This guide will help you update the Hasura GraphQL engine running on Heroku. This guide assumes that you already have a
|
|
Hasura GraphQL engine running on Heroku.
|
|
|
|
The current latest version is:
|
|
|
|
.. raw:: html
|
|
|
|
<code>hasura/graphql-engine:<span class="latest-release-tag">latest</span></code>
|
|
|
|
Follow these steps to update Hasura GraphQL engine to the lastest version:
|
|
|
|
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``.
|
|
|
|
Navigate to your project directory, use the `Heroku CLI <https://devcenter.heroku.com/articles/heroku-cli>`_ to configure the git repo you cloned in Step 1
|
|
to be able to push to this app.
|
|
|
|
.. code-block:: bash
|
|
|
|
# Replace <hasura-heroku> with your Heroku app's name
|
|
$ heroku git:remote -a <hasura-heroku>
|
|
$ heroku stack:set container -a <hasura-heroku>
|
|
|
|
You can find your Heroku git repo in your Heroku - Settings - Info - Heroku Git URL
|
|
|
|
Step 3: **git push** to deploy the latest Hasura GraphQL engine
|
|
---------------------------------------------------------------
|
|
|
|
When you ``git push`` to deploy, the Heroku app will get updated with the latest changes:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ git push heroku master
|
|
|
|
Deploy a specific version of the Hasura GraphQL engine
|
|
------------------------------------------------------
|
|
|
|
Head to the ``Dockerfile`` in the git repo you cloned in step 1.
|
|
Change the ``FROM`` line to the specific version you want. A list of all releases can be found
|
|
at https://github.com/hasura/graphql-engine/releases.
|
|
|
|
.. code-block:: Dockerfile
|
|
:emphasize-lines: 1
|
|
|
|
FROM hasura/graphql-engine:v1.0.0-alpha01
|
|
|
|
...
|
|
...
|
|
|
|
Change ``v1.0.0-alpha01`` to ``v1.0.0-alpha02`` for example, and then ``git push heroku master`` to deploy.
|
|
|
|
.. note::
|
|
|
|
If you are downgrading to an older version of the GraphQL engine you might need to downgrade your metadata catalogue version
|
|
as described in :doc:`../downgrading` |
