Using Hasura Cloud with an Aiven Postgres Database

Available on: Cloud


This guide explains how to connect a new or existing Aiven Postgres database to a Hasura Cloud project. If you're exploring Aiven and are interested in migrating an existing Postgres database - such as from Heroku - check out their docs before continuing below.

Step 1: Sign up or log in to Hasura Cloud

Navigate to Hasura Cloud and sign up or log in.

Step 2: Create a Hasura Cloud project

On the Hasura Cloud dashboard, create a new project:

Create Hasura Cloud project

After the project is initialized successfully, click on Launch console to open the Hasura console in your browser.

On the Hasura console, navigate to Data -> Manage -> Connect Database -> Connect existing database:

You will get prompted for a Postgres Database URL. We will create this in the next step and then come back here.

Step 3: Create a Postgres DB on Aiven (skip if you have an existing DB)

Log into the Aiven console.

On the Aiven console, click + Create a new service:

Create a new service on Aiven

Select Postgres:

Select Postgres on Aiven

Scroll down and select the Cloud Provider, Region and Service Plan based on your requirements.

In the end, enter a Name for the service:

Create a service on Aiven

Then click Create service.


If you're using a database user other than the default one, make sure to give it the right Postgres permissions.

Step 4: Allow connections to your DB from Hasura Cloud

On the Services dashboard, click on your DB:

Select DB on Aiven

Scroll down to Allowed IP Addresses and click on Change:

Change allowed IP addresses on Aiven

Copy the IP address from the copy icon in the Hasura Cloud IP field on the project's details view on Hasura Cloud.

Hasura Cloud IP field

Add the Hasura IP address that you copied, click on the +:

Add the Hasura IP on Aiven

Then click on Save changes.

Step 5: Get the database connection URL

The structure of the database connection URL looks as follows:


To get it, navigate to the Overview tab of your database dashboard and copy the Service URI:

Copy the service URI on Aiven

Step 6: Finish connecting the database

Back on Hasura Console, enter the database URL that we retrieved in step 5:

Database setup

Then click Connect Database.


For security reasons, it is recommended to set database URLs as env vars and using the env vars to connect to the databases in place of the raw database URLs.

Voilà. You are ready to start developing.
