多协议管理

更新时间：2024-09-04

概述

本节介绍服务网格CSM支持Dubbo、bRPC等私有协议的相关操作。

使用前提

创建独立网格实例，并且开启支持兼容三方协议按钮。

创建实例

按以下步骤在控制台上创建独立网格实例并且开启多协议支持：

登录百度智能云控制台，选择“产品服务 > 云原生 > 服务网格 CSM”；
在全局概览页面通过“创建实例”按钮进入实例创建页面；
在创建服务网格页面，完成基础配置；
查看网络列表，如下所示：

部署应用

按一下步骤在CCE集群部署应用：

在CSM/注入配置处，给default命名空间开启自动注入；
通过CSM页面跳转到CCE集群，部署应用；
在工作负载/无状态部署新建测试应用。

测试应用的Yaml文件如下所示：

工作负载如下所示：
在CSM/Istio资源管理处下发destinationrule规则。
destinationrule的Yaml文件如下所示：

apiVersion: networking.istio.io/v1alpha3
kind: DestinationRule
metadata:
  name: dubbo-sample-provider
spec:
  host: dubbo-sample-provider.default.svc.cluster.local
  subsets:
  - name: v1
    labels:
      version: v1
  - name: v2
    labels:
      version: v2

流量验证

通过CCE集群中的工作负载查看业务容器中的日志：

从日志中可以得知，consumer请求provider-demo,轮询调用v1与v2版本，符合预期。
从CSM/Istio资源管理处下发流量治理策略，全部访问v1版本。

apiVersion: metaprotocol.aeraki.io/v1alpha1
kind: MetaRouter
metadata:
  name: test-metaprotocol-dubbo-route
spec:
  hosts:
    - dubbo-sample-provider.default.svc.cluster.local
  routes:
    - name: v1
      match:
        attributes:
          interface:
            exact: org.apache.dubbo.samples.basic.api.DemoService
          method:
            exact: sayHello
          foo:
            exact: bar
      route:
        - destination:
            host: dubbo-sample-provider.default.svc.cluster.local
            subset: v1
