Install NeMo Helix with Helm

View as Markdown

NeMo Helix is bundled in an all-in-one Helm chart for self-managed Kubernetes deployments. Use these guides to deploy the platform on local clusters such as minikube and kind, managed clusters such as EKS, AKS, GKE, and OKE, or on-prem Kubernetes.

Start with Prerequisites, then follow Install. The install guide pins the chart with NHX_HELM_CHART_VERSION and uses the nvidia/nemo-helix NGC org for chart and image access.
