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

Supported Architectures

We utilise the docker manifest for multi-platform awareness. More information is available from docker here and our announcement here.
Simply pulling 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:
amd64-<version tag>
arm64v8-<version tag>

Application Setup

The application can be accessed at:
  • http://yourhost:3000/
  • https://yourhost:3001/

Hardware Acceleration

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:
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

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.

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

Internal port the container listens on for http if it needs to be swapped from the default 3000.
Internal port the container listens on for https if it needs to be swapped from the default 3001.
HTTP Basic auth username, abc is default.
HTTP Basic auth password, abc is default. If unset there will be no auth
Subfolder for the application if running a subfolder reverse proxy, need both slashes IE /subfolder/
The page title displayed on the web browser, default "KasmVNC Client".
This is the home directory (landing) for the file manager, default "/config".
If set to false a container with privilege will not automatically start the DinD Docker setup.
If mounting in /dev/dri for DRI3 GPU Acceleration allows you to specify the device to use IE /dev/dri/renderD128

Optional run configurations

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)

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.


To help you get started creating a container from this image you can either use docker-compose or the docker cli.
version: "2.1"
container_name: blender
- seccomp:unconfined #optional
- PUID=1000
- PGID=1000
- TZ=Etc/UTC
- SUBFOLDER=/ #optional
- /path/to/config:/config
- 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 \


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)

Blender desktop gui
Blender desktop gui HTTPS

Environment Variables (-e)

for UserID - see below for explanation
for GroupID - see below for explanation
specify a timezone to use, see this list.
Specify a subfolder to use with reverse proxies, IE /subfolder/

Volume Mappings (-v)

Users home directory in the container, stores local files and settings

Miscellaneous Options

--security-opt seccomp=unconfined
For Docker Engine only, this may be required depending on your Docker and storage configuration.

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 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" }}'


  • 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.
