## Overview

This repository is a collection of Docker learning examples, not one integrated application. The documented workflow is to build and run a Flask example, then explore Docker volumes and MySQL persistence. Other examples demonstrate image-record uploads, PHP registration/login, and Flask/MySQL login. Source excerpts show those applications’ database operations; the README documents volume-backed MySQL, but does not identify how the static volume example is mounted. Compose and container wiring are not mapped because their contents were not provided.

Main entry points: [`mysql`](https://github.com/devnotops/docker/tree/main/mysql) (MySQL), [`project1/web2-app/config.php`](https://github.com/devnotops/docker/blob/main/project1/web2-app/config.php) (PHP DB Setup), [`project1/python-app/main.py`](https://github.com/devnotops/docker/blob/main/project1/python-app/main.py) (Image Record Uploader), [`project1/web2-app/index.php`](https://github.com/devnotops/docker/blob/main/project1/web2-app/index.php) (PHP Registration)
