Chapter 4: Building Native ARM64 OCI Images for a Sample Application

Mon, 22 Jun 2026 00:00:00 +0000

Building container images that run natively on your Apple Silicon Mac is a critical step for achieving optimal performance in your local development environment. When you target the ARM64 architecture, you bypass the overhead of Rosetta 2 emulation, leading to faster build times, quicker container startup, and more responsive applications. This chapter guides you through creating a simple Python Flask API, defining its Dockerfile, and building an optimized ARM64 OCI (Open Container Initiative) image using nerdctl within your dedicated container machine.

Introduction

In the previous chapters, you’ve established a robust local container development environment on your Apple Silicon Mac, built a Linux container machine using Colima, efficiently mounted project volumes, and successfully built ARM64 OCI images for your sample application. Now, it’s time to share these images with the world, or at least with your team and deployment pipelines.

This chapter focuses on the critical step of authenticating your local container environment with a remote OCI (Open Container Initiative) registry and pushing your custom-built images. Whether you’re deploying to a Kubernetes cluster, sharing with collaborators, or simply archiving your work, a container registry is the central hub for image management.
