Application Setup

The Webtop can be accessed at:

• http://yourhost:3000/
• https://yourhost:3001/

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

Application management

PRoot Apps

If you run system native installations of software IE sudo apt-get install filezilla and then upgrade or destroy/re-create the container that software will be removed and the Webtop will be at a clean state. For some users that will be acceptable and they can update their system packages as well using system native commands like apt-get upgrade. If you want Docker to handle upgrading the container and retain your applications and settings we have created proot-apps which allow portable applications to be installed to persistent storage in the user's $HOME directory and they will work in a confined Docker environment out of the box. These applications and their settings will persist upgrades of the base container and can be mounted into different flavors of Webtop containers on the fly facilitating virtual "Distro Hopping". IE if you are running the alpine-mate Webtop you will be able to use the same /config directory mounted into the arch-kde Webtop and retain the same applications and settings as long as they were installed with proot-apps install. This can be achieved from the command line with:

proot-apps install filezilla

PRoot Apps is included in all KasmVNC based containers, a list of linuxserver.io supported applications is located HERE.

Native Apps

It is possible to install extra packages during container start using universal-package-install. It might increase starting time significantly. PRoot is preferred.

  environment:
    - DOCKER_MODS=linuxserver/mods:universal-package-install
    - INSTALL_PACKAGES=libfuse2|git|gdb

Options in all KasmVNC based GUI containers

This container is based on Docker Baseimage KasmVNC which means there are additional environment variables and run configurations to enable or disable specific functionality.

Optional environment variables

Variable	Description
CUSTOM_PORT	Internal port the container listens on for http if it needs to be swapped from the default 3000.
CUSTOM_HTTPS_PORT	Internal port the container listens on for https if it needs to be swapped from the default 3001.
CUSTOM_USER	HTTP Basic auth username, abc is default.
PASSWORD	HTTP Basic auth password, abc is default. If unset there will be no auth
SUBFOLDER	Subfolder for the application if running a subfolder reverse proxy, need both slashes IE /subfolder/
TITLE	The page title displayed on the web browser, default "KasmVNC Client".
FM_HOME	This is the home directory (landing) for the file manager, default "/config".
START_DOCKER	If set to false a container with privilege will not automatically start the DinD Docker setup.
DRINODE	If mounting in /dev/dri for DRI3 GPU Acceleration allows you to specify the device to use IE /dev/dri/renderD128
DISABLE_IPV6	If set to true or any value this will disable IPv6
LC_ALL	Set the Language for the container to run as IE fr_FR.UTF-8 ar_AE.UTF-8
NO_DECOR	If set the application will run without window borders in openbox for use as a PWA.
NO_FULL	Do not autmatically fullscreen applications when using openbox.

Optional run configurations

Variable	Description
--privileged	Will start a Docker in Docker (DinD) setup inside the container to use docker in an isolated environment. For increased performance mount the Docker directory inside the container to the host IE -v /home/user/docker-data:/var/lib/docker.
-v /var/run/docker.sock:/var/run/docker.sock	Mount in the host level Docker socket to either interact with it via CLI or use Docker enabled applications.
--device /dev/dri:/dev/dri	Mount a GPU into the container, this can be used in conjunction with the DRINODE environment variable to leverage a host video card for GPU accelerated applications. Only Open Source drivers are supported IE (Intel,AMDGPU,Radeon,ATI,Nouveau)

Language Support - Internationalization

The environment variable LC_ALL can be used to start Webtop 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 inside the Webtop depending on what underlying distribution you are running. 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 (Alpine base):

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

The web interface has the option for "IME Input Mode" in Settings which will allow non english characters to be used from a non en_US keyboard on the client. Once enabled it will perform the same as a local Linux installation set to your locale.

DRI3 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:

Driver	Description
Intel	i965 and i915 drivers for Intel iGPU chipsets
AMD	AMDGPU, Radeon, and ATI drivers for AMD dedicated or APU chipsets
NVIDIA	nouveau2 drivers only, closed source NVIDIA drivers lack DRI3 support

The DRINODE environment variable can be used to point to a specific GPU. Up to date information can be found here

Display Compositing (desktop effects)

When using this image in tandem with a supported video card, compositing will function albeit with a performance hit when syncing the frames with pixmaps for the applications using it. This can greatly increase app compatibility if the application in question requires compositing, but requires a real GPU to be mounted into the container. By default we disable compositing at a DE level for performance reasons on our downstream images, but it can be enabled by the user and programs using compositing will still function even if the DE has it disabled in its settings. When building desktop images be sure you understand that with it enabled by default only users that have a compatible GPU mounted in will be able to use your image.

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:

Variable	Description
--gpus all	This can be filtered down but for most setups this will pass the one Nvidia GPU on the system
--runtime nvidia	Specify the Nvidia runtime which mounts drivers and tools in from the host

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:
  webtop:
    image: linuxserver/webtop:debian-kde
    deploy:
      resources:
        reservations:
          devices:
            - driver: nvidia
              count: 1
              capabilities: [compute,video,graphics,utility]

Lossless mode

This container is capable of delivering a true lossless image at a high framerate to your web browser by changing the Stream Quality preset to "Lossless", more information here. In order to use this mode from a non localhost endpoint the HTTPS port on 3001 needs to be used. If using a reverse proxy to port 3000 specific headers will need to be set as outlined here.

Usage

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

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.

Parameter	Function
-p 3000	Web Desktop GUI
-p 3001	Web Desktop GUI HTTPS
-e PUID=1000	for UserID - see below for explanation
-e PGID=1000	for GroupID - see below for explanation
-e TZ=Etc/UTC	specify a timezone to use, see this list.
-e SUBFOLDER=/	Specify a subfolder to use with reverse proxies, IE /subfolder/
-e TITLE=Webtop	String which will be used as page/tab title in the web browser.
-v /config	abc users home directory
-v /var/run/docker.sock	Docker Socket on the system, if you want to use Docker in the container
--device /dev/dri	Add this for GL support (Linux hosts only)
--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 on older hosts as syscalls are unknown 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:

-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 webtop /bin/bash

• To monitor the logs of the container in realtime:

  docker logs -f webtop

• Container version number:

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

• Image version number:

  docker inspect -f '{{ index .Config.Labels "build_version" }}' lscr.io/linuxserver/webtop: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 webtop

• Update containers:

  • All containers:

    docker-compose up -d

  • Single container:

    docker-compose up -d webtop

• You can also remove the old dangling images:

  docker image prune

Via Docker Run

• Update the image:

  docker pull lscr.io/linuxserver/webtop:latest

• Stop the running container:

  docker stop webtop

• Delete the container:

  docker rm webtop

• 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)

Tip

We recommend Diun for update notifications. Other tools that automatically update containers unattended are not recommended or supported.

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-webtop.git
cd docker-webtop
docker build \
  --no-cache \
  --pull \
  -t lscr.io/linuxserver/webtop:latest .

The ARM variants can be built on x86_64 hardware using multiarch/qemu-user-static

docker run --rm --privileged multiarch/qemu-user-static:register --reset

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