Put Scheduled Update Group Action

autoscaling_put_scheduled_update_group_action

R Documentation

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

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 describe_scheduled_actions API call. If you are no longer using a scheduled action, you can delete it by calling the delete_scheduled_action API.

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

Usage¶

autoscaling_put_scheduled_update_group_action(AutoScalingGroupName,
  ScheduledActionName, Time, StartTime, EndTime, Recurrence, MinSize,
  MaxSize, DesiredCapacity, TimeZone)

Arguments¶

AutoScalingGroupName

[required] The name of the Auto Scaling group.

ScheduledActionName

[required] The name of this scaling action.

Time

This property is no longer used.

StartTime

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.

EndTime

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

Recurrence

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.

MinSize

The minimum size of the Auto Scaling group.

MaxSize

The maximum size of the Auto Scaling group.

DesiredCapacity

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.

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

TimeZone

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.

Value¶

An empty list.
