创建数据管道的Terraform

要创建数据管道的 Terraform，您可以使用 AWS Data Pipeline 服务。以下是一个使用 Terraform 创建 AWS 数据管道的示例代码：

provider "aws" {
  region = "us-west-2"
}

resource "aws_data_pipeline_pipeline" "example" {
  name        = "example_pipeline"
  description = "Example data pipeline"

  unique_id = "example_pipeline"

  tags = {
    environment = "dev"
  }

  activate {
    schedule_expression = "cron(0 0 * * ? *)"
  }

  parameter_objects {
    id   = "s3InputLocation"
    key  = "type"
    string_value = "S3DataNode"
  }

  parameter_objects {
    id   = "s3OutputLocation"
    key  = "type"
    string_value = "S3DataNode"
  }

  parameter_values {
    id   = "s3InputLocation"
    string_value = "s3://input-bucket/"
  }

  parameter_values {
    id   = "s3OutputLocation"
    string_value = "s3://output-bucket/"
  }

  pipeline_objects {
    id   = "s3InputLocation"
    name = "s3_input"
    type = "S3DataNode"
    fields {
      key = "directoryPath"
      string_value = "input/"
    }
  }

  pipeline_objects {
    id   = "s3OutputLocation"
    name = "s3_output"
    type = "S3DataNode"
    fields {
      key = "directoryPath"
      string_value = "output/"
    }
  }

  pipeline_objects {
    id   = "copyActivity"
    name = "copy_activity"
    type = "CopyActivity"
    fields {
      key = "input"
      ref_value = "s3_input"
    }
    fields {
      key = "output"
      ref_value = "s3_output"
    }
    fields {
      key = "runsOn"
      string_value = "Ec2Resource"
    }
    fields {
      key = "script"
      string_value = "command-to-copy-data"
    }
  }
}

上面的代码创建了一个名为 "example_pipeline" 的数据管道，并在每天的午夜执行。它使用两个 S3DataNode 作为输入和输出位置，并使用 CopyActivity 将数据复制到输出位置。

请注意，上述示例仅用于说明如何使用 Terraform 创建数据管道。您需要根据自己的需求进行适当的调整和配置。
