云计算-容器云-服务网格Bookinfo

服务网格:创建 Ingress Gateway

将 Bookinfo 应用部署到 default 命名空间下,请为 Bookinfo 应用创建一个网 关,使外部可以访问 Bookinfo 应用。

上传ServiceMesh.tar.gz包

powershell 复制代码
[root@k8s-master-node1 ~]# tar -zxvf ServiceMesh.tar.gz 
[root@k8s-master-node1 ~]# cd ServiceMesh/images/
[root@k8s-master-node1 images]# docker load -i image.tar 
部署Bookinfo应用到kubernetes集群:
[root@k8s-master-node1 images]# cd /root/ServiceMesh/
[root@k8s-master-node1 ServiceMesh]# kubectl apply -f bookinfo/bookinfo.yaml

服务网格:路由管理

将 Bookinfo 应用部署到 default 命名空间下,应用默认请求路由,将所有流 量路由到各个微服务的 v1 版本。然后更改请求路由 reviews,将指定比例的流量 从 reviews 的 v1 转移到 v3。

powershell 复制代码
[root@k8s-master-node1 ServiceMesh]# vim route.yaml
apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: reviews-route
spec:
  hosts: # 将流量路由到指定主机
  - reviews
  http:
  - name: "v1"
    route: # 定义路由转发目的地列表(所有http流量都会被路由到标签为version:v1的reviews服务上)
    - destination:
        host: reviews
        subset: v1
  - name: "v2"
    match:
    - uri:
        prefix: "/wpcatalog"
    - uri:
        prefix: "/consumercatalog"
    rewrite: # 定义重写HTTP URL 或 Authority headers,不能与重定向同时配置,重写操作会在转发前执行
      uri: "/newcatalog"
    route:
    - destination:
        host: reviews
        subset: v2
[root@k8s-master-node1 ServiceMesh]# kubectl apply -f route.yaml
