# 参考：使用 EcsProperties 的 AWS Batch 作业场景
<a name="multi-container-jobs-scenarios"></a>

为了说明如何根据您的需求来构造使用 `EcsProperties` 的 AWS Batch 作业定义，本主题介绍了以下 [`RegisterJobDefinition`](https://docs.aws.amazon.com/batch/latest/APIReference/API_RegisterJobDefinition.html) 有效载荷。您可以将这些示例复制到文件中，根据需要对其进行自定义，然后使用 AWS Command Line Interface（AWS CLI）调用 `RegisterJobDefinition`。
