Engineering Domain: Containerization • Artifact Management • DevOps Infrastructure

Executive Summary

This project demonstrates the implementation of a private Docker image registry using Nexus Repository Manager. The objective was to provide a centralized and secure platform for storing, versioning, and distributing container images within a controlled environment.

Instead of relying solely on public registries, this implementation illustrates how organizations can manage their own container artifacts, improve software supply chain control, and support reliable deployment workflows. The project highlights practical experience with Docker image management, repository administration, and enterprise DevOps practices.

Project Objectives

The primary objectives of this project were to:

Configure Nexus Repository Manager as a private Docker registry.
Build and tag Docker images following consistent versioning practices.
Push container images to a private registry.
Pull images from the registry for deployment.
Demonstrate secure and centralized artifact management.
Understand how private registries integrate into modern CI/CD workflows.

Business Value

Container images are critical deployment artifacts in cloud-native environments. Organizations often use private registries to:

Protect proprietary application images.
Improve software supply chain security.
Control access to deployment artifacts.
Reduce reliance on public registries.
Maintain consistent application versions across environments.
