A lightweight Git server supporting both HTTP and SSH protocols with multiple storage backends.

• HTTP Git Server: Full Git Smart HTTP protocol support

  • Clone, push, pull operations via HTTP/HTTPS
  • REST API for repository management
  • Graceful shutdown handling

• SSH Git Server: Custom SSH implementation for Git operations

  • Clone, push, pull operations via SSH
  • Public key and password authentication
  • Git protocol over SSH (git-upload-pack, git-receive-pack)

• Storage Backends:

  • Local: File system storage for repositories
  • S3: Amazon S3 compatible storage (tested and working)

• Configuration:

  • YAML configuration files
  • Command-line flags
  • Environment variable support

• Authentication:

  • Demo mode (password: "demo", accepts any SSH key)
  • Extensible authentication framework

• Logging: Structured logging with zerolog

• Parallel Servers: HTTP and SSH servers run concurrently
• Graceful Shutdown: CTRL+C handling with 30-second timeout
• Storage Abstraction: Pluggable storage backend system
• Transport Abstraction: Unified Git transport layer

Copy the example configuration:

cp config-example.yaml config.yaml

Edit config.yaml to configure your storage backend and server settings.

# Build the application
make build
# Run with default configuration
./main
# Or run with custom config
./main --config ./config.yaml

HTTP Access:

# Clone via HTTP
git clone http://localhost:8080/your-repo.git
# Push to HTTP
git push origin main

SSH Access: Not stable

# Clone via SSH (demo password: "demo")
git clone ssh://demo@localhost:2022/your-repo.git
# Push via SSH
git push origin main

• server.http.enabled: Enable/disable HTTP server
• server.http.port: HTTP server port (default: 8080)
• server.ssh.enabled: Enable/disable SSH server
• server.ssh.port: SSH server port (default: 2022)
• server.ssh.hostkey: Path to SSH host key file

• storage.type: Storage backend ("local" or "s3")
• storage.local.path: Local storage directory
• storage.s3.*: S3 configuration options

• Client Warning: Git clients may show "remote end hung up unexpectedly" message
  • Impact: Cosmetic only - all operations complete successfully
  • Status: Under investigation - server-side operations work perfectly
  • Workaround: Message can be safely ignored

• S3 Storage: Slower than local storage due to network latency
  • Expected: Normal behavior for remote storage
  • Optimization: Consider using S3 transfer acceleration

• Multi-user authentication system
• Role-based access control (RBAC)
• JWT token authentication
• LDAP/Active Directory integration
• Rate limiting and DDoS protection

• Azure Blob Storage backend
• Google Cloud Storage backend
• Redis caching layer
• Repository compression and deduplication

• Web UI for repository browsing
• Webhook support for CI/CD integration
• Branch protection rules
• Repository mirroring
• Git LFS (Large File Storage) support

• Metrics and monitoring (Prometheus)
• Health check endpoints
• Docker containerization
• Kubernetes deployment manifests
• Backup and restore tools

• Git protocol v2 support
• HTTP/2 support
• TLS certificate management
• SSH key management interface
