describe-replace-root-volume-tasks¶

Description¶

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

Synopsis¶

  describe-replace-root-volume-tasks
[--replace-root-volume-task-ids <value>]
[--filters <value>]
[--dry-run | --no-dry-run]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

Options¶

--replace-root-volume-task-ids (list)

The ID of the root volume replacement task to view.

(string)

Syntax:

"string" "string" ...

--filters (list)

Filter to use:

instance-id - The ID of the instance for which the root volume replacement task was created.

(structure)

A filter name and value pair that is used to return a more specific list of results from a describe operation. Filters can be used to match a set of resources by specific criteria, such as tags, attributes, or IDs.

If you specify multiple filters, the filters are joined with an AND , and the request returns only results that match all of the specified filters.

Name -> (string)

The name of the filter. Filter names are case-sensitive.

Values -> (list)

The filter values. Filter values are case-sensitive. If you specify multiple values for a filter, the values are joined with an OR , and the request returns all results that match any of the specified values.

(string)

Shorthand Syntax:

Name=string,Values=string,string ...

JSON Syntax:

[
  {
    "Name": "string",
    "Values": ["string", ...]
  }
  ...
]

--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 .

--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.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command’s output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command’s output. If the total number of items available is more than the value specified, a NextToken is provided in the command’s output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--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 view information about a specific root volume replacement task

The following describe-replace-root-volume-tasks example describes root volume replacement task replacevol-0111122223333abcd.

aws ec2 describe-replace-root-volume-tasks \
    --replace-root-volume-task-ids replacevol-0111122223333abcd

Output:

{
    "ReplaceRootVolumeTasks": [
        {
            "ReplaceRootVolumeTaskId": "replacevol-0111122223333abcd",
            "Tags": [],
            "InstanceId": "i-0123456789abcdefa",
            "TaskState": "succeeded",
            "StartTime": "2022-03-14T15:16:28Z",
            "CompleteTime": "2022-03-14T15:16:52Z"
        }
    ]
}

Example 2: To view information about all root volume replacement tasks for a specific instance

The following describe-replace-root-volume-tasks example describes all of the root volume replacement tasks for instance i-0123456789abcdefa.

aws ec2 describe-replace-root-volume-tasks \
    --filters Name=instance-id,Values=i-0123456789abcdefa

Output:

{
    "ReplaceRootVolumeTasks": [
        {
            "ReplaceRootVolumeTaskId": "replacevol-0111122223333abcd",
            "Tags": [],
            "InstanceId": "i-0123456789abcdefa",
            "TaskState": "succeeded",
            "StartTime": "2022-03-14T15:06:38Z",
            "CompleteTime": "2022-03-14T15:07:03Z"
        },
        {
            "ReplaceRootVolumeTaskId": "replacevol-0444455555555abcd",
            "Tags": [],
            "InstanceId": "i-0123456789abcdefa",
            "TaskState": "succeeded",
            "StartTime": "2022-03-14T15:16:28Z",
            "CompleteTime": "2022-03-14T15:16:52Z"
        }
    ]
}
