Cloudformation S3bucket创建

Question

下面是我为创建一个简单的S3存储桶而编写的cloudformation模板，如何指定存储桶的名称？这是正确的方式吗？

      "-",

       {

       }, 
       {

       "deployment", 
       { 
       "Fn::FindInMap": [ 
        "RegionMap", 
        { 
        "Ref": "AWS::Region" 
        }, 
        "ShortRegion" 
       ] 
       } 
      ] 
      ] 
     },

    } 
    } 
} 

Answer 1

你的代码有BucketName已经规定：

"BucketName": { 
     "Fn::Join": [ 
     "-", 
     [ 
      { 
      "Ref": "ProductCode" 
      }, 
      { 
      "Ref": "StackEnvironment" 
      }, 
      "deployment", 
      { 
      "Fn::FindInMap": [ 
       "RegionMap", 
       { 
       "Ref": "AWS::Region" 
       }, 
       "ShortRegion" 
      ] 
      } 
     ] 
     ] 
    }, 

的BucketName是一个字符串，因为你使用的是“FN加入”，它会结合您要加入的功能。 “内部函数Fn :: Join将一组值附加到由指定分隔符分隔的单个值中。如果分隔符是空字符串，则该值集合将不带分隔符。” 你斗的名字，如果你不改变默认设置是： cloudops级-deplyment-yourAwsRegion

如果要更改默认的参数，那么这两个cloudops，舞台是可以改变的，部署硬编码，yourAWSRegion会从堆栈运行的地方拉出，并通过映射以短格式返回。

Answer 2

下面是一个非常简单的Cloudformation模板，用于创建S3存储桶，包括定义存储桶名称。

AWSTemplateFormatVersion: '2010-09-09' 
Description: create a single S3 bucket 

Resources: 
    SampleBucket: 
    Type: AWS::S3::Bucket 
    Properties: 
     BucketName: sample-bucket-0827-cc 

如果您希望AWS为您命名存储桶，也可以关闭“Properties：BucketName”行。然后它将看起来像$ StackName-SampleBucket- $ uniqueIdentifier。

希望这会有所帮助。
