Kubernetes Learning Repository

Welcome to the Kubernetes (k8s) Learning Repository! This repository is a comprehensive, hands-on guide to mastering Kubernetes fundamentals through practical examples, commands, and configurations.

Quick Links

Note: More sections on advanced topics like ConfigMaps, Secrets, Ingress, Helm, and more will be added soon!

What This Repository Contains

This repository is organized into topic-specific directories, each containing:

• Detailed README.md files: Step-by-step guides with kubectl commands, YAML configurations, and explanations.
• Sample YAML files: Ready-to-use configuration files for resources like pods, deployments, services, etc.
• Best Practices and Notes: Tips, cautions, and discussions on when to use specific resources.

The content focuses on core Kubernetes concepts, using nginx as a common example application for simplicity. All examples assume a running Kubernetes cluster (e.g., Minikube, Kind, or a cloud-based cluster) and kubectl configured for access.

How to Use This Repository

1. Setup Your Environment:

   • Install Kubernetes (e.g., via Minikube, or Kind for local development).
   • Ensure kubectl is installed and connected to your cluster: kubectl cluster-info.
   • Clone this repository: git clone https://github.com/ijas9118/k8s.git.

2. Navigate and Learn:

   • Start with the Pods section for the basics.
   • Follow the Table of Contents to progress through topics.
   • Read each README.md for theory, commands, and YAML examples.
   • Copy YAML files to your local environment and apply them with kubectl apply -f <file.yaml>.

3. Hands-On Practice:

   • Run the provided kubectl commands in your terminal.
   • Complete the tasks in each section to build and test resources.
   • Experiment with modifications (e.g., scaling replicas, changing images) to deepen understanding.
   • Use kubectl describe and kubectl logs for debugging.

4. Cleanup:

   • Delete resources after testing: e.g., kubectl delete -f <file.yaml> or kubectl delete ns <namespace>.
   • For local clusters, reset with minikube delete if needed.
