[Docker] Setup Docker Environment for Fresh Laravel Web Project

DockerLaravelSetupNotes.md

Courtesy

This notes is simplify version of long series of Docker Setup for local web development project write by tech.osteel.me. Adjustments were made based on my habit and repetitive step when starting new laravel new project.

Preparation

1. Ensure Docker Desktop with Docker Compose has been installed.
2. Create project folder (for example: /Users/macto/Development/laravel-project).
3. Change project name inside this notes with yours.
   • For folder: laravel-project.
   • For inside config files: laravelproject.
4. In this notes I use only below services:
   • laravel (as backend)
   • mysql (as database)
   • phpmyadmin (as database management ui)

Folder Structure

final folder structure for this setup as per below:

laravel-project/
├── .docker/
│   ├── mysql/
│   │   └── my.cnf
│   └── nginx/
│       └── conf.d/
│           └── backend.conf
│           └── phpmyadmin.conf
├── src/
│   └── backend/
│       └── Dockerfile
├── .env
├── .env.example
├── .gitignore
└── docker-compose.yml

Create docker-compose.yml

• Copy, paste and save as docker-compose.yml for below minimal configuration:

version: '3.8'

FROM nginx:1.19-alpine

# Install packages
RUN apk --update --no-cache add openssl

Setup Backend Dockerfile

• create backend folder in laravel-project/src/
• create Dockerfile file in laravel-project/src/backend/
• copy below code:

FROM php:8.0-fpm-alpine as backend

• copy below code:

server {
    listen      443 ssl http2;
    listen      [::]:443 ssl http2;

    # Create .env file
    cat > "/var/www/backend/.env" << EOF
APP_NAME=laravelproject
APP_ENV=local
APP_KEY=
APP_DEBUG=true
APP_URL=http://backend.laravelproject.test

LOG_CHANNEL=single

DB_CONNECTION=mysql
DB_HOST=mysql

DB_DATABASE=laravelproject
DB_USERNAME=root
DB_PASSWORD=root

BROADCAST_DRIVER=log
CACHE_DRIVER=file
QUEUE_CONNECTION=redis
REDIS_HOST=redis
SESSION_DRIVER=file
EOF

    # Generate application key
    php "/var/www/backend/artisan" key:generate --ansi
fi

# Database
php "/var/www/backend/artisan" migrate

$ chmod +x .docker/backend/init

Create bash script for automating or simplify commands

• create laravelproject.sh in laravel-project root folder
