What is AWS S3 Bucket CloudFormation

CloudFormation is Amazon's IaC service that allows for the creation, management, and provisioning of AWS and third-party resource collections across accounts and regions. All of this can be done through code, also, S3 buckets, EC2 instances, Amazon S3 encryption, databases, etc, can be defined via JSON or YAML.

AWS CloudFormation Templates for S3 Bucket

A basic CloudFormation template typically consists of the following components: AWSTemplateFormationVersion, Description, and Resources. What follows is a basic example of a CloudFormation template creating an S3 storage bucket.

→Example 1: Simple S3 Bucket Template (YAML Format)

AWSTemplateFormatVersion: '2010-09-09'
Description: Simple CloudFormation Template to create an S3 bucket
 
Resources:
MyS3Bucket:
Type: AWS::S3::Bucket
Properties:
BucketName: my-cloudformation-bucket

→Example 2: S3 Bucket with Versioning and Lifecycle Rules

AWSTemplateFormatVersion: '2010-09-09'
Description: S3 Bucket with Versioning and Lifecycle Rules
 
Resources:
VersionedS3Bucket:
Type: AWS::S3::Bucket
Properties:
BucketName: my-versioned-bucket
VersioningConfiguration:
Status: Enabled
LifecycleConfiguration:
Rules:
- Id: CleanupRule
>Status: Enabled
ExpirationInDays: 30
Prefix: "logs/"
NoncurrentVersionExpirationInDays: 60

→Example 3: S3 Bucket with Server-Side Encryption

AWSTemplateFormatVersion: '2010-09-09'
Description: S3 Bucket with Server-Side Encryption (SSE-S3)
 
Resources:
EncryptedS3Bucket:
Type: AWS::S3::Bucket
Properties:
BucketName: my-encrypted-bucket
BucketEncryption:
ServerSideEncryptionConfiguration:
- ServerSideEncryptionByDefault:
SSEAlgorithm: AES256

→Example 4: S3 Bucket with Bucket Policy

AWSTemplateFormatVersion: '2010-09-09'
Description: S3 Bucket with Bucket Policy to restrict public access
 
Resources:
SecuredS3Bucket:
Type: AWS::S3::Bucket
Properties:
BucketName: my-secured-bucket
 
SecuredS3BucketPolicy:
Type: AWS::S3::BucketPolicy
Properties:
Bucket: !Ref SecuredS3Bucket
PolicyDocument:
Version: '2012-10-17'
Statement:
- Effect: Deny
Principal: '*'
Action: 's3:*'
Resource: !Sub '${SecuredS3Bucket.Arn}/*'
Condition:
Bool:
'aws:SecureTransport': 'false'

How to Use CloudFormation to Create S3 Bucket

AWS S3 bucket policy CloudFormation enables you to create and manage S3 buckets as code, here are the detailed steps to create S3 buckets using CloudFormation.

📌Note: Before heading into creating an S3 bucket, you need to make sure there is CloudFormation permission for users to create, update, and delete stacks. And also the S3 bucket name is globally unique.

Step 1. Create a New Bucket

In the AWS console homepage, navigate to S3 > Create bucket to open the create page, then select Enable and Amazon S3-managed keys (SSE-S3).

Step 2. Upload the CloudFormation Template to AWS

1. In the AWS console homepage, navigate to CloudFormation > Create stack > With new resource (standard).

Step 3. Monitor the Creation Process

Once you click Create stack, the CloudFormation will start the creation process. When the process is complete, you can see the created resources in the Resources tab.
