AWS::Scheduler::Schedule

A schedule is the main resource you create, configure, and manage using Amazon EventBridge Scheduler.

Every schedule has a schedule expression that determines when, and with what frequency, the schedule runs. EventBridge Scheduler supports three types of schedules: rate, cron, and one-time schedules. For more information about different schedule types, see Schedule types in the EventBridge Scheduler User Guide.

When you create a schedule, you configure a target for the schedule to invoke. A target is an API operation that EventBridge Scheduler calls on your behalf every time your schedule runs. EventBridge Scheduler supports two types of targets: templated targets invoke common API operations across a core groups of services, and customizeable universal targets that you can use to call more than 6,000 operations across over 270 services. For more information about configuring targets, see Managing targets in the EventBridge Scheduler User Guide.

For more information about managing schedules, changing the schedule state, setting up flexible time windows, and configuring a dead-letter queue for a schedule, see Managing a schedule in the EventBridge Scheduler User Guide.

Properties

Description

The description you specify for the schedule.

Required: No

Type: String

Minimum: 0

Maximum: 512

Update requires: No interruption

EndDate

The date, in UTC, before which the schedule can invoke its target. Depending on the schedule's recurrence expression, invocations might stop on, or before, the EndDate you specify. EventBridge Scheduler ignores EndDate for one-time schedules.

Required: No

Type: String

Update requires: No interruption

FlexibleTimeWindow

Allows you to configure a time window during which EventBridge Scheduler invokes the schedule.

Required: Yes

Type: FlexibleTimeWindow

Update requires: No interruption

GroupName

The name of the schedule group associated with this schedule.

Required: No

Type: String

Pattern: ^[0-9a-zA-Z-_.]+$

Minimum: 1

Maximum: 64

Update requires: No interruption

KmsKeyArn

The Amazon Resource Name (ARN) for the customer managed KMS key that EventBridge Scheduler will use to encrypt and decrypt your data.

Required: No

Type: String

Pattern: ^arn:aws[a-z-]*:kms:[a-z0-9\-]+:\d{12}:(key|alias)\/[0-9a-zA-Z-_]*$

Minimum: 1

Maximum: 2048

Update requires: No interruption

Name

The name of the schedule.

Required: No

Type: String

Pattern: ^[0-9a-zA-Z-_.]+$

Minimum: 1

Maximum: 64

Update requires: Replacement

ScheduleExpression

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

For more information and examples, see Schedule types on EventBridge Scheduler in the EventBridge Scheduler User Guide.

Required: Yes

Type: String

Minimum: 1

Maximum: 256

Update requires: No interruption

ScheduleExpressionTimezone

The timezone in which the scheduling expression is evaluated.

Required: No

Type: String

Minimum: 1

Maximum: 50

Update requires: No interruption

StartDate

The date, in UTC, after which the schedule can begin invoking its target. Depending on the schedule's recurrence expression, invocations might occur on, or after, the StartDate you specify. EventBridge Scheduler ignores StartDate for one-time schedules.

Return values

Ref

When you pass the logical ID of this resource to the intrinsic Ref function, Ref returns the Name attribute of theschedule.

Fn::GetAtt

The Fn::GetAtt intrinsic function returns a value for a specified attribute of this type. The following are the available attributes that Fn::GetAtt returns. For more information about using the Fn::GetAtt intrinsic function, see Fn::GetAtt.
