The [Qbittorrent](https://www.qbittorrent.org/) project aims to provide an open-source software alternative to µTorrent. qBittorrent is based on the Qt toolkit and libtorrent-rasterbar library.
We utilise the docker manifest for multi-platform awareness. More information is available from docker [here](https://github.com/docker/distribution/blob/master/docs/spec/manifest-v2-2.md#manifest-list) and our announcement [here](https://blog.linuxserver.io/2019/02/21/the-lsio-pipeline-project/).
Simply pulling `lscr.io/linuxserver/qbittorrent:latest` should retrieve the correct image for your arch, but you can also pull specific arch images via tags.
This image provides various versions that are available via tags. Please read the descriptions carefully and exercise caution when using unstable or development tags.
The webui is at `<your-ip>:8080` and the default username/password is `admin/adminadmin`.
Change username/password via the webui in the webui section of settings.
### WEBUI_PORT variable
Due to issues with CSRF and port mapping, should you require to alter the port for the webui you need to change both sides of the -p 8080 switch AND set the WEBUI_PORT variable to the new port.
For example, to set the port to 8090 you need to set -p 8090:8090 and -e WEBUI_PORT=8090
This should alleviate the "white screen" issue.
If you have no webui , check the file /config/qBittorrent/qBittorrent.conf
If you are running a very old (3.x) kernel you may run into [this issue](https://github.com/linuxserver/docker-qbittorrent/issues/103) which can be worked around using [this method](https://github.com/linuxserver/docker-qbittorrent/issues/103#issuecomment-831238484)
Containers are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate `<external>:<internal>` respectively. For example, `-p 8080:80` would expose port `80` from inside the container to be accessible from the host's IP on port `8080` outside the container.
For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional `-e UMASK=022` setting.
Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up [here](https://en.wikipedia.org/wiki/Umask) before asking for support.
When using volumes (`-v` flags), permissions issues can arise between the host OS and the container, we avoid this issue by allowing you to specify the user `PUID` and group `PGID`.

We publish various [Docker Mods](https://github.com/linuxserver/docker-mods) to enable additional functionality within the containers. The list of Mods available for this image (if any) as well as universal mods that can be applied to any one of our images can be accessed via the dynamic badges above.
docker inspect -f '{{ index .Config.Labels "build_version" }}' qbittorrent
```
* Image version number:
```bash
docker inspect -f '{{ index .Config.Labels "build_version" }}' lscr.io/linuxserver/qbittorrent:latest
```
## Updating Info
Most of our images are static, versioned, and require an image update and container recreation to update the app inside. With some exceptions (ie. nextcloud, plex), we do not recommend or support updating apps inside the container. Please consult the [Application Setup](#application-setup) section above to see if it is recommended for the image.
Below are the instructions for updating containers:
* Recreate a new container with the same docker run parameters as instructed above (if mapped correctly to a host folder, your `/config` folder and settings will be preserved)
* You can also remove the old dangling images:
```bash
docker image prune
```
### Via Watchtower auto-updater (only use if you don't remember the original parameters)
* Pull the latest image at its tag and replace it with the same env variables in one run:
```bash
docker run --rm \
-v /var/run/docker.sock:/var/run/docker.sock \
containrrr/watchtower \
--run-once qbittorrent
```
* You can also remove the old dangling images: `docker image prune`
!!! warning
We do not endorse the use of Watchtower as a solution to automated updates of existing Docker containers. In fact we generally discourage automated updates. However, this is a useful tool for one-time manual updates of containers where you have forgotten the original parameters. In the long term, we highly recommend using [Docker Compose](https://docs.linuxserver.io/general/docker-compose).
We recommend [Diun](https://crazymax.dev/diun/) for update notifications. Other tools that automatically update containers unattended are not recommended or supported.
## Building locally
