Failed to set the root user to MongoDB

Question

I have created a MongoDB docker container with the following compose.yaml

---
services:
  mongodb:
    image: "docker.io/library/mongo:7.0.11"
    container_name: mongodb
    restart: unless-stopped
    environment:
      - MONGO_INITDB_ROOT_USERNAME=userAdmin
      - MONGO_INITDB_ROOT_PASSWORD=userPassword
    volumes:
      - "./config/db:/data/db:rw"
      - "./config/configdb:/data/configdb:rw"
    ports:
      - 27017:27017

But I cannot be authenticated with the credential:

# docker exec -it mongodb /bin/bash
root@714f19b7730e:/# mongosh --authenticationDatabase admin -u "userAdmin" -p "userPassword"
Current Mongosh Log ID: 667a13a6a6babd90d5a26a12
Connecting to:      mongodb://<credentials>@127.0.0.1:27017/?directConnection=true&serverSelectionTimeoutMS=2000&authSource=admin&appName=mongosh+2.2.6
MongoServerError: Authentication failed.

And the container logged the following errors:

Answer 1

I have found out the problem is the systemd-nspawn environment messing up the mongo container.

I run the mongo container in another ubuntu machine and it works perfectly.
