Install Docker** - Deploys Docker Engine and Docker Compose
Install Kubernetes** - Sets up K3s cluster with kubectl, Helm, and k9s
Install Jenkins** - Configures Jenkins CI/CD server with Docker integration
Install Monitoring** - Deploys Prometheus and Grafana using Helm charts
Create DevOps User** - Establishes a dedicated user with appropriate permissions
Security Configuration** - Implements firewall, VS Code, and Terraform
Final Configuration** - Sets up sample projects and configuration files
Setup Complete** - Provides a summary and access details

Essential Prerequisites
Linux server with SSH access
Root-level administrative privileges
