Learn how to configure your PostgreSQL instance to accept incoming connections.
Managed Databases (also called 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.
- a Public Cloud project in your OVHcloud account
- access to the OVHcloud Control Panel
- a PostgreSQL database running on your OVHcloud Cloud Databases (this guide can help you to meet this requirement)
Configure your PostgreSQL instance to accept incoming connections
Before making a connection, we must verify that our PostgreSQL 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 under Databases & Analytics and select your PostgreSQL instance.
Step 1: Verify your user roles and password
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.
This first user avnadmin comes with the following privileges:
LOGIN NOSUPERUSER INHERIT CREATEDB CREATEROLE REPLICATION
We rely on official PostgreSQL roles and privileges. You can manage them yourself via CLI or code. So far, user grants and privileges management are not supported via the OVHcloud Control Panel or the OVHcloud API.
Please read the official PostgreSQL documentation to select the right roles for your use case.
To reset the avnadmin password, click on the more options
... to the right of the user, then on
Reset the password.
To create a new user, click on
Add User, fill out the form, and click the
Create User button.
Once created or updated, the user has to be ready and have the status "Enabled" in the Control Panel.
Step 2: Authorize incoming connections from the PostgreSQL client
In this step, select the
Authorized IPs tab (Access Control List). By default, a Cloud Database does not accept any form of connection from the outside world. This way we can help prevent intrusive connection attempts.
Click to authorize a new IP, and enter the IP of your pgAdmin environment. In our case, we will enter 10.0.0.0/16.
