Example:

# The code below shows an example of how to instantiate this type.
# The values are placeholders you should change.
import aws_cdk.aws_iam as iam

# policy_document: Any

cfn_group = iam.CfnGroup(self, "MyCfnGroup",
    group_name="groupName",
    managed_policy_arns=["managedPolicyArns"],
    path="path",
    policies=[iam.CfnGroup.PolicyProperty(
        policy_document=policy_document,
        policy_name="policyName"
    )]
)

Create a new AWS::IAM::Group.

Parameters
  • scope (Construct) –

    • scope in which this resource is defined.

  • id (str) –

    • scoped id of the resource.

  • group_name (Optional[str]) – The name of the group to create. Do not include the path in this value. The group name must be unique within the account. Group names are not distinguished by case. For example, you cannot create groups named both “ADMINS” and “admins”. If you don’t specify a name, AWS CloudFormation generates a unique physical ID and uses that ID for the group name. .. epigraph:: 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 . .. epigraph:: 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"}]]} .

  • managed_policy_arns (Optional[Sequence[str]]) – The Amazon Resource Name (ARN) of the IAM policy you want to attach. For more information about ARNs, see Amazon Resource Names (ARNs) in the AWS General Reference .

  • path (Optional[str]) – The path to the group. 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.

  • policies (Union[IResolvable, Sequence[Union[IResolvable, PolicyProperty, Dict[str, Any]]], None]) –

    Adds or updates an inline policy document that is embedded in the specified IAM group. To view AWS::IAM::Group snippets, see Declaring an IAM Group Resource . .. epigraph:: The name of each inline policy for a role, user, or group must be unique. If you don’t choose unique names, updates to the IAM identity will fail. For information about limits on the number of inline policies that you can embed in a group, see Limitations on IAM Entities in the IAM User Guide .

Methods

add_deletion_override(path)

Syntactic sugar for addOverride(path, undefined).

Parameters

path (str) – The path of the value to delete.

Return type

None

add_depends_on(target)

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.

Parameters

target (CfnResource) –

Return type

None

add_metadata(key, value)

Add a value to the CloudFormation Resource Metadata.

Parameters
  • key (str) –

  • value (Any) –

See

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.

Return type

None

add_override(path, 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:

cfn_resource.add_override("Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes", ["myattribute"])
cfn_resource.add_override("Properties.GlobalSecondaryIndexes.1.ProjectionType", "INCLUDE")

would add the overrides Example:

"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.

Parameters
  • path (str) –

    • The path of the property, you can use dot notation to override values in complex types. Any intermdediate keys will be created as needed.

  • value (Any) –

    • The value. Could be primitive or complex.

Return type

None

add_property_deletion_override(property_path)

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

Parameters

property_path (str) – The path to the property.

Return type

None

add_property_override(property_path, value)

Adds an override to a resource property.

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

Parameters
  • property_path (str) – The path of the property.

  • value (Any) – The value.

Return type

None

apply_removal_policy(policy=None, *, apply_to_update_replace_policy=None, default=None)

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).

Parameters
  • policy (Optional[RemovalPolicy]) –

  • apply_to_update_replace_policy (Optional[bool]) – Apply the same deletion policy to the resource’s “UpdateReplacePolicy”. Default: true

  • default (Optional[RemovalPolicy]) – The default policy to apply in case the removal policy is not defined. Default: - Default value is resource specific. To determine the default value for a resoure, please consult that specific resource’s documentation.

Return type

None

get_att(attribute_name)

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.

Parameters

attribute_name (str) – The name of the attribute.

Return type

Reference

get_metadata(key)

Retrieve a value value from the CloudFormation Resource Metadata.

Parameters

key (str) –

See

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.

Return type

Any

inspect(inspector)

Examines the CloudFormation resource and discloses attributes.

Parameters

inspector (TreeInspector) –

  • tree inspector to collect and process attributes.

Return type

None

override_logical_id(new_logical_id)

The name of the group to create. Do not include the path in this value.

The group name must be unique within the account. Group names are not distinguished by case. For example, you cannot create groups named both “ADMINS” and “admins”. If you don’t specify a name, AWS CloudFormation generates a unique physical ID and uses that ID for the group name. .. epigraph:

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 . .. epigraph:
