服務網格：創建VirtualService（3分）
? 將Bookinfo應用部署到default命名空間下，為Bookinfo應用創建一個名為reviews的VirtualService，要求來自名為Jason的用戶的所有流量將被路由到reviews服務的v2版本。（需要用到的軟件包：ServiceMesh.tar.gz）

# 上傳解壓
tar -xf ServiceMesh.tar.gz# 導入鏡像
docker load -i ServiceMesh/images/image.tar# 初始化Kubernetes集群
init-cluster# 查看集群狀態
kubectl cluster-info# 進入ServiceMesh目錄
cd ServiceMesh/# 執行bookinfo
kubectl apply -f bookinfo/bookinfo.yaml# 查看pops狀態
kubectl gcat bookinfo-gateway.yaml
