CloudFormation create_stack 需要参数

如何解决CloudFormation create_stack 需要参数

我正在尝试创建一个用于制作 DynamoDB 表的 Cloud Formation 堆栈。我只是使用 AWS 提供的示例模板。

response = cf.create_stack(
    StackName = stack_name,TemplateURL = 'https://s3.us-west-2.amazonaws.com/cloudformation-templates-us-west-2/DynamoDB_Table.template',Parameters=[
        {
            'ParameterKey': 'AudioFiles','ParameterValue': 'string',},],TimeoutInMinutes=123,ResourceTypes=[
        'AWS::DynamoDB::Table',OnFailure='DO_nothing',EnableTerminationProtection=True
)

它返回此错误：

调用 CreateStack 操作时发生错误（ValidationError）：参数：[HashKeyElementName] must have values

我已尝试在参数部分中为此参数提供值，但这不起作用。

解决方法

我这样做很傻

Parameters=[
    {
        'HashKeyElementName': 'AudioFiles','ParameterValue': String',},],

代替这个

Parameters=[
    {
        'ParameterKey': 'HashKeyElementName','ParameterValue': 'AudioFiles',

您似乎没有提供 HashKeyElementName 参数的值。

response = cf.create_stack(
    StackName = stack_name,TemplateURL = 'https://s3.us-west-2.amazonaws.com/cloudformation-templates-us-west-2/DynamoDB_Table.template',Parameters=[
        {
            'ParameterKey': 'AudioFiles','ParameterValue': 'string','ParameterKey': 'HashKeyElementName','ParameterValue' : 'value'
        },TimeoutInMinutes=123,ResourceTypes=[
        'AWS::DynamoDB::Table',OnFailure='DO_NOTHING',EnableTerminationProtection=True
)

boto3 create_stack

在模板中，除HashKeyElementName外，所有参数均已默认模板摘录


 
  "Parameters" : {
    "HashKeyElementName" : {
      "Description" : "HashType PrimaryKey Name","Type" : "String","AllowedPattern" : "[a-zA-Z0-9]*","MinLength": "1","MaxLength": "2048","ConstraintDescription" : "must contain only alphanumberic characters"
    },"HashKeyElementType" : {
      "Description" : "HashType PrimaryKey Type","Default" : "S","AllowedPattern" : "[S|N]","MaxLength": "1","ConstraintDescription" : "must be either S or N"
    },"ReadCapacityUnits" : {
      "Description" : "Provisioned read throughput","Type" : "Number","Default" : "5","MinValue": "5","MaxValue": "10000","ConstraintDescription" : "must be between 5 and 10000"
    },"WriteCapacityUnits" : {
