Appearance

Using node-llama-cpp in Docker ​

When using node-llama-cpp in a docker image to run it with Docker or Podman, you will most likely want to use it together with a GPU for fast inference.

For that, you'll have to:

  1. Configure support for your GPU on the host machine
  2. Build an image with the necessary GPU libraries
  3. Enable GPU support when running the container

Configuring the Host Machine ​

Metal: Using Metal in of a docker container is not supported.

CUDA: You need to install the NVIDIA Container Toolkit on the host machine to use NVIDIA GPUs.

Vulkan: You need to install the relevant GPU drives on the host machine, and configure Docker or Podman to use them.

No GPU (CPU only): No special configuration is needed.

Building an Image ​

WARNING

Do not attempt to use alpine as the base image as it doesn't work well with many GPU drivers.

The potential image size savings of using alpine images are not worth the hassle, especially considering that the models files you use will likely be much larger than the image itself anyway.

Running the Container ​

To run the container with GPU support, use the following:

shell
docker run --rm -it --gpus=all my-image:tag
shell
podman run --rm -it --gpus=all my-image:tag
yaml
services:
  my-service:
    image: my-image:tag
    deploy:
      resources:
        reservations:
          devices:
            - capabilities: [gpu]
              count: all

When using the CLI, you can test the GPU support by running this command

shell
docker run --rm -it --gpus=all my-image:tag npx -y node-llama-cpp inspect gpu
shell
podman run --rm -it --gpus=all my-image:tag npx -y node-llama-cpp inspect gpu

Troubleshooting ​

NVIDIA GPU Is Not Recognized by the Vulkan Driver Inside the Container ​

Make sure your Docker/Podman configuration has an nvidia runtime:

json
{
    "runtimes": {
        "nvidia": {
            "args": [],
            "path": "nvidia-container-runtime"
        }
    }
}
shell
sudo nvidia-ctk cdi generate --output=/etc/cdi/nvidia.yaml
nvidia-ctk cdi list

And then run the container with the nvidia runtime:

shell
docker run --rm -it --runtime=nvidia --gpus=all my-image:tag
shell
podman run --rm -it --device nvidia.com/gpu=all --security-opt=label=disable --gpus=all my-image:tag

Getting an system has unsupported display driver / cuda driver combination Error ​

Ensure that the INSTALL_CUDA_VERSION in the Dockerfile matches or is older than the CUDA version installed on the host machine.

You can check what is the installed CUDA version using nvidia-smi --version.
