## Full Reset 🚫➡️✅

The following environment variables need to be defined for successful operation:

- `DB_ROOT_PASSWORD`: The root password for the MariaDB instance

To completely reset Friendica, including its database and volumes, run:
```bash
docker exec -i central-mariadb mariadb -u root -p"${DB_ROOT_PASSWORD}" -e "DROP DATABASE IF EXISTS friendica; CREATE DATABASE friendica;"
docker compose down
rm -rv /mnt/hdd/data/docker/volumes/friendica_data
docker volume rm friendica_data
```

## Reset Database 🗄️

## Manual Method:

   DROP DATABASE friendica;
   CREATE DATABASE friendica;
   exit;
   ```

## Automatic Method:
