9.8.8. Updating multiple virtual machines

Procedure

1. Create a privileged service account by running the following commands:

   $ oc adm new-project kubevirt-api-lifecycle-automation

   $ oc create sa kubevirt-api-lifecycle-automation -n kubevirt-api-lifecycle-automation

   $ oc create clusterrolebinding kubevirt-api-lifecycle-automation --clusterrole=cluster-admin --serviceaccount=kubevirt-api-lifecycle-automation:kubevirt-api-lifecycle-automation

2. Determine the pull URL for the kubevirt-api-lifecycle image by running the following command:

   $ oc get csv -n openshift-cnv -l=operators.coreos.com/kubevirt-hyperconverged.openshift-cnv -ojson | jq '.items[0].spec.relatedImages[] | select(.name|test(".*kubevirt-api-lifecycle-automation.*")) | .image'

3. Deploy Kubevirt-Api-Lifecycle-Automation by creating a job object as shown in the following example:

   apiVersion: batch/v1
   kind: Job
   metadata:
    name: kubevirt-api-lifecycle-automation
    namespace: kubevirt-api-lifecycle-automation
   spec:
    template:
     spec:
      containers:
      - name: kubevirt-api-lifecycle-automation
        image: quay.io/openshift-virtualization/kubevirt-api-lifecycle-automation:v4.21
        imagePullPolicy: Always
        env:
        - name: MACHINE_TYPE_GLOB
          value: smth-glob9.10.0
        - name: RESTART_REQUIRED
          value: "true"
        - name: NAMESPACE
          value: "default"
        - name: LABEL_SELECTOR
          value: my-vm
        securityContext:
         allowPrivilegeEscalation: false
         capabilities:
          drop:
          - ALL
         privileged: false
         runAsNonRoot: true
         seccompProfile:
          type: RuntimeDefault
      restartPolicy: Never
      serviceAccountName: kubevirt-api-lifecycle-automation

   where:

   quay.io/openshift-virtualization/kubevirt-api-lifecycle-automation:v4.21

   Specifies the pull URL for your image. Replace the image value in this example with your pull URL for the image.

   MACHINE_TYPE_GLOB

   Specifies the pattern that is used to detect deprecated machine types that need to be upgraded. Replace the MACHINE_TYPE_GLOB value with your own pattern.

   RESTART_REQUIRED

   Specifies whether VMs should be restarted after the machine type is updated. If the RESTART_REQUIRED environment variable is set to true, VMs are restarted after the machine type is updated. If you do not want VMs to be restarted, set this value to false.

   NAMESPACE

   Specifies the namespace to look for VMs in. Leave the parameter empty for the job to go over all namespaces in the cluster.

   LABEL_SELECTOR

   Specifies which VMs receive the job action. If you want the job to go over all VMs in the cluster, do not assign a value to the parameter.
