Manual Docker only — create code yourself, then build & run

This is the only way documented for this project.

You will:

Create folders and every source file yourself (PHP or Node)
Paste code from the linked files (or from the blocks below)
Write a Dockerfile piece by piece
docker pull images
docker network create
docker volume create (named volumes only — no host folder bind mounts)
docker build (code goes into the image with COPY)
docker run MySQL + app

You create .env + docker-compose.yml before running. Use manual docker run or docker compose up. There is no “mount ./application from the host”. Code is copied into the image at build time. Named volumes only hold MySQL data and uploaded files.

How code gets into the container

You create files on your PC
        ↓
Dockerfile: COPY application/ ...
        ↓
docker build   →  files baked into YOUR image
        ↓
docker run     →  container runs that image

Uploads / MySQL data use named volumes (created with docker volume create), not Windows folder mounts.

One-time: Docker in WSL

sudo service docker start
docker --version

If Docker is not installed yet, follow the install section in GUIDE.md (WSL + Docker Engine only).

Pick one stack

Stack	Working folder you will create	Browser	MySQL port
PHP	`~/docker-task-php` (or any empty folder)	http://localhost:8080	3306
Node	`~/assignment-docker-node`	http://localhost:3000	3307

Reference copies of the finished code already live under:

PHP: php-app/application/
Node: nodejs-app/application/ (server.js + public/style.css), nodejs-app/database.sql

Open those links in your editor if you prefer copy-from-file instead of paste-from-guide.

Linked source files (quick index)

PHP — create these yourself

You create	Open / copy from
`application/db.php`	php-app/application/db.php
`application/style.css`	php-app/application/style.css
`application/favorites.js`	php-app/application/favorites.js
`application/index.php`	php-app/application/index.php
`application/create.php`	php-app/application/create.php
`application/edit.php`	php-app/application/edit.php
`application/delete.php`	php-app/application/delete.php
`application/favorites.php`	php-app/application/favorites.php
`Dockerfile`	php-app/Dockerfile

Node — create these yourself

You create	Open / copy from
`package.json`	nodejs-app/package.json
`application/server.js`	nodejs-app/application/server.js
`application/public/style.css`	nodejs-app/application/public/style.css
`Dockerfile`	nodejs-app/Dockerfile (manual version above uses `npm install`)

Database SQL

Task	File
Create DB / user / table	setup-database.html · setup.sql
Node init script (Compose auto-runs on a fresh MySQL volume)	nodejs-app/database.sql

What you prove for the assignment

Concept	How you prove it manually
Images	`docker pull` + `docker images` + your `docker build` image
Dockerfile	You wrote it; `COPY` puts code in the image
Containers	`docker run` / `docker ps` / `docker rm`
Volumes	`docker volume create` + `-v name:/path` (not host bind mount)
Networking	`docker network create` + `--network-alias db` + `DB_HOST=db`
Persistence	Delete containers, re-run with same volumes

Rules for this project (summary)

Do	Don’t
Create every `.php` / `.js` file yourself	Rely on compose as the main demo
`COPY` code in Dockerfile + `docker build`	Bind-mount source code with `-v ./app:...`
`docker volume create` for MySQL + uploads	Only use a host `./uploads` folder as the “volume story”
`docker pull` then `docker run`	Hide everything behind one `compose up`

You are building, pulling, networking, and volumizing by hand. That is the whole point.
