Containerized Data Importer (CDI) is an utility designed to import Virtual Machine images for use with Kubevirt.
In this lab you'll play with CDI to import an existing VM to be started under KubeVirt.
Well done, you have completed the KubeVirt demo!
We hope you enjoyed it, for more information about KubeVirt, please do check https://kubevirt.io!

Steps
Experiment with CDI
Launch cluster and deploy KubeVirt
Wait for the Kubernetes cluster to be ready
Before we can start, we need to wait for the Kubernetes cluster to be ready (a command prompt will appear once it's ready).
Deploy KubeVirt
In this scenario, we'll go quickly over installing KubeVirt as it was covered already in the introduction scenario: 'First steps with KubeVirt'
We query GitHub's API to get the latest available release (click on the text to auto-execute the commands on the console):
export KUBEVIRT_VERSION=$(curl -s https://api.github.com/repos/kubevirt/kubevirt/releases/latest | jq -r .tag_name)
echo $KUBEVIRT_VERSION
Run the following command to deploy the KubeVirt Operator:
kubectl create -f https://github.com/kubevirt/kubevirt/releases/download/${KUBEVIRT_VERSION}/kubevirt-operator.yaml
This demo environment already runs within a virtualized environment, and to be able to run VMs here we need to pre-configure KubeVirt so it uses software-emulated virtualization instead of trying to use real hardware virtualization.
kubectl create configmap kubevirt-config -n kubevirt --from-literal debug.useEmulation=true
Now let's deploy KubeVirt by creating a Custom Resource that will trigger the 'operator' reaction and perform the deployment:
kubectl create -f https://github.com/kubevirt/kubevirt/releases/download/${KUBEVIRT_VERSION}/kubevirt-cr.yaml
Let's check the deployment:
kubectl get pods -n kubevirt
This will take a while until all the pods are running, retry the command until the output states that all fo them are running.
Once it's ready, it will show something similar to:
master $ kubectl get pods -n kubevirt

virt-operator-5649f67475-sw78k 1/1 Running 0 4m
Install Virtctl
virtctl
is a client utility that helps interact with VM's (start/stop/console, etc):
wget -O virtctl https://github.com/kubevirt/kubevirt/releases/download/${KUBEVIRT_VERSION}/virtctl-${KUBEVIRT_VERSION}-linux-amd64
chmod +x virtctl
Now everything is ready to continue and prepare CDI for launching a VM.
