AWS Data Pipeline 使用示例 AWS CLI

以下代码示例向您展示了如何使用with来执行操作和实现常见场景 AWS Data Pipeline。 AWS Command Line Interface

操作是大型程序的代码摘录,必须在上下文中运行。您可以通过操作了解如何调用单个服务函数,还可以通过函数相关场景的上下文查看操作。

每个示例都包含一个指向完整源代码的链接,您可以在其中找到有关如何在上下文中设置和运行代码的说明。

主题

操作

以下代码示例演示如何使用 activate-pipeline

AWS CLI

激活管道

此示例激活指定的管道:

aws datapipeline activate-pipeline --pipeline-id df-00627471SOVYZEXAMPLE

要在特定日期和时间激活管道,请使用以下命令:

aws datapipeline activate-pipeline --pipeline-id df-00627471SOVYZEXAMPLE --start-timestamp 2015-04-07T00:00:00Z

以下代码示例演示如何使用 add-tags

AWS CLI

向管道添加标签

此示例将指定的标签添加到指定的管道:

aws datapipeline add-tags --pipeline-id df-00627471SOVYZEXAMPLE --tags key=environment,value=production key=owner,value=sales

要查看标签,请使用 describe-pipelines 命令。例如,示例命令中添加的标签在 describe-pipelines 的输出中如下所示:

{ ... "tags": [ { "value": "production", "key": "environment" }, { "value": "sales", "key": "owner" } ] ... }

以下代码示例演示如何使用 create-pipeline
