# GPU CloudImage

# Preparation

Install nvidia driver on your host.
Install the latest version of sealer on your host.

# How to check the result

Check the pod status to run kubectl get pods -n kube-system nvidia-device-plugin, you can find the pod in Running status.
Get the node details to run kubectl describe node, if nvidia.com/gpu shows on 'Allocated resources' section,you get a k8s cluster with GPU.
