DevOps Info Service (Python)

Python CI

Overview

The DevOps Info Service is a production-ready web application that reports detailed information about its runtime environment, system resources, and service status. This service will evolve throughout the DevOps course into a comprehensive monitoring tool.

  • pip

Installation

python -m venv venv
source venv/bin/activate
pip install -r requirements.txt

Running the Application

python app.py
# Custom configuration

HOST=127.0.0.1 PORT=3000 DEBUG=true python app.py
# http://127.0.0.1:3000

API Endpoints

  • GET / — Service, system, runtime, request info, and endpoint list.
  • GET /health — Health status and uptime (HTTP 200).

Configuration
