如何使用docker-compose运行MongoDB和Mongo-express？

Question

我尝试通过Docker-compose运行MongoDB和Mongo-express.我使用以下配置:

version: '3'

services:
    mongo:
        image: mongo
        environment:
            - MONGO_INITDB_ROOT_USERNAME=${MONGO_ROOT_USER}
            - MONGO_INITDB_ROOT_PASSWORD=${MONGO_ROOT_PASSWORD}
            - MONGO_INITDB_DATABASE=project
    mongo-express:
        image: mongo-express
        environment:
            - ME_CONFIG_MONGODB_SERVER=mongo
            - ME_CONFIG_MONGODB_PORT=27017
            - ME_CONFIG_MONGODB_ENABLE_ADMIN=false
            - ME_CONFIG_MONGODB_AUTH_DATABASE=admin
            - ME_CONFIG_MONGODB_AUTH_USERNAME=${MONGO_ROOT_USER}
            - ME_CONFIG_MONGODB_AUTH_PASSWORD=${MONGO_ROOT_PASSWORD}
            - ME_CONFIG_BASICAUTH_USERNAME=${MONGOEXPRESS_LOGIN}
            - ME_CONFIG_BASICAUTH_PASSWORD=${MONGOEXPRESS_PASSWORD}
        depends_on:
            - mongo
        ports:
          - "8080:8081"

和.env文件:

MONGO_ROOT_USER=devroot
MONGO_ROOT_PASSWORD=devroot
MONGOEXPRESS_LOGIN=dev
MONGOEXPRESS_PASSWORD=dev

在docker-compose upmongo-service运行之后,mongo-express失败了.我在日志中看到错误:

mongo-express_1  | Welcome to mongo-express
mongo-express_1  | ------------------------
mongo-express_1  | Mongo Express server listening at http://0.0.0.0:8081
mongo-express_1  | Server is open to allow connections from anyone (0.0.0.0)
mongo-express_1  | Database connected
mongo-express_1  | Connecting to admin...
mongo-express_1  | TypeError: db is not a function
mongo-express_1  |     at /node_modules/mongo-express/lib/db.js:114:53
mongo-express_1  |     at Array.forEach (native) 

我做错了什么？谢谢你提前!

它适用于我的 Mac。如果您删除 docker-compose 容器并重建，也许它会起作用。我添加了我的文件。只有我改变了 mongo-express 端口。

.env

MONGO_ROOT_USER=devroot
MONGO_ROOT_PASSWORD=devroot
MONGOEXPRESS_LOGIN=dev
MONGOEXPRESS_PASSWORD=dev

docker-compose.yml

version: '3'

services:
    mongo:
        image: mongo
        environment:
            - MONGO_INITDB_ROOT_USERNAME=${MONGO_ROOT_USER}
            - MONGO_INITDB_ROOT_PASSWORD=${MONGO_ROOT_PASSWORD}
            - MONGO_INITDB_DATABASE=project
    mongo-express:
        image: mongo-express
        environment:
            - ME_CONFIG_MONGODB_SERVER=mongo
            - ME_CONFIG_MONGODB_PORT=27017
            - ME_CONFIG_MONGODB_ENABLE_ADMIN=false
            - ME_CONFIG_MONGODB_AUTH_DATABASE=admin
            - ME_CONFIG_MONGODB_AUTH_USERNAME=${MONGO_ROOT_USER}
            - ME_CONFIG_MONGODB_AUTH_PASSWORD=${MONGO_ROOT_PASSWORD}
            - ME_CONFIG_BASICAUTH_USERNAME=${MONGOEXPRESS_LOGIN}
            - ME_CONFIG_BASICAUTH_PASSWORD=${MONGOEXPRESS_PASSWORD}
        depends_on:
            - mongo
        ports:
          - "8888:8081"

当您的数据库使用卷配置，但 mongodb 和 mongo-express 不共享网络配置时，就会出现此问题。这对我来说非常有效：

version: "3.7"

services:
  db:
    container_name: mongo-dev
    image: mongo:4.2
    environment:
      - MONGO_INITDB_ROOT_USERNAME=admin
      - MONGO_INITDB_DATABASE=auth
      - MONGO_INITDB_ROOT_PASSWORD=pass
    networks: 
      - mongo-compose-network
    ports:
      - '27017:27017'
    volumes: 
      - ./data:/data/db
  
  mongo-express:
    container_name: mongo-express
    image: mongo-express
    depends_on:
      - db
    networks: 
      - mongo-compose-network
    environment:
      - ME_CONFIG_MONGODB_SERVER=mongo-dev
      - ME_CONFIG_MONGODB_ADMINUSERNAME=admin
      - ME_CONFIG_MONGODB_ADMINPASSWORD=pass
      - ME_CONFIG_BASICAUTH_USERNAME=admin
      - ME_CONFIG_BASICAUTH_PASSWORD=tribes
    ports:
      - '8081:8081'
    volumes: 
      - ./data:/data/db      

networks:
  mongo-compose-network:
    driver: bridge

新版本的 mongo-express 进行了一些更新，已接受的解决方案不再有效，特别是您需要修复此问题

TypeError: Cannot read property 'listDatabases' of undefined

尖端

请记住，如果您调整设置，请使用选项重新启动它--force-recreate。

docker-compose up --force-recreate -d

这是我当前使用的 docker-compose.yml 。

version: '3'

services:
    mongo:
        image: mongo:${MONGO_TAG}
        environment:
            - MONGO_INITDB_ROOT_USERNAME=${MONGO_ROOT_USER}
            - MONGO_INITDB_ROOT_PASSWORD=${MONGO_ROOT_PASSWORD}
            - MONGO_INITDB_DATABASE=project
    mongo-express:
        image: mongo-express
        environment:
            - ME_CONFIG_MONGODB_SERVER=mongo
            - ME_CONFIG_MONGODB_PORT=27017
            - ME_CONFIG_MONGODB_ENABLE_ADMIN=true
            - ME_CONFIG_MONGODB_AUTH_DATABASE=admin
            - ME_CONFIG_MONGODB_ADMINUSERNAME=${MONGO_ROOT_USER}
            - ME_CONFIG_MONGODB_ADMINPASSWORD=${MONGO_ROOT_PASSWORD}
            - ME_CONFIG_BASICAUTH_USERNAME=${MONGOEXPRESS_LOGIN}
            - ME_CONFIG_BASICAUTH_PASSWORD=${MONGOEXPRESS_PASSWORD}
        links:
            - mongo
        ports:
          - "8081:8081"
