Request

{'DeleteReplacedRootVolume': 'boolean', 'ImageId': 'string'}

Response

{'ReplaceRootVolumeTask': {'DeleteReplacedRootVolume': 'boolean',
                           'ImageId': 'string',
                           'SnapshotId': 'string'}}

Replaces the EBS-backed root volume for a running instance with a new volume that is restored to the original root volume's launch state, that is restored to a specific snapshot taken from the original root volume, or that is restored from an AMI that has the same key characteristics as that of the instance.

For more information, see Replace a root volume in the Amazon Elastic Compute Cloud User Guide.

type InstanceId:

string

param InstanceId:

[REQUIRED]

The ID of the instance for which to replace the root volume.

type SnapshotId:

string

param SnapshotId:

The ID of the snapshot from which to restore the replacement root volume. The specified snapshot must be a snapshot that you previously created from the original root volume.

If you want to restore the replacement root volume to the initial launch state, or if you want to restore the replacement root volume from an AMI, omit this parameter.

type ClientToken:

string

param ClientToken:

Unique, case-sensitive identifier you provide to ensure the idempotency of the request. If you do not specify a client token, a randomly generated token is used for the request to ensure idempotency. For more information, see Ensuring idempotency.

This field is autopopulated if not provided.

type DryRun:

boolean

param DryRun:

Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

type TagSpecifications:

list

param TagSpecifications:

The tags to apply to the root volume replacement task.

(dict) --

The tags to apply to a resource when the resource is being created.

Note

The Valid Values lists all the resource types that can be tagged. However, the action you're using might not support tagging all of these resource types. If you try to tag a resource type that is unsupported for the action you're using, you'll get an error.
- ResourceType (string) --
  
  The type of resource to tag on creation.
- Tags (list) --
  
  The tags to apply to the resource.
  - (dict) --
    
    Describes a tag.
    - Key (string) --
      
      The key of the tag.
      
      Constraints: Tag keys are case-sensitive and accept a maximum of 127 Unicode characters. May not begin with aws:.
    - Value (string) --
      
      The value of the tag.
      
      Constraints: Tag values are case-sensitive and accept a maximum of 256 Unicode characters.

type ImageId:

string

param ImageId:

The ID of the AMI to use to restore the root volume. The specified AMI must have the same product code, billing information, architecture type, and virtualization type as that of the instance.

If you want to restore the replacement volume from a specific snapshot, or if you want to restore it to its launch state, omit this parameter.

type DeleteReplacedRootVolume:

boolean

param DeleteReplacedRootVolume:

Indicates whether to automatically delete the original root volume after the root volume replacement task completes. To delete the original root volume, specify true. If you choose to keep the original root volume after the replacement task completes, you must manually delete it when you no longer need it.

rtype:

dict

returns:
