create-resource-definition¶

Description¶

Creates a resource definition which contains a list of resources to be used in a group. You can create an initial version of the definition by providing a list of resources now, or use ‘’CreateResourceDefinitionVersion’’ later.

--initial-version (structure) Information about the initial version of the resource definition.Resources -> (list)

A list of resources.

(structure)

Information about a resource.

Id -> (string)

The resource ID, used to refer to a resource in the Lambda function configuration. Max length is 128 characters with pattern ‘’[a-zA-Z0-9:_-]+’’. This must be unique within a Greengrass group.

Name -> (string)

The descriptive resource name, which is displayed on the AWS IoT Greengrass console. Max length 128 characters with pattern ‘’[a-zA-Z0-9:_-]+’’. This must be unique within a Greengrass group.

Group/owner related settings for local resources.

AutoAddGroupOwner -> (boolean)

If true, AWS IoT Greengrass automatically adds the specified Linux OS group owner of the resource to the Lambda process privileges. Thus the Lambda process will have the file access permissions of the added Linux group.

GroupOwner -> (string)

The name of the Linux OS group whose privileges will be added to the Lambda process. This field is optional.

The absolute local path of the resource inside the Lambda environment.

OwnerSetting -> (structure)

The owner setting for downloaded machine learning resources.

GroupOwner -> (string)

The group owner of the resource. This is the name of an existing Linux OS group on the system or a GID. The group’s permissions are added to the Lambda process.

GroupPermission -> (string)

The permissions that the group owner has to the resource. Valid values are ‘’rw’’ (read/write) or ‘’ro’’ (read-only).

SageMakerJobArn -> (string)

The ARN of the Amazon SageMaker training job that represents the source model.

SecretsManagerSecretResourceData -> (structure)

Attributes that define a secret resource, which references a secret from AWS Secrets Manager.

ARN -> (string)

The ARN of the Secrets Manager secret to make available on the core. The value of the secret’s latest version (represented by the ‘’AWSCURRENT’’ staging label) is included by default.

AdditionalStagingLabelsToDownload -> (list)

Optional. The staging labels whose values you want to make available on the core, in addition to ‘’AWSCURRENT’’.

--name (string) The name of the resource definition.

Shorthand Syntax:

JSON Syntax:

{"string": "string"

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Examples¶

To create a resource definition

The following create-resource-definition example creates a resource definition that contains a list of resources to be used in a Greengrass group. In this example, an initial version of the resource definition is included by providing a list of resources. The list includes one resource for a Twilio authorization token and the ARN for a secret stored in AWS Secrets Manager. You must create the secret before you can create the resource definition.

aws greengrass create-resource-definition \
    --name MyGreengrassResources \
    --initial-version "{\"Resources\": [{\"Id\": \"TwilioAuthToken\",\"Name\": \"MyTwilioAuthToken\",\"ResourceDataContainer\": {\"SecretsManagerSecretResourceData\": {\"ARN\": \"arn:aws:secretsmanager:us-west-2:123456789012:secret:greengrass-TwilioAuthToken-ntSlp6\"}}}]}"

Output:

{
    "Arn": "arn:aws:greengrass:us-west-2:123456789012:/greengrass/definition/resources/c8bb9ebc-c3fd-40a4-9c6a-568d75569d38",
    "CreationTimestamp": "2019-06-19T21:51:28.212Z",
    "Id": "c8bb9ebc-c3fd-40a4-9c6a-568d75569d38",
    "LastUpdatedTimestamp": "2019-06-19T21:51:28.212Z",
    "LatestVersion": "a5f94d0b-f6bc-40f4-bb78-7a1c5fe13ba1",
    "LatestVersionArn": "arn:aws:greengrass:us-west-2:123456789012:/greengrass/definition/resources/c8bb9ebc-c3fd-40a4-9c6a-568d75569d38/versions/a5f94d0b-f6bc-40f4-bb78-7a1c5fe13ba1",
    "Name": "MyGreengrassResources"
}
