我正在尝试为我的ami附加更多的卷，这是我的构建器部分，

 Contains(container, a);

请帮助。

这将为您和其他10Gb磁盘提供资源：

{
   "builders" : [
      {
         "type" : "amazon-ebs",
         "instance_type" : "t2.micro",
         "ssh_username" : "ubuntu",
         "ami_name" : "packer-ES-{{timestamp}}",
         "source_ami_filter": {
            "filters": {
              "virtualization-type": "hvm",
              "name": "ubuntu/images/*ubuntu-xenial-16.04-amd64-server-*",
              "root-device-type": "ebs"
            },
            "owners": ["099720109477"],
            "most_recent": true
         },
         "launch_block_device_mappings" : [
            {
               "device_name" : "/dev/sdb",
               "delete_on_termination" : true,
               "volume_size" : 10,
               "volume_type" : "gp2"
            }
         ],
         "ami_block_device_mappings" : [
            {
               "device_name" : "/dev/sdb",
               "delete_on_termination" : true,
               "volume_type" : "gp2"
            }
         ]
      }
   ],
   "provisioners": [
     {
       "type": "shell",
       "inline": [
         "lsblk",
         "df -h"
       ]
     }
   ]
}

运行此命令，您将看到：

    ]
}

如果您不需要在sdb上设置任何内容，则可以完全删除launch_device_mappings部分，然后将volume_size移动到ami_device_mappings中。
