Upgrade

Note

This section applies to self-hosted installation only. To upgrade your cluster in SaaS, see the SaaS installation guide.

Before upgrade

Before proceeding with the upgrade, it's crucial to apply the specific prerequisites associated with your current version of NVIDIA Run:ai and every version in between up to the version you are upgrading to.

Helm

NVIDIA Run:ai requires Helm 3.14 or later. Before you continue, validate your installed helm client version. To install or upgrade Helm, see Installing Helm. If you are installing an air-gapped version of NVIDIA Run:ai, the NVIDIA Run:ai tar file contains the helm binary.

Software files

Connected

Run the helm command below:

helm repo add runai-backend https://runai.jfrog.io/artifactory/cp-charts-prod
helm repo update

Air-gapped

• Ask for a tar file runai-air-gapped-<NEW-VERSION>.tar.gz from NVIDIA Run:ai customer support. The file contains the new version you want to upgrade to. <NEW-VERSION> is the updated version of the NVIDIA Run:ai control plane.

• Upload the images as described here.

System and network requirements

Before upgrading the NVIDIA Run:ai control plane, validate that the latest system requirements and network requirements are met, as they can change from time to time.

Upgrade

To upgrade from 2.17 or later, run the following:

Connected

helm get values runai-backend -n runai-backend > runai_control_plane_values.yaml
helm upgrade runai-backend -n runai-backend runai-backend/control-plane --version "<VERSION>" -f runai_control_plane_values.yaml --reset-then-reuse-values

Air-gapped

helm get values runai-backend -n runai-backend > runai_control_plane_values.yaml
helm upgrade runai-backend control-plane-<NEW-VERSION>.tgz -n runai-backend  -f runai_control_plane_values.yaml --reset-then-reuse-values

Note

To upgrade to a specific version, modify the --version flag by specifying the desired <VERSION>. You can find all available versions by using the helm search repo command.

Upgrade cluster

System and network requirements

Before upgrading the NVIDIA Run:ai cluster, validate that the latest system requirements and network requirements are met, as they can change from time to time.

Note

It is highly recommended to upgrade the Kubernetes version together with the NVIDIA Run:ai cluster version, to ensure compatibility with latest supported version of your Kubernetes distribution.
