All subsequent Alembic commands must be run from this directory (`/app/backend/open_webui` inside the container or `backend/open_webui` in a local setup), where the `alembic.ini` file is located.

### 2. Check the Current Database Revision
### 2. Set Environment Variables (Docker Only)
:::danger[Critical Step for Docker Users]
When you open a shell in a Docker container with `docker exec`, the application's environment variables are **not** automatically loaded. You must set them manually before running any Alembic commands to avoid errors.
:::
You will need to export the following variables:
1. `PYTHONPATH`: This tells Python where to find the application's modules.
2. `DATABASE_URL`: This is the connection string for your database.
3. `WEBUI_SECRET_KEY`: This is a required variable for the application's authentication system.
You can find the values for `DATABASE_URL` and `WEBUI_SECRET_KEY` in your `docker-compose.yaml` file or the `docker run` command you used to start the container.
Before proceeding, export the variables in your container shell:
```bash
export PYTHONPATH=.:../
export DATABASE_URL="your-database-url-here"
export WEBUI_SECRET_KEY="your-secret-key-here"
```
For example, for a PostgreSQL database, it might look like this:
```bash
export PYTHONPATH=.:../
export DATABASE_URL="postgresql://user:password@host:port/database"
export WEBUI_SECRET_KEY="t0p-s3cr3t"
