tags (Optional[Sequence[Union[CfnTag, Dict[str, Any]]]]) – The tag key and value pairs that are attached to the resource group.

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:

Return type:

None

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.

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:

Return type:

Any

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.

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 logical ID for this CloudFormation stack element.

The logical ID of the element is calculated from the path of the resource node in the construct tree.

To override this value, use overrideLogicalId(newLogicalId).

Returns:

the logical ID as a stringified token. This value will only get resolved during synthesis.

name

The name of a resource group.

The name must be unique within the AWS Region in which you create the resource. To create multiple resource groups based on the same CloudFormation stack, you must generate unique names for each.

ResourceQueryProperty

class CfnGroup.ResourceQueryProperty(*, query=None, type=None)

Bases: object

The query used to dynamically define the members of a group.

For more information about how to construct a query, see Build queries and groups in AWS Resource Groups .

Parameters:

query (Union[IResolvable, QueryProperty, Dict[str, Any], None]) – The query that defines the membership of the group. This is a structure with properties that depend on the Type . The Query structure must be included in the following scenarios: - When the Type is TAG_FILTERS_1_0 , you must specify a Query structure that contains a TagFilters list of tags. Resources with tags that match those in the TagFilter list become members of the resource group. - When the Type is CLOUDFORMATION_STACK_1_0 then this field is required only when you must specify a CloudFormation stack other than the one you are defining. To do this, the Query structure must contain the StackIdentifier property. If you don’t specify either a Query structure or a StackIdentifier within that Query , then it defaults to the CloudFormation stack that you’re currently constructing.
type (Optional[str]) – Specifies the type of resource query that determines this group’s membership. There are two valid query types:. - TAG_FILTERS_1_0 indicates that the group is a tag-based group. To complete the group membership, you must include the TagFilters property to specify the tag filters to use in the query. - CLOUDFORMATION_STACK_1_0 , the default, indicates that the group is a CloudFormation stack-based group. Group membership is based on the CloudFormation stack. You must specify the StackIdentifier property in the query to define which stack to associate the group with, or leave it empty to default to the stack where the group is defined.

Attributes

query

The query that defines the membership of the group.

This is a structure with properties that depend on the Type .

The Query structure must be included in the following scenarios:

When the Type is TAG_FILTERS_1_0 , you must specify a Query structure that contains a TagFilters list of tags. Resources with tags that match those in the TagFilter list become members of the resource group.
When the Type is CLOUDFORMATION_STACK_1_0 then this field is required only when you must specify a CloudFormation stack other than the one you are defining. To do this, the Query structure must contain the StackIdentifier property. If you don’t specify either a Query structure or a StackIdentifier within that Query , then it defaults to the CloudFormation stack that you’re currently constructing.

Type:: Specifies the type of resource query that determines this group’s membership. There are two valid query types

TagFilterProperty

class CfnGroup.TagFilterProperty(*, key=None, values=None)

Bases: object

Specifies a single tag key and optional values that you can use to specify membership in a tag-based group.

An AWS resource that doesn’t have a matching tag key and value is rejected as a member of the group.

A TagFilter object includes two properties: Key (a string) and Values (a list of strings). Only resources in the account that are tagged with a matching key-value pair are members of the group. The Values property of TagFilter is optional, but specifying it narrows the query results.

As an example, suppose the TagFilters string is [{"Key": "Stage", "Values": ["Test", "Beta"]}, {"Key": "Storage"}] . In this case, only resources with all of the following tags are members of the group:

Stage tag key with a value of either Test or Beta
Storage tag key with any value

Parameters:

key (Optional[str]) – A string that defines a tag key. Only resources in the account that are tagged with a specified tag key are members of the tag-based resource group. This field is required when the ResourceQuery structure’s Type property is TAG_FILTERS_1_0 . You must specify at least one tag key.
values (Optional[Sequence[str]]) – A list of tag values that can be included in the tag-based resource group. This is optional. If you don’t specify a value or values for a key, then an AWS resource with any value for that key is a member.
