Blender is a free and open-source 3D computer graphics software toolset used for creating animated films, visual effects, art, 3D printed models, motion graphics, interactive 3D applications, virtual reality, and computer games. This image does not support GPU rendering out of the box only accelerated workspace experience

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/blender: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:

The application can be accessed at:

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

This only applies to your desktop experience, this container is capable of supporting accelerated rendering with /dev/dri mounted in, but the AMD HIP and Nvidia CUDA runtimes are massive which are not installed by default in this container.

To leverage hardware acceleration you will need to mount /dev/dri video device inside of the conainer.

--device /dev/dri:/dev/dri

We will automatically ensure the abc user inside of the container has the proper permissions to access this device.

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 can run this image, but generally should not mount in /dev/dri. The OpenGL ES version is not high enough to run Blender. The program can run on these platforms though, leveraging CPU LLVMPipe rendering.

Due to lack of arm64 binaries from the upstream project, our arm64 image installs the latest version from the ubuntu repo, which is usually behind and thus the version the image is tagged with does not match the version contained.

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

The environment variable LC_ALL can be used to start this image 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. 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:

-e DOCKER_MODS=linuxserver/mods:universal-package-install
-e INSTALL_PACKAGES=fonts-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.

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.

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

---
services:
  blender:
    image: lscr.io/linuxserver/blender:latest
    container_name: blender
    security_opt:
      - seccomp:unconfined #optional
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Etc/UTC
      - SUBFOLDER=/ #optional
    volumes:
      - /path/to/config:/config
    ports:
      - 3000:3000
      - 3001:3001
    restart: unless-stopped

docker run -d \
  --name=blender \
  --security-opt seccomp=unconfined `#optional` \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Etc/UTC \
  -e SUBFOLDER=/ `#optional` \
  -p 3000:3000 \
  -p 3001:3001 \
  -v /path/to/config:/config \
  --restart unless-stopped \
  lscr.io/linuxserver/blender:latest

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.

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.

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.

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)

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.

• Shell access whilst the container is running:

  docker exec -it blender /bin/bash

• To monitor the logs of the container in realtime:

  docker logs -f blender

• Container version number:

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

• Image version number:

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

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:

• Update images:

  • All images:

    docker-compose pull

  • Single image:

    docker-compose pull blender

• Update containers:

  • All containers:

    docker-compose up -d

  • Single container:

    docker-compose up -d blender

• You can also remove the old dangling images:

  docker image prune

• Update the image:

  docker pull lscr.io/linuxserver/blender:latest

• Stop the running container:

  docker stop blender

• Delete the container:

  docker rm blender

• 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

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

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

• 10.02.24: - Update Readme with new env vars and ingest proper PWA icon.
• 18.03.23: - Rebase to KasmVNC base image.
• 13.12.22: - Rebase to Jammy, migrate to s6v3.
• 06.05.22: - Use the full semver version in image tags. Arm32/64 version tags are inaccurate due to installing from ubuntu repo, which is usually behind.
• 12.03.22: - Initial Release.
