Options

--channel-name (string)

The name of the channel.

--channel-storage (structure)

Where channel data is stored. You can choose one of serviceManagedS3 or customerManagedS3 storage. If not specified, the default is serviceManagedS3 . You can't change this storage option after the channel is created.

serviceManagedS3 -> (structure)

Used to store channel data in an S3 bucket managed by IoT Analytics. You can't change the choice of S3 storage after the data store is created.

customerManagedS3 -> (structure)

Used to store channel data in an S3 bucket that you manage. If customer managed storage is selected, the retentionPeriod parameter is ignored. You can't change the choice of S3 storage after the data store is created.

bucket -> (string)

The name of the S3 bucket in which channel data is stored.

keyPrefix -> (string)

(Optional) The prefix used to create the keys of the channel data objects. Each object in an S3 bucket has a key that is its unique identifier in the bucket. Each object in a bucket has exactly one key. The prefix must end with a forward slash (/).

roleArn -> (string)

The ARN of the role that grants IoT Analytics permission to interact with your Amazon S3 resources.

Shorthand Syntax:

serviceManagedS3={},customerManagedS3={bucket=string,keyPrefix=string,roleArn=string}

JSON Syntax:

{
  "serviceManagedS3": {

  },
  "customerManagedS3": {
    "bucket": "string",
    "keyPrefix": "string",
    "roleArn": "string"
  }
}

--retention-period (structure)

How long, in days, message data is kept for the channel. When customerManagedS3 storage is selected, this parameter is ignored.

unlimited -> (boolean)

If true, message data is kept indefinitely.

numberOfDays -> (integer)

The number of days that message data is kept. The unlimited parameter must be false.

Shorthand Syntax:

unlimited=boolean,numberOfDays=integer

JSON Syntax:

{
  "unlimited": true|false,
  "numberOfDays": integer
}

--tags (list)

Metadata which can be used to manage the channel.

(structure)

A set of key-value pairs that are used to manage the resource.

key -> (string)

The tag's key.

value -> (string)

The tag's value.

Shorthand Syntax:

key=string,value=string ...

JSON Syntax:

[
  {
    "key": "string",
    "value": "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 create a channel

The following create-channel example creates a channel with the specified configuration. A channel collects data from an MQTT topic and archives the raw, unprocessed messages before publishing the data to a pipeline.

aws iotanalytics create-channel \
    --cli-input-json file://create-channel.json

Contents of create-channel.json:

{
    "channelName": "mychannel",
    "retentionPeriod": {
        "unlimited": true
    },
    "tags": [
        {
            "key": "Environment",
            "value": "Production"
        }
    ]
}

Output:

{
    "channelArn": "arn:aws:iotanalytics:us-west-2:123456789012:channel/mychannel",
    "channelName": "mychannel",
    "retentionPeriod": {
        "unlimited": true
    }
}

For more information, see CreateChannel in the AWS IoT Analytics API Reference.
