deploy kubevirt

Use kubectl to deploy the KubeVirt operator:

export VERSION=$(curl -s https://storage.googleapis.com/kubevirt-prow/release/kubevirt/kubevirt/stable.txt)

echo $VERSION kubectl create -f "https://github.com/kubevirt/kubevirt/releases/download/${VERSION}/kubevirt-operator.yaml"

Again use kubectl to deploy the KubeVirt custom resource definitions:

kubectl create -f "https://github.com/kubevirt/kubevirt/releases/download/${VERSION}/kubevirt-cr.yaml"

Check the deployment:

kubectl get kubevirt.kubevirt.io/kubevirt -n kubevirt -o=jsonpath="{.status.phase}"
