Cloud: Using Hasura Cloud with a GCP Postgres database
This guide explains how to connect a new or existing GCP 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:
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 2: Create a Postgres DB on GCP (skip if you have an existing DB)
Log into the GCP console.
On the left-side navigation, scroll down to
Storage and click on
On the top, click on
Select an instance ID, as well as a default user password. If required, choose a specific region and zone.
Step 3: Allow connections to your DB from Hasura Cloud
On the dashboard of your GCP database instance, on the left sidebar, click on
Connections. Then scroll down to the
Public IP, and click
+ Add network:
You can choose an optional name (e.g. "Hasura").
Copy the IP address from the copy icon in the
Hasura Cloud IP field on the project's details view on Hasura Cloud.
Enter the Hasura IP address that you copied:
If you're using a database user other than the default one, make sure to give it the right Postgres permissions.
Step 4: Construct the database connection URL
The structure of the database connection URL looks as follows:
user-name: If you have a separate database user, the user name will be their name. If you didn't specify a user, the default user name is
password: If you have a separate database user, use their password. Otherwise, use the password that you chose when creating the database.
public-ip: The public IP can be optained by clicking on
Overviewon the left-side navigation and then scrolling down to
Connect to this instance:
postgres-port: The default port for Postgres is
5432if not specified otherwise.
db: The DB is
postgresby default unless otherwise specified.
Step 5: Finish connecting the database
Back on Hasura Console, enter the database URL that we retrieved in step 4:
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.
Step 6 (optional): Enable SSL connection
Step 6.1 Get GCP SSL Certs
Google Cloud (GCP) SQL makes the following SSL/TLS certificates available for download:
- A server certificate saved as
- A client public key certificate saved as
- A client private key saved as
Note Please refer to the
Google Cloud Documentation for detailed information about the different certs.
Download these certs to your local drive.
Step 6.2: Add env vars
Log in to Hasura Cloud, go to your project and add the following env vars:
(Open the cert files using your favourite text editor, select all the contents and copy them to the clipboard)
|Env Var Name||Value|
|Contents from |
|Contents from |
|Contents from |
Here is how your Hasura Cloud env vars setup should look like:
Step 6.3: Configure SSL settings
Open the console of your Hasura Cloud project, go to the
Data -> Manage -> [db-name] -> Edit page.
Connection Settings add the following SSL certificate settings:
Here is how the setup should look like:
Finally, click on the
Update Connection button to apply the SSL settings.
