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

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/Debians's own apt, Alpine's apk, Fedora's dnf, or Arch's pacman program

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

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 appplications. Only Open Source drivers are supported IE (Intel,AMDGPU,Radeon,ATI,Nouveau)

Language Support - Internationalization

The universal internationalization docker mod can be used with any of these variants to provide non english language support. All you need to know is your specific iso-639 code for your your desired language. For example German is de_DE.UTF-8 Chinese zh_CN.UTF-8 a full list is here:

https://github.com/linuxserver/docker-mods/tree/universal-internationalization#other-languages

To enable this pass the environment variables:

-e DOCKER_MODS=linuxserver/mods:universal-internationalization
-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 in conjunction with the mod it will perform the same as a local Linux installation set to your locale.

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.

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

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
3001	Web Desktop GUI HTTPS

Environment Variables (-e)

Env	Function
PUID=1000	for UserID - see below for explanation
PGID=1000	for GroupID - see below for explanation
TZ=Etc/UTC	specify a timezone to use, see this list.
SUBFOLDER=/	Specify a subfolder to use with reverse proxies, IE /subfolder/
TITLE=Webtop	String which will be used as page/tab title in the web browser.

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 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__PASSWORD=/run/secrets/mysecretpassword

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:

  $ id username
    uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)

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
