MySQL is missing from the connection options because the required driver is not installed in your Docker image. Starting with Superset 4.1.0, database drivers like MySQL are no longer included by default—you need to add them yourself for MySQL support to appear in the UI reference.
To fix this:
1. Create a file called requirements-local.txt in your docker directory (if it doesn’t exist).
2. Add either mysqlclient or mysql-connector-python to that file.
3. Rebuild your Docker image and restart Superset.
Example:
echo "mysqlclient" >> docker/requirements-local.txt
docker compose build --force-rm
docker compose up
If you get errors about missing system dependencies (like default-libmysqlclient-dev), you’ll need to create a custom Dockerfile that installs those before the Python package reference.
If MySQL still doesn’t show up, check your Superset logs for any errors about missing MySQL drivers and share them here for more help.
