get-invalidation

Description

Get the information about an invalidation.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

Synopsis

  get-invalidation
--distribution-id <value>
--id <value>
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--distribution-id (string)

The distribution's ID.

--id (string)

The identifier for the invalidation request, for example, IDFDVBD632BHDS5 .

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. 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

To get information about an invalidation

The following command retrieves an invalidation with the ID YNY2LI2BVJ4NJU for a CloudFront web distribution with the ID S11A16G5KZMEQD:

aws cloudfront get-invalidation --id YNY2LI2BVJ4NJU --distribution-id S11A16G5KZMEQD

The distribution ID is available in the output of create-distribution and list-distributions. The invalidation ID is available in the output of create-invalidation and list-invalidations.

Output:

{
    "Invalidation": {
        "Status": "Completed",
        "InvalidationBatch": {
            "Paths": {
                "Items": [
                    "/index.html",
                    "/error.html"
                ],
                "Quantity": 2
            },
            "CallerReference": "my-invalidation-2015-09-01"
        },
        "Id": "YNY2LI2BVJ4NJU",
        "CreateTime": "2015-08-31T21:15:52.042Z"
    }
}

Output

Invalidation -> (structure)

The invalidation's information. For more information, see Invalidation Complex Type .

Id -> (string)

The identifier for the invalidation request. For example: IDFDVBD632BHDS5 .

Status -> (string)

The status of the invalidation request. When the invalidation batch is finished, the status is Completed .

CreateTime -> (timestamp)

The date and time the invalidation request was first made.

InvalidationBatch -> (structure)

The current invalidation information for the batch request.

Paths -> (structure)

A complex type that contains information about the objects that you want to invalidate. For more information, see Specifying the Objects to Invalidate in the Amazon CloudFront Developer Guide .

Quantity -> (integer)

The number of invalidation paths specified for the objects that you want to invalidate.

Items -> (list)

A complex type that contains a list of the paths that you want to invalidate.

(string)

CallerReference -> (string)

A value that you specify to uniquely identify an invalidation request. CloudFront uses the value to prevent you from accidentally resubmitting an identical request. Whenever you create a new invalidation request, you must specify a new value for CallerReference and change other values in the request as applicable. One way to ensure that the value of CallerReference is unique is to use a timestamp , for example, 20120301090000 .

If you make a second invalidation request with the same value for CallerReference , and if the rest of the request is the same, CloudFront doesn't create a new invalidation request. Instead, CloudFront returns information about the invalidation request that you previously created with the same CallerReference .

If CallerReference is a value you already sent in a previous invalidation batch request but the content of any Path is different from the original request, CloudFront returns an InvalidationBatchAlreadyExists error.
