole so it can watch Aku resources.
