Mongodb MongoExpress展会；无法读取属性'；列表数据库'；“未定义”的定义；错误

我尝试使用docker compose.yml创建Mongo和Mongo Express服务器。这是我的背景

version: "3"
services:
  mongo:
    image: "mongo:3-stretch"
    environment:
      - MONGO_INITDB_ROOT_USERNAME=devroot
      - MONGO_INITDB_ROOT_PASSWORD=devroot
      - MONGO_INITDB_DATABASE=DataBank
    ports:
       - "27017:27017"
  mongo-express:
    image: "mongo-express:latest"
    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=devroot
      - ME_CONFIG_MONGODB_AUTH_PASSWORD=devroot
      - ME_CONFIG_OPTIONS_EDITORTHEME=ambiance
      - ME_CONFIG_BASICAUTH_USERNAME=dev
      - ME_CONFIG_BASICAUTH_PASSWORD=dev
    depends_on:
      - mongo
    ports:
      - "8081:8081"

结果（此处有错误）：

尽管出现了第一个错误，我仍然能够访问，但成功登录后，它显示（另一个错误）：

我应该看什么？

这里的问题是mongo express无法访问管理数据库。将这些环境变量添加到mongo express应该可以解决您的问题

- ME_CONFIG_MONGODB_ENABLE_ADMIN=true
- ME_CONFIG_MONGODB_ADMINUSERNAME=${MONGO_ROOT_USER}
- ME_CONFIG_MONGODB_ADMINPASSWORD=${MONGO_ROOT_PASSWORD}

我的最终docker compose文件如下所示，它适合我

version: '3.3' # specify docker-compose version

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=true
      - ME_CONFIG_MONGODB_ADMINUSERNAME=${MONGO_ROOT_USER}
      - ME_CONFIG_MONGODB_ADMINPASSWORD=${MONGO_ROOT_PASSWORD}
      - 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

注意：请不要在生产中使用此功能。

默认的mongo root用户/密码是什么？

- ME_CONFIG_MONGODB_ENABLE_ADMIN=true
- ME_CONFIG_MONGODB_ADMINUSERNAME=${MONGO_ROOT_USER}
- ME_CONFIG_MONGODB_ADMINPASSWORD=${MONGO_ROOT_PASSWORD}

version: '3.3' # specify docker-compose version

services:

    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=true
      - ME_CONFIG_MONGODB_ADMINUSERNAME=${MONGO_ROOT_USER}
      - ME_CONFIG_MONGODB_ADMINPASSWORD=${MONGO_ROOT_PASSWORD}
