-# 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
-

-## 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.

-
-### DNS resolution
-
-The main limitation of this setup is that containers can't find each other by name across machines. You need to use
-their IP addresses directly or implement a service discovery solution like Consul or CoreDNS.
-
-For small deployments, you can assign static IPs to containers and use those IPs in your app configuration. But service
-discovery is essential for larger and more dynamic deployments.
-
-### NAT traversal constraints
-
-For WireGuard connections to work, at least one machine in each pair must be publicly reachable. The connection fails if
-both machines are behind NAT. While solutions exist (STUN/TURN servers, UDP hole punching), they're beyond the scope of
-this guide.
-
-Common scenarios that work:
-
-- ✅ Cloud VPS (public or private IP) ↔ Cloud VPS (public or private IP). Both can use private IPs only if they're in the
-  same cloud provider's network
-- ✅ Homelab (behind NAT) ↔ Cloud VPS (public IP)
-- ✅ Homelab (private IP) ↔ Homelab (private IP on the same local network)

-Beyond the network setup, you also get:
-
-- Multi-machine [Docker Compose](https://docs.docker.com/reference/compose-file/) deployments with zero downtime.
-- Built-in DNS server that resolves container IPs by their service names.
-- Automatic HTTPS and reverse proxy configuration.
-
-Check out the [documentation](https://uncloud.run/docs) for more information.
 
 ## Alternative solutions
 
-Before settling on the WireGuard approach, I evaluated several alternatives. Note that I only considered lightweight
+//I wanted to explore only lightweight solutions for Docker so not talking about Kubernetes and a numerous CNI
-solutions suitable for Docker. Kubernetes and its CNI ecosystem deserve a separate discussion.
+//drivers. Let's leave this beast for another time.
 
 ### Docker Swarm overlay network
 
-Docker Swarm includes built-in [overlay networking](https://docs.docker.com/engine/network/drivers/overlay/). However,
-to use an overlay network, you need to run a [Swarm cluster](https://docs.docker.com/engine/swarm/) on all machines.
-This introduces additional complexity:
-
-- Cluster nodes must
-  [maintain the quorum](https://docs.docker.com/engine/swarm/admin_guide/#maintain-the-quorum-of-managers). Losing
-  quorum impacts the functionality of overlay networks.
-- Ports 2377, 7946, and 4789 must be exposed to untrusted networks (if connecting machines over the internet) for
-  cluster management, node communication, and VXLAN overlay traffic.
-- VXLAN traffic is unencrypted by default, requiring additional
-  [hardening](https://docs.docker.com/engine/swarm/swarm-tutorial/#open-protocols-and-ports-between-the-hosts) with
-  IPSec and firewalls.
-- Every node must be publicly reachable. VXLAN fails if machines are behind NAT.
-
-If these limitations are acceptable, an overlay network is a great option. Note that you can use an overlay network with
-regular containers without using any other Swarm features.
-
 ### Flannel
 
-[Flannel](https://github.com/flannel-io/flannel) is battle-tested in Kubernetes but can also be used with Docker. It
-supports multiple [backends](https://github.com/flannel-io/flannel/blob/master/Documentation/backends.md) including
-VXLAN and WireGuard.
-
-The main caveat is that Flannel requires running etcd as the datastore for coordination. Depending on your availability
-requirements, you may need to set up an etcd cluster with multiple nodes. This is not a problem if you're already using
-Kubernetes. But if you're just running a few Docker hosts, it might seem like overkill.
-
 ### Tailscale
 
-[Tailscale](https://tailscale.com/) makes WireGuard easy with automatic NAT traversal and key management, but it's not

+//machines. Maybe the subnet router feature can be used to connect Docker networks in a similar I described here, but
-
+//I haven't tested it.
-The recommended approach for using [Tailscale with Docker](https://tailscale.com/kb/1282/docker) is to connect each
-individual container to a Tailscale network. This means deploying an additional Tailscale container alongside every
-application container.
-
-Tailscale's [subnet router](https://tailscale.com/kb/1019/subnets) feature might work to expose Docker networks similar
-to our setup, but I haven't tested this approach.
