如何把ingressgateway和自动生成的virtualservice关联上

[362475097]

想让用户可以使用公网域名，从k8s集群外部访问，有没有ingressgateway配置的示例

搜索Istio Gateway配置就可以了，这种材料网络上比较容易找到

我部署了一个service-a服务，自动生成的virtualservice如下:

apiVersion: networking.istio.io/v1beta1
kind: VirtualService
metadata:
  creationTimestamp: "2022-07-06T08:47:43Z"
  generation: 1
  name: service-a
  namespace: demo
  ownerReferences:
  - apiVersion: env.alibaba.com/v1alpha2
    blockOwnerDeletion: true
    controller: true
    kind: VirtualEnvironment
    name: demo-virtualenv
    uid: 3276e1dc-67b5-473d-b340-ce4eacd98a96
  resourceVersion: "82058"
  uid: 7abd2801-a420-4b2b-ba18-1ee63154f355
spec:
  gateways:
  - mesh
  hosts:
  - service-a
  http:
  - match:
    - headers:
        X-Virtual-Env:
          exact: dev.proj1
      port: 5000
    route:
    - destination:
        host: service-a
        port:
          number: 5000
        subset: dev-proj1
      weight: 100
  - match:
    - port: 5000
    route:
    - destination:
        host: service-a
        port:
          number: 5000
        subset: dev
      weight: 100

现在的疑问是，我想配置ingressgateway，公网域名为www.xxx.com，它无法和自动生成的virtualservice关联上。 现在能想到的是，照着这个virtualservice，再新建一个virtualservice，hosts部分改为www.xxx.com
