update-connectivity-info

Description

Updates connectivity information for a Greengrass core device.

Connectivity information includes endpoints and ports where client devices can connect to an MQTT broker on the core device. When a client device calls the IoT Greengrass discovery API , IoT Greengrass returns connectivity information for all of the core devices where the client device can connect. For more information, see Connect client devices to core devices in the IoT Greengrass Version 2 Developer Guide .

Options

--thing-name (string)

The name of the core device. This is also the name of the IoT thing.

--connectivity-info (list)

The connectivity information for the core device.

(structure)

Contains information about an endpoint and port where client devices can connect to an MQTT broker on a Greengrass core device.

id -> (string)

An ID for the connectivity information.

hostAddress -> (string)

The IP address or DNS address where client devices can connect to an MQTT broker on the Greengrass core device.

portNumber -> (integer)

The port where the MQTT broker operates on the core device. This port is typically 8883, which is the default port for the MQTT broker component that runs on core devices.

metadata -> (string)

Additional metadata to provide to client devices that connect to this core device.

Shorthand Syntax:

id=string,hostAddress=string,portNumber=integer,metadata=string ...

JSON Syntax:

[
  {
    "id": "string",
    "hostAddress": "string",
    "portNumber": integer,
    "metadata": "string"
  }
  ...
]

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To update connectivity information for a Greengrass core device

The following update-connectivity-info example gets the connectivity information for a Greengrass core device. Client devices use this information to connect to the MQTT broker that runs on this core device.

aws greengrassv2 update-connectivity-info \
    --thing-name MyGreengrassCore \
    --cli-input-json file://core-device-connectivity-info.json

Contents of core-device-connectivity-info.json:

{
    "connectivityInfo": [
        {
            "hostAddress": "192.0.2.0",
            "portNumber": 8883,
            "id": "localIP_192.0.2.0"
        }
    ]
}

Output:

{
    "version": "a1b2c3d4-5678-90ab-cdef-EXAMPLE11111"
}

For more information, see Manage core device endpoints in the AWS IoT Greengrass V2 Developer Guide.

Output

version -> (string)

The new version of the connectivity information for the core device.

message -> (string)

A message about the connectivity information update request.
