  1. Kubernetes version 1.23 or newer
  2. GPU Support must be enabled
  3. Nebuly's device plugin (required only if using MPS partitioning)
  4. Cert Manager (optional, but recommended)

Enable GPU support

Before installing nos, you must enable GPU support in your Kubernetes cluster.

There are two ways to do this. One option is to manually install the required components individually,while the other consists in installing only the NVIDIA GPU Operator, which automatically installs all the necessary components for you. See below for more information on these two installation methods.

We recommended enabling GPU support using the NVIDIA GPU Operator (option 1).

Option 1 - NVIDIA GPU Operator

You can install the NVIDIA GPU Operator as follows:

helm install --wait --generate-name \
     -n gpu-operator --create-namespace \
     nvidia/gpu-operator --version v22.9.0 \
     --set driver.enabled=true \
     --set migManager.enabled=false \
     --set mig.strategy=mixed \
     --set toolkit.enabled=true

Note that the GPU Operator will automatically install a recent version of NVIDIA Drivers and CUDA on all the GPU-enabled nodes of your cluster, so you don't have to manually install them.

For further information you can refer to the NVIDIA GPU Operator Documentation.

Option 2 - Manual installation


If you want to enable MPS Dynamic Partitioning, make sure you have a version of CUDA 11.5 or newer installed, as this is the minimum version that supports GPU memory limits in MPS.

To enble GPU support in your cluster, you first need to install NVIDIA Drivers and the NVIDIA Container Toolkit on all the nodes of your cluster with a GPU.

After installing the NVIDIA Drivers and the Container Toolkit on your nodes, you need to install the following Kubernetes components:

Please note that the configuration parameter migStrategy must be set to mixed (you can do that with --set migStrategy=mixed if you are using Helm).

Install Nebuly's device plugin


Nebuly's device plugin is required only if you want to use dynamic MPS partitioning. If you don't plan to use MPS partitioning, you can then skip this installation step.

You can install Nebuly's device plugin using Helm as follows:

helm install oci:// \
  --version 0.13.0 \
  --generate-name \
  -n nebuly-nvidia \

Nebuly's device plugin runs only on nodes labelled with

If you already have the NVIDIA device plugin installed on your cluster, you need to ensure that only one instance of the device plugin is running on each GPU node (either Nebuly's or NVIDIA's). One way to do that is to add an affinity rule to the NVIDIA device plugin Daemonset so that it doesn't run on any node that has MPS enabled:

        - matchExpressions:
            - key:
              operator: NotIn
                - mps

For further information you can refer to Nebuly's device plugin documentation.
