 # Managing File Permissions for NetAlertX on Nginx with Docker
 
+> [!TIP]
+> If you are facing permission issues, try to start the container without mapping your volumes. If that works, then the issue is permission related. You can try e.g., the following command: 
+>  ``` 
+>  docker run -d --rm --network=host \
+>  -e TZ=Europe/Berlin \
+>  -e PORT=20211 \
+>  jokobsk/netalertx:latest
+> ```
 NetAlertX runs on an Nginx web server. On Alpine Linux, Nginx operates as the `nginx` user (user ID 101, group ID 82 - `www-data`). Consequently, files accessed or written by the NetAlertX application are owned by `nginx:www-data`.
 
 Upon starting, NetAlertX changes the ownership of files on the host system mapped to `/app/config` and `/app/db` in the container to `nginx:www-data`. This ensures that Nginx can access and write to these files. Since the user in the Docker container is mapped to a user on the host system by ID:GID, the files in `/app/config` and `/app/db` on the host system are owned by a user with the same ID and GID (ID 101 and GID 82). On different systems, this ID:GID may belong to different users (on Debian, the user with ID 82 is `uuidd`), or there may not be a user with ID 82 at all.
