7.4.2.3.4. 使用命令行启用动态密钥注入

流程

1. 为 VirtualMachine 对象和 Secret 对象创建清单文件：

   apiVersion: kubevirt.io/v1
   kind: VirtualMachine
   metadata:
     name: example-vm
     namespace: example-namespace
   spec:
     dataVolumeTemplates:
     - apiVersion: cdi.kubevirt.io/v1beta1
       kind: DataVolume
       metadata:
         name: example-vm-disk
       spec:
         sourceRef:
           kind: DataSource
           name: rhel9
           namespace: openshift-virtualization-os-images
         storage:
           resources:
             requests:
               storage: 30Gi
     running: false
     template:
       metadata:
         labels:
           kubevirt.io/domain: example-vm
       spec:
         domain:
           cpu:
             cores: 1
             sockets: 2
             threads: 1
           devices:
             disks:
             - disk:
                 bus: virtio
               name: rootdisk
             - disk:
                 bus: virtio
               name: cloudinitdisk
             interfaces:
             - masquerade: {}
               name: default
             rng: {}
           features:
             smm:
               enabled: true
           firmware:
             bootloader:
               efi: {}
           resources:
             requests:
               memory: 8Gi
         evictionStrategy: LiveMigrate
         networks:
         - name: default
           pod: {}
         volumes:
         - dataVolume:
             name: example-volume
           name: example-vm-disk
           - cloudInitConfigDrive: <.>
               userData: |-
                 #cloud-config
                 user: cloud-user
                 password: <password>
                 chpasswd: { expire: False }
                 runcmd:
                   - [ setsebool, -P, virt_qemu_ga_manage_ssh, on ]
             name: cloudinitdisk
         accessCredentials:
           - sshPublicKey:
               propagationMethod:
                 qemuGuestAgent:
                   users: ["user1","user2","fedora"] <.>
               source:
                 secret:
                   secretName: authorized-keys <.>
   ---
   apiVersion: v1
   kind: Secret
   metadata:
     name: authorized-keys
   data:
     key:  |
         MIIEpQIBAAKCAQEAulqb/Y... <.>

   <.> 指定 cloudInitConfigDrive 来创建配置驱动器。<.> 指定用户名。<.> 指定 Secret 对象名称。<.> 粘贴公共 SSH 密钥。

2. 创建 VirtualMachine 和 Secret 对象：

   $ oc create -f <manifest_file>.yaml

3. 启动虚拟机：

   $ virtctl start vm example-vm -n example-namespace
