docker-compose - Zipkin 跟踪不适用于 docker-compose 和 Dapr

Question

应该由 dapr 运行时发送到 zipkin 服务器的跟踪以某种方式无法到达它。
情况如下:
我在 Windows PC 上使用 Docker 桌面。我已经从 dapr 存储库( https://github.com/dapr/samples/tree/master/hello-docker-compose )下载了示例，它与 docker-compose up 完美地开箱即用。
然后我根据 dapr 文档添加了 Zipkin 支持:

在 docker-compose.yml 的底部添加了这个服务

  zipkin:
    image: "openzipkin/zipkin"
    ports:
      - "9411:9411"
    networks:
      - hello-dapr 

在组件文件夹中添加了 config.yaml

apiVersion: dapr.io/v1alpha1
kind: Configuration
metadata:
  name: daprsystem
spec:
  mtls:
    enabled: false
  tracing:
    enabled: true
    exporterType: zipkin
    samplingRate: "1"
    expandParams: true
    includeBody: true
    zipkin:
      endpointAddress: "http://zipkin:9411/api/v2/spans"    

当应用程序运行时，它应该向服务器发送跟踪，但在 zipkin UI 和日志中找不到任何内容。
奇怪的事情开始出现在 nodeapp-dapr_1 服务的日志中: 从客户端证书读取 spiffe id 时出错

pythonapp-dapr_1  | time="2021-03-15T19:14:17.9654602Z" level=debug msg="found mDNS IPv4 address in cache: 172.19.0.7:34549" app_id=pythonapp instance=ce32220407e2 scope=dapr.contrib type=log ver=edge
nodeapp-dapr_1    | time="2021-03-15T19:14:17.9661792Z" level=debug msg="error while reading spiffe id from client cert: unable to retrieve peer auth info. applying default global policy action" app_id=nodeapp instance=773c486b5aac scope=dapr.runtime.grpc.api type=log ver=edge
nodeapp_1         | Got a new order! Order ID: 947
nodeapp_1         | Successfully persisted state.

附加信息 - 当前使用的 dapr 版本是 1.0.1。我确保在配置文件中禁用了安全性 (mtls)。

Answer 1

配置文件应该在不同的文件夹中然后 components .

创建新文件夹，例如dapr旁边components文件夹。

搬家 components文件夹到新创建的 dapr文件夹。

然后创建config.yaml在 dapr文件夹。

相应地更新 docker-compose。

docker-compose

services:
  nodeapp-dapr:
    image: "daprio/daprd:edge"
    command: ["./daprd",
     "-app-id", "nodeapp",
     "-app-port", "3000",
     "-placement-host-address", "placement:50006",
     "-dapr-grpc-port", "50002",
     "-components-path", "/dapr/components",
     "-config", "/dapr/config.yaml"]
    volumes:
      - "./dapr/components/:/dapr"
    depends_on:
      - nodeapp
    network_mode: "service:nodeapp"

配置文件

apiVersion: dapr.io/v1alpha1
kind: Configuration
metadata:
  name: daprConfig
spec:
  mtls:
    enabled: false
  tracing:
    enabled: true
    samplingRate: "1"
    expandParams: true
    includeBody: true
    zipkin:
      endpointAddress: http://host.docker.internal:9411/api/v2/spans

I had issue with localhost and 127.0.0.1 in URL which I resolved using host.docker.internal as hostname.

PS:别忘了全部杀掉 *-dapr_1容器，以便它可以加载新配置。
