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

开始部署

  • 创建 yaml 文件，注意修改 service、serviceaccount 和 deployment 的 namespace

  • 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 "<title>.*</title>"

    输出 <title>Simple Bookstore App</title> 表示正常

外部访问

  • 添加网关 gateway 和虚拟服务 vs（注意修改 namespace 和 hosts）

    yaml 复制代码 
    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 "<title>.*</title>"

定义服务版本

  • 创建目标规则（注意修改 namespace）

    yaml 复制代码 
    apiVersion: networking.istio.io/v1alpha3

  namespace: mm-xianliu
