AWS::Greengrass::FunctionDefinitionCfnFunctionDefinition
The `AWS::Greengrass::FunctionDefinition` resource represents a function definition for AWS IoT Greengrass . Function definitions are used to organize your function definition versions. Function definitions can reference multiple function definition versions. All function definition versions must be associated with a function definition. Each function definition version can contain one or more functions. > When you create a function definition, you can optionally include an initial function definition version. To associate a function definition version later, create an [`AWS::Greengrass::FunctionDefinitionVersion`](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-greengrass-functiondefinitionversion.html) resource and specify the ID of this function definition. > > After you create the function definition version that contains the functions you want to deploy, you must add it to your group version. For more information, see [`AWS::Greengrass::Group`](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-greengrass-group.html) .
Import
import { CfnFunctionDefinition } from 'aws-cdk-lib/aws-greengrass';Or use the module namespace:
import * as greengrass from 'aws-cdk-lib/aws-greengrass';
// greengrass.CfnFunctionDefinitionProperties
Configuration passed to the constructor as CfnFunctionDefinitionProps.
nameRequiredstringThe name of the function definition.
initialVersionOptionalIResolvable | FunctionDefinitionVersionPropertyThe function definition version to include when the function definition is created. A function definition version contains a list of [`function`](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-greengrass-functiondefinition-function.html) property types. > To associate a function definition version after the function definition is created, create an [`AWS::Greengrass::FunctionDefinitionVersion`](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-greengrass-functiondefinitionversion.html) resource and specify the ID of this function definition.
tagsOptionalanyApplication-specific metadata to attach to the function definition. 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](https://docs.aws.amazon.com/greengrass/v1/developerguide/tagging.html) in the *Developer Guide* . This `Json` property type is processed as a map of key-value pairs. It uses the following format, which is different from most `Tags` implementations in CloudFormation templates. ```json "Tags": { "KeyName0": "value", "KeyName1": "value", "KeyName2": "value" } ```
CloudFormation Resource
This L1 construct maps directly to the following CloudFormation resource type.
