Go-Health-Monitor 🚀

A high-performance, concurrent CLI tool built in Go to monitor website availability. This project demonstrates core Go concepts like Goroutines, Channels, and Structs, packaged as a lightweight Docker container.

🛠 Features

• Concurrent Execution: Uses Goroutines to check multiple URLs simultaneously rather than one-by-one.
• Thread-Safe Communication: Implements Go Channels to synchronize results back to the main thread.
• Robust Error Handling: Captures network timeouts and DNS errors using a custom res struct.
• Containerized: Multi-stage Docker build resulting in a tiny footprint (<20MB).

🚀 Getting Started

Prerequisites

• Go 1.21+ (if running locally)
