Connecting Hasura to an Aiven Postgres Database
This guide explains how to connect a new or existing Aiven Postgres database to a Hasura instance, either on Hasura Cloud or via one of our self-hosted solutions. 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.
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:
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 Postgres DB on Aiven
If you have an existing Aiven Postgres database, you can skip this step and move on to step 4.
Log into the Aiven console.
On the Aiven console, click
+ Create a new service:
Scroll down and select the
Service Plan based on your requirements.
In the end, enter a
Name for the 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
Services dashboard, click on your DB:
Scroll down to
Allowed IP Addresses and click on
If you're using Hasura Cloud, you can quickly find your IP address from the
Hasura Cloud IP field on the project's
If you're using a self-hosted solution, you'll need to determine the IP address manually depending on your hosting service.
Add the Hasura IP address that you copied, click on the
Then click on
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
Step 6: Finish connecting the database
Back on the Hasura Console, enter the database URL that we retrieved in step 5:
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.
