Describes the modifications made to your Reserved Instances. If no parameter is specified, information about all your Reserved Instances modification requests is returned. If a modification ID is specified, only information about the specific modification is returned.
For more information, see Modifying Reserved Instances in the Amazon EC2 User Guide .
Note
We are retiring EC2-Classic on August 15, 2022. We recommend that you migrate from EC2-Classic to a VPC. For more information, see Migrate from EC2-Classic to a VPC in the Amazon Elastic Compute Cloud User Guide .

describe-reserved-instances-modifications
is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate
argument.
When using --output text
and the --query
argument on a paginated response, the --query
argument must extract data from the results of the following query expressions: ReservedInstancesModifications

[--filters <value>]
[--reserved-instances-modification-ids <value>]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]
--filters
(list)
One or more filters.
client-token
- The idempotency token for the modification request.
create-date
- The time when the modification request was created.
effective-date
- The time when the modification becomes effective.
modification-result.reserved-instances-id
- The ID for the Reserved Instances created as part of the modification request. This ID is only available when the status of the modification isfulfilled
.
modification-result.target-configuration.availability-zone
- The Availability Zone for the new Reserved Instances.
modification-result.target-configuration.instance-count
- The number of new Reserved Instances.
modification-result.target-configuration.instance-type
- The instance type of the new Reserved Instances.
modification-result.target-configuration.platform
- The network platform of the new Reserved Instances (EC2-Classic
|EC2-VPC
).
reserved-instances-id
- The ID of the Reserved Instances modified.
reserved-instances-modification-id
- The ID of the modification request.
status
- The status of the Reserved Instances modification request (processing
|fulfilled
|failed
).
status-message
- The reason for the status.
update-date
- The time when the modification request was last updated.(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", ...]
}
...
]
--reserved-instances-modification-ids
(list)
IDs for the submitted modification request.
(string)
Syntax:
"string" "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
.
--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 .
--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 theNextToken
value in thestarting-token
argument of a subsequent command. Do not use theNextToken
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. 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.
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 .
