Using Hasura Cloud with a Timescale Postgres database¶

Introduction¶

This guide explains how to connect a new or existing Timescale Postgres database to a Hasura Cloud project.

Step 0: Sign up or log in to Hasura Cloud¶

Navigate to Hasura Cloud and sign up or log in.

Step 1: 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 2: Create a Postgres DB on Timescale (skip if you have an existing DB)¶

Log into the Timescale Cloud portal.

On the Timescale dashboard, under Services, click on + Create new service:

Select the Postgres option:

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

In the end, enter a Name for the service:

Then click Create service.

Step 3: Allow connections to your DB from Hasura Cloud¶

On the Services dashboard, click on your DB:

Scroll down to Allowed IP Addresses and click on Change:

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

Add the Hasura IP address that you copied, click on the + and then click on Save changes:

Step 4: Get the database connection URL¶

The structure of the database connection URL looks as follows:

postgresql://<user-name>:<password>@<public-ip>:<postgres-port>/<db>

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

Step 5: Finish connecting the database¶

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

Then click Connect Database.

Voilà. You are ready to start developing.

You can also click the gear icon to manage your Hasura Cloud project. (e.g. add collaborators, env vars or custom domains) and add an admin secret to make sure that your GraphQL endpoint and the Hasura console are not publicly accessible.
