ALIYUN::ECS::SnapshotGroup - 资源编排

ALIYUN::ECS::SnapshotGroup类型用于为指定ECS实例中的云盘创建快照一致性组。快照一致性组包含一个或多个云盘对应的快照。

语法

{
  "Type": "ALIYUN::ECS::SnapshotGroup",
  "Properties": {
    "DiskIds": List,
    "Description": String,
    "ExcludeDiskIds": List,
    "InstanceId": String,
    "Name": String,
    "ResourceGroupId": String,
    "Tags": List
  }
}

属性

属性名称	类型	必须	允许更新	描述	约束
DiskIds	List	否	否	指定创建快照一致性组的云盘 ID。	在同可用区内支持跨实例设置多个云盘 ID。一个快照一致性组内最多支持设置 16 块总大小不超过 32 TiB 的云盘。说明该参数不可与`ExcludeDiskIds`同时设置。如果您设置了`InstanceId`，则该参数只能设置指定实例内已挂载的云盘，不再支持设置多个跨实例的云盘 ID。
Description	String	否	是	描述。	长度为 2～256 个字符，不能以`http://`或`https://`开头。
ExcludeDiskIds	List	否	否	实例中不需要创建快照的云盘 ID。	指定云盘 ID 后，创建的快照一致性组将不包含该云盘对应的快照。最多支持配置16个快照的云盘 ID。默认值：空，表示为实例中的所有云盘创建快照。说明该参数不可与`DiskIds`同时设置。
InstanceId	String	否	否	实例 ID。	无
Name	String	否	是	快照一致性组名称。	长度为 2~128 个英文或中文字符。必须以大小写字母或中文开头，不能以`http://`或`https://`开头，可以包含数字、半角句号（.）、下划线（_）、短划线（-）或者半角冒号（:）。
ResourceGroupId	String	否	否	快照一致性组所属的资源组 ID。	无
Tags	List	否	是	标签。	最多支持添加20个标签。更多信息，请参见Tags属性。

Tags语法

"Tags": [
  {
    "Value": String,
    "Key": String
  }

返回值

Fn::GetAtt

SnapshotGroupId：快照一致性组 ID。

Parameters:
  DiskIds:
    AssociationPropertyMetadata:
      Parameter:
        Type: String
        Description:
          en: The ID of cloud disk for which you want to create snapshots.
        Required: false
    AssociationProperty: List[Parameter]
    Type: Json
    Description:
      en: |-
        The IDs of cloud disk for which you want to create snapshots. You can specify multiple cloud disk IDs across instances within the same zone. The length of the list ranges from 1 to 16. A single snapshot-consistent group can contain snapshots of up to 16 cloud disks whose total disk size does not exceed 32 TiB.
        Take note of the following items:
        You cannot specify both DiskIds and ExcludeDiskIdin the same request.
        If InstanceId is set, you can use DiskIds to specify only cloud disks attached to the instance specified by InstanceId, and you cannot use DiskIds to specify cloud disks attached to multiple instances.
    Required: false
  InstanceId:
    Type: String
    AssociationProperty: ALIYUN::ECS::Instance::InstanceId
    Description:
      en: The instance ID.
    Required: false
  Name:
    Type: String
    Description:
      en: The name of the snapshot-consistent group. The name must be 2 to 128 characters in length. The name can contain letters, digits, periods (.), underscores (_), hyphens (-), and colons (:). It must start with a letter and cannot start with http:// or https://.
    Required: false
