MongoDB - Configurez votre instance MongoDB pour accepter les connexions entrantes (EN)

Last updated 27^th July 2022

Objective

Public Cloud Databases allow you to focus on building and deploying cloud applications while OVHcloud takes care of the database infrastructure and maintenance in operational conditions.

This guide explains how to configure your MongoDB instance to accept incoming connections.

Requirements

• A Public Cloud project in your OVHcloud account
• Access to the OVHcloud Control Panel
• A MongoDB database running on your OVHcloud Public Cloud Databases (this guide can help you to meet this requirement)

Instructions

Configure your MongoDB instance to accept incoming connections

Before making a connection, we need to verify that our MongoDB instance is correctly configured.

Log in to your OVHcloud Control Panel and open your Public Cloud project. Click on Databases in the left-hand navigation bar and select your MongoDB instance.

Step 1: Verify your user roles and password

Select the Users tab. Verify that you have a user with sufficient rights and a configured password. If you don't remember the user's password, you can either create a new user or regenerate the password of an existing user. Be careful! By doing so you will need to update all the places where you already use this user/password pair.

We provide official MongoDB built-in roles. Please read the official MongoDB documentation to select the right roles for your use case.

In our example, we will create a user called user with the roles readWriteAnyDatabase and userAdminAnyDatabase.

Once created or updated, note the password then after a few seconds check to verify the user is ready and with the "Enabled" status in the OVHcloud Control Panel.

Step 2: Authorise incoming connections from the MongoDB client

In this step, select the Authorised IP's tab (Access Control List). By default, a Public Cloud Database does not accept any form of connection from the outside world. This way we can help prevent intrusive connection attempts.

Click to authorise a new IP. In our case we will enter 109.190.200.59:

Get your connection information (URI)

Select the General Information tab. In the Login Information section, copy the Service URI.

You can specify the MongoDB connection string using either:

• the Standard Connection String Format (service: mongodb).
• the DNS Seed List Connection Format (service: mongodbSrv).

mongodb://<username>:<password>@<hostname>/admin?tls=true

mongodb://<username>:<password>@<hostname node1>,<hostname node 2>,<hostname node 3>/admin?replicaSet=replicaset&tls=true

mongodb+srv://<username>:<password>@mongodb-d5674315-o2626ab53.database.cloud.ovh.net/admin?replicaSet=replicaset

Select the Users tab to get the username or reset a user password.
