Chapter 5. Provision devices

Procedure

1. Request a new Red Hat Edge Manager agent enrollment configuration and store it in a file called config.yaml by running the following command:

   flightctl certificate request --signer=enrollment --expiration=365d --output=embedded > config.yaml

2. Create a cloud configuration user data file called cloud-config.yaml that places the agent configuration in the correct location on the first boot by running the following command:

   cat <<EOF > cloud-config.yaml
   #cloud-config
   write_files:
   - path: /etc/flightctl/config.yaml
     content: $(cat config.yaml | base64 -w0)
     encoding: b64
   EOF

3. Create a Kubernetes Secret that contains the cloud configuration user data file:

   oc create secret generic enrollment-secret --from-file=userdata=cloud-config.yaml

Procedure

1. Create a file that has the VirtualMachine resource manifest by running the following command:

   cat <<EOF > my-bootc-vm.yaml
   apiVersion: kubevirt.io/v1
   kind: VirtualMachine
   metadata:
     name: my-bootc-vm
   spec:
     runStrategy: RerunOnFailure
     template:
       spec:
         domain:
           cpu:
             cores: 1
           memory:
             guest: 1024M
           devices:
             disks:
               - name: containerdisk
                 disk:
                   bus: virtio
               - name: cloudinitdisk
                 disk:
                   bus: virtio
         volumes:
           - name: containerdisk
             containerDisk:
               image: ${OCI_DISK_IMAGE_REPO}:${OCI_IMAGE_TAG}
           - name: cloudinitdisk
             cloudInitConfigDrive:
               secretRef:
                 name: enrollment-secret
   EOF

2. Apply the resource manifest to your cluster by running the following command:

   oc apply -f my-bootc-vm.yaml
