istio多主集群架构验证方法

istio单网格多集群架构搭建完成后，需要验证下当前集群是否可以发现对端集群，验证方法如下：

命名空间建议设置为：demo-dubbo

deploy.yaml

apiVersion: apps/v1
kind: Deployment
metadata:finalizers:- kubebuilder.io/net.trafficlabels:app: helloworldversion: v1name: helloworld-v1namespace: demo-dubbo

svc.yaml

apiVersion: v1
kind: Service
metadata:labels:app: helloworldname: helloworldnamespace: demo-dubbo
spec:ipFamilies:- IPv4ipFamilyPolicy: SingleStackports:- name: http-http-http-httpport: 5000protocol: TCPtargetPort: 5000- name: http-http-endport: 6000protocol: TCPtargetPort: 6000selector:app: helloworldsessionAffinity: Nonetype: ClusterIP

配置完成后，最好重启应用pod和istiod、东西向网关。

=======================================================

以下内容可忽略：

vs和dr可以不配置

vs.yaml

apiVersion: networking.istio.io/v1beta1
kind: VirtualService
metadata:annotations:manager: kubebuilder.io/net.trafficname: helloworldnamespace: demo-dubbo
spec:http:- name: cap-baselineroute:- destination:host: helloworld.demo-dubbo.svc.cluster.localsubset: cap-baseline

dr.yaml

apiVersion: networking.istio.io/v1beta1
kind: DestinationRule
metadata:name: helloworldnamespace: demo-dubbo
spec:host: helloworld.demo-dubbo.svc.cluster.localsubsets:- labels:version: v1name: cap-baseline- labels:version: v1name: v1

在两个集群的相同命名空间下分别apply如上yaml。
