To declare this entity in your AWS CloudFormation template, use the following syntax:

JSON

{
  "EndTime" : Timestamp,
  "ScalableTargetAction" : ScalableTargetAction,
  "Schedule" : String,
  "ScheduledActionName" : String,
  "StartTime" : Timestamp,
  "Timezone" : String
}

Properties

EndTime

The date and time that the action is scheduled to end, in UTC.

Required: No

Type: Timestamp

ScalableTargetAction

The new minimum and maximum capacity. You can set both values or just one. At the scheduled time, if the current capacity is below the minimum capacity, Application Auto Scaling scales out to the minimum capacity. If the current capacity is above the maximum capacity, Application Auto Scaling scales in to the maximum capacity.

Schedule

The schedule for this action. The following formats are supported:

  • At expressions - "at(yyyy-mm-ddThh:mm:ss)"

  • Rate expressions - "rate(value unit)"

  • Cron expressions - "cron(fields)"

At expressions are useful for one-time schedules. Cron expressions are useful for scheduled actions that run periodically at a specified date and time, and rate expressions are useful for scheduled actions that run at a regular interval.

At and cron expressions use Universal Coordinated Time (UTC) by default.

The cron format consists of six fields separated by white spaces: [Minutes] [Hours] [Day_of_Month] [Month] [Day_of_Week] [Year].

For rate expressions, value is a positive integer and unit is minute | minutes | hour | hours | day | days.

Required: Yes

Minimum: 1

Maximum: 1600
