部署bookinfo-gateway
apiVersion: networking.istio.io/v1beta1 kind: Gateway metadata: name: bookinfo-gateway namespace: default spec: selector: istio: ingressgateway servers: - hosts: - ‘*‘ port: name: http number: 80 protocol: HTTP
部署productpage服务的virtualservice，并绑定bookinfo-gateway
apiVersion: networking.istio.io/v1beta1 kind: VirtualService metadata: name: productpage namespace: default spec: gateways: - bookinfo-gateway hosts: - ‘*‘ http: - match: - uri: prefix: /productpage - uri: prefix: /static route: - destination: host: productpage port: number: 9080 timeout: 10s
修改deploy/istio-ingressgateway以使用hostNetwork，通过nodeIp:80端口访问productpage
nodeIp=$(kubectl describe pod istio-ingressgateway -n istio-system | grep ^IP: | awk ‘{print $2}‘)
http://nodeIp/productpage?u=test
不断访问productpage
for i in `seq 1 10000`; do curl -o /dev/null http://nodeIp/productpage?u=test ; done
