This guide assumes that you already have Postgres running and helps you set up the Hasura GraphQL engine on Kubernetes
|
|
and connect it to your Postgres database.
|
|
|
|
|
|
Step 1: Get the Kubernetes deployment and service files
|
|
-------------------------------------------------------
|
|
|
|
The `hasura/graphql-engine/install-manifests <https://GitHub.com/hasura/graphql-engine/tree/master/install-manifests>`_ repo
|
|
contains all installation manifests required to deploy Hasura anywhere. Get the Kubernetes deployment and service files
|
|
from there:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ wget https://raw.githubusercontent.com/hasura/graphql-engine/master/install-manifests/kubernetes/deployment.yaml
|
|
$ wget https://raw.githubusercontent.com/hasura/graphql-engine/master/install-manifests/kubernetes/svc.yaml
|
|
|
|
Step 2: Set the Postgres database url
|
|
-------------------------------------
|
|
|
|
Edit ``deployment.yaml`` and set the right database url:
|
|
|
|
.. code-block:: yaml
|
|
:emphasize-lines: 4
|
|
|
|
...
|
|
env:
|
|
- name: HASURA_GRAPHQL_DATABASE_URL
|
|
value: postgres://username:password@hostname:port/dbname
|
|
...
|
|
|
|
Examples of ``HASURA_GRAPHQL_DATABASE_URL``:
|
|
|
|
- ``postgres://admin:password@localhost:5432/my-db``
|
|
- ``postgres://admin:@localhost:5432/my-db`` *(if there is no password)*
|
|
|
|
.. note::
|
|
|
|
- If your **password contains special characters** (e.g. #, %, $, @, etc.), you need to URL encode them in the
|
|
``HASURA_GRAPHQL_DATABASE_URL`` env var (e.g. %40 for @).
|
|
|
|
You can check the :doc:`logs <logging>` to see if the database credentials are proper and if Hasura is able
|
|
to connect to the database.
|
|
|
|
- Hasura GraphQL engine needs access permissions to your Postgres database as described in
|
|
:doc:`Postgres permissions <../postgres-permissions>`
|
|
|
|
|
|
Step 3: Create the Kubernetes deployment and service
|
|
----------------------------------------------------
|
|
|
|
.. code-block:: bash
|
|
|
|
$ kubectl create -f deployment.yaml
|
|
$ kubectl create -f svc.yaml
|
|
|
|
Step 4: Open the Hasura console
|
|
-------------------------------
|
|
|
|
The above creates a LoadBalancer type service with port 80. So you should be able to access the console at the
|
|
external IP.
|
|
|
|
For example, using Docker-for-desktop on Mac:
|
|
|
|
.. code-block:: bash
|
|
|
|
$ kubectl get svc
|
|
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
|
|
hasura LoadBalancer 10.96.214.240 localhost 80:30303/TCP 4m
|
|
kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 8m
|
|
|
|
Head to: http://localhost and the console should load!
|
|
|
|
Step 5: Track existing tables and relationships
|
|
-----------------------------------------------
|
|
|
|
See :doc:`../../schema/using-existing-database` to enable GraphQL over the database.
