webtop

linuxserver/webtop

Webtop - Alpine, Ubuntu, Fedora, and Arch based containers containing full desktop environments in officially supported flavors accessible via any modern web browser.

Supported Architectures

Our images support multiple architectures such as x86-64, arm64 and armhf. 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/webtop 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:

Architecture	Tag
x86-64	amd64-latest
arm64	arm64v8-latest
armhf	arm32v7-latest

Version Tags

This image provides various versions that are available via tags. latest tag usually provides the latest stable version. Others are considered under development and caution must be exercised when using them.

Tag	Description
latest	XFCE Alpine
ubuntu-xfce	XFCE Ubuntu
fedora-xfce	XFCE Fedora
arch-xfce	XFCE Arch
alpine-kde	KDE Alpine
ubuntu-kde	KDE Ubuntu
fedora-kde	KDE Fedora
arch-kde	KDE Arch
alpine-mate	MATE Alpine
ubuntu-mate	MATE Ubuntu
fedora-mate	MATE Fedora

alpine-i3	i3 Alpine
ubuntu-i3	i3 Ubuntu
fedora-i3	i3 Fedora
arch-i3	i3 Arch
alpine-openbox	Openbox Alpine
ubuntu-openbox	Openbox Ubuntu
fedora-openbox	Openbox Fedora
arch-openbox	Openbox Arch
alpine-icewm	IceWM Alpine

arch-icewm	IceWM Arch

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 access advanced features of the Guacamole remote desktop using ctrl+alt+shift enabling you to use remote copy/paste or an onscreen keyboard.

Modern GUI desktop apps (including some flavors terminals) have issues with the latest Docker and syscall compatibility, you can use Docker with the 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

The KDE Ubuntu container needs to be run in privileged mode to function properly, in general the Ubuntu KDE container while functional is not reccomended, please try a different KDE distro if possible

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

docker exec -it webtop passwd abc

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.

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)

version: "2.1"
services:
  webtop:
    image: lscr.io/linuxserver/webtop
    container_name: webtop
    privileged: true #optional
    security_opt:

docker cli (click here for more info)

docker run -d \

  --security-opt seccomp=unconfined `#optional` \
  -e PUID=1000 \
  -e PGID=1000 \

  --shm-size="1gb" `#optional` \
  --restart unless-stopped \
  lscr.io/linuxserver/webtop

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/`

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

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 (try this before privileged)

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

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
