Run Hasura GraphQL engine
|
|
-------------------------
|
|
|
|
Using Hasura Cloud
|
|
^^^^^^^^^^^^^^^^^^
|
|
|
|
Navigate to `cloud.hasura.io
|
|
<https://cloud.hasura.io/signup/?pg=docs&plcmt=body&cta=navigate-to-cloud-hasura-io&tech=default>`__, and
|
|
create a new Hasura Cloud account.
|
|
|
|
Once you create a project on Hasura Cloud, hit the "Launch Console" button
|
|
to open the Hasura Console for your project.

|
|
|
Using docker
|
|
^^^^^^^^^^^^
|
|
Get the Hasura docker-compose file:
|
|
|
|
.. code-block:: bash
|
|
|
|
# in a new directory run
|
|
wget https://raw.githubusercontent.com/hasura/graphql-engine/stable/install-manifests/docker-compose/docker-compose.yaml
|
|
# or run
|
|
curl https://raw.githubusercontent.com/hasura/graphql-engine/stable/install-manifests/docker-compose/docker-compose.yaml -o docker-compose.yaml
|
|
|
|
The following command will run Hasura along with a Postgres database required
|
|
for its functioning.
|
|
|
|
.. code-block:: bash
|
|
|
|
$ docker-compose up -d
|
|
|
|
Check if the containers are running:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ docker ps
|
|
|
|
CONTAINER ID IMAGE ... CREATED STATUS PORTS ...
|
|
097f58433a2b hasura/graphql-engine ... 1m ago Up 1m 8080->8080/tcp ...
|
|
b0b1aac0508d postgres ... 1m ago Up 1m 5432/tcp ...
|
|
|
|
Please do note that you will see a Postgres database running, which is used by Hasura to store its configuration (Hasura metadata).
|
|
|
|
Head to ``http://localhost:8080/console`` to open the Hasura console.
|
|
|
|
|
|
Connecting to a BigQuery project
|
|
--------------------------------
|
|
|
|
Pre-requisites
|
|
^^^^^^^^^^^^^^
|
|
|
|
Hasura GraphQL engine requires the following to connect to a BigQuery project:
|
|
|
|
- `Project Id <https://support.google.com/googleapi/answer/7014113?hl=en>`__
|
|
- The `datasets <https://cloud.google.com/bigquery/docs/datasets-intro>`__ that can be exposed over graphql have to be explicitly listed.
|
|
- A `Service Account <https://cloud.google.com/iam/docs/service-accounts>`__ to query the project.
|
|
|
|
Creating a Service Account
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
- In Google Cloud's console, head to your BigQuery project.
|
|
|
|
- Go to ``IAM & Admin > Service Accounts > Create Service Account``
|
|
|
|
.. thumbnail:: /img/graphql/core/databases/bigquery/1-service-account.png
|
|
:alt: Add source
|
|
:width: 400px
|
|
|
|
|
|
- Give it a name, and under roles, and grant these 3 roles: ``BigQuery Metadata Viewer``, ``BigQuery Data Viewer`` and ``BigQuery Job User``.
|
|
|
|
.. thumbnail:: /img/graphql/core/databases/bigquery/2-service-account-details.png
|
|
:alt: Add source
|
|
:width: 600px
|
|
|
|
- Click on the created service account, ``Keys > ADD KEY > Create New Key > JSON > Create``. This will download a service account file on your computer.
|
|
|
|
Connect BigQuery to Hasura
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
- Update Graphql engine with an environment variable set to the contents of the service account.
|
|
|
|
|
|
For example, this maybe done as follows if you are using docker:
|
|
|
|
.. code-block:: bash
|
|
|
|
docker run -e BIGQUERY_SA_ACCOUNT=$(cat /path/to/the/service-account.json) <rest-of-the-flags>
|
|
|
|
|
|
- Head to the console, in the ``Connect Existing Database`` page, choose ``Environment Variable`` under ``Connect Via``, and fill in the necessary details:
|
|
|
|
.. thumbnail:: /img/graphql/core/databases/bigquery/3-connect-bigquery.png
|
|
:alt: Add source
|
|
:width: 600px
|
|
|
|
You should now be able to track the tables that are part of the specified
|
|
tables and configure relationships between them. As BigQuery lacks
|
|
foreign key constraints, the console cannot suggest relationships, so
|
|
all relationships between BigQuery tables have to be manually configured.
|
|
|
|
Try out a GraphQL query
|
|
-----------------------
|
|
|
|
Head to the ``GraphiQL`` tab in the console and try running a GraphQL query! Use the explorer sidebar on GraphQL to get help in creating a GraphQL query.

|
Keep up to date
|
|
---------------
|
|
|
|
Hasura currently supports queries on BigQuery.
|
|
|
|
Please watch this space to get the latest docs on how you can try these features out via the console or by manipulating metadata in JSON/YAML directly.
|
