First time using the AWS CLI? See the User Guide for help getting started.

Note: You are viewing the documentation for an older major version of the AWS CLI (version 1).

AWS CLI version 2, the latest major version of AWS CLI, is now stable and recommended for general use. To view this page for the AWS CLI version 2, click here. For more information see the AWS CLI version 2 installation instructions and migration guide.

[ aws . iot ]



Gets an OTA update.

Requires permission to access the GetOTAUpdate action.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.


--ota-update-id <value>
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]


--ota-update-id (string)

The OTA update ID.

--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.

See 'aws help' for descriptions of global parameters.


To retrieve information about an OTA Update

The following get-ota-update example displays details about the specified OTA Update.

aws iot get-ota-update \
    --ota-update-id ota12345

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


otaUpdateInfo -> (structure)

The OTA update info.

otaUpdateId -> (string)

The OTA update ID.

otaUpdateArn -> (string)

The OTA update ARN.

creationDate -> (timestamp)

The date when the OTA update was created.

lastModifiedDate -> (timestamp)

The date when the OTA update was last updated.

description -> (string)

A description of the OTA update.

targets -> (list)

The targets of the OTA update.


protocols -> (list)

The protocol used to transfer the OTA update image. Valid values are [HTTP], [MQTT], [HTTP, MQTT]. When both HTTP and MQTT are specified, the target device can choose the protocol.


awsJobExecutionsRolloutConfig -> (structure)

Configuration for the rollout of OTA updates.

maximumPerMinute -> (integer)

The maximum number of OTA update job executions started per minute.

exponentialRate -> (structure)

The rate of increase for a job rollout. This parameter allows you to define an exponential rate increase for a job rollout.

baseRatePerMinute -> (integer)

The minimum number of things that will be notified of a pending job, per minute, at the start of the job rollout. This is the initial rate of the rollout.

incrementFactor -> (double)

The rate of increase for a job rollout. The number of things notified is multiplied by this factor.

rateIncreaseCriteria -> (structure)

The criteria to initiate the increase in rate of rollout for a job.

Amazon Web Services IoT Core supports up to one digit after the decimal (for example, 1.5, but not 1.55).

numberOfNotifiedThings -> (integer)

When this number of things have been notified, it will initiate an increase in the rollout rate.

numberOfSucceededThings -> (integer)

When this number of things have succeeded in their job execution, it will initiate an increase in the rollout rate.

awsJobPresignedUrlConfig -> (structure)

Configuration information for pre-signed URLs. Valid when protocols contains HTTP.

expiresInSec -> (long)

How long (in seconds) pre-signed URLs are valid. Valid values are 60 - 3600, the default value is 1800 seconds. Pre-signed URLs are generated when a request for the job document is received.

targetSelection -> (string)

Specifies whether the OTA update will continue to run (CONTINUOUS), or will be complete after all those things specified as targets have completed the OTA update (SNAPSHOT). If continuous, the OTA update may also be run on a thing when a change is detected in a target. For example, an OTA update will run on a thing when the thing is added to a target group, even after the OTA update was completed by all things originally in the group.
