Deploying to Heroku
===================
1. Log into Heroku using the `Heroku CLI <https://devcenter.heroku.com/articles/heroku-cli>`_:
.. code-block:: bash
# If you have multiple Heroku accounts, use flag '--interactive' to switch between them
heroku login --interactive
2. Create a new Heroku app using the PostgREST buildpack:
.. code-block:: bash
mkdir ${YOUR_APP_NAME}
cd ${YOUR_APP_NAME}
git init .
heroku apps:create ${YOUR_APP_NAME} --buildpack https://github.com/PostgREST/postgrest-heroku.git
heroku git:remote -a ${YOUR_APP_NAME}
3. Create a new Heroku PostgreSQL add-on attached to the app and keep notes of the assigned add-on name (e.g. :code:`postgresql-curly-58902`) referred later as ${HEROKU_PG_DB_NAME}
.. code-block:: bash
heroku addons:create heroku-postgresql:standard-0 -a ${YOUR_APP_NAME}
# wait until the add-on is available
heroku pg:wait -a ${YOUR_APP_NAME}
4. Create the necessary user roles according to the
`PostgREST documentation <https://postgrest.org/en/stable/auth.html>`_:
.. code-block:: bash
heroku pg:credentials:create --name api_user -a ${YOUR_APP_NAME}
# use the following command to ensure the new credential state is active before attaching it
heroku pg:credentials -a ${YOUR_APP_NAME}
heroku addons:attach ${HEROKU_PG_DB_NAME} --credential api_user -a ${YOUR_APP_NAME}
5. Connect to the PostgreSQL database and create some sample data:
.. code-block:: bash
heroku psql -a ${YOUR_APP_NAME}
.. code-block:: postgres
# from the psql command prompt execute the following commands:
create schema api;
create table api.todos (
id serial primary key,
done boolean not null default false,
task text not null,
due timestamptz
);
insert into api.todos (task) values
('finish tutorial 0'), ('pat self on back');
grant usage on schema api to api_user;
grant select on api.todos to api_user;
6. Create the :code:`Procfile`:
.. code-block:: bash
web: PGRST_SERVER_HOST=0.0.0.0 PGRST_SERVER_PORT=${PORT} PGRST_DB_URI=${PGRST_DB_URI:-${DATABASE_URL}} ./postgrest-${POSTGREST_VER}
..
Set the following environment variables on Heroku:
.. code-block:: bash
heroku config:set POSTGREST_VER=10.0.0
heroku config:set PGRST_DB_SCHEMA=api
heroku config:set PGRST_DB_ANON_ROLE=api_user
..
PGRST_DB_URI can be set if an external database is used or if it's different from the default Heroku DATABASE_URL. This latter is used if nothing is provided.
POSTGREST_VER is mandatory to select and build the required PostgREST release.
See https://postgrest.org/en/stable/configuration.html#environment-variables for the full list of environment variables.
7. Build and deploy your app:
.. code-block:: bash
git add Procfile
git commit -m "PostgREST on Heroku"
git push heroku master
..
Your Heroku app should be live at :code:`${YOUR_APP_NAME}.herokuapp.com`
8. Test your app
From a terminal display the application logs:
.. code-block:: bash
heroku logs -t
..
From a different terminal retrieve with curl the records previously created:
.. code-block:: bash
curl https://${YOUR_APP_NAME}.herokuapp.com/todos
..
and test that any attempt to modify the table via a read-only user is not allowed:
.. code-block:: bash
curl https://${YOUR_APP_NAME}.herokuapp.com/todos -X POST \
-H "Content-Type: application/json" \
-d '{"task": "do bad thing"}'
