GKE

Prerequisites​

  1. gcloud cli
  2. kubectl with correct context selected: pointing to the cluster you want to deploy Luna on.
  3. helm: the package manager for Kubernetes
  4. An existing zonal GKE standard (not Autopilot) cluster

Step 1(optional): Install Nvidia gpu driver for gpu workload​

kubectl apply -f https://raw.githubusercontent.com/GoogleCloudPlatform/container-engine-accelerators/master/nvidia-driver-installer/cos/daemonset-preloaded.yaml

Step 2: Deploy Luna​

Luna needs cert-manager running in the cluster. Deploy script tries to detect cert-manager in the cluster and installs cert-manager to cert-manager namespace otherwise.

To use Luna, workload identity must be enabled on the specified nodepool of the cluster. If it's not already enabled, the deployment script will prompt you to enable it during deployment.

    ./deploy.sh <gcp-project-name> <gke-cluster-name> <cluster-zone> <nodepool-name> <additional-helm-values(optional)>

Step 3: Verify Luna​

kubectl get all -n elotl

Step 4: Run some workloads!​

Follow our tutorial to understand value provided by Luna.

Step 5: Verify test pod launch and dynamic worker node addition/removal (while testing)​

kubectl get pods --selector=elotl-luna=true -o wide -w
kubectl get nodes -w

Cleanup​

helm uninstall elotl-luna --namespace=elotl
kubectl delete namespace elotl
gcloud container node-pools delete luna-nodepool --zone=$COMPUTE_REGION --cluster=$CLUSTER_NAME
