我有以下脚本指定了自定义数据库，但我没有看到在 GUI(指南针)中创建数据库用户。我只看到 3 个默认数据库(admin、config、local)。

我调查过这个 linked请回答，但我需要一个具体的答案来回答我的问题。

mongo:
    image: mongo:4.0.10
    container_name: mongo
    restart: always
    environment:
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: mypass
      MONGO_INITDB_DATABASE: mydb
    ports:
      - 27017:27017
      - 27018:27018
      - 27019:27019

1. 期望创建用户数据库。
2. 数据库预先填充了一些记录。

编辑 - 取得了一些进展，2 个问题

增加的体积

mongo:
  image: mongo:4.0.1r0
  container_name: mongo
  restart: always
  volumes:
    - ./assets:/docker-entrypoint-initdb.d/

<强>1。忽略

在 assets 文件夹中，我有 3 个文件，我在日志中看到了这个，我的文件被忽略了。

/usr/local/bin/docker-entrypoint.sh: ignoring /docker-entrypoint-initdb.d/file1.json

/usr/local/bin/docker-entrypoint.sh: ignoring /docker-entrypoint-initdb.d/file2.json

/usr/local/bin/docker-entrypoint.sh: ignoring /docker-entrypoint-initdb.d/file3.json

我所有的 JSON 文件如下所示。 (没有根数组对象？根没有 [] 吗？)

{ "_id" : { "$oid" : "5d3a9d423b881e4ca04ae8f0" }, "name" : "Human Resource" }
{ "_id" : { "$oid" : "5d3a9d483b881e4ca04ae8f1" }, "name" : "Sales" }

<强>2。未创建默认数据库。以下行没有任何效果。

MONGO_INITDB_DATABASE: mydb

最佳答案

所有 *.json 扩展名的文件将被忽略，它应该在 *.js 中。查看 mongo DB 的文档 docker hub

MONGO_INITDB_DATABASE

This variable allows you to specify the name of a database to be used for creation scripts in /docker-entrypoint-initdb.d/*.js (see Initializing a fresh instance below). MongoDB is fundamental designed for "create on first use", so if you do not insert data with your JavaScript files, then no database is created.

初始化新实例

When a container is started for the first time it will execute files with extensions .sh and .js that are found in /docker-entrypoint-initdb.d. Files will be executed in alphabetical order. .js files will be executed by mongo using the database specified by the MONGO_INITDB_DATABASE variable, if it is present, or test otherwise. You may also switch databases within the .js script.

你可以看看这个例子

创建文件夹data并将create_article.js放入其中

(在示例中我将传递您创建的数据库用户)

db = db.getSiblingDB("user");
db.article.drop();

db.article.save( {
    title : "this is my title" , 
    author : "bob" , 
    posted : new Date(1079895594000) , 
    pageViews : 5 , 
    tags : [ "fun" , "good" , "fun" ] ,
    comments : [ 
        { author :"joe" , text : "this is cool" } , 
        { author :"sam" , text : "this is bad" } 
    ],
    other : { foo : 5 }
});

db.article.save( {
    title : "this is your title" , 
    author : "dave" , 
    posted : new Date(4121381470000) , 
    pageViews : 7 , 
    tags : [ "fun" , "nasty" ] ,
    comments : [ 
        { author :"barbara" , text : "this is interesting" } , 
        { author :"jenny" , text : "i like to play pinball", votes: 10 } 
    ],
    other : { bar : 14 }
});

db.article.save( {
    title : "this is some other title" , 
    author : "jane" , 
    posted : new Date(978239834000) , 
    pageViews : 6 , 
    tags : [ "nasty" , "filthy" ] ,
    comments : [ 
        { author :"will" , text : "i don't like the color" } , 
        { author :"jenny" , text : "can i get that in green?" } 
    ],
    other : { bar : 14 }
});

挂载data目录

docker run --rm -it  --name some-mongo -v /home/data/:/docker-entrypoint-initdb.d/  -e MONGO_INITDB_DATABASE=user     -e MONGO_INITDB_ROOT_USERNAME=root     -e MONGO_INITDB_ROOT_PASSWORD=mypass  mongo:4.0.10

创建容器后，您将能够看到数据库，

关于mongodb - 创建 mongodb 数据库并通过 docker-compose 用一些数据填充它，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/57212690/
