### Define RuleSet for Access Control

Source: https://dadrus.github.io/heimdall

Use this Kubernetes custom resource to define access control rules for your services. Specify matching conditions for routes, schemes, and hosts, and define the execution pipeline for authentication and authorization.

```yaml
apiVersion: heimdall.dadrus.github.com/v1alpha4
kind: RuleSet
metadata:
  name: My awesome service
spec:
  rules:
    - id: my_api_rule
      match:
        routes:
          - path: /api/**
        scheme: http
        hosts:
          - type: exact
            value: 127.0.0.1:9090
      execute:
        - authenticator: keycloak
        - authorizer: opa
