How to create a MongoDB® Database Instance

Managed MongoDB® Databases provide fully-managed document Database Instances, with MongoDB® as a database engine.

Document databases enable users to store and retrieve data in a document format, such as json. Compared to traditional relational databases where data is stored in a table-like format, document-type storage supports storing multiple nested keys and values in each document key.

Before you start

To complete the actions presented below, you must have:

• A Scaleway account logged into the console
• Owner status or IAM permissions allowing you to perform actions in the intended Organization

How to create a database

1. Click MongoDB® under Managed Databases on the side menu, if you do not have a Database Instance already created, the creation page displays.

2. Click Create a Database Instance. The creation wizard displays.

3. Complete the following steps in the wizard:

   • Select MongoDB® as a database engine.
   • Choose a region. This is the geographical location where your database will be deployed.
   • Select a replica set configuration. You can choose between:
     • Replica-set 1-node - an instance of MongoDB® that runs as a single server and does not provide redundancy or high availability.
     • Replica-set 3-nodes - a group of 3 MongoDB® servers (1 primary and 2 standby nodes) that maintain the same data set. Replica sets provide redundancy and high availability and are the basis for all production deployments. If the main node fails for any reason, one of the remaining standby nodes is assigned and can take over requests, reducing downtime.
   • Select a node type.
   • Define the size of your Block Storage volume. You can increase your storage space without changing your node type, with no downtime. You can increase your volume size to up to 10 TB.
   • Add a name and set a password for your user.
   Important

   Your username must adhere to specific criteria.

   • Length must be between 1 and 63 characters
   • First character must be an alphabetic character (a-Za-Z)

   • Only a-zA-Z0-9_$- characters are accepted
   • Enter a name for your Database Instance.
