put-scheduled-update-group-action

Description

Creates or updates a scheduled scaling action for an Auto Scaling group.

For more information, see Scheduled scaling in the Amazon EC2 Auto Scaling User Guide .

You can view the scheduled actions for an Auto Scaling group using the DescribeScheduledActions API call. If you are no longer using a scheduled action, you can delete it by calling the DeleteScheduledAction API.

If you try to schedule your action in the past, Amazon EC2 Auto Scaling returns an error message.

Options

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

The name of the Auto Scaling group.

--scheduled-action-name (string)

The name of this scaling action.

--time (timestamp)

This property is no longer used.

--start-time (timestamp)

The date and time for this action to start, in YYYY-MM-DDThh:mm:ssZ format in UTC/GMT only and in quotes (for example, "2021-06-01T00:00:00Z" ).

If you specify Recurrence and StartTime , Amazon EC2 Auto Scaling performs the action at this time, and then performs the action based on the specified recurrence.

--end-time (timestamp)

The date and time for the recurring schedule to end, in UTC. For example, "2021-06-01T00:00:00Z" .

--recurrence (string)

The recurring schedule for this action. This format consists of five fields separated by white spaces: [Minute] [Hour] [Day_of_Month] [Month_of_Year] [Day_of_Week]. The value must be in quotes (for example, "30 0 1 1,6,12 *" ). For more information about this format, see Crontab .

When StartTime and EndTime are specified with Recurrence , they form the boundaries of when the recurring action starts and stops.

Cron expressions use Universal Coordinated Time (UTC) by default.

--min-size (integer)

The minimum size of the Auto Scaling group.

--max-size (integer)

The maximum size of the Auto Scaling group.

--desired-capacity (integer)

The desired capacity is the initial capacity of the Auto Scaling group after the scheduled action runs and the capacity it attempts to maintain. It can scale beyond this capacity if you add more scaling conditions.

Note

You must specify at least one of the following properties: MaxSize , MinSize , or DesiredCapacity .

--time-zone (string)

Specifies the time zone for a cron expression. If a time zone is not provided, UTC is used by default.

Valid values are the canonical names of the IANA time zones, derived from the IANA Time Zone Database (such as Etc/GMT+9 or Pacific/Tahiti ). For more information, see https://en.wikipedia.org/wiki/List_of_tz_database_time_zones .

--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 .

Example 1: To add a scheduled action to an Auto Scaling group

This example adds the specified scheduled action to the specified Auto Scaling group.

aws autoscaling put-scheduled-update-group-action \
    --auto-scaling-group-name my-asg \
    --scheduled-action-name my-scheduled-action \
    --start-time "2021-05-12T08:00:00Z" \
    --min-size 2 \
    --max-size 6 \
    --desired-capacity 4

This command produces no output. If a scheduled action with the same name already exists, it will be overwritten by the new scheduled action.

For more examples, see Scheduled scaling in the Amazon EC2 Auto Scaling User Guide.

Example 2: To specify a recurring schedule

This example creates a scheduled action to scale on a recurring schedule that is scheduled to execute at 00:30 hours on the first of January, June, and December every year.

aws autoscaling put-scheduled-update-group-action \
    --auto-scaling-group-name my-asg \
    --scheduled-action-name my-recurring-action \
    --recurrence "30 0 1 1,6,12 *" \
    --min-size 2 \
    --max-size 6 \
    --desired-capacity 4

This command produces no output. If a scheduled action with the same name already exists, it will be overwritten by the new scheduled action.

For more examples, see Scheduled scaling in the Amazon EC2 Auto Scaling User Guide.
