# AI.md - Uncloud Project Guide
This document provides comprehensive information about the Uncloud project for AI assistants to understand the codebase, architecture, and development practices.
## Project Overview
**Uncloud** is a lightweight clustering and container orchestration tool that enables deployment and management of web applications across cloud VMs and bare metal servers. It creates a secure WireGuard mesh network between Docker hosts and provides automatic service discovery, load balancing, HTTPS ingress, and simple CLI commands for application management.
### Key Characteristics
- **Language**: Go
- **Architecture**: Decentralized, no control plane
- **Target**: Self-hosted infrastructure without Kubernetes complexity
- **License**: View LICENSE file for details
- **Status**: Active development, not yet ready for production
## Core Features
### 🏗️ Infrastructure
- **Multi-machine deployment**: Combine cloud VMs, dedicated servers, and bare metal
- **Zero-config networking**: Automatic WireGuard mesh with NAT traversal
- **Decentralized design**: No central control plane, all machines are equal
- **Service discovery**: Built-in DNS server resolves service names to container IPs
### 🚀 Application Management
- **Docker Compose compatibility**: Uses familiar Docker Compose format
- **Zero-downtime deployments**: Rolling updates without service interruption
- **Automatic HTTPS**: Caddy reverse proxy with Let's Encrypt integration
- **Managed DNS**: Free `*.cluster.uncloud.run` subdomains via Uncloud DNS service
- **Cross-machine scaling**: Run containers across multiple machines
### 🔧 Developer Experience
- **Docker-like CLI**: Familiar commands (`uc` binary)
- **Imperative operations**: Direct commands vs. declarative state reconciliation
- **Remote management**: Control entire infrastructure via SSH to any machine
- **Minimal overhead**: ~150MB RAM footprint per machine
## Architecture
### Core Components
1. **CLI (`uc`)** - Main user interface for cluster management
2. **Daemon (`uncloudd`)** - Machine daemon running on each node
3. **Corrosion** - Distributed SQLite database for cluster state (Fly.io project)
4. **Caddy** - Reverse proxy for HTTPS termination and routing
5. **WireGuard** - Secure mesh networking between machines
### Network Architecture
- Each machine gets unique subnet (e.g., `10.210.0.0/24`, `10.210.1.0/24`)
- Containers get cluster-unique IPs for direct communication
- Automatic peer discovery and key management
- NAT traversal for machines behind firewalls
### State Management
- **CRDT-based distributed storage** using Corrosion
- **Eventually consistent** state across all machines
- **Gossip protocol** (Serf) for state propagation
- **No quorum requirements** - partial network splits remain functional
## Project Structure
### Key Directories
- **`cmd/`**: Contains main applications
- `uncloud/`: CLI tool with subcommands for machine, service, volume management
- `uncloudd/`: Daemon that runs on each machine
- `ucind/`: Development cluster management for testing
- **`internal/`**: Internal implementation packages
- `cli/`: Command-line interface logic
- `machine/`: Machine lifecycle and state management
- `daemon/`: Daemon implementation and gRPC services
- `dns/`: Internal DNS server for service discovery
- **`pkg/`**: Public API packages for external use
- `api/`: Core API types and definitions
- `client/`: Client libraries for interacting with Uncloud
- **`experiment/`**: Experimental features and prototypes
- **`scripts/`**: Installation and utility scripts
- **`test/`**: Test suites and test infrastructure
- **`website/`**: Documentation website (Docusaurus)
- **`misc/`**: Design documents and guides
## Key Technologies
### Core Dependencies
```go
// Networking and orchestration
github.com/docker/docker // Docker API client
github.com/docker/compose/v2 // Docker Compose integration
golang.zx2c4.com/wireguard // WireGuard implementation
github.com/hashicorp/serf // Gossip protocol
// State management
github.com/ipfs/go-ds-crdt // CRDT distributed storage

github.com/charmbracelet/huh // Interactive forms
// gRPC and networking
google.golang.org/grpc // gRPC framework
github.com/siderolabs/grpc-proxy // gRPC proxy for forwarding
```
## Development Workflow
### Build and Development
```bash
# Build binaries
go build -o uncloud ./cmd/uncloud
go build -o uncloudd ./cmd/uncloudd
```
### Key Make Targets
- `proto`: Generate protobuf code
- `ucind-cluster`: Create development cluster
- `update-dev`: Deploy to development machines
- `demo-reset`: Reset demo environment
- `fmt`: Format code
- `test`: Run all tests
- `lint`: Lint the code using golangci-lint
- `lint-and-fix`: Lint the code and fix issues whenever possible
## CLI Commands Structure
The `uc` CLI provides these main command groups:
### Machine Management
```bash
uc machine init <user@host> # Initialize new cluster
uc machine add <user@host> # Add machine to cluster
uc machine ls # List machines
uc machine rm <name> # Remove machine
```
### Service Management
```bash
uc run <image> # Run container from image
uc deploy # Deploy from compose.yaml
uc scale <service> <count> # Scale service replicas
uc ls # List services
uc rm <service> # Remove service
```
### Context and Connectivity
```bash
uc context ls # List available contexts
uc context use <name> # Switch context
```
### Global Flags
- `--connect`: Connect to remote machine directly, without a config file
- `--uncloud-config`: Override config file path
## Development Guidelines
### Code Organization
- **Package naming**: Use clear, descriptive names
- **Error handling**: Wrap errors with context using `fmt.Errorf`
- **Logging**: Use structured logging with levels
- **gRPC**: Services defined in `internal/machine/api/pb/`
### Testing
- Unit tests alongside source files (`*_test.go`)
- Integration tests in `test/e2e/`
- Test fixtures in `test/fixtures/`
### Dependencies
- Prefer standard library when possible
- Pin versions in `go.mod`
- Document rationale for external dependencies
### Configuration
- Support environment variables for key settings
- Validate configuration early
- Provide sensible defaults
## Troubleshooting and Debugging
### Common Issues
- **Networking**: Check WireGuard status, iptables rules
- **DNS**: Verify service discovery resolution
- **Containers**: Use standard Docker debugging tools
- **State sync**: Check Corrosion logs for replication issues
### Debugging Tools
- Standard Linux networking tools (`ping`, `traceroute`, `wireshark`)
- Docker commands (`docker ps`, `docker logs`)
- SSH access to machines for direct inspection
- gRPC debugging tools
### Logs and Monitoring
- Systemd services (getting logs via `journalctl -u SERVICE_NAME`)
- `uncloud` -- Uncloud daemon
- `uncloud-corrosion` -- Corrosion process
- Machine daemon logs
- Container logs via Docker
## File Patterns and Conventions
### Important Files to Understand
- `cmd/uncloud/main.go`: CLI entry point and command structure
- `internal/cli/cli.go`: CLI implementation and configuration
- `internal/machine/machine.go`: Core machine management
- `pkg/api/`: Public API definitions
- `misc/design.md`: Architecture and design philosophy
- `README.md`: User-facing documentation
### Configuration Files
- `go.mod/go.sum`: Go dependency management
- `Makefile`: Build and development tasks
- `Dockerfile`: Container build instructions forUncloud-in-Docker (used for testing)
This document should help AI assistants understand the project structure, make informed suggestions, and contribute effectively to the Uncloud codebase.

## 🎬 Quick demo
The screenshot below demonstrates how I use Uncloud to deploy https://uncloud.run website to 2 remote machines from
the [`compose.yaml`](website/compose.yaml) file on my local machine.
It exposes the container port `8000/tcp` as HTTPS on the domain `uncloud.run`, served by the Caddy reverse proxy on the
remote machines. All managed by Uncloud.

## 🙏 Inspiration & Acknowledgements
I'm grateful to the following projects that inspired Uncloud's design and implementation:
* [Kamal](https://kamal-deploy.org/) — for proving that even in the declarative era of Kubernetes there is a place for
simple deployment tools that use imperative commands without complex orchestration. Kamal powers the multi-billion
dollar company [37signals](https://37signals.com/) where it was created, and that's truly inspiring!
* [Fly.io](https://fly.io/) — for inspiring my vision for what self-hosted infrastructure should feel like, proving that
developer experience and powerful infrastructure can coexist beautifully.
* [Tailscale](https://tailscale.com/) — for pioneering the vision of decentralised flat mesh networking with an amazing

# Website
This website is built using [Docusaurus](https://docusaurus.io/), a modern static website generator.
### Installation
```
$ yarn
```
### Local Development
```
$ yarn start
```
This command starts a local development server and opens up a browser window. Most changes are reflected live without having to restart the server.
### Build
```
$ yarn build
```
This command generates static content into the `build` directory and can be served using any static contents hosting service.
### Deployment
Using SSH:
```
$ USE_SSH=true yarn deploy
```
Not using SSH:
```
$ GIT_USER=<Your GitHub username> yarn deploy
```
If you are using GitHub pages for hosting, this command is a convenient way to build the website and push to the `gh-pages` branch.
