Connecting Hasura to an Azure Cosmos DB for PostgreSQL


This guide explains how to connect a new Azure Cosmos DB for PostgreSQL to a Hasura instance, either on Hasura Cloud or via one of our self-hosted solutions. If you're exploring Azure Cosmos DB for PostgreSQL, check out their docs before continuing below.


If you plan on using Hasura Cloud, which we recommend, follow steps 1 and 2 below. If you're self-hosting a Hasura instance and already have a project running, skip to step 3.

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 the Data tab and choose Connect Existing Database. Hasura will prompt you for a Postgres Database URL. We'll create this in the next step and then come back here.

Step 3: Create a Cosmos DB on Azure

You can start a free trial with Azure Cosmos DB. Select Azure Cosmos DB for PostgreSQL and click Create:

Create Azure Cosmos

After signing up, you're redirected to your database's home on your Azure portal.

Step 4: Get the connection string

The structure of the database connection URL looks as follows:


Be sure to update the password for the database before continuing. You can do this by clicking on the banner at the top of the page.

Click Connection strings in the side navigation:

Azure Cosmos DB Dashboard

Copy the value labeled as PostgreSQL connection URL.

Step 5: Finish connecting the database

Back on the Hasura Console, enter the database URL that we retrieved in step 4:

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.
