Building multi-arch containers with GitHub Actions in AWS

This article provides a comprehensive guide to building multi-architecture container images using GitHub Actions, AWS CodeBuild, and Amazon ECR. The solution enables developers to create container images compatible with both x86 and AWS Graviton architectures.

• Demonstrates how to set up GitHub Actions workflow for multi-arch container builds
• Creates two CodeBuild projects for x86 and arm64 compute environments
• Configures IAM roles and ECR repository for image storage
• Uses GitHub Actions secrets to manage AWS credentials
• Builds and pushes separate images for each architecture, then creates a manifest list

The solution provides a streamlined approach for developers to create container images that can run on different computing architectures, improving flexibility and performance across hardware platforms.
