🚢 Kubernetes Deployment Mastery

📋 Project Overview

This project demonstrates advanced Kubernetes deployment capabilities, showcasing both declarative and imperative approaches to managing containerized applications. Through this implementation, I've developed a deep understanding of Kubernetes Deployments, ReplicaSets, and Pod management, using Nginx as the example application.

🎯 Key Objectives

• Implement production-grade Kubernetes Deployments using both declarative and imperative approaches
• Master Pod lifecycle management and scaling strategies
• Develop expertise in Kubernetes manifest creation and management
• Establish best practices for container orchestration
• Gain hands-on experience with real-world deployment scenarios

🏗️ Project Architecture

The architecture implements a Kubernetes Deployment that manages a single ReplicaSet, which in turn maintains three identical Nginx pods running the latest Nginx image. Each pod runs a containerized Nginx web server exposing port 80, while the ReplicaSet ensures that the specified number of replicas (3) is maintained at all times.

Loading

💻 Technical Stack

• Container Orchestration: Kubernetes
• Container Runtime: Docker
• Web Server: Nginx
• Infrastructure: kubectl, Linux

🚀 Getting Started

🐳 Prerequisites

• Kubernetes cluster (local or cloud-based)
• kubectl CLI tool installed
• Docker installed
• Basic understanding of container orchestration
• vim text editor (optional)

⚙️ Installation

1. Clone the repository:

   git clone https://github.com/TheToriqul/k8s-deployment.git

2. Navigate to the project directory:

   cd k8s-deployment

3. Ensure kubectl is properly configured:

   kubectl cluster-info

🎮 Usage

Declarative Approach

1. Apply the deployment configuration:

   kubectl apply -f deployment-definition.yaml

Imperative Approach

1. Create deployment directly:

   kubectl create deployment nginx-deployment --image=nginx:latest --replicas=3 --port=80

For detailed commands and explanations, refer to the reference-commands.md file.
