AWS::Greengrass::ConnectorDefinition

The AWS::Greengrass::ConnectorDefinition resource represents a connector definition for Amazon IoT Greengrass. Connector definitions are used to organize your connector definition versions.

Connector definitions can reference multiple connector definition versions. All connector definition versions must be associated with a connector definition. Each connector definition version can contain one or more connectors.

Note

When you create a connector definition, you can optionally include an initial connector definition version. To associate a connector definition version later, create an AWS::Greengrass::ConnectorDefinitionVersion resource and specify the ID of this connector definition.

After you create the connector definition version that contains the connectors you want to deploy, you must add it to your group version. For more information, see AWS::Greengrass::Group.

Syntax

To declare this entity in your Amazon CloudFormation template, use the following syntax:

JSON


{
  "Type" : "AWS::Greengrass::ConnectorDefinition",
  "Properties" : {
      "InitialVersion" : ConnectorDefinitionVersion,
      "Name" : String,
      "Tags" : Json
    }
}

YAML


Type: AWS::Greengrass::ConnectorDefinition
Properties: 
  InitialVersion: 
    ConnectorDefinitionVersion
  Name: String
  Tags: Json

Properties

InitialVersion

The connector definition version to include when the connector definition is created. A connector definition version contains a list of connector property types.

Note

To associate a connector definition version after the connector definition is created, create an AWS::Greengrass::ConnectorDefinitionVersion resource and specify the ID of this connector definition.

Required: No

Type: ConnectorDefinitionVersion

Update requires: Replacement

Name

The name of the connector definition.

Required: Yes

Type: String

Update requires: No interruption

Tags

Application-specific metadata to attach to the connector definition. You can use tags in IAM policies to control access to Amazon IoT Greengrass resources. You can also use tags to categorize your resources. For more information, see Tagging Your Amazon IoT Greengrass Resources in the Amazon IoT Greengrass Version 1 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 Amazon CloudFormation templates.


"Tags": {
    "KeyName0": "value",
    "KeyName1": "value",
    "KeyName2": "value"
}

Required: No

Type: Json

Update requires: No interruption

Return values

Ref

When you pass the logical ID of this resource to the intrinsic Reffunction, Refreturns the ID of the connector definition, such as 1234a5b6-78cd-901e-2fgh-3i45j6k178l9.

For more information about using the Reffunction, see Ref.

Fn::GetAtt

The Fn::GetAttintrinsic function returns a value for a specified attribute of this type. The following are the available attributes and sample return values.

For more information about using the Fn::GetAttintrinsic function, see Fn::GetAtt.

Arn: The Amazon Resource Name (ARN) of the ConnectorDefinition, such as arn:aws:greengrass:us-east-1:123456789012:/greengrass/definition/connectors/1234a5b6-78cd-901e-2fgh-3i45j6k178l9.
Id: The ID of the ConnectorDefinition, such as 1234a5b6-78cd-901e-2fgh-3i45j6k178l9.
LatestVersionArn: The ARN of the last ConnectorDefinitionVersion that was added to the ConnectorDefinition, such as arn:aws:greengrass:us-east-1:123456789012:/greengrass/definition/connectors/1234a5b6-78cd-901e-2fgh-3i45j6k178l9/versions/9876ac30-4bdb-4f9d-95af-b5fdb66be1a2.
Name: The name of the ConnectorDefinition, such as MyConnectorDefinition.
