Buckie PHP

PHP 8+ implementation of Buckie — a filesystem-native file server with a minimal S3-style REST API.

Designed for shared hosting and standard PHP environments: no framework, no database, no message broker. Just PHP and a disk.

Standalone application — Buckie PHP runs as a self-contained CLI tool and/or HTTP server. It is not a reusable library to be required inside another project.

Usage modes

Mode	How	Description
CLI	`php bin/buckie <command>`	Manage buckets, identities, files and permissions from the terminal
HTTP server (dev)	`php bin/buckie serve`	Starts PHP's built-in server — useful for local development
HTTP server (prod)	Apache / Nginx / FrankenPHP	Deploy `public/index.php` under any standard PHP web server

Features

Zero external dependencies — only PHP 8.0+ and standard extensions (GD, finfo)
Single config file — all state lives in .buckie/config.json
On-the-fly thumbnails — GD (default) or Imagick; automatic caching
Same REST API as the Node.js implementation
Same CLI contract as the Node.js implementation
Local FS only — no SFTP; ideal for shared hosting
Authentication via X-Buckie-Identity/X-Buckie-Secret headers or HTTP Basic Auth
Secret hashing with password_hash(PASSWORD_DEFAULT) (bcrypt) — cross-compatible with the Node.js implementation
Staging + atomic rename for uploads — no partial reads

Requirements

Requirement	Minimum
PHP	8.0
Composer	2+
GD extension	any recent version (or Imagick)
finfo extension	bundled with PHP 8

Installation

Option A — create-project (recommended)

composer create-project dynamia-tools/buckie buckie-php
cd buckie-php

This installs Buckie as a standalone application in the buckie-php/ directory.

Option B — clone + install

git clone https://github.com/dynamia-tools/buckie buckie-php
cd buckie-php/buckie-php
composer install

Make the CLI available globally

# Link the binary to a directory in your $PATH
ln -s "$(pwd)/bin/buckie" ~/.local/bin/buckie
chmod +x ~/.local/bin/buckie

Quick Start

As a CLI tool

All management operations (buckets, identities, permissions, files) are handled through the buckie CLI:

# Create a bucket
php bin/buckie create bucket documents /var/storage/documents

# Create an identity
php bin/buckie create identity erp-prod my-secret-password

# Grant permissions
php bin/buckie grant erp-prod documents --read --write --delete --prefix /tenant-a/

# List all buckets
php bin/buckie list buckets

# Upload a file directly from the terminal
php bin/buckie upload documents tenant-a/invoice.pdf ./invoice.pdf

Run php bin/buckie --help to see all available commands.

As an HTTP server (development)

php bin/buckie serve --host 0.0.0.0 --port 8080

As an HTTP server (production)

Deploy the public/ directory under Apache, Nginx or FrankenPHP (see Production Deployment below).

Production Deployment

Buckie PHP is deployed like any standard PHP application. Set the document root to the public/ directory.

Apache

Make sure mod_rewrite is enabled. The public/.htaccess file already contains the required configuration.

<VirtualHost *:80>
    ServerName storage.example.com
    DocumentRoot /var/www/buckie/public

    <Directory /var/www/buckie/public>
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>

Nginx

server {
    listen 80;
    server_name storage.example.com;
    root /var/www/buckie/public;
    index index.php;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ \.php$ {
        fastcgi_pass unix:/run/php/php8.0-fpm.sock;
        fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
        include fastcgi_params;
    }
}

FrankenPHP

frankenphp php-server --root public/

Docker (pruebas locales con Apache)

El repositorio incluye un Dockerfile y un docker-compose.yml listos para pruebas locales.

# 1. Construir la imagen e iniciar el contenedor
docker compose up --build -d

# 2. Verificar que el servicio está activo
curl http://localhost:8080/health

# 3. Crear un bucket (la ruta debe existir DENTRO del contenedor)
docker exec buckie-php php bin/buckie create bucket docs /var/buckie-storage/docs

# 4. Crear una identidad
docker exec buckie-php php bin/buckie create identity dev-user secret123

# 5. Otorgar permisos
docker exec buckie-php php bin/buckie grant dev-user docs --read --write --delete

# 6. Subir un archivo de prueba
curl -X PUT http://localhost:8080/docs/hello.txt \
  -H "X-Buckie-Identity: dev-user" \
  -H "X-Buckie-Secret: secret123" \
  -H "Content-Type: text/plain" \
  --data-binary "Hola desde Buckie PHP 🚀"

# 7. Descargar el archivo
curl http://localhost:8080/docs/hello.txt \
  -H "X-Buckie-Identity: dev-user" \
  -H "X-Buckie-Secret: secret123"

# 8. Detener el contenedor
docker compose down

Differences from the Node.js Implementation

Feature	Node.js	PHP
Storage backends	Local FS + SFTP	Local FS only
Secret hashing	bcrypt (`bcrypt` npm)	`password_hash` / bcrypt
Hash interoperability	✅ Compatible	✅ Compatible
HTTP server	Fastify	PHP built-in / Apache / Nginx / FrankenPHP
File streaming	Node.js streams	`fpassthru`
Thumbnails	Sharp	GD / Imagick
Programmatic API	Full SDK	Not available

Security

Private by default — every request requires authentication; only /health is public
bcrypt password hashing — secrets are never stored in plain text; hashes are cross-compatible with the Node.js implementation
Prefix-based authorization — access can be restricted by bucket and path prefix
Path traversal protection — canonical path validation on every request
Staging + atomic commit — uploads are written to staging first to prevent partial reads
