Method: Aws::Scheduler::Types::UpdateScheduleInput#schedule_expression

Defined in:

lib/aws-sdk-scheduler/types.rb

#schedule_expression ⇒ String

The expression that defines when the schedule runs. The following formats are supported.

• ‘at` expression - `at(yyyy-mm-ddThh:mm:ss)`

• ‘rate` expression - `rate(value unit)`

• ‘cron` expression - `cron(fields)`

You can use ‘at` expressions to create one-time schedules that invoke a target once, at the time and in the time zone, that you specify. You can use `rate` and `cron` expressions to create recurring schedules. Rate-based schedules are useful when you want to invoke a target at regular intervals, such as every 15 minutes or every five days. Cron-based schedules are useful when you want to invoke a target periodically at a specific time, such as at 8:00 am (UTC+0) every 1st day of the month.

A ‘cron` expression consists of six fields separated by white spaces: `(minutes hours day_of_month month day_of_week year)`.

A ‘rate` expression consists of a value as a positive integer, and a unit with the following options: `minute` | `minutes` | `hour` | `hours` | `day` | `days`
