7.5.2.2.3. 使用命令行在创建虚拟机时添加密钥

流程

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

   清单示例

   apiVersion: kubevirt.io/v1
   kind: VirtualMachine
   metadata:
     name: example-vm
     namespace: example-namespace
   spec:
     dataVolumeTemplates:
       - metadata:
           name: example-vm-volume
         spec:
           sourceRef:
             kind: DataSource
             name: rhel9
             namespace: openshift-virtualization-os-images
           storage:
             resources: {}
     instancetype:
       name: u1.medium
     preference:
       name: rhel.9
     running: true
     template:
       spec:
         domain:
           devices: {}
         volumes:
           - dataVolume:
               name: example-vm-volume
             name: rootdisk
           - cloudInitNoCloud:
               userData: |-
                 #cloud-config
                 user: cloud-user
             name: cloudinitdisk
         accessCredentials:
           - sshPublicKey:
               propagationMethod:
                 noCloud: {}
               source:
                 secret:
                   secretName: authorized-keys
   ---
   apiVersion: v1
   kind: Secret
   metadata:
     name: authorized-keys
   data:
     key: c3NoLXJzYSB...

   • spec.template.spec.volumes.cloudInitNoCloud 指定 cloudInitNoCloud 数据源。
   • spec.template.spec.accessCredentials.sshPublicKey.source.secret.secretName 指定 Secret 对象名称。
   • data.key 指定公共 SSH 密钥。

2. 运行以下命令来创建 VirtualMachine 和 Secret 对象：

   $ oc create -f <manifest_file>.yaml

3. 运行以下命令来启动虚拟机：

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