Usage

0. Prerequisites

   In order to run this image you will need Docker installed: [***]

   If you don't need the GUI, you can just install Docker Engine: [***]

   It is also recommended to install Docker Compose as it can simplify the process significantly: [***]

1. Download this repository

   You can either git clone this repository or download a .zip of it: https://github.com/qbittorrent/docker-qbittorrent-nox/archive/refs/heads/main.zip

2. Edit Docker environment file

   If you are using Docker Stack, refer to https://github.com/qbittorrent/docker-qbittorrent-nox/blob/main/docker-stack.yml file as an example.
   It is an almost ready-to-use configuration, though a few variables need to be filled in. Make sure you read the following steps as they largely share the same concept.

   If you are not using Docker Compose you can skip editing the environment file. However, the variables presented below are crucial for later steps, make sure you understand them.

   Find and open the .env file in the repository you cloned (or the .zip archive you downloaded).
   There are a few variables that you must take care of before you can run the image.
   You can find the meanings of these variables in the following section. Make sure you understand every one of them.

   Environment variables

   • QBT_LEGAL_NOTICE
     This environment variable defines whether you have read the legal notice of qBittorrent.
     Put confirm only if you have read the legal notice. You can find the legal notice https://github.com/qbittorrent/qBittorrent/blob/56667e717b82c79433ecb8a5ff6cc2d7b315d773/src/app/main.cpp#L320-L323.
   • QBT_VERSION
     This environment variable specifies the version of qBittorrent-nox to use.
     For example, 4.4.5-1 is a valid entry. You can find all tagged versions https://hub.docker.com/r/qbittorrentofficial/qbittorrent-nox/tags.
     You can put latest to use the latest stable release of qBittorrent.
     If you are looking to test the bleeding-edge version, you can put alpha to get the weekly build.
     A lt2 variation is available which uses libtorrent v2.0.x. However, users have reported memory/performance https://github.com/arvidn/libtorrent/issues/6667. Use at your own risk!
   • QBT_TORRENTING_PORT
     This environment variable defines the port number used for torrenting traffic. Defaults to port 6881 if value is not set.
   • QBT_WEBUI_PORT
     This environment variable defines the port number used for qBittorrent WebUI. Defaults to port 8080 if value is not set.

   Volumes

   There are some paths involved:

   • <your_path>/config
     Full path to a folder on your host machine which will store qBittorrent configurations. Using a relative path will not work.
   • <your_path>/downloads
     Full path to a folder on your host machine which will store the files downloaded by qBittorrent. Using a relative path will not work.

3. Running the image

   • If using Docker (not Docker Compose), edit the variables and run:

     shell
     export \
       QBT_LEGAL_NOTICE=<put_confirm_here> \
       QBT_VERSION=latest \
       QBT_TORRENTING_PORT=6881 \
       QBT_WEBUI_PORT=8080 \
       QBT_CONFIG_PATH="<your_path>/config" \
       QBT_DOWNLOADS_PATH="<your_path>/downloads"
     docker run \
       -t \
       --name qbittorrent-nox \
       --read-only \
       --rm \
       --stop-timeout 1800 \
       --tmpfs /tmp \
       -e QBT_LEGAL_NOTICE \
       -e QBT_TORRENTING_PORT \
       -e QBT_WEBUI_PORT \
       -p "$QBT_TORRENTING_PORT":"$QBT_TORRENTING_PORT"/tcp \
       -p "$QBT_TORRENTING_PORT":"$QBT_TORRENTING_PORT"/udp \
       -p "$QBT_WEBUI_PORT":"$QBT_WEBUI_PORT"/tcp \
       -v "$QBT_CONFIG_PATH":/config \
       -v "$QBT_DOWNLOADS_PATH":/downloads \
       qbittorrentofficial/qbittorrent-nox:${QBT_VERSION}
     

   • If using Docker Compose:

     shell
     docker compose up
     

   • A few notes:

     • Alternatively, you can use ghcr.io/qbittorrent/docker-qbittorrent-nox:${QBT_VERSION} for the image path.
     • You can pass command-line arguments to qbittorrent-nox by appending them to the end of docker run ... command. If using Docker Compose, modify the command: array in docker-compose.yml.
     • By default the timezone in the container uses the default of Alpine Linux (which is most likely UTC). You can set the environment variable TZ to your preferred value.
     • You can change the User ID (UID) and Group ID (GID) of the qbittorrent-nox process by setting environment variables PUID and PGID respectively. By default they are both set to 1000.
       Note that:
       1. You will need to remove --read-only flag (when using Docker) or set read_only: false (when using Docker Compose) as these settings are incompatible with each other.
       2. This setting has no effect when running the image in rootless mode.
     • You can set additional group ID (AGID) of the qbittorrent-nox process by setting the environment variable PAGID. For example: 10000,10001, this will set the process to be in two (secondary) groups 10000 and 10001. By default there is no additional group.
       Note that:
       1. You will need to remove --read-only flag (when using Docker) or set read_only: false (when using Docker Compose) as they are incompatible with it.
       2. This setting has no effect when running the image in rootless mode.
     • It is possible to set the umask of the qbittorrent-nox process by setting the environment variable UMASK. By default it uses the default from Alpine Linux.
     • You can list the compile-time Software Bill of Materials (sbom) with the following command:

       shell
       docker run --entrypoint /bin/cat --rm qbittorrentofficial/qbittorrent-nox:latest /sbom.txt
       

   • Then you can login to qBittorrent-nox at: http://<your_docker_host_address>:8080

     • For older qBittorrent versions (< 4.6.1), the default username/password is: admin/adminadmin.
     • For newer qBittorrent versions (≥ 4.6.1), qBittorrent will generate a temporary password and print it to the console (via stdout). You need to use it to login. See the announcement.
       If you don't have a console attached, you can run docker logs qbittorrent-nox to show the logs.

     After logging in, don't forget to change the password to something else!
     To change it in WebUI: 'Tools' menu -> 'Options...' -> 'Web UI' tab -> 'Authentication'

4. Stopping container

   • When using Docker (not Docker Compose):

     shell
     docker stop qbittorrent-nox
     

   • When using Docker Compose:

     shell
     docker compose down
     

Build image manually

Refer to https://github.com/qbittorrent/docker-qbittorrent-nox/tree/main/manual_build folder.

Debugging

To attach gdb to the running qbittorrent-nox process, follow the steps below:

1. Before you start the container

   • Remove --read-only as it will need additional packages within the container.
     Or disable the respective attributes in docker-compose.yml.
   • Add --cap-add=SYS_PTRACE to docker run argument list.
     Or enable the respective attributes in docker-compose.yml.

2. Start the container

3. Drop into container

   shell
   # to find container id
   docker ps
   # drop into container
   docker exec -it <container_id> /bin/sh
   

4. Install packages

   shell
   apk add \
     gdb \
     musl-dbg
   

5. Attach gdb to the running process

   shell
   # to find PID of qbittorrent-nox
   ps -a
   # attach debugger
   gdb -p <PID>
