Deploying Hasura GraphQL engine on Koyeb

Introduction

This guide explains how to deploy the Hasura GraphQL engine on the Koyeb Serverless Platform.

Prerequisites

To successfully follow and complete this guide, you need:

• A PostgreSQL database to use as the Hasura GraphQL engine backend.
• A Koyeb account to deploy and run the Hasura GraphQL engine.

Deploy Hasura GraphQL engine on Koyeb

To deploy the Hasura GraphQL engine on Koyeb, we use the hasura/graphql-engine Docker image.

On the Koyeb control panel, click the Create App button. You land on the Koyeb App creation form.

1. Fill the Docker image field with hasura/graphql-engine.

2. In the Ports section, change the export port from 80 to 8080, which is the port the hasura/graphql-engine Docker image app is listening on. This setting is required to let Koyeb know which port your application is listening to and properly route incoming HTTP requests. If you want the Hasura GraphQL engine to be available on a specific path, you can change the default one (/) to the path of your choice.

3. In the Environment variables section, configure the environment variables required to properly run the Hasura GraphQL engine.

   • HASURA_GRAPHQL_DATABASE_URL: The environment variable containing the PostgreSQL URL, i.e. postgres://<user>:<password>@<host>:<port>/<database>. To store this value which contains sensitive information, we strongly recommend configuring the environment variable using Koyeb secrets instead of storing it as a plaintext value. Secrets are encrypted at rest. They are ideal to store sensitive data like API keys, OAuth tokens, etc.
   • HASURA_GRAPHQL_ENABLE_CONSOLE: Set to true. This will expose and allow you to access the Hasura console.
   • HASURA_GRAPHQL_ADMIN_SECRET: The secret to access the Hasura Graphql admin. As for the HASURA_GRAPHQL_DATABASE_URL, we strongly recommend using a secret to store this value.

4. Give your App a name, i.e hasura-demo, and click Create App.

The deployment should be up and running in a few seconds.

Access the Hasura console

Once your Koyeb App is deployed, you can click the App link in the Koyeb control panel to access the Hasura console.

https://<your-app-name>-<your-org-name>.koyeb.app/

At any time, you can track your Hasura service status in the Koyeb control panel and visualize the Hasura GraphQL engine web service logs in the Logs tab of your service.
