[ aws . autoscaling ]



Moves the specified instances out of the standby state.

After you put the instances back in service, the desired capacity is incremented.

For more information, see Temporarily Removing Instances from Your Auto Scaling Group in the Amazon EC2 Auto Scaling User Guide .

See ‘aws help’ for descriptions of global parameters.


[--instance-ids <value>]
--auto-scaling-group-name <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]


--instance-ids (list)

The IDs of the instances. You can specify up to 20 instances.



"string" "string" ...

--auto-scaling-group-name (string)

The name of the Auto Scaling group.

--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.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.


To move instances out of standby mode

This example moves the specified instance out of standby mode:

aws autoscaling exit-standby --instance-ids i-93633f9b --auto-scaling-group-name my-auto-scaling-group

The following is example output:

            "Description": "Moving EC2 instance out of Standby: i-93633f9b",
