Docker compose mongo不会创建root用户

Question

I am trying to create to compose a docker container with a mongo image. I want the container to have a root user called admin and also be able to create a database called experts_db . Here is my docker-compose.yaml :

version: '3.7'

services:
    mongodb:
        image: mongo:4.0.4
        container_name: mongodbtest
        restart: always
        env_file: .env
        environment:
            MONGO_INITDB_ROOT_USERNAME: admin
            MONGO_INITDB_ROOT_PASSWORD: 123456789
            MONGO_INITDB_DATABASE: experts_db
        ports:
            - 27017:27017
        volumes:
             - ./mongo-init.js:/docker-entrypoint-initdb.d/mongo-init.js:ro

and here is my mongo-init.js file:

use admin;

db.createUser(
        {
            user: "andrea",
            pwd: "123456789",
            roles: [
                "userAdminAnyDatabase",
                   "dbAdminAnyDatabase",
                   "readWriteAnyDatabase"

            ]
        }
);

Despite that, when I am in the mongo shell and try to get a list of all users, I get the following error:

use experts_db
switched to db experts_db
> db.getUsers()
2020-01-22T14:30:00.569+0000 E QUERY    [js] Error: command usersInfo requires authentication :
_getErrorWithCode@src/mongo/shell/utils.js:25:13
DB.prototype.getUsers@src/mongo/shell/db.js:1763:1
@(shell):1:1

Does anyone know why this happens? I am new to mongo and dont understand how I could fix this

Answer 1

You need to remove the data/db/ volume inside your container then rerun and build again

rm -rf data/db/
docker-compose up --build

Answer 2

I have tested the JS script below and it works as expected:

db.createUser(
{
    user: "aaa",
    pwd: "123",
    roles: [ { role: "readAnyDatabase", db: "admin" }, { role: "dbAdminAnyDatabase", db: "admin" }, { role: "userAdminAnyDatabase", db: "admin" }]
});

After the creation, you can hop on mongoDB shell and run db.getUsers() to make sure the user has been successfully created.
