Prequisities

Prerequisites​

Preparing your GPU Nodes​

Execute the following steps on all your GPU nodes.

This README assumes pre-installation of NVIDIA drivers and the nvidia-container-toolkit. Additionally, it assumes configuration of the nvidia-container-runtime as the default low-level runtime.

Please see: https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/install-guide.html

Example for debian-based systems with Docker and containerd​

Install the nvidia-container-toolkit​

distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
curl -s -L https://nvidia.github.io/libnvidia-container/gpgkey | sudo apt-key add -
curl -s -L https://nvidia.github.io/libnvidia-container/$distribution/libnvidia-container.list | sudo tee /etc/apt/sources.list.d/libnvidia-container.list

sudo apt-get update && sudo apt-get install -y nvidia-container-toolkit

Configure Docker​

When running Kubernetes with Docker, edit the configuration file, typically located at /etc/docker/daemon.json, to set up nvidia-container-runtime as the default low-level runtime:

{
    "default-runtime": "nvidia",
    "runtimes": {
        "nvidia": {
            "path": "/usr/bin/nvidia-container-runtime",
            "runtimeArgs": []
        }
    }
}

And then restart Docker:

sudo systemctl daemon-reload && systemctl restart docker

Configure containerd​

When running Kubernetes with containerd, modify the configuration file typically located at /etc/containerd/config.toml, to set up nvidia-container-runtime as the default low-level runtime:

version = 2
[plugins]
  [plugins."io.containerd.grpc.v1.cri"]
    [plugins."io.containerd.grpc.v1.cri".containerd]
      default_runtime_name = "nvidia"

      [plugins."io.containerd.grpc.v1.cri".containerd.runtimes]
        [plugins."io.containerd.grpc.v1.cri".containerd.runtimes.nvidia]
          privileged_without_host_devices = false
          runtime_engine = ""
          runtime_root = ""
          runtime_type = "io.containerd.runc.v2"
          [plugins."io.containerd.grpc.v1.cri".containerd.runtimes.nvidia.options]
            BinaryName = "/usr/bin/nvidia-container-runtime"

And then restart containerd:

sudo systemctl daemon-reload && systemctl restart containerd

Label your nodes​

Label your GPU nodes for scheduling with HAMi by adding the label "gpu=on". Without this label, the nodes cannot be managed by our scheduler.

kubectl label nodes {nodeid} gpu=on
