Environment

dubbo: 3.2.0-beta.5 jdk: 1.8 k8s: 1.25.2 istio: 1.17.1

Steps to reproduce this issue

  1. 按照官方示例（https://cn.dubbo.apache.org/zh-cn/overview/tasks/mesh/proxyless/） 搭建了测试环境。
  2. 使用了官方测试demo（https://github.com/apache/dubbo-samples/tree/master/3-extensions/registry/dubbo-samples-xds） ，修改dubbo版本到3.2.0-beta.5。
  3. 在k8s中部署了两个版本（v1与v2）的provider以及一个consumer。
  4. 使用的路由配置如下所示： image

Expected Behavior

v1版本的pod接收全部consumer流量，v2版本pod没有流量。

Actual Behavior

v1与v2版本流量均有流量，流量路由功能未生效。

请问出现这个问题的原因可能有哪些呢？是dubbo版本问题？或者是路由配置问题？

目测跟xds router有关，我来看看吧

补充一下provider的报警信息：

2023-03-14T01:21:19.436Z | INFO:  [DUBBO] No value is configured in the registry, the DynamicConfigurationFactory extension[name : xds] does not support as the config center, dubbo version: 1.0-SNAPSHOT, current host: 10.244.0.139
2023-03-14T01:21:19.436Z | Mar 14, 2023 1:21:19 AM org.apache.dubbo.config.deploy.DefaultApplicationDeployer info
2023-03-14T01:21:19.436Z | INFO:  [DUBBO] The registry[<dubbo:registry address="xds://istiod.istio-system.svc:15012" protocol="xds" port="15012" />] will be not used as the config center, dubbo version: 1.0-SNAPSHOT, current host: 10.244.0.139
2023-03-14T01:21:19.638Z | Mar 14, 2023 1:21:19 AM org.apache.dubbo.config.context.ConfigManager info

下面是我的dubbo配置：

dubbo.application.name=dubbo-samples-xds-provider
dubbo.application.metadataServicePort=20885
dubbo.application.metadataServiceProtocol=dubbo
dubbo.registry.address=xds://istiod.istio-system.svc:15012
dubbo.protocol.name=tri
dubbo.protocol.port=50051
dubbo.application.qosEnable=true
dubbo.application.qosAcceptForeignIp=true

看起来像是dubbo并没有把istio控制面识别为注册中心，而且识别出dubbo版本是1.0-SNAPSHOT，但是我pom里配的确实是3.2.0-beta.5，我的配置哪里有问题吗？

之前测试使用的路由配置host有问题，没有加namespace，所以路由功能没有生效，按照下面的配置修改后又重新做了测试：

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: dubbo-xds-test-vs
  namespace: dubbo-demo
spec:
  hosts:
    - dubbo-samples-xds-provider.dubbo-demo.svc.cluster.local
  http:
    - route:
        - destination:
            host: dubbo-samples-xds-provider.dubbo-demo.svc.cluster.local
            subset: v1
            port:
              number: 50051
          weight: 50
        - destination:
            host: dubbo-samples-xds-provider.dubbo-demo.svc.cluster.local
            subset: v2
            port:
              number: 50051
          weight: 50

    - name: v1
      labels:
        version: v1
    - name: v2
      labels:
        version: v2

调用provider直接失败，报错信息如下：

看起来像是通过路由配置找到注册的provider示例，但是我这边确实能查到启动的两个provider实例：

# kubectl describe svc dubbo-samples-xds-provider -n dubbo-demo

proxyless功能没问题的

aamingaa commented 1 year ago

我弄了一个能跑通的proxyless流量路由的脚本文件，你对照一下？https://github.com/apache/dubbo/actions/runs/4498349215/jobs/7914994051?pr=11859 。另外dubbo的grpc version要改成1.41.0，然后打个包，在dubbo-samples里引入

@Silocean 请问一下后来调通了吗？是怎么解决的？

服务网格: Proxy模式与Proxyless模式的Dubbo应用，可以互联互通？ @AlbumenJ

背景

想打通测试环境和本地开发环境的流量路由标签的环境隔离，充分利用稳定的测试环境，避免多套环境和维护成本。

Proxy模式与Proxyless模式的Dubbo应用，可以互联互通。 如官方架构图，Sidecar 与 Proxyless 模式共存
