-# 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
-

-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/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`: 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/uncloud
-```
-
-Or build and run the CLI with a single command:
-
-```shell
-go run ./cmd/uncloud --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
-```

+# WireGuard overlay network for Docker containers
 
-You want your Docker containers to talk to each other, but they're running on different machines. Perhaps across
-different cloud providers or mixing cloud with on-prem. The usual approach of mapping services to host ports quickly
-becomes a pain. Worse, if they're on the public internet, you need to secure every exposed endpoint with TLS and auth.
+# How to connect Docker containers across multiple hosts using WireGuard
 
-What if your containers on different machines could communicate directly without exposing any ports? Using their private
-Docker IPs, as if they were on the same machine. Here's how you can use pure WireGuard and some clever networking tricks
-to make this work.
+# Connect Docker containers across multiple hosts with WireGuard
+
+You have Docker containers running on different Linux machines. You want container A on one machine to talk directly to
+container B on another machine using their private IPs. For example, to run your application and database containers on
+separate machines without exposing them publicly. Here's how you can use pure WireGuard and some networking tricks to
+make this work.
+
+I implemented this technique to enable cross-machine container communication in
+[Uncloud](https://github.com/psviderski/uncloud), an open source clustering and deployment tool for Docker.

 ## What we're building
 
 Docker containers are typically connected to a [bridge network](https://docs.docker.com/engine/network/drivers/bridge/)
 on their host machine, which allows them to communicate with each other. A bridge network also provides isolation from

 local bridge network.
 
 The incantation we need is called a site-to-site VPN. Any solution would work. Moreover, if the machines are on the same
-local network, they're already connected and only lack the appropriate routing configuration. But I'll describe a more

-## Limitations
-
-### 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.

-  same cloud provider's network

+//I built Uncloud to handle all the heavy lifting automatically.
 
-I built [Uncloud](https://github.com/psviderski/uncloud), an open source clustering and deployment tool for Docker, to
-handle all the heavy lifting automatically. You can get the same result and much more with just a few commands.
-
-Initialise a new cluster on your first machine:
+You can initialise a cluster of machines by running the following commands:
 
 ```shell
-uc machine init user@machine1
+uc machine init user@machine1-ip
+uc machine add user@machine2-ip
+...
+uc machine add user@machineN-ip
 ```
 
-Add more machines to the cluster:
+//This will create `uncloud` Docker bridge network on each machine with `10.210.N.0/24` subnet by default and set up
+//WireGuard mesh network between them and make persistent across reboots.
 
-```shell
-uc machine add user@machine2
-uc machine add user@machine3
-```
-
-This is what these commands do:
-
-- Create the `uncloud` Docker network on each machine with unique subnets (`10.210.0.0/24`, `10.210.1.0/24`, etc.).
-- Generate WireGuard key pairs and distribute public keys across machines.
-- Start a full mesh WireGuard network.
-- Configure iptables rules for container communication.
-- Make everything persistent across reboots.
-
-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.
+//Mention embedded DNS that resolves container IPs by their service names and multi-machine Docker Compose support.
 
 ## Alternative solutions
 
-Before settling on the WireGuard approach, I evaluated several alternatives. Note that I only considered lightweight
-solutions suitable for Docker. Kubernetes and its CNI ecosystem deserve a separate discussion.
+//I wanted to explore only lightweight solutions for Docker so not talking about Kubernetes and a numerous CNI
+//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
-designed as a generic site-to-site VPN for connecting networks. Instead, it connects individual devices and provides
-identity-based access controls.
-
-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.
+//Not a generic site-to-site VPN, so the recommended approach is to use Tailscale on the container level. This way a
+//container that needs to talk across machines is configured as a Tailscale machine so it can connect to other Tailscale
+//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.
 
 ## Conclusion
 
-That's it! Now you know how to securely connect Docker containers across multiple machines using WireGuard. The manual
-setup works great for a handful of machines that you don't need to change often, but configuration management becomes
-tedious as you scale.
+//Summarise what we've done.?

-You can follow [this tutorial](https://labs.iximiuz.com/tutorials/uncloud-create-cluster-ebebf72b) which walks you through creating a new cluster with two machines and then deploying a simple web service to it.
-
-You can also launch the [Uncloud playground](https://labs.iximiuz.com/playgrounds/uncloud-cluster-64523f7c) where you can play with an already initialized Uncloud cluster.

-⏳ Stopping systemd services...
-Removed "/etc/systemd/system/multi-user.target.wants/uncloud.service".
-The unit files have no installation config (WantedBy=, RequiredBy=, UpheldBy=,
-Also=, or Alias= settings in the [Install] section, and DefaultInstance= for
-template units). This means they are not meant to be enabled or disabled using systemctl.
-
-Possible reasons for having these kinds of units are:
-• A unit may be statically enabled by being symlinked from another unit's
-  .wants/, .requires/, or .upholds/ directory.
-• A unit's purpose may be to act as a helper for some other unit which has
-  a requirement dependency on it.
-• A unit may be started when needed via activation (socket, path, timer,
-  D-Bus, udev, scripted systemctl call, ...).
-• In case of template units, the unit is meant to be enabled with some
-  instance name specified.
