create-replace-root-volume-task¶

Description¶

Creates a root volume replacement task for an Amazon EC2 instance. The root volume can either be restored to its initial launch state, or it can be restored using a specific snapshot.

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

Synopsis¶

  create-replace-root-volume-task
--instance-id <value>
[--snapshot-id <value>]
[--client-token <value>]
[--dry-run | --no-dry-run]
[--tag-specifications <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--instance-id (string)

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

--snapshot-id (string)

The ID of the snapshot from which to restore the replacement root volume. If you want to restore the volume to the initial launch state, omit this parameter.

--client-token (string)

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 .

--dry-run | --no-dry-run (boolean)

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 .

--tag-specifications (list)

The tags to apply to the root volume replacement task.

(structure)

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

ResourceType -> (string)

The type of resource to tag on creation.

Tags -> (list)

The tags to apply to the resource.

(structure)

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 255 Unicode characters.

Shorthand Syntax:

ResourceType=string,Tags=[{Key=string,Value=string},{Key=string,Value=string}] ...

]

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Examples¶

Example 1: To restore the root volume to its initial state

The following create-replace-root-volume-task example restores the root volume of the specified instance to its initial state.

aws ec2 create-replace-root-volume-task \
    --instance-id i-1234567890abcdef0

Output:

{
    "ReplaceRootVolumeTask": {
        "ReplaceRootVolumeTaskId": "replacevol-05efec875b94ae34d",
        "InstanceId": "i-1234567890abcdef0
        "TaskState": "pending",
        "StartTime": "2021-09-16T00:19:30Z",
        "Tags": []
    }
}

For more information, see Replace an Amazon EBS volume in the Amazon EC2 User Guide.

Example 2: To restore the root volume to a specific snapshot

The following create-replace-root-volume-task example replaces the root volume of the specified instance with the specified snapshot.

aws ec2 create-replace-root-volume-task \
    --instance-id i-1234567890abcdef0 \
    --snapshot-id snap-9876543210abcdef0

Output:

{
    "ReplaceRootVolumeTask": {
        "ReplaceRootVolumeTaskId": "replacevol-05efec875b94ae34d",
        "InstanceId": "i-1234567890abcdef0
        "TaskState": "pending",
        "StartTime": "2021-09-16T00:19:30Z",
        "Tags": []
    }
}

failing - the replacement task is in the process of failing.

failed - the replacement task has failed but the original root volume is still attached.

failing-detached - the replacement task is in the process of failing. The instance might have no root volume attached.
