Find out how to configure your M3db instance to accept incoming connections
Last updated 12th May 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 M3db instance to accept incoming connections.
Requirements
- A Public Cloud project in your OVHcloud account
- Access to the OVHcloud Control Panel
- A M3db database running on your OVHcloud Public Cloud Databases (this guide can help you to meet this requirement)
Instructions
Configure your M3db instance to accept incoming connections
Before making a connection, we need to verify that our M3db 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 M3db 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.
You can add more users by clicking on the button Add user.
Enter a username (required) and a group (optional), then click Create User.
You can delete a user or regenerate a password via the ... button in the Users & Roles table.
Step 2: Authorise incoming connections from the M3db client
For security reasons the default network configuration doesn't allow any incoming connections. It is thus critical you authorise the suitable IP addresses in order to successfully access your database.
In this step, select the Authorised IPs tab. IP addresses must be authorised here before they can connect to your database.
Clicking on Add an IP address or IP address block (CIDR) opens a new window in which you can add single IP addresses or blocks to allow access to the database.
You can edit and retract database access via the ... button in the IP table.
If you want to allow connections from the outside, you can enter the IP 0.0.0.0/0. Please use it carefully.
