  source  = "endre-synnes/aws-sqs-with-dlq-and-cloudwatch-alarm"
  version = "~> 0.0.3"
  
  queue_name                      = "my-queue"
  dead_letter_queue_name          = "my-dead-letter-queue"
  cloudwatch_alarm_name           = "my-cloudwatch-alarm"
  cloudwatch_alarm_sns_topic_arn  = "my-sns-topic"
}
