Containerizing your the Simulation builds

Assuming you have followed our build for LHS instructions here, and have the binary (or the executable) ready, lets dive into how we can containerize it to run at scale.

Working with Docker

There are three prerequisites to running a Linux Headless Simulation(LHS) in a Docker container.

  • Host machine must have Nvidia graphics drivers installed
  • Host machine must have the Nvidia Container Toolkit installed
  • The Docker container must have the Vulkan library installed.

Setting up Vulkan in a Docker Container

It is recommended to use an official Vulkan tagged Docker image from Nvidia as a base image: https://hub.docker.com/r/nvidia/vulkan/tags.

If it isn't possible to change your base image to a Vulkan image you can copy the Vulkan libraries from the official image.

Warning: When copying the Vulkan libraries from an official image make sure the OS used in the official image matches the OS on your host machine.

# Your DockerFile Here

# Setup Vulkan
COPY --from=nvidia/vulkan:1.1.121-cuda-10.1-beta.1-ubuntu18.04 /usr/local/include/vulkan /usr/local/include/vulkan
COPY --from=nvidia/vulkan:1.1.121-cuda-10.1-beta.1-ubuntu18.04 /usr/local/share/vulkan /usr/local/share/vulkan
COPY --from=nvidia/vulkan:1.1.121-cuda-10.1-beta.1-ubuntu18.04 /etc/vulkan/icd.d/nvidia_icd.json /etc/vulkan/icd.d/nvidia_icd.json
COPY --from=nvidia/vulkan:1.1.121-cuda-10.1-beta.1-ubuntu18.04 /usr/local/lib/lib* /usr/local/lib/

Running the Docker Container

When running the Vulkan enabled Docker Container the --gpus flag must be used with docker run to give access to the host GPU to the container.

docker run --gpus all <docker-image> <command>
