⁠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

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: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 application can be accessed at:

• https://yourhost:3001/⁠

⁠Strict reverse proxies

This image uses a self-signed certificate by default. This naturally means the scheme is https. If you are using a reverse proxy which validates certificates, you need to disable this check for the container⁠.

This container is based on Docker Baseimage Selkies⁠, which streams a desktop or single application to your web browser. Only the essentials are covered below, the full platform documentation lives at docs.linuxserver.io/selkies⁠.

⁠Start Minimal

Most support issues we see stem from large run configurations assembled from years of forum posts. These containers are designed to work with almost nothing. Start with the minimal command below, confirm it works, then add your options (volumes, env vars, GPU flags) one at a time:

docker run --rm -it \
  --shm-size=1gb \
  -p 3001:3001 \
  lscr.io/linuxserver/webtop:latest bash

Open https://localhost:3001⁠ (note the https) and accept the self signed certificate warning. The trailing bash gives you a shell inside the container, ctrl+d exits and cleans everything up. If a bigger setup misbehaves, return to this command to isolate the problem, see the Quickstart⁠ and Troubleshooting⁠ guides.

⁠GPU Acceleration

A GPU is optional, the CPU pipeline is fast enough for smooth sessions on modest hardware. When a GPU is mounted into the container it is automatically detected and configured for zero copy rendering and encoding, set AUTO_GPU=false to disable this behavior.

Intel / AMD (open source drivers), one flag is all it takes:

docker run --rm -it \
  --shm-size=1gb \
  -p 3001:3001 \
  --device /dev/dri \
  lscr.io/linuxserver/webtop:latest bash

Nvidia (proprietary drivers, not available on Alpine based images):

Requires host driver 580 or newer installed from the .run file downloaded directly from Nvidia. On drivers older than 595.80 you may also need kernel parameters and a dummy plug, see GPU Acceleration⁠ before opening an issue.

docker run --rm -it \
  --shm-size=1gb \
  -p 3001:3001 \
  --runtime nvidia \
  --gpus all \
  --device /dev/nvidia-modeset \
  lscr.io/linuxserver/webtop:latest bash

Compose examples, multi GPU selection (DRINODE/DRI_NODE), Unraid notes, and a step by step debugging loop are in the GPU Acceleration⁠ guide.

⁠Security

HTTPS is required. Modern browser features used for video and audio (WebCodecs) only work in a secure context. Port 3001 serves HTTPS directly, the HTTP port exists only to sit behind a reverse proxy.

By default there is no authentication. Setting the CUSTOM_USER and PASSWORD environment variables enables HTTP basic auth, which is suitable only for a trusted local network. For internet exposure, place the container behind a reverse proxy with robust authentication, such as SWAG⁠. Keep in mind the web interface includes a terminal with passwordless sudo, anyone who can reach the GUI can gain root inside the container.

Authentication options, sharing link behavior, container isolation, and the lockdown variables for kiosk style deployments are covered in Security and Hardening⁠.

⁠Language Support - Internationalization

To launch the session in a different language, set the LC_ALL environment variable, e.g. -e LC_ALL=zh_CN.UTF-8 (Chinese), ja_JP.UTF-8 (Japanese), ko_KR.UTF-8 (Korean), ar_AE.UTF-8 (Arabic), ru_RU.UTF-8 (Russian), es_MX.UTF-8 (Spanish Latin America), de_DE.UTF-8 (German), fr_FR.UTF-8 (French), nl_NL.UTF-8 (Dutch), it_IT.UTF-8 (Italian).

⁠Beyond Running the App

This image inherits every capability of the Selkies platform, all documented in depth on the docs site:

• Configuration Reference⁠ - every environment variable: ports, subfolder reverse proxy, custom dashboards, watermarking, and the full set of SELKIES_* stream, feature, and UI settings with their |locked syntax.
• Using the Web Client⁠ - file transfer, clipboard sync, audio and microphone, up to four gamepads, session sharing, and mobile touch support.
• Installing Applications⁠ - persistent user installed apps with proot-apps⁠ (proot-apps install filezilla) or native packages at boot with Docker mods.
• Docker in Docker and host Docker control⁠ - run --privileged for an isolated DinD setup, or mount /var/run/docker.sock to manage the host.
• Reverse Proxy⁠ - proxying websockets and subfolders correctly.
• SealSkin⁠ - turnkey multi user VDI orchestration with browser extension and mobile apps, this image is fully compatible.
• Pelorus⁠ - expose the session to AI agents via a computer use API and accessibility stack.

⁠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:
  webtop:
    image: lscr.io/linuxserver/webtop:latest
    container_name: webtop
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Etc/UTC
    volumes:
      - /path/to/data:/config
    ports:
      - 3000:3000
      - 3001:3001
    shm_size: "1gb"
    restart: unless-stopped

⁠docker cli (click here for more info⁠)

docker run -d \
  --name=webtop \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Etc/UTC \
  -p 3000:3000 \
  -p 3001:3001 \
  -v /path/to/data:/config \
  --shm-size="1gb" \
  --restart unless-stopped \
  lscr.io/linuxserver/webtop: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.

⁠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
  

  Copy

• To monitor the logs of the container in realtime:

  docker logs -f webtop
  

  Copy

• Container version number:

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

  Copy

• Image version number:

  Copy

⁠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
    

    Copy

  • Single image:

    docker-compose pull webtop
    

    Copy

• Update containers:

  • All containers:

    docker-compose up -d
    

    Copy

  • Single container:

    docker-compose up -d webtop
    

    Copy

• You can also remove the old dangling images:

  docker image prune
  

  Copy

⁠Via Docker Run

• Update the image:

  docker pull lscr.io/linuxserver/webtop:latest
  

  Copy

• Stop the running container:

  docker stop webtop
  

  Copy

• Delete the container:

  docker rm webtop
  

  Copy

• 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
  

  Copy

⁠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 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.
