## Overview

This is a small Express smoke app intended for Docker/Kubernetes orchestration testing. An HTTP client reaches the server on port 3000, which registers three routes: a greeting, a health response, and a route that replies before terminating the process. The source excerpt supports the route behavior and listener; deployment configuration is not mapped because its contents were not provided.

Main entry points: [`app/app.js`](https://github.com/donguinesjay/node_docker_k8s/blob/main/app/app.js) (Express server)

## Connections

- HTTP client → Express server: sends HTTP requests (evidence: `app/app.js`)
- Express server → Home route: registers route (evidence: `app/app.js`)
- Express server → Health route: registers route (evidence: `app/app.js`)
- Express server → Crash route: registers route (evidence: `app/app.js`)
- Home route → HTTP client: sends greeting (evidence: `app/app.js`)
- Health route → HTTP client: sends status (evidence: `app/app.js`)
- Crash route → HTTP client: sends notice (evidence: `app/app.js`)
