Hierarchical Storage: Firmware binaries stored as registry/{name}/{version}/firmware.bin
SQLite Database: Metadata storage with labels for flexible querying
REST API: Simple HTTP endpoints for upload, listing, and download
Version Management: Semantic versioning support

Quick Start

Prerequisites

Go 1.22 or later

Installation

Clone the repository:

git clone <repository-url>
cd spore-registry

Install dependencies:

go mod download

Run the server:

go run main.go

The server will start on port 3002 by default (or use PORT environment variable to change it).

API Endpoints

Upload Firmware

curl -X POST http://localhost:3002/firmware \
  -F "metadata={\"name\":\"base\",\"version\":\"1.0.0\",\"labels\":{\"app\":\"base\"}}" \
  -F "firmware=@firmware.bin"

List Firmware

# Get all firmware
curl http://localhost:3002/firmware

# Filter by name
curl "http://localhost:3002/firmware?name=base"

# Filter by version
curl "http://localhost:3002/firmware?version=1.0.0"

Download Firmware

curl http://localhost:3002/firmware/base/1.0.0 -o firmware.bin

Health Check

curl http://localhost:3002/health

Storage Structure

Firmware binaries are stored hierarchically:

registry/
├── base/
│   ├── 1.0.0/
│   │   └── firmware.bin
│   └── 1.1.0/
│       └── firmware.bin
└── sensor/
    └── 2.0.0/
        └── firmware.bin

Configuration

The registry uses the following environment variables:

PORT: Server port (default: 3002)

Database Schema

The SQLite database contains a firmware table:

CREATE TABLE firmware (
    id INTEGER PRIMARY KEY AUTOINCREMENT,
    name TEXT NOT NULL,
    version TEXT NOT NULL,
    size INTEGER NOT NULL,
    labels TEXT NOT NULL,
    created_at DATETIME DEFAULT CURRENT_TIMESTAMP,
    UNIQUE(name, version)
);
