Well-known

A tiny service collecting and aggregating well-known data from Services and Ingresses in the same Kubernetes namespace. The data is merged and exposed as a JSON object.

Installation

See the Helm chart documentation.

Usage

Add an annotation to a Service or Ingress:

annotation	path
well-known.stenic.io/[path]	/.well-known/[path]

Example

Annotations with the same path are merged across all Services and Ingresses in the namespace.

apiVersion: v1
kind: Service
metadata:
  name: auth-service
  annotations:
    well-known.stenic.io/openid-configuration: |
      {"issuer": "https://auth.example.com", "authorization_endpoint": "https://auth.example.com/authorize"}

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: api-ingress
  annotations:
    well-known.stenic.io/openid-configuration: |
      {"token_endpoint": "https://auth.example.com/token"}

The resulting endpoint contains the merged data from both resources:

curl http://[ingress]/.well-known/openid-configuration

{
    "issuer": "https://auth.example.com",
    "authorization_endpoint": "https://auth.example.com/authorize",
    "token_endpoint": "https://auth.example.com/token"
}
