Cloudformation S3bucket 创建

Question

这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？这是正确的方法吗？

Answer 1

您的代码已经指定了 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'，它将结合您要加入的函数。 "The intrinsic function Fn::Join appends a set of values into a single value, separated by the specified delimiter. If a delimiter is the empty string, the set of values are concatenated with no delimiter." 如果您不更改默认值，您的存储桶名称是： cloudops-stage-deplyment-yourAwsRegion

如果更改默认参数，则可以更改 cloudops 和 stage，部署是硬编码的，yourAWSRegion 将从堆栈所在的位置拉取运行，并将以短格式返回映射。

这是一个非常简单的 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，您也可以将 "Properties: BucketName" 行关闭。然后它看起来像 $StackName-SampleBucket-$uniqueIdentifier.

希望对您有所帮助。

要扩展 'cloudquiz' 答案，这是它在 yaml 格式中的样子：

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