🐹 Go Webserver (Minimal Demo Backend)

A tiny Go webserver that runs as a non-root user and serves a simple HTML page showing:

• 🖥️ Hostname of the container
• 🌐 Container IP address
• 🔌 Listening port
• 📑 Request URI
• ⏰ Local time of the webserver

This image is intentionally very lightweight (FROM scratch), making it ideal for use as a backend in load balancing, Kubernetes, and Ingress/Gateway demos.

🚀 Quick Start

Run the container:

docker run -P batpool/main:kubernetes-test-image

This maps container port 8080 to a random free port on your host.
Check the mapping:

docker ps

Example output:

CONTAINER ID   IMAGE                                      PORTS
abc123...      batpool/main:kubernetes-test-image   0.0.0.0:49154->8080/tcp

Open your browser at:

http://localhost:49154

You’ll see a page like this:
