Docker内部的Mongo身份验证

Question

我正在尝试使用身份验证运行mongo docker映像。遵循文档中最简单的示例，我通过docker-compose up命令运行了mongo和mongo-express图像。我docker-compose.yml现阶段：

version: '3.1'

services:

  mongo:
    image: mongo
    restart: always
    environment:
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: example

  mongo-express:
    image: mongo-express
    restart: always
    ports:
      - 8081:8081
    environment:
      ME_CONFIG_MONGODB_ADMINUSERNAME: root
      ME_CONFIG_MONGODB_ADMINPASSWORD: example

这样运行，两个容器都可以正常运行，我可以从mongo-express网站浏览mongo的内容。但是，每当我更改docker-compose.yml文件名或密码时，例如：

version: '3.1'

services:

  mongo:
    image: mongo
    restart: always
    environment:
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: example123

  mongo-express:
    image: mongo-express
    restart: always
    ports:
      - 8081:8081
    environment:
      ME_CONFIG_MONGODB_ADMINUSERNAME: root
      ME_CONFIG_MONGODB_ADMINPASSWORD: example123

mongo-express抛出未经授权的错误消息：

mongo-express_1  |   code: 13,

无论什么用户名或密码我进入docker-compose.yml，我不能让蒙戈-EXPRESS连接到蒙戈，只有当我使用原始root和example对。

请注意，我没有将用户名和密码用作环境变量，但是可以将它们直接键入docker-compose.yml文件中，如您在此处看到的那样。

还要注意，当我将MONGO_INITDB_ROOT_USERNAMEand MONGO_INITDB_ROOT_PASSWORD（mongo's）变量更改为任何值时，它们似乎都没有作用，我仍然可以使用原始根目录和示例凭据与mongo-express连接。

是什么导致这种行为？我该如何进行这项工作？

Answer 1

对我有用的只是为 mongodb 服务器添加环境变量。

ME_CONFIG_MONGODB_SERVER: mongo

像这样：

version: '3.1'

services:

  mongo:
    image: mongo
    restart: always
    environment:
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: example

  mongo-express:
    image: mongo-express
    restart: always
    ports:
      - 8081:8081
    environment:
      ME_CONFIG_MONGODB_ADMINUSERNAME: root
      ME_CONFIG_MONGODB_ADMINPASSWORD: example
      ME_CONFIG_MONGODB_SERVER: mongo

Answer 2

您docker-compose命令：

docker-compose up --build --force-recreate    

Mongo映像使用匿名卷，因此您还需要--renew-anon-volumes（doc）：

docker-compose up --build --force-recreate --renew-anon-volumes

否则，将使用具有已初始化DB的先前卷=> INITDB env变量将不被使用。
