linuxserver/rdesktop¶

Rdesktop - Containers containing full desktop environments in many popular flavors for Alpine, Ubuntu, Arch, and Fedora accessible via RDP.

Supported Architectures¶

We utilise the docker manifest for multi-platform awareness. More information is available from docker here and our announcement here.

Simply pulling lscr.io/linuxserver/rdesktop:latest should retrieve the correct image for your arch, but you can also pull specific arch images via tags.

The architectures supported by this image are:

Version 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.

Application Setup¶

The Default USERNAME and PASSWORD is: abc/abc

Unlike our other containers these Desktops are not designed to be upgraded by Docker, you will keep your home directory but anything you installed system level will be lost if you upgrade an existing container. To keep packages up to date instead use Ubuntu's own apt, Alpine's apk, Fedora's dnf, or Arch's pacman program

You will need a Remote Desktop client to access this container Wikipedia List, by default it listens on 3389, but you can change that port to whatever you wish on the host side IE 3390:3389. The first thing you should do when you login to the container is to change the abc users password by issuing the passwd command.

Modern GUI desktop apps (including some flavors terminals) have issues with the latest Docker and syscall compatibility, you can use Docker with the --security-opt seccomp=unconfined setting to allow these syscalls or try podman as they have updated their codebase to support them

If you ever lose your password you can always reset it by execing into the container as root:

docker exec -it rdesktop passwd abc

By default we perform all logic for the abc user and we recommend using that user only in the container, but new users can be added as long as there is a startwm.sh executable script in their home directory. All of these containers are configured with passwordless sudo, we make no efforts to secure or harden these containers and we do not recommend ever publishing their ports to the public Internet.

Options¶

All application settings are passed via environment variables:

Language Support - Internationalization¶

The environment variable LC_ALL can be used to start this image in a different language than English simply pass for example to launch the Desktop session in French LC_ALL=fr_FR.UTF-8. Some languages like Chinese, Japanese, or Korean will be missing fonts needed to render properly known as cjk fonts, but others may exist and not be installed. We only ensure fonts for Latin characters are present. Fonts can be installed with a mod on startup.

To install cjk fonts on startup as an example pass the environment variables(Debian):

-e DOCKER_MODS=linuxserver/mods:universal-package-install
-e INSTALL_PACKAGES=fonts-noto-cjk
-e LC_ALL=zh_CN.UTF-8

PRoot Apps¶

All images include proot-apps which allow portable applications to be installed to persistent storage in the user's $HOME directory. These applications and their settings will persist upgrades of the base container and can be mounted into different flavors of rdesktop containers. IE if you are running an Alpine based container you will be able to use the same /config directory mounted into an Ubuntu based container and retain the same applications and settings as long as they were installed with proot-apps install.

A list of linuxserver.io supported applications is located HERE.

Open Source GPU Acceleration¶

For accelerated apps or games, render devices can be mounted into the container and leveraged by applications using:

--device /dev/dri:/dev/dri

This feature only supports Open Source GPU drivers:

Nvidia GPU Support¶

Nvidia is not compatible with Alpine based images

Nvidia support is available by leveraging Zink for OpenGL support. This can be enabled with the following run flags:

The compose syntax is slightly different for this as you will need to set nvidia as the default runtime:

sudo nvidia-ctk runtime configure --runtime=docker --set-as-default
sudo service docker restart

And to assign the GPU in compose:

services:
  myimage:
    image: myname/myimage:mytag
    deploy:
      resources:
        reservations:
          devices:
            - driver: nvidia
              count: 1
              capabilities: [compute,video,graphics,utility]

Usage¶

To help you get started creating a container from this image you can either use docker-compose or the docker cli.

docker-compose (recommended, click here for more info)¶

---
services:
  rdesktop:
    image: lscr.io/linuxserver/rdesktop:latest
    container_name: rdesktop
    security_opt:
      - seccomp:unconfined #optional
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Etc/UTC
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock #optional
      - /path/to/rdesktop/data:/config #optional
    ports:
      - 3389:3389
    devices:
      - /dev/dri:/dev/dri #optional
    shm_size: "1gb" #optional
    restart: unless-stopped

docker cli (click here for more info)¶

docker run -d \
  --name=rdesktop \
  --security-opt seccomp=unconfined `#optional` \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Etc/UTC \
  -p 3389:3389 \
  -v /var/run/docker.sock:/var/run/docker.sock `#optional` \
  -v /path/to/rdesktop/data:/config `#optional` \
  --device /dev/dri:/dev/dri `#optional` \
  --shm-size="1gb" `#optional` \
  --restart unless-stopped \
  lscr.io/linuxserver/rdesktop:latest

Parameters¶

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.

Ports (-p)¶

Environment Variables (-e)¶

Volume Mappings (-v)¶

Device Mappings (--device)¶

Miscellaneous Options¶

Environment variables from files (Docker secrets)¶

You can set any environment variable from a file by using a special prepend FILE__.

As an example:

-e FILE__MYVAR=/run/secrets/mysecretvariable

Will set the environment variable MYVAR based on the contents of the /run/secrets/mysecretvariable file.

Umask for running applications¶

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 before asking for support.

User / Group Identifiers¶

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.

Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.

In this instance PUID=1000 and PGID=1000, to find yours use id your_user as below:

id your_user

Example output:

uid=1000(your_user) gid=1000(your_user) groups=1000(your_user)

Docker Mods¶

We publish various 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.

Support Info¶

• Shell access whilst the container is running:

  docker exec -it rdesktop /bin/bash
  

• To monitor the logs of the container in realtime:

  docker logs -f rdesktop
  

• Container version number:

  docker inspect -f '{{ index .Config.Labels "build_version" }}' rdesktop
  

• Image version number:

  docker inspect -f '{{ index .Config.Labels "build_version" }}' lscr.io/linuxserver/rdesktop: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 (noted in the relevant readme.md), we do not recommend or support updating apps inside the container. Please consult the Application Setup section above to see if it is recommended for the image.

Below are the instructions for updating containers:

Via Docker Compose¶

• Update images:

  • All images:

    docker-compose pull
    

  • Single image:

    docker-compose pull rdesktop
    

• Update containers:

  • All containers:

    docker-compose up -d
    

  • Single container:

    docker-compose up -d rdesktop
    

• You can also remove the old dangling images:

  docker image prune
  

Via Docker Run¶

• Update the image:

  docker pull lscr.io/linuxserver/rdesktop:latest
  

• Stop the running container:

  docker stop rdesktop
  

• Delete the container:

  docker rm rdesktop
  

• 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:

  docker image prune
  

Image Update Notifications - Diun (Docker Image Update Notifier)¶

Building locally¶

If you want to make local modifications to these images for development purposes or just to customize the logic:

git clone https://github.com/linuxserver/docker-rdesktop.git
cd docker-rdesktop
docker build \
  --no-cache \
  --pull \
  -t lscr.io/linuxserver/rdesktop:latest .

The ARM variants can be built on x86_64 hardware and vice versa using lscr.io/linuxserver/qemu-static

docker run --rm --privileged lscr.io/linuxserver/qemu-static --reset

Once registered you can define the dockerfile to use with -f Dockerfile.aarch64.
