Orchard

Content-Addressable Storage System

Orchard is a centralized binary artifact storage system that provides content-addressable storage with automatic deduplication, flexible access control, and multi-format package support.

Tech Stack

• Backend: Python 3.12 + FastAPI
• Frontend: React 18 + TypeScript + Vite
• Database: PostgreSQL 16
• Object Storage: MinIO (S3-compatible)
• Cache: Redis (for future use)

Features

Currently Implemented

• Content-Addressable Storage - Artifacts are stored and referenced by their SHA256 hash, ensuring deduplication and data integrity
• Project/Package/Artifact Hierarchy - Organized storage structure:
  • Project - Top-level organizational container
  • Package - Named collection within a project
  • Artifact - Specific content instance identified by SHA256
• Tags - Alias system for referencing artifacts by human-readable names (e.g., v1.0.0, latest, stable)
• Package Formats & Platforms - Packages can be tagged with format (npm, pypi, docker, deb, rpm, etc.) and platform (linux, darwin, windows, etc.)
• Rich Package Metadata - Package listings include aggregated stats (tag count, artifact count, total size, latest tag)
• S3-Compatible Backend - Uses MinIO (or any S3-compatible storage) for artifact storage
• PostgreSQL Metadata - Relational database for metadata, access control, and audit trails
• REST API - Full HTTP API for all operations
• Web UI - React-based interface for managing artifacts with:
  • Hierarchical navigation (Projects → Packages → Tags/Artifacts)
  • Search, sort, and filter capabilities on all list views
  • URL-based state persistence for filters and pagination
  • Keyboard navigation (Backspace to go up hierarchy)
  • Copy-to-clipboard for artifact IDs
  • Responsive design for mobile and desktop
• Docker Compose Setup - Easy local development environment
• Helm Chart - Kubernetes deployment with PostgreSQL, MinIO, and Redis subcharts
• Multipart Upload - Automatic multipart upload for files larger than 100MB
• Resumable Uploads - API for resumable uploads with part-by-part upload support
• Range Requests - HTTP range request support for partial downloads
• Format-Specific Metadata - Automatic extraction of metadata from package formats:
  • .deb - Debian packages (name, version, architecture, maintainer)
  • .rpm - RPM packages (name, version, release, architecture)
  • .tar.gz/.tgz - Tarballs (name, version from filename)
  • .whl - Python wheels (name, version, author)
  • .jar - Java JARs (manifest info, Maven coordinates)
  • .zip - ZIP files (file count, uncompressed size)

  -F "file=@./build/app-v1.0.0.tar.gz" \
  -F "tag=v1.0.0"

  "format_metadata": {
    "format": "tarball",
    "package_name": "app",
    "version": "1.0.0"
  },
  "deduplicated": false
}

Resumable Upload (for large files)

For files larger than 100MB, use the resumable upload API:

# 1. Initialize upload (client must compute SHA256 hash first)
curl -X POST http://localhost:8080/api/v1/project/my-project/releases/upload/init \
  -H "Content-Type: application/json" \
  -d '{
    "expected_hash": "a3f5d8e12b4c67890abcdef1234567890abcdef1234567890abcdef12345678",
    "filename": "large-file.tar.gz",
    "size": 524288000,
    "tag": "v2.0.0"
  }'

# Response: {"upload_id": "abc123", "already_exists": false, "chunk_size": 10485760}

# 2. Upload parts (10MB chunks recommended)
curl -X PUT http://localhost:8080/api/v1/project/my-project/releases/upload/abc123/part/1 \
  --data-binary @chunk1.bin

# 3. Complete the upload
curl -X POST http://localhost:8080/api/v1/project/my-project/releases/upload/abc123/complete \
  -H "Content-Type: application/json" \
  -d '{"tag": "v2.0.0"}'

Download an Artifact

# By tag (use -OJ to save with the correct filename from Content-Disposition header)
curl -OJ http://localhost:8080/api/v1/project/my-project/releases/+/v1.0.0

# By artifact ID
curl -OJ http://localhost:8080/api/v1/project/my-project/releases/+/artifact:a3f5d8e12b4c6789...

# Using the short URL pattern
curl -OJ http://localhost:8080/project/my-project/releases/+/latest

# Save to a specific filename
curl -o myfile.tar.gz http://localhost:8080/api/v1/project/my-project/releases/+/v1.0.0

# Partial download (range request)
curl -H "Range: bytes=0-1023" http://localhost:8080/api/v1/project/my-project/releases/+/v1.0.0

# Check file info without downloading (HEAD request)
curl -I http://localhost:8080/api/v1/project/my-project/releases/+/v1.0.0

# Download with specific mode (presigned, redirect, or proxy)
curl "http://localhost:8080/api/v1/project/my-project/releases/+/v1.0.0?mode=proxy"

# Get presigned URL for direct S3 download
curl http://localhost:8080/api/v1/project/my-project/releases/+/v1.0.0/url

Note on curl flags:

• -O saves the file using the URL path as the filename (e.g., latest, v1.0.0)
• -J tells curl to use the filename from the Content-Disposition header (e.g., app-v1.0.0.tar.gz)
• -OJ combines both: download to a file using the server-provided filename
• -o <filename> saves to a specific filename you choose

Download Modes

Orchard supports three download modes, configurable via ORCHARD_DOWNLOAD_MODE or per-request with ?mode=:

Mode	Description	Use Case
presigned (default)	Returns JSON with a presigned S3 URL	Clients that handle redirects themselves, web UIs
redirect	Returns HTTP 302 redirect to presigned S3 URL	Simple clients, browsers, wget
proxy	Streams content through the backend	When S3 isn't directly accessible to clients

Presigned URL Response:

{
  "url": "https://minio.example.com/bucket/...",
  "expires_at": "2025-01-01T01:00:00Z",
  "method": "GET",
  "artifact_id": "a3f5d8e...",
  "size": 1048576,
  "content_type": "application/gzip",
  "original_name": "app-v1.0.0.tar.gz",
  "checksum_sha256": "a3f5d8e...",
  "checksum_md5": "d41d8cd..."
}

Note: For presigned URLs to work, clients must be able to reach the S3 endpoint directly. In Kubernetes, this requires exposing MinIO via ingress (see Helm configuration below).

Create a Tag

curl -X POST http://localhost:8080/api/v1/project/my-project/releases/tags \
  -H "Content-Type: application/json" \
  -d '{"name": "stable", "artifact_id": "a3f5d8e12b4c6789..."}'

curl http://localhost:8080/api/v1/project/my-project/releases/tags

# With pagination
curl "http://localhost:8080/api/v1/project/my-project/releases/tags?page=1&limit=10"

# Search by tag name
curl "http://localhost:8080/api/v1/project/my-project/releases/tags?search=v1"

# Sort by created_at descending
curl "http://localhost:8080/api/v1/project/my-project/releases/tags?sort=created_at&order=desc"

    }
  ],

      "original_name": "app-v1.0.0.tar.gz",
      "created_at": "2025-01-01T00:00:00Z",
      "created_by": "user",
      "format_metadata": {},
      "tags": ["v1.0.0", "latest", "stable"]
    }
  ],
  "pagination": {"page": 1, "limit": 20, "total": 1, "total_pages": 1}
}

Kubernetes Deployment

Using Helm

# Add Bitnami repo for dependencies
helm repo add bitnami https://charts.bitnami.com/bitnami

# Update dependencies
cd helm/orchard
helm dependency update

# Install
helm install orchard ./helm/orchard -n orchard --create-namespace

# Install with custom values
helm install orchard ./helm/orchard -f my-values.yaml

Helm Configuration

Key configuration options in values.yaml:

orchard:
  # Download configuration
  download:
    mode: "presigned"       # presigned, redirect, or proxy
    presignedUrlExpiry: 3600

# MinIO ingress (required for presigned URL downloads)
minioIngress:
  enabled: true
  className: "nginx"
  annotations:
    cert-manager.io/cluster-issuer: "letsencrypt"
  host: "minio.your-domain.com"
  tls:
    enabled: true
    secretName: minio-tls

When minioIngress.enabled is true, the S3 endpoint automatically uses the external URL (https://minio.your-domain.com), making presigned URLs accessible to external clients.

See helm/orchard/values.yaml for all configuration options.
