Amazon Simple Systems Manager (SSM)

2017/10/19 - Amazon Simple Systems Manager (SSM) - 6 updated api methods

Changes  EC2 Systems Manager versioning support for Parameter Store. Also support for referencing parameter versions in SSM Documents.

DescribeParameters (updated) Link ¶
Changes (response)
{'Parameters': {'Version': 'long'}}

Get information about a parameter.

Request results are returned on a best-effort basis. If you specify MaxResults in the request, the response includes information up to the limit specified. The number of items returned, however, can be between zero and the value of MaxResults . If the service reaches an internal limit while processing the results, it stops the operation and returns the matching values up to that point and a NextToken . You can specify the NextToken in a subsequent call to get the next set of results.

Request results are returned on a best-effort basis. If you specify MaxResults in the request, the response includes information up to the limit specified. The number of items returned, however, can be between zero and the value of MaxResults . If the service reaches an internal limit while processing the results, it stops the operation and returns the matching values up to that point and a NextToken .

Response Syntax

{
    'Version': 123
}

Response Structure

  • (dict) --

    • Version (integer) --

      The new version number of a parameter. If you edit a parameter value, Parameter Store automatically creates a new version and assigns this new version a unique ID. You can reference a parameter version ID in API actions or in Systems Manager documents (SSM documents). By default, if you don't specify a specific version, the system returns the latest parameter value when a parameter is called.
