Upgrade Run:ai¶

Preparations¶

Upgrade to Version 2.9¶

Before upgrading the control plane, run:

kubectl delete --namespace runai-backend --all \
    deployments,statefulset,svc,ing,ServiceAccount
kubectl delete svc -n kube-system runai-cluster-kube-prometh-kubelet

Delete all secrets in the runai-backend namespace except the helm secret (the secret of type helm.sh/release.v1).

Before version 2.9, the Run:ai installation, by default, included NGINX. It was possible to disable this installation. if NGINX is disabled in your current installation then do not run the following 2 lines.

kubectl delete ValidatingWebhookConfiguration runai-backend-nginx-ingress-admission
kubectl delete ingressclass nginx 

Next, install NGINX as described here

Then upgrade the control plane as described in the next section.

Upgrade the Control Plane¶

If you have customized the backend values file in the older version, save it now by running

helm get values runai-backend -n runai-backend > old-be-values.yaml

Generate a new backend values file as described here. Change the new file with the above customization if relevant.

Run the helm command below.

helm repo add runai-backend https://backend-charts.storage.googleapis.com
helm repo update
helm upgrade runai-backend -n runai-backend runai-backend/runai-backend -f runai-backend-values.yaml

helm upgrade runai-backend runai-backend/runai-backend-<version>.tgz -n \
    runai-backend  -f runai-backend-values.yaml

Upgrade Cluster¶

kubectl apply -f runai-crds.yaml
helm get values runai-cluster -n runai > values.yaml
helm upgrade runai-cluster -n runai runai-cluster-<version>.tgz -f values.yaml
