AWS::Greengrass::Group
.AWS IoT Greengrass seamlessly extends AWS to edge devices so they can act locally on the data they generate, while still using the cloud for management, analytics, and durable storage. With AWS IoT Greengrass , connected devices can run AWS Lambda functions, execute predictions based on machine learning models, keep device data in sync, and communicate with other devices securely – even when not connected to the internet. For more information, see the Developer Guide . .. epigraph:
For AWS Region support, see `AWS CloudFormation Support for AWS IoT Greengrass <https://docs.aws.amazon.com/greengrass/latest/developerguide/cloudformation-support.html>`_ in the *Developer Guide* .
The
AWS::Greengrass::Group
resource represents a group in AWS IoT Greengrass . In the AWS IoT Greengrass API, groups are used to organize your group versions.Groups can reference multiple group versions. All group versions must be associated with a group. A group version references a device definition version, subscription definition version, and other version types that contain the components you want to deploy to a Greengrass core device.
To deploy a group version, the group version must reference a core definition version that contains one core. Other version types are optionally included, depending on your business need. .. epigraph:
When you create a group, you can optionally include an initial group version. To associate a group version later, create a ```AWS::Greengrass::GroupVersion`` <https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-greengrass-groupversion.html>`_ resource and specify the ID of this group. To change group components (such as devices, subscriptions, or functions), you must create new versions. This is because versions are immutable. For example, to add a function, you create a function definition version that contains the new function (and all other functions that you want to deploy). Then you create a group version that references the new function definition version (and all other version types that you want to deploy).
Deploying a Group Version
After you create the group version in your AWS CloudFormation template, you can deploy it using the
`aws greengrass create-deployment
<https://docs.aws.amazon.com/greengrass/latest/apireference/createdeployment-post.html>`_ command in the AWS CLI or from the Greengrass node in the AWS IoT console. To deploy a group version, you must have a Greengrass service role associated with your AWS account .

Create a new
AWS::Greengrass::Group
.- Parameters:
scope (
Construct
) –scope in which this resource is defined.
id (
str
) –scoped id of the resource.
name (
str
) – The name of the group.initial_version (
Union
[IResolvable
,GroupVersionProperty
,Dict
[str
,Any
],None
]) – The group version to include when the group is created. A group version references the Amazon Resource Name (ARN) of a core definition version, device definition version, subscription definition version, and other version types. The group version must reference a core definition version that contains one core. Other version types are optionally included, depending on your business need. .. epigraph:: To associate a group version after the group is created, create an`AWS::Greengrass::GroupVersion
<https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-greengrass-groupversion.html>`_ resource and specify the ID of this group.role_arn (
Optional
[str
]) – The Amazon Resource Name (ARN) of the IAM role attached to the group. This role contains the permissions that Lambda functions and connectors use to interact with other AWS services.tags (
Optional
[Any
]) – Application-specific metadata to attach to the group. You can use tags in IAM policies to control access to AWS IoT Greengrass resources. You can also use tags to categorize your resources. For more information, see Tagging Your AWS IoT Greengrass Resources in the Developer Guide . ThisJson
property type is processed as a map of key-value pairs. It uses the following format, which is different from mostTags
implementations in AWS CloudFormation templates:: “Tags”: { “KeyName0”: “value”, “KeyName1”: “value”, “KeyName2”: “value” }
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
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 prefixpath
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 toaddOverride
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: truedefault (
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:
- get_metadata(key)
Retrieve a value value from the CloudFormation Resource Metadata.
- Parameters:
key (
str
)- See:
- Return type:
Any
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)

- Parameters:
new_logical_id (
str
) – The new logical ID to use for this stack element.- Return type:
None
- to_string()
Returns a string representation of this construct.
- Return type:
str
- Returns:
a string representation of this resource
