Connecting Hasura to a Yugabyte Postgres Database
Introduction
This guide explains how to connect a new or existing Yugabyte Postgres database to a Hasura instance, either on Hasura Cloud or via one of our self-hosted solutions. If you're exploring Yugabyte Postgres 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:
You will get prompted for a Postgres Database URL. We will create this in the next step and then come back here.
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:
Step 3: Create a Postgres DB on Yugabyte
Log into the Yugabyte Cloud dashboard.
On the Yugabyte Cloud dashboard, click on Create a free cluster:
Select the Managed Free option and then click Next.
Select a Cloud Provider and Region and then click Next.
If you're using a database user other than the default one, make sure to give it the right Postgres permissions.
Download your credentials and then click Create Cluster.
Step 4: Allow connections to your DB from Hasura
From the cluster's dashboard, click Add IP Allow List:
Within the modal, click Create New List and Add to Cluster:
If using Hasura Cloud, from your project's dashboard, copy the Hasura Cloud IP address:
If you're using a self-hosted solution, you'll need to determine the IP address manually depending on your hosting service.
Then click Save.
Step 5: Construct the database connection URL
The structure of the database connection URL looks as follows:
postgresql://<user-name>:<password>@<public-ip>:<postgres-port>/<db>?ssl=true&sslmode=require
To get it, from the cluster's dashboard, click Run your own application:
Click the Optimize for Hasura Cloud checkbox and then copy your connection string:
Step 6: Finish connecting the database
Back on the Hasura Console, enter the database URL that we just copied and replace the <DB USER> and <DB PASSWORD>
with the information from your credentials downloaded in step 3:
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.
