Question

我正在尝试在Docker上运行ASP.NET Core 2.0应用程序（REDIS + RabbitMQ + NGINX）。

当我通过docker-compose上传这些容器时，这些服务可以运行，甚至可以由Windows访问，因为它们由＆＃34; HostPORT：ContainerPORT＆＃34;映射。

但是，在测试应用程序本身时，.NET会在控制台中通知您无法连接到REDIS，例如。

fail: Microsoft.AspNetCore.Server.Kestrel[13]
  Connection id "0HLDGDJNAEB9E", Request id "0HLDGDJNAEB9E:00000001": An unhandled exception was thrown by the application.
  StackExchange.Redis.RedisConnectionException: It was not possible to connect to the redis server(s); to create a disconnected multiplexer, disable AbortOnConnectFail. SocketFailure on PING.

我的docker-compose.yml：

version: '3'

services:
  nginx:
    build:
      dockerfile: ./nginx/nginx.dockerfile
      context: .
    image: nginx
    container_name: nginx
    ports:
      - "80:80"
    networks:
      - production-network
    depends_on:
      - "wordSearcherApp"

  wordSearcherApp:
    image: wordsearcherapplication
    container_name: wordsearcherapp
    build:
      context: .
      dockerfile: WordSearcher/Dockerfile
    networks:
      - production-network
    ports:
      - "61370"
    volumes:
      - repository:/repository
    depends_on:
      - redis
      - rabbit

  redis:
    image: redis
    container_name: redis
    ports:
      - "6379:6379"
    networks:
      - production-network

  rabbit:
    image: rabbitmq
    container_name: rabbitmq
    ports:
      - "5672:5672"
      - "15672:15672"
    networks:
      - production-network
    healthcheck:
      test: ["CMD", "curl", "-f", "http://localhost:15672"]
      interval: 30s
      timeout: 10s
      retries: 5

networks:
  production-network:
    driver: bridge

volumes:
  repository:
    driver: local

对于C＃中的Connection，我使用此connectionString localhost:6379

我该怎么做？感谢。

Answer 1

使用redis:6379代替localhost:6379。

Docker-Compose将使用您为docker-compose.yml文件中的服务定义的名称作为其容器的主机名。

服务不在Docker内部进行通信
