Operation

create_instance_event_window async

create_instance_event_window(input: CreateInstanceEventWindowInput, plugins: list[Plugin] | None = None) -> CreateInstanceEventWindowOutput

Creates an event window in which scheduled events for the associated Amazon EC2 instances can run.

You can define either a set of time ranges or a cron expression when creating the event window, but not both. All event window times are in UTC.

You can create up to 200 event windows per Amazon Web Services Region.

When you create the event window, targets (instance IDs, Dedicated Host IDs, or tags) are not yet associated with it. To ensure that the event window can be used, you must associate one or more targets with it by using the AssociateInstanceEventWindow API.

Warning

Event windows are applicable only for scheduled events that stop, reboot, or terminate instances.

Event windows are not applicable for:

  • Expedited scheduled events and network maintenance events.

  • Unscheduled maintenance such as AutoRecovery and unplanned reboots.

For more information, see Define event windows for scheduled events in the Amazon EC2 User Guide.

Parameters:

Name Type Description Default
input CreateInstanceEventWindowInput

An instance of CreateInstanceEventWindowInput.

required
plugins list[Plugin] | None

A list of callables that modify the configuration dynamically. Changes made by these plugins only apply for the duration of the operation execution and will not affect any other operation invocations.

None

Returns:

Type Description
CreateInstanceEventWindowOutput

An instance of CreateInstanceEventWindowOutput.

Input

CreateInstanceEventWindowInput dataclass

Bases: _SerdeShape

Dataclass for CreateInstanceEventWindowInput structure.

Attributes

cron_expression class-attribute instance-attribute
cron_expression: str | None = ...

The cron expression for the event window, for example, * 0-4,20-23 * * 1,5. If you specify a cron expression, you can't specify a time range.

Constraints:

  • Only hour and day of the week values are supported.

  • For day of the week values, you can specify either integers 0 through 6, or alternative single values SUN through SAT.

  • The minute, month, and year must be specified by *.

  • The hour value must be one or a multiple range, for example, 0-4 or 0-4,20-23.

  • Each hour range must be >= 2 hours, for example, 0-2 or 20-23.

  • The event window must be >= 4 hours. The combined total time ranges in the event window must be >= 4 hours.

For more information about cron expressions, see cron on the Wikipedia website.

dry_run class-attribute instance-attribute
dry_run: bool | None = ...

Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

name class-attribute instance-attribute
name: str | None = ...

The name of the event window.

tag_specifications class-attribute instance-attribute
tag_specifications: list[TagSpecification] | None = ...

The tags to apply to the event window.

time_ranges: list[InstanceEventWindowTimeRangeRequest] | None = ...

The time range for the event window. If you specify a time range, you can't specify a cron expression.

Output

CreateInstanceEventWindowOutput dataclass

Bases: _SerdeShape

Dataclass for CreateInstanceEventWindowOutput structure.

Attributes

instance_event_window class-attribute instance-attribute
instance_event_window: InstanceEventWindow | None = ...

Information about the event window.

response_metadata class-attribute instance-attribute
response_metadata: ResponseMetadata = ...

Metadata about the response that produced this output. Use this to recover the request identifiers a service's support team needs in order to investigate a call. Members of the metadata are individually optional.
