部署istio的ingressGateway时，

把istio的IngressGateway理解为 k8s的ingressController

把Gateway理解为 k8s的ingress规则

将k8s的Service通过VirtualService映射到Gateway

apiVersion: networking.istio.io/v1alpha3
kind: Gateway
metadata:
name: test-gateway
namespace: test
spec:
selector:
istio: ingressgateway # use istio default controller
servers:

• port:
  number: 80
  name: http
  protocol: HTTP
  hosts:
  • "*"

通过 DestinationRule 来定义不同版本，在istio称为 子集subsets。

apiVersion: networking.istio.io/v1alpha3
kind: DestinationRule
metadata:
name: test-destinationrule
namespace: test
spec:
host: test-service
trafficPolicy:
tls:
mode: ISTIO_MUTUAL
subsets:

• name: v1
  labels:
  version: v1
• name: v2
  labels:
  version: v2
