Implements IConstruct, IDependable, IInspectable

A CloudFormation AWS::IAM::ManagedPolicy.

Creates a new managed policy for your AWS account .

This operation creates a policy version with a version identifier of v1 and sets v1 as the policy's default version. For more information about policy versions, see Versioning for managed policies in the IAM User Guide .

As a best practice, you can validate your IAM policies. To learn more, see Validating IAM policies in the IAM User Guide .

For more information about managed policies in general, see Managed policies and inline policies in the IAM User Guide .

Example

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_iam as iam } from 'aws-cdk-lib';

declare const policyDocument: any;
const cfnManagedPolicy = new iam.CfnManagedPolicy(this, 'MyCfnManagedPolicy', {
  policyDocument: policyDocument,

  // the properties below are optional
  description: 'description',
  groups: ['groups'],
  managedPolicyName: 'managedPolicyName',
  path: 'path',
  roles: ['roles'],
  users: ['users'],
});

Initializer

new CfnManagedPolicy(scope: Construct, id: string, props: CfnManagedPolicyProps)

Parameters

  • scope Construct — - scope in which this resource is defined.
  • id string — - scoped id of the resource.
  • props CfnManagedPolicyProps — - resource properties.

Create a new AWS::IAM::ManagedPolicy.

Construct Props

NameTypeDescription
policyDocumentanyThe JSON policy document that you want to use as the content for the new policy.
description?stringA friendly description of the policy.
groups?string[]The name (friendly name, not ARN) of the group to attach the policy to.
managedPolicyName?stringThe friendly name of the policy.
path?stringThe path for the policy.
roles?string[]The name (friendly name, not ARN) of the role to attach the policy to.
users?string[]The name (friendly name, not ARN) of the IAM user to attach the policy to.

policyDocument

Type: any

The JSON policy document that you want to use as the content for the new policy.

You must provide policies in JSON format in IAM. However, for AWS CloudFormation templates formatted in YAML, you can provide the policy in JSON or YAML format. AWS CloudFormation always converts a YAML policy to JSON format before submitting it to IAM.

The maximum length of the policy document that you can pass in this operation, including whitespace, is listed below. To view the maximum character counts of a managed policy with no whitespaces, see IAM and AWS STS character quotas .

To learn more about JSON policy grammar, see Grammar of the IAM JSON policy language in the IAM User Guide .

The regex pattern used to validate this parameter is a string of characters consisting of the following:

  • Any printable ASCII character ranging from the space character ( \ u0020 ) through the end of the ASCII character range
  • The printable characters in the Basic Latin and Latin-1 Supplement character set (through \ u00FF )
  • The special characters tab ( \ u0009 ), line feed ( \ u000A ), and carriage return ( \ u000D )

description?

Type: string (optional)

A friendly description of the policy.

Typically used to store information about the permissions defined in the policy. For example, "Grants access to production DynamoDB tables."

The policy description is immutable. After a value is assigned, it cannot be changed.


groups?

Type: string[] (optional)

The name (friendly name, not ARN) of the group to attach the policy to.

This parameter allows (through its regex pattern ) a string of characters consisting of upper and lowercase alphanumeric characters with no spaces. You can also include any of the following characters: _+=,.@-


managedPolicyName?

Type: string (optional)

The friendly name of the policy.

If you specify a name, you cannot perform updates that require replacement of this resource. You can perform updates that require no or some interruption. If you must replace the resource, specify a new name.

If you specify a name, you must specify the CAPABILITY_NAMED_IAM value to acknowledge your template's capabilities. For more information, see Acknowledging IAM Resources in AWS CloudFormation Templates .

Naming an IAM resource can cause an unrecoverable error if you reuse the same template in multiple Regions. To prevent this, we recommend using Fn::Join and AWS::Region to create a Region-specific name, as in the following example: {"Fn::Join": ["", [{"Ref": "AWS::Region"}, {"Ref": "MyResourceName"}]]} .


path?

Type: string (optional)

The path for the policy.

For more information about paths, see IAM identifiers in the IAM User Guide .

This parameter is optional. If it is not included, it defaults to a slash (/).

This parameter allows (through its regex pattern ) a string of characters consisting of either a forward slash (/) by itself or a string that must begin and end with forward slashes. In addition, it can contain any ASCII character from the ! ( \ u0021 ) through the DEL character ( \ u007F ), including most punctuation characters, digits, and upper and lowercased letters.

You cannot use an asterisk (*) in the path name.


roles?

Type: string[] (optional)

The name (friendly name, not ARN) of the role to attach the policy to.

This parameter allows (per its regex pattern ) a string of characters consisting of upper and lowercase alphanumeric characters with no spaces. You can also include any of the following characters: _+=,.@-

If an external policy (such as AWS::IAM::Policy or AWS::IAM::ManagedPolicy ) has a Ref to a role and if a resource (such as AWS::ECS::Service ) also has a Ref to the same role, add a DependsOn attribute to the resource to make the resource depend on the external policy. This dependency ensures that the role's policy is available throughout the resource's lifecycle. For example, when you delete a stack with an AWS::ECS::Service resource, the DependsOn attribute ensures that AWS CloudFormation deletes the AWS::ECS::Service resource before deleting its role's policy.


users?

Type: string[] (optional)

The name (friendly name, not ARN) of the IAM user to attach the policy to.

This parameter allows (through its regex pattern ) a string of characters consisting of upper and lowercase alphanumeric characters with no spaces. You can also include any of the following characters: _+=,.@-

ref

Type: string

Return a string that will be resolved to a CloudFormation { Ref } for this element.

If, by any chance, the intrinsic reference of a resource is not a string, you could coerce it to an IResolvable through Lazy.any({ produce: resource.ref }).


stack

Type: Stack

The stack in which this element is defined.

CfnElements must be defined within a stack scope (directly or indirectly).


description?

Type: string (optional)

A friendly description of the policy.

The name (friendly name, not ARN) of the group to attach the policy to.

This parameter allows (through its regex pattern ) a string of characters consisting of upper and lowercase alphanumeric characters with no spaces. You can also include any of the following characters: _+=,.@-


managedPolicyName?

Type: string (optional)

The friendly name of the policy.

If you specify a name, you cannot perform updates that require replacement of this resource. You can perform updates that require no or some interruption. If you must replace the resource, specify a new name.

If you specify a name, you must specify the CAPABILITY_NAMED_IAM value to acknowledge your template's capabilities. For more information, see Acknowledging IAM Resources in AWS CloudFormation Templates .

Naming an IAM resource can cause an unrecoverable error if you reuse the same template in multiple Regions. To prevent this, we recommend using Fn::Join and AWS::Region to create a Region-specific name, as in the following example: {"Fn::Join": ["", [{"Ref": "AWS::Region"}, {"Ref": "MyResourceName"}]]} .


path?

Type: string (optional)

The path for the policy.

For more information about paths, see IAM identifiers in the IAM User Guide .

This parameter is optional. If it is not included, it defaults to a slash (/).

This parameter allows (through its regex pattern ) a string of characters consisting of either a forward slash (/) by itself or a string that must begin and end with forward slashes. In addition, it can contain any ASCII character from the ! ( \ u0021 ) through the DEL character ( \ u007F ), including most punctuation characters, digits, and upper and lowercased letters.

You cannot use an asterisk (*) in the path name.


roles?

Type: string[] (optional)

The name (friendly name, not ARN) of the role to attach the policy to.

This parameter allows (per its regex pattern ) a string of characters consisting of upper and lowercase alphanumeric characters with no spaces. You can also include any of the following characters: _+=,.@-

If an external policy (such as AWS::IAM::Policy or AWS::IAM::ManagedPolicy ) has a Ref to a role and if a resource (such as AWS::ECS::Service ) also has a Ref to the same role, add a DependsOn attribute to the resource to make the resource depend on the external policy. This dependency ensures that the role's policy is available throughout the resource's lifecycle. For example, when you delete a stack with an AWS::ECS::Service resource, the DependsOn attribute ensures that AWS CloudFormation deletes the AWS::ECS::Service resource before deleting its role's policy.


users?

Type: string[] (optional)

The name (friendly name, not ARN) of the IAM user to attach the policy to.

This parameter allows (through its regex pattern ) a string of characters consisting of upper and lowercase alphanumeric characters with no spaces. You can also include any of the following characters: _+=,.@-

addDeletionOverride(path)

public addDeletionOverride(path: string): void

Parameters

  • path string — The path of the value to delete.

Syntactic sugar for addOverride(path, undefined).


addDependency(target)

public addDependency(target: CfnResource): void

Parameters

  • target CfnResource

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.


addDependsOn(target)⚠️

public addDependsOn(target: CfnResource): void

⚠️ Deprecated: use addDependency

Parameters

  • target CfnResource

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.


addMetadata(key, value)

public addMetadata(key: string, value: any): void

Parameters

  • key string
  • value any

Add a value to the CloudFormation Resource Metadata.

See also: [https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.)


addOverride(path, value)

public addOverride(path: string, value: any): void

Parameters

  • path string — - The path of the property, you can use dot notation to override values in complex types.
  • value any — - The value.

Adds an override to the synthesized CloudFormation resource.

To add a property override, either use addPropertyOverride or prefix path with "Properties." (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example,

cfnResource.addOverride('Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes', ['myattribute']);
cfnResource.addOverride('Properties.GlobalSecondaryIndexes.1.ProjectionType', 'INCLUDE');

would add the overrides

"Properties": {
  "GlobalSecondaryIndexes": [
    {
      "Projection": {
        "NonKeyAttributes": [ "myattribute" ]
        ...
      }
      ...
    },
    {
      "ProjectionType": "INCLUDE"
      ...
    },
  ]
  ...
}

The value argument to addOverride will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.


addPropertyDeletionOverride(propertyPath)

public addPropertyDeletionOverride(propertyPath: string): void

Parameters

  • propertyPath string — The path to the property.

Adds an override that deletes the value of a property from the resource definition.


addPropertyOverride(propertyPath, value)

public addPropertyOverride(propertyPath: string, value: any): void

Parameters

  • propertyPath string — The path of the property.
  • value any — The value.

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).


applyRemovalPolicy(policy?, options?)

public applyRemovalPolicy(policy?: RemovalPolicy, options?: RemovalPolicyOptions): void

Parameters

  • policy RemovalPolicy
  • options RemovalPolicyOptions

Sets the deletion policy of the resource based on the removal policy specified.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you've removed it from the CDK application or because you've made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN). In some cases, a snapshot can be taken of the resource prior to deletion (RemovalPolicy.SNAPSHOT). A list of resources that support this policy can be found in the following link:

See also: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-attribute-deletionpolicy.html#aws-attribute-deletionpolicy-options


getAtt(attributeName, typeHint?)

public getAtt(attributeName: string, typeHint?: ResolutionTypeHint): Reference

Parameters

  • attributeName string — The name of the attribute.
  • typeHint ResolutionTypeHint

Returns

  • Reference

Returns a token for an runtime attribute of this resource.

Ideally, use generated attribute accessors (e.g. resource.arn), but this can be used for future compatibility in case there is no generated attribute.


getMetadata(key)

public getMetadata(key: string): any

Parameters

  • key string

Returns

  • any

Retrieve a value value from the CloudFormation Resource Metadata.

See also: [https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.)
