EventBridgeScheduler / Client / update_schedule

update_schedule#

EventBridgeScheduler.Client.update_schedule(**kwargs)#

Updates the specified schedule. When you call UpdateSchedule , EventBridge Scheduler uses all values, including empty values, specified in the request and overrides the existing schedule. This is by design. This means that if you do not set an optional field in your request, that field will be set to its system-default value after the update.

Before calling this operation, we recommend that you call the GetSchedule API operation and make a note of all optional parameters for your UpdateSchedule call.

Parameters:

ClientToken (string) –
Unique, case-sensitive identifier you provide to ensure the idempotency of the request. If you do not specify a client token, EventBridge Scheduler uses a randomly generated token for the request to ensure idempotency.

This field is autopopulated if not provided.
Description (string) – The description you specify for the schedule.
EndDate (datetime) – 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.
FlexibleTimeWindow (dict) –
[REQUIRED]

Allows you to configure a time window during which EventBridge Scheduler invokes the schedule.
- MaximumWindowInMinutes (integer) –
  
  The maximum time window during which a schedule can be invoked.
- Mode (string) – [REQUIRED]
  
  Determines whether the schedule is invoked within a flexible time window.
GroupName (string) – The name of the schedule group with which the schedule is associated. You must provide this value in order for EventBridge Scheduler to find the schedule you want to update. If you omit this value, EventBridge Scheduler assumes the group is associated to the default group.
KmsKeyArn (string) – The ARN for the customer managed KMS key that that you want EventBridge Scheduler to use to encrypt and decrypt your data.
Name (string) –
[REQUIRED]

The name of the schedule that you are updating.
ScheduleExpression (string) –
[REQUIRED]

The expression that defines when the schedule runs. The following formats are supported.
- at expression - at(yyyy-mm-ddThh:mm:ss)
- rate expression - rate(unit value)
- 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 .
ScheduleExpressionTimezone (string) – The timezone in which the scheduling expression is evaluated.
StartDate (datetime) – 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.
State (string) – Specifies whether the schedule is enabled or disabled.

  - LaunchType (string) –
    
    Specifies the launch type on which your task is running. The launch type that you specify here must match one of the launch type (compatibilities) of the target task.

    An array of placement constraint objects to use for the task. You can specify up to 10 constraints per task (including constraints in the task definition and those specified at runtime).
    - (dict) –
      
      An object representing a constraint on task placement.
      - expression (string) –
        
        A cluster query language expression to apply to the constraint. You cannot specify an expression if the constraint type is distinctInstance . For more information, see Cluster query language in the Amazon ECS Developer Guide .
      - type (string) –
        
        The type of constraint. Use distinctInstance to ensure that each task in a particular group is running on a different container instance. Use memberOf to restrict the selection to a group of valid candidates.
  - PlacementStrategy (list) –
    
    The task placement strategy for a task or service.
    - (dict) –
      
      The task placement strategy for a task or service.
      - field (string) –
        
        The field to apply the placement strategy against. For the spread placement strategy, valid values are instanceId (or instanceId , which has the same effect), or any platform or custom attribute that is applied to a container instance, such as attribute:ecs.availability-zone . For the binpack placement strategy, valid values are cpu and memory . For the random placement strategy, this field is not used.
      - type (string) –
        
        The type of placement strategy. The random placement strategy randomly places tasks on available candidates. The spread placement strategy spreads placement across available candidates evenly based on the field parameter. The binpack strategy places tasks on available candidates that have the least available amount of the resource that is specified with the field parameter. For example, if you binpack on memory, a task is placed on the instance with the least amount of remaining memory (but still enough to run the task).

    Specifies whether to propagate the tags from the task definition to the task. If no value is specified, the tags are not propagated. Tags can only be propagated to the task during task creation. To add tags to a task after task creation, use Amazon ECS’s TagResource API action.
  - ReferenceId (string) –
    
    The reference ID to use for the task.
  - Tags (list) –
    
    The metadata that you apply to the task to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define. For more information, see RunTask in the Amazon ECS API Reference .

  - Source (string) – [REQUIRED]
    
    The source of the event.
- Input (string) –
  
  The text, or well-formed JSON, passed to the target. If you are configuring a templated Lambda, AWS Step Functions, or Amazon EventBridge target, the input must be a well-formed JSON. For all other target types, a JSON is not required. If you do not specify anything for this field, EventBridge Scheduler delivers a default notification to the target.
