相关 yaml 资源下载
Bookinfo 应用分为四个单独的微服务：
- productpage：这个微服务会调用 details 和 reviews 两个微服务，用来生成页面
- details：这个微服务中包含了书籍的信息
- reviews：这个微服务中包含了书籍相关的评论。它还会调用 ratings 微服务
- ratings：这个微服务中包含了由书籍评价组成的评级信息
reviews 微服务有 3 个版本：
- v1 版本不会调用 ratings 服务
- v2 版本会调用 ratings 服务，并使用 1 到 5 个黑色星形图标来显示评分信息
- v3 版本会调用 ratings 服务，并使用 1 到 5 个红色星形图标来显示评分信息

查看命名空间资源是否创建成功并正常运行
-
测试 bookinfo 是否运行（只需替换命名空间）
kubectl exec -n mm-xianliu "$(kubectl -n mm-xianliu get pod -l app=ratings -o jsonpath='{.items[0].metadata.name}')" -c ratings -- curl -sS productpage:9080/productpage | grep -o ".* "
输出Simple Bookstore App
外部访问
-
添加网关 gateway 和虚拟服务 vs（注意修改 namespace 和 hosts）
apiVersion: networking.istio.io/v1alpha3 kind: Gateway metadata: name: bookinfo-gateway namespace: mm-xianliu spec: # The selector matches the ingress gateway pod labels. # If you installed Istio using Helm following the standard documentation, this would be "istio=ingress" selector: istio: ingressgateway # use istio default controller servers: - port: number: 8080 name: http protocol: HTTP hosts: - "my.bookinfo.com" --- apiVersion: networking.istio.io/v1alpha3 kind: VirtualService metadata: name: bookinfo namespace: mm-xianliu spec: hosts: - "my.bookinfo.com" gateways: - bookinfo-gateway http: - match: - uri: exact: /productpage - uri: prefix: /static - uri: exact: /login - uri: exact: /logout - uri: prefix: /api/v1/products route: - destination: host: productpage port: number: 9080 -
修改主机 hosts 文件
-
开始测试
curl -s "http://my.bookinfo.com/productpage" | grep -o ".* "
定义服务版本
-
创建目标规则（注意修改 namespace）
apiVersion: networking.istio.io/v1alpha3 kind: DestinationRule metadata: name: productpage namespace: mm-xianliu spec: host: productpage subsets: - name: v1 labels: version: v1 --- apiVersion: networking.istio.io/v1alpha3 kind: DestinationRule metadata: name: reviews namespace: mm-xianliu spec: host: reviews subsets: - name: v1 labels: version: v1 - name: v2 labels: version: v2 - name: v3 labels: version: v3 --- apiVersion: networking.istio.io/v1alpha3 kind: DestinationRule metadata: name: ratings namespace: mm-xianliu spec: host: ratings subsets: - name: v1 labels: version: v1 - name: v2 labels: version: v2 - name: v2-mysql labels: version: v2-mysql - name: v2-mysql-vm labels: version: v2-mysql-vm --- apiVersion: networking.istio.io/v1alpha3 kind: DestinationRule metadata: name: details namespace: mm-xianliu spec: host: details subsets: - name: v1 labels: version: v1 - name: v2 labels: version: v2 ---
