README

A minimal Docker wrapper for Laravel Zero, inspired by Laravel Sail but designed specifically for CLI applications.

✨ Features

• 🚀 Ephemeral Containers - Each command runs in a fresh container, no daemon needed
• 🎯 Auto-detection - Automatically detects your application binary from composer.json
• 🐘 Multi PHP Version - Support for PHP 8.2, 8.3, and 8.4
• 🪶 Alpine-based - Ultra-lightweight images (~50MB vs ~1GB)
• 📦 Ready to use - One command installation

📋 Requirements

• Docker Desktop (macOS/Windows) or Docker Engine (Linux)
• Docker Compose v2+
• A Laravel Zero project

🚀 Installation

composer require dimer47/zero --dev

Publish the Docker configuration:

php application zero:install

This will:

• Create docker-compose.yml - Docker Compose configuration
• Set PHP_VERSION in your .env file (created if needed)

You can specify a different PHP version:

php application zero:install --php=8.4

Build the Docker image:

./vendor/bin/zero build

🎯 Shell Alias (Recommended)

For a better developer experience, add this alias to your shell configuration (~/.zshrc or ~/.bashrc):

alias zero='$([ -f zero ] && echo ./zero || echo ./vendor/bin/zero)'

Then reload your shell:

source ~/.zshrc  # or source ~/.bashrc

Now you can use zero directly instead of ./vendor/bin/zero:

zero list
zero build
zero pest

📖 Usage

🎯 Application Commands

# List all available application commands
./vendor/bin/zero list

# Run any application command (binary auto-detected from composer.json)
./vendor/bin/zero server:list
./vendor/bin/zero make:command MyCommand

⚡ Laravel Zero Commands

# Run tests
./vendor/bin/zero test

# Build PHAR executable (output in builds/ directory)
./vendor/bin/zero app:build my-app

# Install optional components
./vendor/bin/zero app:install

# Rename your application
./vendor/bin/zero app:rename my-new-name

# Create a new command
./vendor/bin/zero make:command

# Create a new test
./vendor/bin/zero make:test

🐘 PHP & Composer

# Run PHP commands
./vendor/bin/zero php -v
./vendor/bin/zero php script.php

# Run Composer commands
./vendor/bin/zero composer install
./vendor/bin/zero composer require vendor/package
./vendor/bin/zero composer update

🧪 Testing & Code Style

# Run Pest tests
./vendor/bin/zero pest
./vendor/bin/zero pest --filter=MyTest
./vendor/bin/zero pest --coverage

# Run Pint code style fixer
./vendor/bin/zero pint
./vendor/bin/zero pint --test      # Check without fixing
./vendor/bin/zero pint --dirty     # Only changed files
./vendor/bin/zero pint app/        # Specific directory

🐚 Container Access

# Start an interactive shell
./vendor/bin/zero shell
./vendor/bin/zero bash

🐳 Docker Management

# Build the Docker image
./vendor/bin/zero build

# Rebuild without cache
./vendor/bin/zero build --no-cache

⚙️ Configuration

Environment Variables

Create a .env file at your project root:

# PHP version (8.2, 8.3, or 8.4)
PHP_VERSION=8.3

# UID/GID for file permissions (match your local user)
ZEROUSER=1000
ZEROGROUP=1000

🏷️ Multiple Projects

By default, all Laravel Zero projects using the same PHP version share the same Docker image (zero-8.3/app). This is efficient for most use cases since the image only contains PHP and system extensions, while your code and dependencies are mounted via volumes.

However, if you need to customize the Docker image for a specific project (e.g., adding extra PHP extensions), you can isolate it by setting COMPOSE_PROJECT_NAME in your .env:

COMPOSE_PROJECT_NAME=my-project

This will create a separate image named my-project-zero-8.3/app, preventing conflicts with other projects.

Docker Compose

The default docker-compose.yml:

services:
    laravel.zero:
        build:
            context: ./vendor/dimer47/zero/runtimes/${PHP_VERSION:-8.3}
            dockerfile: Dockerfile
            args:
                ZEROGROUP: '${ZEROGROUP:-1000}'
                ZEROUSER: '${ZEROUSER:-1000}'
        image: zero-${PHP_VERSION:-8.3}/app
        extra_hosts:
            - 'host.docker.internal:host-gateway'
        environment:
            ZEROUSER: '${ZEROUSER:-1000}'
            ZEROGROUP: '${ZEROGROUP:-1000}'
        volumes:
            - '.:/var/www/html'
        networks:
            - zero
networks:
    zero:
        driver: bridge

🔧 How It Works

Unlike Laravel Sail which runs a persistent container, Zero uses ephemeral containers optimized for CLI workflows:

1. 📦 Each command spawns a new container
2. ⚡ The command executes
3. 🗑️ The container is automatically removed

This approach is more efficient for CLI applications where you run occasional commands rather than maintaining a web server.

🎯 Binary Auto-Detection

Zero automatically reads your composer.json to find your application binary:

{
    "bin": ["my-app"]
}

This means ./vendor/bin/zero list will execute php my-app list inside the container.

🔌 PHP Extensions

The Docker images include essential extensions for Laravel Zero:

• PDO / PDO MySQL
• Zip
• MBString
• Intl
• PCntl
• BCMath

The images also include useful system tools: git, curl, jq (JSON parsing), composer.

Adding Extensions

To add more PHP extensions, create your own Dockerfile extending the base image, or copy the runtime to your project and customize it.
