AWS 步骤和批量动态命令

我有一个带有单个作业定义的批处理作业，该作业定义根据环境命令选项上的参数执行。

原值为"--param2=XXX"但我需要根据 Step Functions 的输入参数使其保持动态。

{
  "param2": "--param2=YYY"
}

我无法将 Step Function 中的值替换为输入值

{
    "Step1": {
        "Type": "Task",
        "Resource": "arn:aws:states:::batch:submitJob.sync",
        "Parameters": {
            "JobDefinition": "arn:aws:batch:us-east-2:zzzzzzzzz:job-definition/XXXXXX",
            "JobQueue": "arn:aws:batch:us-east-2:zzzzzzzz:job-queue/YYYYYY",
            "JobName": "Step1",
            "ContainerOverrides": {
                "Environment": [
                    {
                        "Name": "envparam",
                        "Value": "0"
                    }
                ],
                "Command": [
                    "python",
                    "run.py",
                    "--param=val",
                    "$.param2"
                ]
            }
        },
        "Next": "Step2"
    }
}

我找到了一个解决方案，将参数添加到批处理中，并使用它进行引用Ref::Param2

这是完整的代码

{
    "Step1": {
        "Type": "Task",
        "Resource": "arn:aws:states:::batch:submitJob.sync",
        "Parameters": {
            "JobDefinition": "arn:aws:batch:us-east-2:zzzzzzzzz:job-definition/XXXXXX",
            "JobQueue": "arn:aws:batch:us-east-2:zzzzzzzz:job-queue/YYYYYY",
            "JobName": "Step1",
            "Parameters": {
                "Param2.$": "$.param2"
            },
            "ContainerOverrides": {
                "Environment": [
                    {
                        "Name": "envparam",
                        "Value": "0"
                    }
                ],
                "Command": [
                    "python",
                    "run.py",
                    "--param=val",
                    "Ref::Param2"
                ]
            }
        },
        "Next": "Step2"
    }
}
