Getting Started with Hasura and Oracle in Docker


This guide will help you get set up with the Enterprise Edition of Hasura GraphQL Engine with our Oracle integration using Docker Compose. This is the easiest way to set up Hasura Enterprise Edition and the Oracle GraphQL Data Connector.

Supported versions
  1. Hasura GraphQL Engine v2.24.0 onwards
  2. Hasura supports most databases with standard implementations of Oracle 18.0 and higher including Amazon RDS.
Supported features

Hasura currently supports queries, mutations (INSERT, UPDATE, DELETE), table relationships, remote relationships and permissions on Oracle.

Note that Hasura doesn't yet support the ability to modify the database schema for Oracle, so the database you connect to should already contain tables and data. You should also ideally have access to it outside of Hasura to modify the schema.

Deploying Hasura Enterprise with Docker


This tutorial assumes that the following prerequisites have been met:

  • You have Docker and Docker Compose working on your machine.
  • You have access to a Oracle database for which you would like to create an API.

Step 1: Get the Docker Compose file

The install manifests directory contains all installation manifests required to deploy Hasura anywhere. The Docker Compose manifest also contains a Postgres database in order to store the Hasura metadata and a Redis instance for caching.

# in a new directory run
# or run

Step 2: Set the Hasura Enterprise Edition license key and the admin secret

Edit the downloaded docker-compose.yaml and set the license key and admin secret. If you've been provided a license key by the Hasura team, you can enter it according to the directions below.

image: hasura/graphql-engine:v2.24.0

An admin secret key is required to make sure that your GraphQL endpoint and the Hasura Console are not publicly accessible.

I don't have a license key

If you don't already have a license key and are interested in trying out Hasura Enterprise Edition with Oracle, you can start a free 30-day trial. Leave the HASURA_GRAPHQL_EE_LICENSE_KEY environment variable commented out we'll return to this in Step 4.

Secure the admin secret

The HASURA_GRAPHQL_ADMIN_SECRET should never be passed from the client to the Hasura GraphQL Engine as it would give the client full admin rights to your Hasura instance. See Authentication & Authorization for information on setting up auth in Hasura.

Step 3: Run Hasura GraphQL Engine

The following command will create and run the containers in the Docker Compose manifest:

docker compose up -d

Check that the containers are running:

docker ps

097f58433a2b hasura/graphql-engine ... 1m ago Up 1m 8080->8080/tcp ...
b0b1aac0508d postgres ... 1m ago Up 1m 5432/tcp ...
3a29aa348999 redis:7 ... 1m ago Up 1m 6379/tcp ...
7b5b2ee70ece hasura/graphql-data-connector ... 1m ago Up 1m 5005/tcp ..

You can check the health of the connector using the /health endpoint. The connector is available at the following endpoint:

Data connector

This data source utilizes the hasura/graphql-data-connector to connect your data source to the GraphQL engine.

Step 4: Load the Hasura Console

Open the Hasura Console by navigating to http://localhost:8080/console. You will need to input your admin secret key as set in your Docker Compose file to log in.

If you don't already have a license key, you can start a 30-day free trial by clicking the ENTERPRISE button in the top navigation. You can read more details here.

Step 5: Connect to a Oracle database

From the Console, click the Data tab:

Connect database

Select the Oracle data source driver, enter in a display name for the database and set the JDBC Connection URL for your Oracle instance.

The JDBC connection URL should look like this:


For example:

jdbc:oracle:thin:myuser/[email protected]:oracletest # assuming the default port 1521
jdbc:oracle:thin:myuser/[email protected]:1234:oracletest # assuming Oracle is running on port 1234

Click Connect Database.

Ensure your password escapes special characters

Due to the potential variations in drivers, it's crucial to escape special characters used in the password of the connection string. These include { } % & #. To escape a character, use the appropriate escape sequence based on your database's driver's documentation.

Step 6: Track tables and run GraphQL API queries

Now that you have successfully connected your Oracle database to Hasura, you can track tables and use Hasura to automatically build a full-featured GraphQL API for it.

Step 7 (optional): Use managed PostgreSQL and Redis instances

The Hasura Enterprise Edition Docker compose files come with containerized open-source versions of PostgreSQL and Redis.

We highly recommend using managed PostgreSQL and Redis instances especially when running in production.

To switch to using your PostgreSQL or Redis instances, set the following environment variables:


For example:

image: hasura/graphql-engine:v2.24.0
HASURA_GRAPHQL_METADATA_DATABASE_URL: postgres://postgres:postgrespassword@postgres:5432/postgres
HASURA_GRAPHQL_REDIS_URL: 'redis://redis:6379'
