## Overview

This repository is a collection of DevOps templates, not one integrated application. Its documented product includes Node.js and Django container samples; the tree also includes Kubernetes deployment/scale/update manifests and an AWS CloudFormation LAMP autoscaling template. The sampled Node.js server handles a root request with a fixed response, while the Django URL configuration exposes the admin route. Compose and infrastructure details are represented conservatively because their contents were not sampled; notably, the Django settings excerpt names SQLite despite the template’s PostgreSQL label.

Main entry points: [`Django-PostgreSQL-app/composeexample/wsgi.py`](https://github.com/shorthairedpunk/devops-templates/blob/master/Django-PostgreSQL-app/composeexample/wsgi.py) (Django WSGI), [`nodejs-sample-app/server.js`](https://github.com/shorthairedpunk/devops-templates/blob/master/nodejs-sample-app/server.js) (Express server), [`Django-PostgreSQL-app/composeexample/urls.py`](https://github.com/shorthairedpunk/devops-templates/blob/master/Django-PostgreSQL-app/composeexample/urls.py) (Admin routing), [`Django-PostgreSQL-app/composeexample/settings.py`](https://github.com/shorthairedpunk/devops-templates/blob/master/Django-PostgreSQL-app/composeexample/settings.py) (Django settings)
