Updating Hasura GraphQL engine on Heroku

This guide will help you update Hasura GraphQL engine running on Heroku. This guide assumes that you already have Hasura GraphQL engine running on Heroku.

The current latest version is: hasura/graphql-engine:v1.0.0-beta.2

Follow these steps to update Hasura GraphQL engine to the latest version:

Deploy Straight on Heroku

You can quickly deploy the Hasura app onto your Heroku account by clicking the button below.

Deploy to Heroku



Step 1: Clone the Hasura GraphQL engine Heroku app

The Hasura app with Heroku buildpack/configuration is available at: https://github.com/hasura/graphql-engine-heroku

Clone the above repository.

If you already have this, then pull the latest changes which will have the updated GraphQL engine docker image.

Step 2: Attach your Heroku app

Let’s say your Heroku app is called hasura-heroku and is running on https://hasura-heroku.herokuapp.com.

Use the Heroku CLI to configure the git repo you cloned in Step 1 to be able to push to this app.

# Replace <hasura-heroku> with your Heroku app's name
$ heroku git:remote -a <hasura-heroku>
$ heroku stack:set container -a <hasura-heroku>
