Amazon web services 创建从参数文件读取的更改集

问题 我正在运行createchangeset命令，该命令将查找参数文件，但收到一条CLI错误消息

代码

aws cloudformation create-change-set --stack-name  arn:aws:cloudformation:eu-west-1:xxxxxxxxxxxxxx:stack/JM-MachineLearning/0846dff0-5f91-11e9-8422-0a9391483dc6 --template-body packaged.yaml --parameters teststackupdate.json --change-set-name SampleChangeSet2

我要做的是更新AWS Cloudformation中的堆栈。 我从SAM通过CLI创建了堆栈，转换成Cloudformation，然后部署

我确实通过CLI运行了该命令，但这也不起作用 ParameterKey=string，ParameterValue=string，UsePreviousValue=boolean，ResolvedValue=string

通过CLI运行参数

aws cloudformation create-change-set --stack-name arn:aws:cloudformation:eu-west-1:xxxxxxxxxxx:stack/JM-MachineLearning/0846dff0-5f91-11e9-8422-0a9391483dc6 --change-set-name SampleChangeSet2  --parameter LambdaFunctionName=MachineLearningMementoDynamoDBSaver nameTableEvent=MachineLearningEvent nameTableCountersEvent=MachineLearningCountersEventId nameTableCountersEventRowId=MachineLearningCountersEventRowId serverName=LambdaMachineLearning KinesisName=MachineLearningDataStream payloadBucketName=redcloud-machinelearning-6888/memento/error-payload --profile DEV  --region eu-west-1

Parameter validation failed:
Unknown parameter in Parameters[0]: "LambdaFunctionName", must be one of: ParameterKey, ParameterValue, UsePreviousValue, ResolvedValue
Unknown parameter in Parameters[1]: "nameTableEvent", must be one of: ParameterKey, ParameterValue, UsePreviousValue, ResolvedValue
Unknown parameter in Parameters[2]: "nameTableCountersEvent", must be one of: ParameterKey, ParameterValue, UsePreviousValue, ResolvedValue
Unknown parameter in Parameters[3]: "nameTableCountersEventRowId", must be one of: ParameterKey, ParameterValue, UsePreviousValue, ResolvedValue
Unknown parameter in Parameters[4]: "serverName", must be one of: ParameterKey, ParameterValue, UsePreviousValue, ResolvedValue
Unknown parameter in Parameters[5]: "KinesisName", must be one of: ParameterKey, ParameterValue, UsePreviousValue, ResolvedValue
Unknown parameter in Parameters[6]: "payloadBucketName", must be one of: ParameterKey, ParameterValue, UsePreviousValue, ResolvedValue

任何建议都会被提出

我是新来的

谢谢编辑：再想一想，这可能不是你的问题，但一定要试试看错误是否会改变。希望其他人能提供更好的答案

在teststackupdate.json中，您有：

"UsePreviousValue": "true"

"UsePreviousValue": true

您的true在引号中，使其成为字符串。 错误告诉您它需要是布尔值，即true/false

取消引用所有“true”，使其看起来像：
