See ‘aws help’ for descriptions of global parameters.

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.

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.

(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 256 Unicode characters.

--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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

Example 1: To restore a root volume to its initial launch state

The following create-replace-root-volume-task example restores the root volume of instance i-0123456789abcdefa to its initial launch state.

aws ec2 create-replace-root-volume-task \
    --instance-id i-0123456789abcdefa

Output:

{
    "ReplaceRootVolumeTask":
    {
        "InstanceId": "i-0123456789abcdefa",
            "ReplaceRootVolumeTaskId": "replacevol-0111122223333abcd",
            "TaskState": "pending",
            "StartTime": "2022-03-14T15:06:38Z",
            "Tags": []
    }
}

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

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

The following create-replace-root-volume-task example restores the root volume of instance i-0123456789abcdefa to snapshot snap-0abcdef1234567890.

aws ec2 create-replace-root-volume-task \
    --instance-id i-0123456789abcdefa \
    --snapshot-id  snap-0abcdef1234567890

Output:

{
    "ReplaceRootVolumeTask":
    {
        "InstanceId": "i-0123456789abcdefa",
        "ReplaceRootVolumeTaskId": "replacevol-0555566667777abcd",
        "TaskState": "pending",
        "StartTime": "2022-03-14T15:16:28Z",
        "Tags": []
    }
}
