# AGENTS.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 `*.xxxxxx.uncld.dev` 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
- `uc/`: 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)
- `landing/`: Landing page
- `docs/`: User documentation
- **`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/dgraph-io/badger/v3 // Embedded database
// Web proxy
github.com/caddyserver/caddy/v2 // HTTP server and reverse proxy
// CLI and UX
github.com/spf13/cobra // CLI framework
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 uc ./cmd/uc
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
- Test files and locations
- Unit tests alongside source files (`*_test.go`)
- Integration tests in `test/e2e/`
- Test fixtures in `test/fixtures/`
- Use table driven tests whenever possible
- Use the `testify` library for assertions (e.g., `require.Equal`, `assert.Nil`)
### 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/uc/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`: Repository README
### 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.
## Documentation
Instructions when generating documentation:
- Use conversational language write as if you were speaking to a friend.
- Keep sentences simple, optimize for clarity and understanding.
- Do not use em dashes (—) or semicolons (;) in sentences. Instead, break complex sentences into simpler ones.
- Place the subject before the action whenever possible. Example: prefer "The function loads data" over "Data is loaded
by the function."

# Developing Uncloud
A short guide on setting up your local development environment.
## Prerequisites
- [mise](https://mise.jdx.dev/) (development environment setup tool)
- [Docker](https://docs.docker.com/get-docker/) with BuildKit (for running end-to-end tests). Make sure the
[`docker buildx`](https://docs.docker.com/build/concepts/overview/) plugin is installed.
## Setup
Uncloud uses `mise` to install and manage development tools and dependencies. It makes it easy to create reproducible
development environments on developer machines and CI.
Follow the [Installing Mise](https://mise.jdx.dev/installing-mise.html) guide to get it set up on your machine.
Mark the project as trusted and install all required tools (Go, `protoc`, `golangci-lint`, etc.) by running from the
project root:
```shell
mise trust
mise install
```
This reads [`mise.toml`](mise.toml) and installs the exact versions of tools specified there. They will be available in
your `PATH` when you are in the project directory, so you can run `go` or `golangci-lint` directly. The tools won't be
available outside the project, so they don't interfere with system packages.
## Building
Build the CLI:
```shell
go build -o uc ./cmd/uc
```
Or build and run the CLI with a single command:
```shell
go run ./cmd/uc --help
```
The Uncloud daemon (`uncloudd`) only supports Linux, so you need to cross-compile it if you're developing on macOS or
Windows:
```shell
GOOS=linux GOARCH=amd64 go build -o uncloudd ./cmd/uncloudd
```
## Testing
Run all tests (unit and e2e):
```shell
make test
```
### End-to-end tests
E2e tests run inside Docker using the [Uncloud-in-Docker](#uncloud-in-docker-ucind) image. Build it first:
```shell
mise ucind:image
```
⚠️ NOTE: You need to rebuild the `ucind` image every time you make changes to the daemon code if you want to test them
in e2e tests.
Then run the tests:
```shell
make test-e2e
```
If tests leave leftover containers, clean them up with:
```shell
make test-clean
```
### Manual testing on dev machines
After making changes to the daemon code, you may want to test them in your dev cluster. Build and install `uncloudd` on
one or multiple dev machines over SSH with:
```shell
mise run dev:install user@host1 user@host2/arm64
```
It will also restart the `uncloud.service` daemon on those machines to pick up the new version. The host format is
`[user@]host[/arch]`. The architecture of a machine defaults to `amd64` if not specified.
To stop the daemon and wipe all Uncloud data on the dev machines, run:
```shell
mise run dev:reset user@host1 user@host2
```
## Linting and formatting
Lint and format the code:
```shell
make lint-and-fix
```
## Code generation
Update the generated Go code for the machine gRPC API after modifying `.proto` files:
```shell
mise run proto
```
Regenerate mocks:
```shell
make mocks
```
## Uncloud in Docker (UCinD)
The [`ucind`](./cmd/ucind) CLI lets you run Uncloud clusters locally using Docker containers instead of real machines.
Each cluster machine runs as a Docker container connected to a shared Docker network.
Cluster machines use the `ghcr.io/psviderski/ucind:latest` Docker image by default. It may not always have the latest
changes to the `uncloudd` daemon code as it's not automatically rebuilt on CI yet.
You can rebuild it locally to pick up the latest changes, including your work in progress, and test them in a UCinD
cluster:
```shell
mise ucind:image
```
Create a cluster with 3 machines:
```shell
mise ucind cluster create -m 3
```
This also sets the new cluster as the active context, so you can interact with it using the `uc` CLI right away.
Remove the cluster when you're done:
```shell
mise ucind cluster rm
```
Sometimes crashed tests or interrupted runs can leave orphaned containers and networks behind. Clean them all up with:
```shell
mise ucind:cleanup
```

## 🏗 Project status
Uncloud is under active development and pre-1.0, so expect occasional breaking changes between releases. The core build,
push, and deploy workflows are stable, and much of the runtime relies on battle-tested projects: Docker, Caddy,
WireGuard, and Corrosion.
Uncloud is currently in active development and is **not ready for production use**. Features may change significantly
and there may be breaking changes between releases.

## 🙏 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
user experience that feels like magic.
* [Talos Linux](https://github.com/siderolabs/talos)
and [KubeSpan](https://www.talos.dev/v1.10/talos-guides/network/kubespan/) — for the machine API design using
[grpc-proxy](https://github.com/siderolabs/grpc-proxy) and for its elegant approach to secure WireGuard-based overlay
networking with zero configuration.
* [Docker Swarm Classic](https://github.com/docker-archive/classicswarm) and
[Rancher 1.x](http://rancher-com-website-main-elb-elb-1798790864.us-west-2.elb.amazonaws.com/docs/rancher/v1.6/en/)
— for showing the power of simplicity and pragmatism in container orchestration and that not every problem needs the
complexity of Kubernetes.
Special thanks to the [Corrosion](https://github.com/superfly/corrosion) project by Fly.io for providing the distributed
SQLite database used to share Uncloud's cluster state.

# 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.
