如何将stepfunction执行ID附加到SageMaker作业名称? [英] How to append stepfunction execution id to SageMaker job names?

问题描述

我有一个步进函数状态机，它创建了SageMaker批处理转换作业，定义是用Terraform编写的，我想将stepfunction执行ID添加到批处理转换作业名称中:

在stepfunction terraform文件中:

 定义= templatefile("stepfuntion.json"，{xxx) 

在"stepfuntion.json"中:

  {..."TransformJobName":"jobname-$$.Execution.Id"，}}，结束":是}}} 

但是在terraform应用之后，它没有生成实际的ID，而是给了我 jobname-$$.Execution.Id ，有人可以帮忙吗?

资源: https://docs.aws.amazon.com/step-functions/latest/dg/input-output-contextobject.html 要访问上下文对象，首先要选择参数名称，方法是在末尾附加.$，就像选择带有路径的状态输入时一样.然后，要访问上下文对象数据而不是输入，请在路径前添加$$..这告诉AWS Step Functions使用该路径在上下文对象中选择一个节点.

有人可以告诉我我想念什么吗?

解决方案

您尝试使用Terraform的var对此一无所知

jobname-$$.Execution.Id.

这是特定于步进"功能的东西，在状态机中可用，不适用于terraform.

I have a step function statemachine which creates SageMaker batch transform job, the definition is written in Terraform, I wanted to add the stepfunction execution id to the batch transform job names:

in stepfunction terraform file:

  definition = templatefile("stepfuntion.json",
    {
      xxxx
)

in the "stepfuntion.json":

{...
          "TransformJobName": "jobname-$$.Execution.Id",
  
          }
      },
        "End": true
      }
    }
  }

But after terraform apply, it didn't generate the actual id, it gave me jobname-$$.Execution.Id, can anyone help with this please?

Resources: https://docs.aws.amazon.com/step-functions/latest/dg/input-output-contextobject.html "To access the context object, first specify the parameter name by appending .$ to the end, as you do when selecting state input with a path. Then, to access context object data instead of the input, prepend the path with $$.. This tells AWS Step Functions to use the path to select a node in the context object."

Can someone tell me what I'm missing please?

解决方案

The var you are trying to use terraform doesn't know about it

jobname-$$.Execution.Id.

That's something specific to the Step function and available within state machine not available for terraform.
