update-channel¶

Description¶

Used to update the settings of a channel.

Synopsis¶

  update-channel
--channel-name <value>
[--channel-storage <value>]
[--retention-period <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--channel-name (string)

The name of the channel to be updated.

--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. The retention period can’t be updated if the channel’s Amazon S3 storage is customer-managed.

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
}

--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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.

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 modify a channel

The following update-channel example modifies the settings for the specified channel.

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

Contents of update-channel.json:

{
    "channelName": "mychannel",
    "retentionPeriod": {
        "numberOfDays": 92
    }
}

This command produces no output.

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