MONGO_INITDB_ROOT_USERNAME not working with nanoserver image

[hatzhang]

The sample stack.yml works with linux.

version: '3.1'
services:
  mongo:
    image: mongo
    restart: always
    environment:
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: example

But if i change image to nanoserver, and run it under windows, authentication error will occur.

version: '3.1'
services:
  mongo:
    image: mongo:nanoserver
    restart: always
    environment:
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: example
    ports:
      - 27017:27017

On client side:

MongoDB.Driver.MongoAuthenticationException
Unable to authenticate using sasl protocol mechanism SCRAM-SHA-1.

On server side:

"error":"UserNotFound: Could not find user "root" for db "test""}}

So is there a way to specify username/password for nanoserver image?

By environment variables, no. You'd have to add --auth to the mongod flags and then docker exec in to then create the first user (since you have to connect via localhost, not a docker port proxy).

$ docker run -d --name some-mongo mongo:6-nanoserver mongod --auth --bind_ip_all
