Cloudformation S3bucket创建

Question

这是我编写的用于创建简单S3存储桶的cloudformation模板，如何指定存储桶的名称？这是正确的方法吗？

Answer 1

要扩展“ cloudquiz”答案，这是它在yaml格式中的外观：

Resources:
  SomeS3Bucket:
    Type: AWS::S3::Bucket
    Properties:
      BucketName:
        Fn::Join: ["-", ["yourbucketname", {'Fn::Sub': '${AWS::Region}'}, {'Fn::Sub': '${Stage}'}]]

Answer 2

您的代码已指定BucketName：

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

BucketName是一个字符串，由于您使用的是“Fn Join”，它将与您加入的函数组合在一起。 “内部函数Fn :: Join将一组值附加到单个值中，由指定的分隔符分隔。如果分隔符是空字符串，则值集合没有分隔符。” 如果不更改默认值，则您的存储桶名称为： cloudops级-deplyment-yourAwsRegion

如果您更改默认参数，则可以更改cloudop和stage，部署是硬编码的，您的AWSRegion将从堆栈运行的位置拉出，并将通过Mapping以短格式返回。

这是一个非常简单的Cloudformation模板，可以创建一个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。然后它看起来像$ StackName-SampleBucket- $ uniqueIdentifier。

希望这有帮助。
