If you install the Azure Aplication Gateway Ingress Controller for your AKS clusters you may want to expose more than one service through the same Public IP just changing the url path. In order to make this work you must use the backend-path-prefix annotation.
In the following sample I create an ingress with the following behavior:
- Calls to http://[Waf Pulic IP or DNS]/inventory are sent to the inventory service
- Calls to http://[Waf Pulic IP or DNS]/orders are sent to the orders service
--- apiVersion: extensions/v1beta1 kind: Ingress metadata: name: backend-ingress annotations: # Service are serving content in this path. appgw.ingress.kubernetes.io/backend-path-prefix: "/" kubernetes.io/ingress.class: azure/application-gateway spec: rules: - http: paths: - path: /inventory/* backend: serviceName: inventory servicePort: 80 - path: /orders/* backend: serviceName: orders servicePort: 80
Note that the appgw.ingress.kubernetes.io/backend-path-prefix value is set to: / which means that the paths specified in the rules are rewritten to this value qhen sent to your services.
Hope it helps.
