=================================

Let's say you have an existing `Heroku Postgres <https://www.heroku.com/postgres>`_ database with data in it, and you'd
|
|
like add GraphQL on it.
|
|
|
|
.. note::
|
|
|
|
In case you're exposing an existing database (esp. if it is production), please configure an access key
|
|
for the console and the GraphQL endpoint.
|
|
|
|
Step 0: Deploy Hasura on Heroku
|
|
-------------------------------
|
|
|
|
Deploy Hasura on Heroku by clicking on this button:

|
|
:class: no-shadow
|
|
:target: https://heroku.com/deploy?template=https://github.com/hasura/graphql-engine-heroku
|
|
|
|
Follow the Heroku instructions to deploy, check if the Hasura console loads up when you **View app** and then head
|
|
to the **Manage App** screen on your Heroku dashboard.
|
|
|
|
Step 1: Remove the existing Postgres addon in the app
|
|
-----------------------------------------------------
|
|
|
|
Head to your Heroku dashboard and delete the Postgres addon:

|
|
|
|
Step 2: Configure environment variables
|
|
---------------------------------------
|
|
|
|
Now configure the ``DATABASE_URL`` with your existing Heroku Postgres database URL and a ``HASURA_GRAPHQL_ACCESS_KEY``
|
|
if you want to secure your endpoint.

|
|
|
|
Step 3: Track tables and relationships
|
|
--------------------------------------
|
|
|
|
Wait for the GraphQL engine to restart and you'll see your existing tables as "untracked tables" in the console.
