I'm using Docker Compose and trying to make two containers talk to each other. One runs a MongoDB database and the other one is a Flask app that needs to read data from the first one using PyMongo.
The Mongo image is defined with the following Dockerfile:
FROM mongo:6.0
ENV MONGO_INITDB_ROOT_USERNAME admin
ENV MONGO_INITDB_ROOT_PASSWORD admin-pwd
ENV MONGO_INITDB_DATABASE admin
COPY mongo-init.js /docker-entrypoint-initdb.d/
EXPOSE 27017
And my data is loaded through the following mongo-init.js script:
db.auth('admin','admin-pwd')
db = db.getSiblingDB('quiz-db')
db.createUser({
user: 'quiz-admin',
pwd: 'quiz-pwd',
roles: [
{
role: 'readWrite',
db: 'quiz-db'
}
]
});
db.createCollection('questions');
db.questions.insertMany([
{
question: "Do you like sushi?",
answers: {
0:"Yes",
1:"No",
2:"Maybe"
}
}
]);
The Flask app is pretty straightforward. I'll skip the Dockerfile for this one as I don't think it's important to the issue. I try to connect to the database with the following code:
from flask import Flask, render_template
from pymongo import MongoClient
app = Flask(__name__)
MONGO_HOST = "questions-db"
MONGO_PORT = "27017"
MONGO_DB = "quiz-db"
MONGO_USER = "quiz-admin"
MONGO_PASS = "quiz-pwd"
uri = "mongodb://{}:{}#{}:{}/{}?authSource=quiz-db".format(MONGO_USER, MONGO_PASS, MONGO_HOST, MONGO_PORT, MONGO_DB)
client = MongoClient(uri)
db=client["quiz-db"]
questions=list(db["questions"].find())
I'm not an expert when it comes to Mongo, but I've set authSource to 'quiz-db' since that's the database where I've created the user in the 'mongo-init.js' script. I tried to run the database container alone and I did successfully log in using mongosh with the user 'quiz-db'. All the data is there and everything works fine.
The problem is only coming up when trying to connect from the Flask app. Here's my Docker compose file:
version: '3.9'
services:
#Flask App
app:
build: ./app
ports:
- "8000:5000"
depends_on:
- "questions-db"
networks:
- mongo-net
#Mongo Database
questions-db:
build: ./questions_db
hostname: questions-db
container_name: questions-db
ports:
- "27017:27017"
networks:
- mongo-net
networks:
mongo-net:
driver: bridge
When I run 'docker compose up' I get the following error on the Flask container startup:
pymongo.errors.OperationFailure: command find requires authentication
full error: {'ok': 0.0, 'errmsg': 'command find requires authentication', 'code': 13, 'codeName': 'Unauthorized'}
MongoDB stores all user credentials in the admin database, unless you are using a really ancient version.
Use authSource=admin in the URI
I'm using https://hub.docker.com/_/mongo mongo image in my local docker environment, but I'm getting Authentication failed error. In docker-compose I add it like:
my-mongo:
image: mongo
restart: always
container_name: my-mongo
environment:
MONGO_INITDB_ROOT_USERNAME: mongo
MONGO_INITDB_ROOT_PASSWORD: asdfasdf
networks:
- mynet
I also tried to run mongo CLI from inside the container but still getting the same error:

After some time, I figured out.
On the same folder, create docker-compose.yml and init-mongo.js
docker-compose.yml
version: '3.7'
services:
database:
image: mongo
container_name : your-cont-name
command: mongod --auth
environment:
- MONGO_INITDB_DATABASE=my_db
- MONGO_INITDB_ROOT_USERNAME=admin
- MONGO_INITDB_ROOT_PASSWORD=root
ports:
- '27017-27019:27017-27019'
volumes:
- mongodbdata:/data/db
- ./init-mongo.js:/docker-entrypoint-initdb.d/mongo-init.js:ro
volumes:
mongodbdata:
driver: local
init-mongo.js
db.createUser(
{
user: "your_user",
pwd: "your_password",
roles: [
{
role: "readWrite",
db: "my_db"
}
]
}
);
db.createCollection("test"); //MongoDB creates the database when you first store data in that database
Auth
First, execute the bash inside the container
docker exec -it your-cont-name bash
Now we can login.
For the admin
mongo -u admin -p root
For the your_user you have to specify the db (with the --authenticationDatabase) otherwise you'll have an auth error
mongo -u your_user -p your_password --authenticationDatabase my_db
After that, you should switch to the right db with
use my_db
If you don't execute this command, you'll be on test db
Note
For being sure of having the right config, i prefer to
docker-compose stop
docker-compose rm
docker volume rm <your-volume>
docker-compose up --build -d
as stated in the Docs
These variables, used in conjunction, create a new user and set that
user's password. This user is created in the admin authentication
database and given the role of root, which is a "superuser" role.
so you need to add --authenticationDatabase admin to your command since the mongod will be started with mongod --auth
example:
mongo -u mongo -p asdfasdf --authenticationDatabase admin
i have the same issue, after google two hours finally sovled;
solution：find out the host machine direcory mounted into mongodb container, delete it,then re-create the mongodb container.
mongo db container create by docker-compose.yaml mount a diretory from host mechine to the container for save the mongo datbases. when you remove the container the mouted direcotry do not deleted, so the default username and password pass by env var could be long time ago you set, now you change the user name and password. just do not work,cause recreate the container will not recreate the "admin" database .
I've fallen in this trap and wasted a day while everything was correct.
I'm writing this for future me(s) because it wasn't mentioned anywhere else and also to avoid my mistake while setting up user/pass combination to connect to their database from other services.
Assuming everything is right:👇
If you are mounting some local folder of yours as storage for your database like below:
services:
your_mongo_db:
// ...some config
volumes:
- ./__TEST_DB_DATA__:/data/db
- ./init-mongo.js:/docker-entrypoint-initdb.d/mongo-init.js:ro
environment:
- "MONGO_INITDB_ROOT_USERNAME=root"
- "MONGO_INITDB_ROOT_PASSWORD=pass"
//...more config
Please remember to remove this folder before re-running your compose file. I think when you run the docker-compose command for the first time, Mongo will create and store the user data there (like any other collections) and then reuse it for the next time (since you mounted that volume).
I had the same problem myself,
Please first remove the username and password from credentials.
environment:
MONGO_INITDB_ROOT_USERNAME: mongo
MONGO_INITDB_ROOT_PASSWORD: asdfasdf
after you remove the credentials you may check dbs or users on your mongodb.
show dbs
show users
Those commands also needs auth, so if you can see them, can be null, then you fix your issue.
Than,
then create a admin user,
use admin
db.createUser({user: "root", pwd: "root", roles:["root"]})
then you can logout and try to connect with credentials to the shell as an admin.
In addition if you are still having some issues about creating new user,
In my case I changed mechanisms to SCRAM-SHA-1 than it worked like a charm.
{
user: "<name>",
pwd: passwordPrompt(), // Or "<cleartext password>"
customData: { <any information> },
roles: [
{ role: "<role>", db: "<database>" } | "<role>",
...
],
authenticationRestrictions: [
{
clientSource: ["<IP>" | "<CIDR range>", ...],
serverAddress: ["<IP>" | "<CIDR range>", ...]
},
...
],
mechanisms: [ "<SCRAM-SHA-1|SCRAM-SHA-256>", ... ],
passwordDigestor: "<server|client>"
}
I had the same problem myself, follows this steps:
Steps 1 and 2 are to delete de old configuration, and set and apply the new configuration, its so important:
Delete to the containers mongo:
docker rm mongo -f
If you have created volumes, delete them:
docker volume rm $(docker volume ls -q) -f
In ports field of docker-compose.yml set:
- 27018:27017 ->
Its so important that ports is not 27017:27017, in my case it was generating conflict.
Up docker compose:
docker-compose up
Try now the connection with authentication!
Example of docker-compose.yml:
mongo:
container_name: mongo
image: mongo:4.4
restart: always
environment:
TZ: "Europe/Madrid"
MONGO_INITDB_ROOT_USERNAME: "user"
MONGO_INITDB_ROOT_PASSWORD: "admin1"
volumes:
- ./mongoDataBase:/data/db
ports:
- 27018:27017
Best regards!
how would you script the Dockerfile to create admin user for mongoDB 4.2 ?
Is there a one line command to create admin users not using an interactive subshell ? (didn't see any in mongoDB documentation)
Thanks for your help.
Passing MONGO_INITDB_ROOT_USERNAME and MONGO_INITDB_ROOT_PASSWORD does not work anymore (removed from Docker hub mongo image documentation).
The mongo Docker hub documentation only shows interactive shell admin user creation.
> mongo admin
executes mongo interactive shell but how do you write a shell script to enter commands in that subshell from the top level shell ?
FROM mongo
RUN mongo admin ???? db.createUser({ user: 'jsmith', pwd: 'some-initial-password', roles: [ { role: "userAdminAnyDatabase", db: "admin" } ] });
The docker build process should display:
Successfully added user: {
"user" : "jsmith",
"roles" : [
{
"role" : "userAdminAnyDatabase",
"db" : "admin"
}
]
}
OK, here's the way to add authetication via the Dockerfile.
create a init.js file:
db = new Mongo().getDB("admin");
// create admin user
db.createUser({
user: "admin",
pwd: "password",
roles: [
{
role: "clusterAdmin",
db: "admin"
}
]
});
// create non admin user
db.createUser({
user: "toto",
pwd: "123",
roles: [
{
role: "readWrite",
db: "tube"
}
]
});
create the Dockerfile:
FROM mongo
# init.js will be executed when the mongo instance runs
COPY ./init.js ./docker-entrypoint-initdb.d
build your docker image
docker build -t mongoAuth .
run the container (attached mode to see the logs)
docker run --name mongoContainer -p 27017:27017 mongoAuth
What I was missing was that I didn't set the database on which to create the users (admin database) by using:
db = new Mongo().getDB("admin");
I'm trying to set up mongo using docker but I don't know the correct way to log in to mongo. It doesn't seem to have created the default root user as I have specified:
version: '3'
services:
location-mongo-db:
container_name: location-mongo-db
image: mongo
ports:
- "27017:27017"
restart: always
environment:
MONGO_INITDB_ROOT_USERNAME: root
MONGO_INITDB_ROOT_PASSWORD: example
networks:
default:
external:
name: environment_location-mongo
I run
docker-compose -f docker-compose/db.yml -p location-mongo-db up -d --build
I then do
docker exec -it location-mongo-db sh
to get in to the shell and run # mongo from inside the container. I get the following:
# mongo
MongoDB shell version v4.0.0
connecting to: mongodb://127.0.0.1:27017

I don't know what the issue is. Here is my output from checking for the list of users:
> db.runCommand({connectionStatus : 1})
{
"authInfo" : {
"authenticatedUsers" : [ ],
"authenticatedUserRoles" : [ ]
},
"ok" : 1
}
What is missing? I've tried signing in a few different ways with -u root and -p etc but nothing so far works
When you start mongo client without params on mongo command, you connect yourself as unauthenticated user, with very limited privileges.
The right command to connect from your docker tty (and from your host terminal since you expose mongodb port) with your root user credentials is :
mongo -u root -p example --authenticationDatabase admin
To fully disable connection without authetication, you need to start mongod process with the --auth option.
EDIT : According to the doc, it seems that with the two env variables MONGO_INITDB_ROOT_USERNAME and MONGO_INITDB_ROOT_PASSWORD set, mongod in docker container must start with --auth option automatically... but this behavior is not working for me.
I'm trying to create a user in mongo who can do anything in any db.
According to the guide I created a new admin: http://docs.mongodb.org/manual/tutorial/add-user-administrator
This is the code:
use admin
db.addUser( { user: "try1",
pwd: "hello,
roles: [ "userAdminAnyDatabase" ] } )
Then I stopped mongo, enabled the auth and restarted mongo.
Then I tried to create a database with his user.
According with this guide: http://www.mkyong.com/mongodb/how-to-create-database-or-collection-in-mongodb/
use fragola
db.users.save( {username:"fragolino"} )
And I get this: "not authorized for insert on fragola.users"
Anyone can help me?
from docs.mongodb.org-superuser-roles
Lets write answer that looks simple & also simple to implement
Steps :
1 : sudo apt-get install mongodb-org - in new terminal
2 : sudo mongod --port 27017 --dbpath /var/lib/mongodb
3 : mongo --port 27017 - in new terminal
4 : use admin
5 : As #drmirror said a user should have all 4 roles to be superuser
For Mongo Version 2.
db.createUser(
{
user: "tom",
pwd: "jerry",
roles: [
{ role: "userAdminAnyDatabase", db: "admin" },
{ role: "readWriteAnyDatabase", db: "admin" },
{ role: "dbAdminAnyDatabase", db: "admin" },
{ role: "clusterAdmin", db: "admin" }
]
})
For Mongo Version 3.
db.createUser(
{
user: "tom",
pwd: "jerry",
roles:["root"]
})
6 : sudo /etc/init.d/mongod stop OR sudo service mongod stop - in new terminal
7 : sudo /etc/init.d/mongod start OR sudo service mongod start
8 : restart your pc
9 : sudo mongod --auth --port 27017 --dbpath /var/lib/mongodb - in new terminal
10: mongo --port 27017 -u "tom" -p "jerry" --authenticationDatabase "admin" - in new terminal
Note : step 10 is most important step .
it will give Output on terminal like
MongoDB shell version: 2.6.11
connecting to: 127.0.0.1:27017/test

The role userAdminAnyDatabase gives the user the ability to create users and assign arbitrary roles to them. Because of this, that user has the power to do anything on the database, because he can give anybody any permission (including himself).
However, the userAdminAnyDatabase role by itself doesn't allow the user to do anything else besides assigning arbitrary rights to arbitrary users. To actually do something on the database, that user needs to have the following additional roles:
readWriteAnyDatabase
dbAdminAnyDatabase
clusterAdmin
A user who has the above three rights and userAdminAnyDatabase is a true super-user and can do anything.
