Provides AWS CloudFormation patterns for Amazon S3. Use when creating S3 buckets, policies, versioning, lifecycle rules, and implementing template structure with Parameters, Outputs, Mappings, Conditions, and cross-stack references.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# AWS CloudFormation S3 Patterns

Provides S3 bucket configurations, policies, versioning, lifecycle rules, and CloudFormation template structure best practices for production-ready infrastructure.

## When to Use

- Creating S3 buckets with custom configurations
- Implementing bucket policies for access control
- Configuring S3 versioning for data protection
- Setting up lifecycle rules for data management
- Creating Outputs for cross-stack references
- Using Parameters with AWS-specific types
- Organizing templates with Mappings and Conditions

## Overview

S3 bucket configurations, policies, versioning, lifecycle rules, and CloudFormation template structure for production-ready infrastructure.

## Instructions

1. **Define Bucket Resources**: Create `AWS::S3::Bucket` with versioning, encryption, PublicAccessBlock
2. **Configure Bucket Policy**: Set up IAM policies for access control
3. **Set Up Lifecycle Rules**: Define transitions and expiration policies
4. **Configure CORS**: Allow cross-origin requests if needed
5. **Add Outputs**: Export bucket names/ARNs for cross-stack references

**Validate before deploy:**
```bash

How to install

The exact contents, by fingerprint
mdr add giuseppe-trisciuoglio/developer-kit/aws-cloudformation-s3@sha256:3866a5adf45aa6fd

The line at the top of this page pins the label git:20260324.a02e282, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
