🔗 Kubernetes Namespace Management: Resource Isolation & Organization

📋 Project Overview

This project demonstrates my expertise in implementing and managing Kubernetes namespaces for resource isolation and multi-team workload organization. Through hands-on implementation, I've developed a comprehensive understanding of namespace management using both imperative commands and declarative YAML configurations, showcasing my ability to design and maintain segregated environments within Kubernetes clusters.

🎯 Key Objectives

• Implement resource isolation strategies using Kubernetes namespaces
• Master both imperative and declarative approaches to namespace management
• Deploy and manage workloads across different namespaces
• Develop expertise in namespace-based access control
• Establish best practices for multi-environment resource organization

🏗️ Project Architecture

Kubernetes Namespace Architecture

The architecture demonstrates a Kubernetes cluster's namespace organization, featuring a default namespace alongside multiple custom namespaces. Each custom namespace encapsulates its own dedicated resources - including pods and services - enabling clear separation of workloads. This isolation pattern allows for independent resource management and access control while maintaining logical organization within the cluster.

💻 Technical Stack

• Container Orchestration: Kubernetes
• Container Runtime: Docker
• Configuration: YAML
• Operating System: Linux
• Command Line Tools: kubectl

🚀 Getting Started

🐳 Prerequisites

• Kubernetes cluster (local or cloud-based)
• kubectl CLI tool
• Basic understanding of YAML
• vim text editor (for configuration)

⚙️ Installation

1. Clone the repository:

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

2. Navigate to the project directory:

   cd k8s-namespace

3. Ensure kubectl is properly configured:

   kubectl cluster-info

🎮 Usage

1. Create a new namespace:

   kubectl create namespace my-namespace

2. Deploy resources to the namespace:

   kubectl apply -f pod.yaml -n my-namespace

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