# aws\_autoscaling\_schedule
|
||||
|
||||
Provides an AutoScaling Schedule resource.
|
||||
|
||||
## Example Usage
|
||||
```
|
||||
resource "aws_autoscaling_group" "foobar" {
|
||||
availability_zones = ["us-west-2a"]
|
||||
name = "terraform-test-foobar5"

|
||||

|
||||
}
|
||||
|
||||
resource "aws_autoscaling_schedule" "foobar" {
|
||||
scheduled_action_name = "foobar"
|
||||
min_size = 0
|
||||
max_size = 1
|
||||
desired_capacity = 0
|
||||
start_time = "2016-12-11T18:00:00Z"
|
||||
end_time = "2016-12-12T06:00:00Z"
|
||||
autoscaling_group_name = "${aws_autoscaling_group.foobar.name}"
|
||||
}
|
||||
```
|
||||
|
||||
## Argument Reference
|
||||
|
||||
The following arguments are supported:
|
||||
|
||||
* `autoscaling_group_name` - (Required) The name or Amazon Resource Name (ARN) of the Auto Scaling group.
|
||||
* `scheduled_action_name` - (Required) The name of this scaling action.
|
||||
* `start_time` - (Optional) The time for this action to start, in "YYYY-MM-DDThh:mm:ssZ" format in UTC/GMT only (for example, 2014-06-01T00:00:00Z ).
|
||||
If you try to schedule your action in the past, Auto Scaling returns an error message.
|
||||
* `end_time` - (Optional) The time for this action to end, in "YYYY-MM-DDThh:mm:ssZ" format in UTC/GMT only (for example, 2014-06-01T00:00:00Z ).
|
||||
If you try to schedule your action in the past, Auto Scaling returns an error messag
|
||||
* `recurrence` - (Optional) The time when recurring future actions will start. Start time is specified by the user following the Unix cron syntax format.
|
||||
* `min_size` - (Optional) The minimum size for the Auto Scaling group.
|
||||
* `max_size` - (Optional) The maximum size for the Auto Scaling group.
|
||||
* `desired_capacity` - (Optional) The number of EC2 instances that should be running in the group.
|
||||
|
||||
~> **NOTE:** When `start_time` and `end_time` are specified with `recurrence` , they form the boundaries of when the recurring action will start and stop.
|
||||
|
||||
## Attribute Reference
|
||||
* `arn` - The ARN assigned by AWS to the autoscaling schedule.
