nos is the open-source module to efficiently run AI workloads on Kubernetes, increasing GPU utilization, cutting down infrastructure costs and improving workloads performance.

Currently, the available features are:

• Dynamic GPU partitioning: allow to schedule Pods requesting fractions of GPU. GPU partitioning is performed automatically in real-time based on the Pods pending and running in the cluster, so that Pods can request only the resources that are strictly necessary and GPUs are always fully utilized.

• Elastic Resource Quota management: increase the number of Pods running on the cluster by allowing namespaces to borrow quotas of reserved resources from other namespaces as long as they are not using them.

Getting started

Prerequisites

• Kubernetes v1.23 or newer
• GPU Support must be enabled
• Nebuly k8s-device-plugin (optional, required only if you want to enable MPS partitioning)
• cert-manager (optional, but recommended)

Installation

You can install nos using Helm 3 (recommended). You can find all the available configuration values in the Chart documentation.

helm install oci://ghcr.io/nebuly-ai/helm-charts/nos \
  --version 0.1.2 \
  --namespace nebuly-nos \
  --generate-name \
  --create-namespace

Alternatively, you can use Kustomize by cloning the repository and running make deploy.
