如何在Kubernetes中使用Istio Ingress转发RabbitMQ的STOMP协议

Question

我尝试了这个Gateway和VirtualService，但都不起作用。

apiVersion: networking.istio.io/v1alpha3
kind: Gateway
metadata:
name: stomp
spec:
selector:
istio: ingressgateway
servers:
- port:
number: 80
name: stomp
protocol: TCP
hosts:
- rmq-stomp.mycompany.com

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
name: rmq-stomp
spec:
hosts:
- rmq-stomp.mycompany.com
gateways:
- stomp
http:
- match:
- uri:
prefix: /
route:
- destination:
port:
number: 61613
host: rabbitmq.default.svc.cluster.local

服务没有问题，因为当我试图从其他吊舱连接时，它已经连接好了。

使用tcp.match，而不是http.match。以下是我在istio-gateway文档和istio-virtualservice-dosc中找到的示例

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
name: bookinfo-mongo
namespace: bookinfo-namespace
spec:
hosts:
- mongosvr.prod.svc.cluster.local # name of internal Mongo service
gateways:
- some-config-namespace/my-gateway # can omit the namespace if gateway is in same namespace as virtual service.
tcp:
- match:
- port: 27017
route:
- destination:
host: mongo.prod.svc.cluster.local
port:
number: 5555

所以你看起来像

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
name: rmq-stomp
spec:
hosts:
- rmq-stomp.mycompany.com
gateways:
- stomp
tcp:
- match:
- port: 80
route:
- destination:
host: rabbitmq.default.svc.cluster.local
port:
number: 61613
