PutResourcePolicy - Amazon Comprehend

PutResourcePolicy

Attaches a resource-based policy to a custom model. You can use this policy to authorize an entity in another AWS account to import the custom model, which replicates it in Amazon Comprehend in their account.

Request Syntax

{ "PolicyRevisionId": "string", "ResourceArn": "string", "ResourcePolicy": "string" }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

PolicyRevisionId

The revision ID that Amazon Comprehend assigned to the policy that you are updating. If you are creating a new policy that has no prior version, don't use this parameter. Amazon Comprehend creates the revision ID for you.

Type: String

Length Constraints: Maximum length of 64.

Pattern: [0-9A-Fa-f]+

Required: No

ResourceArn

The Amazon Resource Name (ARN) of the custom model to attach the policy to.

Type: String

Length Constraints: Maximum length of 256.

Pattern: arn:aws(-[^:]+)?:comprehend:[a-zA-Z0-9-]*:[0-9]{12}:(document-classifier|entity-recognizer)/[a-zA-Z0-9](-*[a-zA-Z0-9])*(/version/[a-zA-Z0-9](-*[a-zA-Z0-9])*)?

Required: Yes

ResourcePolicy

The JSON resource-based policy to attach to your custom model. Provide your JSON as a UTF-8 encoded string without line breaks. To provide valid JSON for your policy, enclose the attribute names and values in double quotes. If the JSON body is also enclosed in double quotes, then you must escape the double quotes that are inside the policy:

"{\"attribute\": \"value\", \"attribute\": [\"value\"]}"

To avoid escaping quotes, you can use single quotes to enclose the policy and double quotes to enclose the JSON names and values:

'{"attribute": "value", "attribute": ["value"]}'

Examples

Example resource-based policy for a custom model

The following example shows a resource-based policy for a custom model in Amazon Comprehend. The policy allows an entity in another AWS account to import the model that the policy is attached to. The policy specifies the authorized entity for the Principal attribute, and it specifies the ARN of the model version for the Resource attribute.

{ "Version": "2017-01-01", "Statement": [ { "Effect": "Allow", "Action": "comprehend:ImportModel", "Resource": [ "arn:aws:comprehend:us-west-2:111122223333:document-classifier/foo/version/*" ], "Principal": { "AWS": "arn:aws:iam::444455556666:root" } } ] }
