Reporting bugs

If the problem is related to Docker, please report it to this repository:
https://github.com/qbittorrent/docker-qbittorrent-nox/issues

https://github.com/qbittorrent/qBittorrent/issues

Usage

  1. Prerequisites

    In order to run this image you'll need Docker installed: https://docs.docker.com/get-docker/

    If you don't need the GUI, you can just install Docker Engine: https://docs.docker.com/engine/install/

    It is also recommended to install Docker Compose as it can significantly ease the process: https://docs.docker.com/compose/install/

  2. Download this repository

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

  3. Edit Docker environment file

    If you are using Docker Stack, refer to docker-stack.yml file as an example.
    It is an almost ready-to-use configuration yet a few variables are required 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 is crucial in 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 had read the legal notice of qBittorrent.
      Put confirm only if you had read the legal notice. You can find the legal notice here.
    • 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 here.
      You can put latest to use the latest stable release of qBittorrent.
      If you are up to test the bleeding-edge version, you can put alpha to get the weekly build.
    • QBT_WEBUI_PORT
      This environment variable sets the port number which qBittorrent WebUI will be binded to. 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 relative path won't work.
    • <your_path>/downloads
      Full path to a folder on your host machine which will store the files downloaded by qBittorrent. Using relative path won't work.

  4. Running the image

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

      export \
  QBT_LEGAL_NOTICE=<put_confirm_here> \
  QBT_VERSION=latest \
  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_WEBUI_PORT \
  -p "$QBT_WEBUI_PORT":"$QBT_WEBUI_PORT"/tcp \
  -p 6881:6881/tcp \
  -p 6881:6881/udp \
  -v "$QBT_CONFIG_PATH":/config \
  -v "$QBT_DOWNLOADS_PATH":/downloads \
  qbittorrentofficial/qbittorrent-nox:${QBT_VERSION}

    • If using Docker Compose:

      docker compose up

    • A few notes:

      • Alternatively, you can use ghcr.io/qbittorrent/docker-qbittorrent-nox:${QBT_VERSION} for the image path.
      • 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 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.
      • 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 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.
      • 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: 
        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'

  5. Stopping container

    • When using Docker (not Docker Compose):

      docker stop qbittorrent-nox

    • When using Docker Compose:

      docker compose down

Build image manually

Refer to manual_build folder.

Debugging

To attach gdb to the running qbittorent-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

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

  4. Install packages

    apk add \
  gdb \
  musl-dbg

  5. Attach gdb to the running process

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