The main step in connecting Superset to a database is to **install the proper database driver(s)** in your environment. :::note You'll need to install the required packages for the database you want to use as your metadata database as well as the packages needed to connect to the databases you want to access through Superset. For information about setting up Superset's metadata database, please refer to installation documentations ([Docker Compose](/admin-docs/installation/docker-compose), [Kubernetes](/admin-docs/installation/kubernetes)) ::: ## Supported Databases Superset supports **80 databases** with varying levels of feature support. Click on any database name to see detailed documentation including connection strings, authentication methods, and configuration options. ## Installing Database Drivers Superset requires a Python [DB-API database driver](https://peps.python.org/pep-0249/) and a [SQLAlchemy dialect](https://docs.sqlalchemy.org/en/20/dialects/) to be installed for each database engine you want to connect to. ### Installing Drivers in Docker For Docker deployments, create a `requirements-local.txt` file in the `docker` directory: ```bash # Create the requirements file touch ./docker/requirements-local.txt # Add your driver (e.g., for PostgreSQL) echo "psycopg2-binary" >> ./docker/requirements-local.txt ``` Then restart your containers. The drivers will be installed automatically. ### Installing Drivers with pip For non-Docker installations: ```bash pip install ``` See individual database pages for the specific driver packages needed. ## Connecting Through the UI 1. Go to **Settings → Data: Database Connections** 2. Click **+ DATABASE** 3. Select your database type or enter a SQLAlchemy URI 4. Click **Test Connection** to verify 5. Click **Connect** to save ## Contributing To add or update database documentation, add a `metadata` attribute to your engine spec class in `superset/db_engine_specs/`. Documentation is auto-generated from these metadata attributes. See [METADATA_STATUS.md](https://github.com/apache/superset/blob/master/superset/db_engine_specs/METADATA_STATUS.md) for the current status of database documentation and the [README](https://github.com/apache/superset/blob/master/superset/db_engine_specs/README.md) for the metadata schema.
