Build Lambda Layer Guide

4-Step Approach

This guide covers the complete workflow for creating and deploying AWS Lambda layers using the aws_lambda_artifact_builder.layer subpackage. The layer creation process follows a systematic 4-step approach that ensures reproducible, optimized, and intelligently managed Lambda layers:

1. Build - Install and resolve dependencies using your preferred package manager

2. Package - Transform dependencies into Lambda-compatible zip files

3. Upload - Deploy artifacts to S3 storage for Lambda access

4. Publish - Create versioned Lambda layers with intelligent change detection

Guide Structure

This guide is organized to match the 4-step workflow, providing both step-by-step tutorials and comprehensive reference materials:

• Step 1: Build - Dependency Installation
• Step 2: Package Dependencies into Lambda Layer
• Step 3: Upload Layer Zip to S3 Storage
• Step 4: Publish Versioned Lambda Layer
• All-in-One Lambda Layer Workflow
