Kubernetes Concepts Covered in this Repository:

Core Kubernetes Components & Architecture

1. Kubernetes Architecture - Control Plane, Worker Nodes, etcd, API Server, Scheduler, Controller Manager
2. Pods - NGINX Example - Smallest deployable units in Kubernetes
3. Services - NGINX Example - Network abstraction for accessing Pods
4. Deployments - NGINX Example - Declarative updates and lifecycle management for Pods
5. Namespaces - Virtual clusters for resource isolation and organization

Workload Controllers

6. DaemonSet - Examples - Ensures pods run on all/selected nodes

Configuration & Secrets Management

7. ConfigMaps - MySQL Example - Non-confidential configuration data
8. Secrets - MySQL Example - Sensitive information like passwords

Storage & Persistence

9. Persistent Volumes (PV) - Examples - Cluster-wide storage resources
10. Persistent Volume Claims (PVC) - Examples - Storage requests by users
11. Volume Mounts - MySQL Example - Attaching storage to containers

Networking & Traffic Management

12. Ingress - Examples - HTTP/HTTPS traffic routing and load balancing
13. Ingress Controllers - Setup Guide - Implementation of Ingress rules

Auto-scaling & Resource Management

14. Horizontal Pod Autoscaler (HPA) - Examples - Automatic scaling based on CPU/memory
15. Vertical Pod Autoscaler (VPA) - Examples - Automatic resource adjustment
16. Resource Requests & Limits - HPA Example - CPU and memory constraints

Security & Access Control

17. Role-Based Access Control (RBAC) - Examples - Fine-grained permissions
18. Roles & RoleBindings - Examples - Namespace-scoped permissions
19. Service Accounts - Examples - Identity for pods and processes

Node Management & Scheduling

20. Taints and Tolerations - Examples - Node scheduling constraints

Package Management & Templating

21. Helm Charts - Examples - Kubernetes package manager
22. Helm Templates - Apache Chart - Parameterized Kubernetes manifests
23. Helm Values - Apache Chart - Configuration management for charts

Deployment Strategies
