如何使用aws cli获取特定实例的/ dev/sdf中挂载设备的volumeid？

我正在尝试将挂载在/ dev/sdf的设备的卷id获取到特定实例。如何使用aws cli获取特定实例的/ dev/sdf中挂载设备的volumeid？

命令： AWS EC2描述体积--filters名称= attachment.instance-ID，值= $ instance_id_main --region美西2 --output JSON

输出：

{ 
    "Volumes": [ 
     { 
      "AvailabilityZone": "us-west-2a", 
      "Attachments": [ 
       { 
        "AttachTime": "2017-06-15T12:59:18.000Z", 
        "InstanceId": "i-073cfdf5832e5a7ab", 
        "VolumeId": "vol-096ca253d37b3e42b", 
        "State": "attached", 
        "DeleteOnTermination": false, 
        "Device": "/dev/sdf" 
       } 
      ], 
      "Tags": [ 
       { 
        "Value": "NewVolume", 
        "Key": "Name" 
       } 
      ], 
      "Encrypted": false, 
      "VolumeType": "gp2", 
      "VolumeId": "vol-096ca253d37b3e42b", 
      "State": "in-use", 
      "Iops": 100, 
      "SnapshotId": "", 
      "CreateTime": "2017-06-15T12:39:06.687Z", 
      "Size": 5 
     }, 
     { 
      "AvailabilityZone": "us-west-2a", 
      "Attachments": [ 
       { 
        "AttachTime": "2017-06-15T12:57:46.000Z", 
        "InstanceId": "i-073cfdf5832e5a7ab", 
        "VolumeId": "vol-0189e6a20392bb709", 
        "State": "attached", 
        "DeleteOnTermination": true, 
        "Device": "/dev/sda1" 
       } 
      ], 
      "Tags": [ 
       { 
        "Value": "NewTesting", 
        "Key": "Name" 
       } 
      ], 
      "Encrypted": false, 
      "VolumeType": "gp2", 
      "VolumeId": "vol-0189e6a20392bb709", 
      "State": "in-use", 
      "Iops": 100, 
      "SnapshotId": "snap-0a642b1f5be55819a", 
      "CreateTime": "2017-06-15T12:57:46.027Z", 
      "Size": 8 
     } 
    ] 
} 

我试着用--query选项来描述在这个例子中给出的音量，然后我得到了下面的输出结果。

命令：

aws ec2 describe-volumes --filters Name=attachment.instance-id,Values=$instance_id_main --query 'Volumes[*].{ID:VolumeId,Tag:Tags}' --region us-west-2 --output json 

[ 
    { 
     "Tag": [ 
      { 
       "Value": "NewVolume", 
       "Key": "Name" 
      } 
     ], 
     "ID": "vol-096ca253d37b3e42b" 
    }, 
    { 
     "Tag": [ 
      { 
       "Value": "NewTesting", 
       "Key": "Name" 
      } 
     ], 
     "ID": "vol-0189e6a20392bb709" 
    } 
] 

然后我试图让附件，我得到了下面的错误。

命令：

aws ec2 describe-volumes --filters Name=attachment.instance-id,Values=$instance_id_main --query 'Volumes[*].{Attachments:Device[*]}' --region us-west-2 --output text 

输出：

[ 
    { 
     "Attachments": null 
    }, 
    { 
     "Attachments": null 
    } 
] 

任何想法，将不胜感激。
