EventBridge Scheduler
aws
AWS: aws_scheduler_schedule
Provides an EventBridge Scheduler Schedule resource.

Resource: aws_scheduler_schedule

Provides an EventBridge Scheduler Schedule resource.

You can find out more about EventBridge Scheduler in the User Guide.

~> Note: EventBridge was formerly known as CloudWatch Events. The functionality is identical.

Example Usage

Basic Usage

resource "aws_scheduler_schedule" "example" {
  name       = "my-schedule"
  group_name = "default"

  flexible_time_window {
    mode = "OFF"
  }

  schedule_expression = "rate(1 hour)"

  target {
    arn      = aws_sqs_queue.example.arn
    role_arn = aws_iam_role.example.arn
  }
}

Universal Target

resource "aws_sqs_queue" "example" {}

resource "aws_scheduler_schedule" "example" {
  name = "my-schedule"

  flexible_time_window {
    mode = "OFF"
  }

  schedule_expression = "rate(1 hour)"

  target {
    arn      = "arn:aws:scheduler:::aws-sdk:sqs:sendMessage"
    role_arn = aws_iam_role.example.arn

    input = jsonencode({
      MessageBody = "Greetings, programs!"
      QueueUrl    = aws_sqs_queue.example.url
    })
  }
}

Argument Reference

The following arguments are required:

  • flexible_time_window - (Required) Configures a time window during which EventBridge Scheduler invokes the schedule. Detailed below.
  • schedule_expression - (Required) Defines when the schedule runs. Read more in Schedule types on EventBridge Scheduler.
  • target - (Required) Configures the target of the schedule. Detailed below.

The following arguments are optional:

  • description - (Optional) Brief description of the schedule.
  • end_date - (Optional) 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 end date you specify. EventBridge Scheduler ignores the end date for one-time schedules. Example: 2030-01-01T01:00:00Z.
  • group_name - (Optional, Forces new resource) Name of the schedule group to associate with this schedule. When omitted, the default schedule group is used.
  • kms_key_arn - (Optional) ARN for the customer managed KMS key that EventBridge Scheduler will use to encrypt and decrypt your data.
  • name - (Optional, Forces new resource) Name of the schedule. If omitted, Terraform will assign a random, unique name. Conflicts with name_prefix.
  • name_prefix - (Optional, Forces new resource) Creates a unique name beginning with the specified prefix. Conflicts with name.
  • schedule_expression_timezone - (Optional) Timezone in which the scheduling expression is evaluated. Defaults to UTC. Example: Australia/Sydney.
  • start_date - (Optional) 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 start date you specify. EventBridge Scheduler ignores the start date for one-time schedules. Example: 2030-01-01T01:00:00Z.
  • state - (Optional) Specifies whether the schedule is enabled or disabled. One of: ENABLED (default), DISABLED.

target Configuration Block

The following arguments are required:

The following arguments are optional:

  • retry_policy - (Optional) Information about the retry policy settings. Detailed below.
  • sagemaker_pipeline_parameters - (Optional) Templated target type for the Amazon SageMaker StartPipelineExecution API operation. Detailed below.
  • sqs_parameters - (Optional) The templated target type for the Amazon SQS SendMessage API operation. Detailed below.
