Application Setup
The Webtop can be accessed at:
http://yourhost:3000/
By default the user/pass is abc/abc, if you change your password or want to login manually to the GUI session for any reason use the following link:
http://yourhost:3000/?login=true
You can also force login on the '/' path without this parameter by passing the environment variable -e AUTO_LOGIN=false.
You can access advanced features of the Guacamole remote desktop using ctrl+alt+shift enabling you to use remote copy/paste, an onscreen keyboard, or a baked in file manager. This can also be accessed by clicking the small circle on the left side of the screen.
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
Unlike our other containers these Desktops are not designed to be upgraded by Docker, you will keep your home directoy 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
Keyboard Layouts
This should match the layout on the computer you are accessing the container from.
The keyboard layouts available for use are:
da-dk-qwerty- Danish keyboard
de-ch-qwertz- Swiss German keyboard (qwertz)
de-de-qwertz- German keyboard (qwertz) - OSK available
en-gb-qwerty- English (UK) keyboard
en-us-qwerty- English (US) keyboard - OSK available DEFAULT
es-es-qwerty- Spanish keyboard - OSK available
fr-ch-qwertz- Swiss French keyboard (qwertz)
fr-fr-azerty- French keyboard (azerty) - OSK available
it-it-qwerty- Italian keyboard - OSK available
ja-jp-qwerty- Japanese keyboard
pt-br-qwerty- Portuguese Brazilian keyboard
sv-se-qwerty- Swedish keyboard
tr-tr-qwerty- Turkish-Q keyboard
If you ever lose your password you can always reset it by execing into the container as root:
1
docker exec -it webtop passwd abc
Copied!
By default we perform all logic for the abc user and we reccomend 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 reccomend ever publishing their ports to the public Internet.
Hardware Acceleration (Ubuntu Container Only)
Many desktop application will need access to a GPU to function properly and even some Desktop Environments have compisitor effects that will not function without a GPU. This is not a hard requirement and all base images will function without a video device mounted into the container.
Intel/ATI/AMD
To leverage hardware acceleration you will need to mount /dev/dri video device inside of the conainer.
1
--device=/dev/dri:/dev/dri
Copied!
We will automatically ensure the abc user inside of the container has the proper permissions to access this device.
Nvidia
Hardware acceleration users for Nvidia will need to install the container runtime provided by Nvidia on their host, instructions can be found here: https://github.com/NVIDIA/nvidia-docker
We automatically add the necessary environment variable that will utilise all the features available on a GPU on the host. Once nvidia-docker is installed on your host you will need to re/create the docker container with the nvidia container runtime --runtime=nvidia and add an environment variable -e NVIDIA_VISIBLE_DEVICES=all (can also be set to a specific gpu's UUID, this can be discovered by running nvidia-smi --query-gpu=gpu_name,gpu_uuid --format=csv ). NVIDIA automatically mounts the GPU and drivers from your host into the container.
Arm Devices
Best effort is made to install tools to allow mounting in /dev/dri on Arm devices. In most cases if /dev/dri exists on the host it should just work. If running a Raspberry Pi 4 be sure to enable dtoverlay=vc4-fkms-v3d in your usercfg.txt.
Usage
To help you get started creating a container from this image you can either use docker-compose or the docker cli.

Parameters
Docker images 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)
Parameter
Function
3000
Web Desktop GUI
Environment Variables (-e)
Env
Function
PUID=1000
for UserID - see below for explanation
PGID=1000
for GroupID - see below for explanation
TZ=Europe/London
Specify a timezone to use EG Europe/London
SUBFOLDER=/
Specify a subfolder to use with reverse proxies, IE /subfolder/
KEYBOARD=en-us-qwerty
See the keyboard layouts section for more information and options.
Volume Mappings (-v)
Volume
Function
/config
abc users home directory
/var/run/docker.sock
Docker Socket on the system, if you want to use Docker in the container
Device Mappings (--device)
Parameter
Function
/dev/dri
Add this for GL support (Linux hosts only)
Miscellaneous Options
Parameter
Function
--shm-size=
We set this to 1 gig to prevent modern web browsers from crashing
--security-opt seccomp=unconfined
For Docker Engine only, many modern gui apps need this to function as syscalls are unkown to Docker.
Environment variables from files (Docker secrets)
You can set any environment variable from a file by using a special prepend FILE__.
As an example:
1
-e FILE__PASSWORD=/run/secrets/mysecretpassword
Copied!
Will set the environment variable PASSWORD based on the contents of the /run/secrets/mysecretpassword 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 user as below:
1
  $ id username
2
    uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)
Copied!
