Question

我之前有一个问题（至少我认为），当我设法解决出现的错误时，它或多或少变得无用了。但是，我的新错误是，我似乎无法从内部连接到mongodb我的泊坞窗图片

docker-compose.yml：

version: '3.1'
services:
  company-repo-docker-app:
    image: company-repo-image
    build:
        context: ./
    dockerfile: Dockerfile
    depends_on:
        - mongo
ports:
    - 8080:8080
mongo:
image: mongo
ports:
  - '27017:27017'
networks:
  mongo_net:
    ipv4_address: 172.28.0.2

networks:
  mongo_net:
    driver: bridge
    ipam:
      driver: default
      config:
      -
       subnet: 172.28.0.2/24

application.properties：

spring.data.mongodb.database=myDb
spring.data.mongodb.host=172.28.0.2 
spring.data.mongodb.port=27017

以及实际错误：

 com.mongodb.MongoSocketOpenException: Exception opening socket

Answer 1

您已在docker-compose.yml文件中明确创建了一个网络，并将数据库设置为使用该网络。 Docker Compose还会为您创建一个默认网络，并且由于您的应用程序未明确声明任何网络，因此它仅附加到默认网络。然后，这两个容器位于不同的网络上，而一个无法到达另一个。

这里最简单的解决方案是删除所有手动网络配置：

version: '3.1'
services:
  company-repo-docker-app:
    image: company-repo-image
    build:
      context: ./
    depends_on:
      - mongo
    ports:
      - '8080:8080'
  mongo:
    image: mongo
    ports:
      - '27017:27017'

服务块的名称将是有效的DNS主机名，在您的配置中，您可以设置spring.data.mongodb.host=mongo。

Answer 2

我同意David的回答是正确的。但是这里有个要点，您的配置也可以，我尝试了我的示例，这是结果。

问题是您的应用未连接到网络。

    @Bean
    public SecurityWebFilterChain securityWebFilterChain(ServerHttpSecurity http, RoleHierarchy roleHierarchy() {
        return http
            .csrf().disable()
            .formLogin().disable()
            .httpBasic().disable()
            .authenticationManager(reactiveAuthenticationManager)
            .securityContextRepository(securityContextRepository)
            .authorizeExchange()
                .pathMatchers("/user/**").access(new CustomReactiveAuthorizationManager<>("USER", roleHierarchy))
            .anyExchange().permitAll()
            .and()
            .logout().disable()
            .build();
    }

样本docker-compose.yml

services:
  company-repo-docker-app:
    image: company-repo-image
    build:
        context: ./
    dockerfile: Dockerfile
    depends_on:
        - mongo
    ports:
     - 8080:8080
    networks:
     - mongo_net

mongo容器ip地址：

version: '3.1'
services:
  mongo-app:
    image: barath-mongo
    ports:
      - "9000:9000"
    depends_on:
      - mongo
    environment:     
      SPRING_DATA_MONGODB_PORT: 27017
      SPRING_DATA_MONGODB_HOST: 172.28.0.2 
      SPRING_DATA_MONGODB_DATABASE: myDb
    networks:
      - mongo_net
  mongo:
    image: mongo
    ports:
    - '27017:27017'
    networks:
     mongo_net:
        ipv4_address: 172.28.0.2
networks:
  mongo_net:
    driver: bridge
    ipam:
      driver: default
      config:
      -
       subnet: 172.28.0.2/24

docker网络设置

$ docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' ec2-user_mongo_1
172.28.0.2

无法连接到mongo容器
