[ aws . greengrass ]



Associates a role with a group. Your Greengrass core will use the role to access AWS cloud services. The role’s permissions should allow Greengrass core Lambda functions to perform actions against the cloud.

See ‘aws help’ for descriptions of global parameters.


--group-id <value>
--role-arn <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]


--group-id (string) The ID of the Greengrass group.

--role-arn (string) The ARN of the role you wish to associate with this group. The existence of the role is not validated.

--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.


To associate a role with a Greengrass group

The following associate-role-to-group example associates the specified IAM role with a Greengrass group. The group role is used by local Lambda functions and connectors to access AWS services. For example, your group role might grant permissions required for CloudWatch Logs integration.

aws greengrass associate-role-to-group \
    --group-id 2494ee3f-7f8a-4e92-a78b-d205f808b84b \
    --role-arn arn:aws:iam::123456789012:role/GG-Group-Role


    "AssociatedAt": "2019-09-10T20:03:30Z"

For more information, see Configure the Group Role in the AWS IoT Greengrass Developer Guide.


AssociatedAt -> (string)

The time, in milliseconds since the epoch, when the role ARN was associated with the group.
