AWS::VerifiedPermissions::PolicyStore

Creates a policy store. A policy store is a container for policy resources. You can create a separate policy store for each of your applications.

Syntax

To declare this entity in your Amazon CloudFormation template, use the following syntax:

JSON

{
  "Type" : "AWS::VerifiedPermissions::PolicyStore",
  "Properties" : {
      "Description" : String,
      "Schema" : SchemaDefinition,
      "ValidationSettings" : ValidationSettings
    }
}

YAML

Type: AWS::VerifiedPermissions::PolicyStore
Properties:
  Description: String
  Schema: 
    SchemaDefinition
  ValidationSettings: 
    ValidationSettings

Properties

Description

Descriptive text that you can provide to help with identification of the current policy store.

Required: No

Type: String

Minimum: 0

Maximum: 150

Update requires: No interruption

Schema

Creates or updates the policy schema in a policy store. Cedar can use the schema to validate any Cedar policies and policy templates submitted to the policy store. Any changes to the schema validate only policies and templates submitted after the schema change. Existing policies and templates are not re-evaluated against the changed schema. If you later update a policy, then it is evaluated against the new schema at that time.

Required: No

Type: SchemaDefinition

Update requires: No interruption

ValidationSettings

Specifies the validation setting for this policy store.

Currently, the only valid and required value is Mode.

Important

We recommend that you turn on STRICT mode only after you define a schema. If a schema doesn't exist, then STRICT mode causes any policy to fail validation, and Verified Permissions rejects the policy. You can turn off validation by using the UpdatePolicyStore. Then, when you have a schema defined, use UpdatePolicyStore again to turn validation back on.

Required: Yes

Type: ValidationSettings

Update requires: No interruption

Return values

Ref

When you pass the logical ID of this resource to the intrinsic Ref function, Ref returns the unique id of the new or updated policy store. For example:

{ "Ref": "PSEXAMPLEabcdefg111111" }

For more information about using the Ref function, see Ref.

Fn::GetAtt

The Fn::GetAtt intrinsic function returns a value for a specified attribute of this type. The following are the available attributes and sample return values.

For more information about using the Fn::GetAtt intrinsic function, see Fn::GetAtt.

Arn

The Amazon Resource Name (ARN) of the new or updated policy store.

PolicyStoreId

The unique ID of the new or updated policy store.

Examples

Creating a policy store with a schema and verification enabled

The following example creates a policy store that is configured with a schema and policy validation against that schema turned on.
