Properties

EndTime

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

Required: No

ScalableTargetAction

The new minimum and maximum capacity. You can set both values or just one.

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.
