Overview

This repository is part of my learning journey in Kubernetes.
It contains basic resource definitions used on Day 1 of studying Kubernetes — covering Pods, Namespaces, Deployments, etc., to understand how Kubernetes workloads are defined and run.

---

Objectives

• Understand the basic Kubernetes resource types: Pod, Namespace, Deployment.
• Practice writing YAML manifests for these resources.
• Deploy simple applications in Kubernetes and observe how they work.
• Learn how Kubernetes schedules workloads inside namespaces and how to define deployments.

---

Repository Structure

File	Purpose
namespace.yml	Defines a Kubernetes Namespace for isolating resources.
pod.yml	Defines a Pod resource (single container).
deployment.yml	Defines a Deployment resource (manages replicas, rollouts).

---

Prerequisites

To use these manifests, you will need:

• A Kubernetes cluster (kind / minikube / k3s / GKE / EKS / AKS / etc.)
• kubectl configured to talk to your cluster
• Basic knowledge of kubectl commands

---

Usage

Here’s how you can apply the configurations in this repository:

Create the namespace

kubectl apply -f namespace.yml

Verify namespace was created

kubectl get namespaces

Deploy a Pod (inside the namespace)

kubectl apply -f pod.yml -n nginx-test

Check pods

kubectl get pods -n nginx-test

Deploy a Deployment

kubectl apply -f deployment.yml -n nginx-test

Check deployment status, replicas, etc.

kubectl get deployments -n nginx-test
kubectl get pods -n nginx-test
