 Let us say you are running kener on a subpath `/status`. You can set the base path like this:
 
 ```bash
-docker run \
- -p 3000:3000 \
- -v $(pwd)/uploads:/app/uploads \
- -e "KENER_BASE_PATH=/status" \
- -e "KENER_SECRET_KEY=somesecretkey" \
- -e "DATABASE_URL=mysql://root:password@mysql-container-2.orb.local:3306/kener-2" \
- -e "ORIGIN=https://www.example.com" \
- rajnandan1/kener
+docker build  --build-arg KENER_BASE_PATH=/status -t kener .
+```
+
+```bash
+ docker run  -p 3000:3000 --env-file .env -v $(pwd)/database:/app/uploads -v $(pwd)/database:/app/database kener
