set-instance-protection¶

Description¶

Updates the instance protection settings of the specified instances. This operation cannot be called on instances in a warm pool.

For more information about preventing instances that are part of an Auto Scaling group from terminating on scale in, see Using instance scale-in protection in the Amazon EC2 Auto Scaling User Guide .

If you exceed your maximum limit of instance IDs, which is 50 per Auto Scaling group, the call fails.

Synopsis¶

  set-instance-protection
--instance-ids <value>
--auto-scaling-group-name <value>
--protected-from-scale-in | --no-protected-from-scale-in
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--instance-ids (list)

One or more instance IDs. You can specify up to 50 instances.

(string)

Syntax:

"string" "string" ...

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

The name of the Auto Scaling group.

--protected-from-scale-in | --no-protected-from-scale-in (boolean)

Indicates whether the instance is protected from termination by Amazon EC2 Auto Scaling when scaling in.

--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.

See ‘aws help’ for descriptions of global parameters.

Examples¶

Example 1: To enable the instance protection setting for an instance

This example enables instance protection for the specified instance.

aws autoscaling set-instance-protection \
    --instance-ids i-061c63c5eb45f0416 \
    --auto-scaling-group-name my-asg --protected-from-scale-in

This command produces no output.

Example 2: To disable the instance protection setting for an instance

This example disables instance protection for the specified instance.

aws autoscaling set-instance-protection \
    --instance-ids i-061c63c5eb45f0416 \
    --auto-scaling-group-name my-asg \
    --no-protected-from-scale-in

This command produces no output.
