DevOps Hands-On Labs & Assignments

Overview

This repository contains my hands-on DevOps workshop assignments and practice labs completed using various DevOps and Cloud technologies. The exercises focus on practical implementation, Linux administration, CI/CD workflows, containerization, automation, and cloud-based deployments.

The labs were performed on Ubuntu virtual machines hosted on Google Cloud Platform (GCP).
