docs: Clarify pull/build comments in migration

After pulling images, also run build for services with Dockerfiles.
This ensures build-based services have their images ready before
stopping the old service, minimizing downtime.

If build fails, abort the migration and leave the service running
on the old host.

Extract _migrate_service helper to reduce function complexity.

-# Compose Farm – Traefik Multihost Ingress Plan
-
-## Goal
-Generate a Traefik file-provider fragment from existing docker-compose Traefik labels (no config duplication) so a single front-door Traefik on 192.168.1.66 with wildcard `*.lab.mydomain.org` can route to services running on other hosts. Keep the current simplicity (SSH + docker compose); no Swarm/K8s.
-
-## Requirements
-- Traefik stays on main host; keep current `dynamic.yml` and Docker provider for local containers.
-- Add a watched directory provider (any path works) and load a generated fragment (e.g., `compose-farm.generated.yml`).
-- No edits to compose files: reuse existing `traefik.*` labels as the single source of truth; Compose Farm only reads them.
-- Generator infers routing from labels and reachability from `ports:` mappings; prefer host-published ports so Traefik can reach services across hosts. Upstreams point to `<host address>:<published host port>`; warn if no published port is found.
-- Only minimal data in `compose-farm.yaml`: hosts map and service→host mapping (already present).
-- No new orchestration/discovery layers; respect KISS/YAGNI/DRY.
-
-## Non-Goals
-- No Swarm/Kubernetes adoption.
-- No global Docker provider across hosts.
-- No health checks/service discovery layer.
-
-## Current State (Dec 2025)
-- Compose Farm: Typer CLI wrapping `docker compose` over SSH; config in `compose-farm.yaml`; parallel by default; snapshot/log tooling present.
-- Traefik: single instance on 192.168.1.66, wildcard `*.lab.mydomain.org`, Docker provider for local services, file provider via `dynamic.yml` already in use.
-
-## Proposed Implementation Steps
-1) Add generator command: `compose-farm traefik-file --output <path>`.
-2) Resolve per-service host from `compose-farm.yaml`; read compose file at `{compose_dir}/{service}/docker-compose.yml`.
-3) Parse `traefik.*` labels to build routers/services/middlewares as in compose; map container port to published host port (from `ports:`) to form upstream URLs with host address.
-4) Emit file-provider YAML to the watched directory (recommended default: `/mnt/data/traefik/dynamic.d/compose-farm.generated.yml`, but user chooses via `--output`).
-5) Warnings: if no published port is found, warn that cross-host reachability requires L3 reachability to container IPs.
-6) Tests: label parsing, port mapping, YAML render; scenario with published port; scenario without published port.
-7) Docs: update README/CLAUDE to describe directory provider flags and the generator workflow; note that compose files remain unchanged.
-
-## Open Questions
-- How to derive target host address: use `hosts.<name>.address` verbatim, or allow override per service? (Default: use host address.)
-- Should we support multiple hosts/backends per service for LB/HA? (Start with single server.)
-- Where to store generated file by default? (Default to user-specified `--output`; maybe fallback to `./compose-farm-traefik.yml`.)

+I used to run 100+ Docker Compose stacks on a single machine that kept running out of memory. I needed a way to distribute services across multiple machines without the complexity of:
 
 - **Kubernetes**: Overkill for my use case. I don't need pods, services, ingress controllers, or YAML manifests 10x the size of my compose files.
 - **Docker Swarm**: Effectively in maintenance mode—no longer being invested in by Docker.
 
-**Compose Farm is intentionally simple**: one YAML config mapping services to hosts, and a CLI that runs `docker compose` commands over SSH. That's it.
+Both require changes to your compose files. **Compose Farm requires zero changes**—your existing `docker-compose.yml` files work as-is.
+
+I also wanted a declarative setup—one config file that defines where everything runs. Change the config, run `up`, and services migrate automatically. See [Comparison with Alternatives](#comparison-with-alternatives) for how this compares to other approaches.

+<a href="https://xkcd.com/927/">
+<img src="https://imgs.xkcd.com/comics/standards.png" alt="xkcd: Standards" width="400" />
+</a>
+</p>
+
+Before you say it—no, this is not a new standard. I changed nothing about my existing setup. When I added more hosts, I just mounted my drives at the same paths, and everything worked. You can do all of this manually today—SSH into a host and run `docker compose up`.
+
+Compose Farm just automates what you'd do by hand:
+- Runs `docker compose` commands over SSH
+- Tracks which service runs on which host
+- Auto-migrates services when you change the host assignment
+- Generates Traefik file-provider config for cross-host routing
+
+**It's a convenience wrapper, not a new paradigm.**

@@ -128,14 +171,80 @@ services:
   jellyfin: server-2

+  autokuma: all              # Runs on ALL configured hosts

 ```
 
 Compose files are expected at `{compose_dir}/{service}/compose.yaml` (also supports `compose.yml`, `docker-compose.yml`, `docker-compose.yaml`).
 
+### Multi-Host Services
+
+Some services need to run on every host. This is typically required for tools that access **host-local resources** like the Docker socket (`/var/run/docker.sock`), which cannot be accessed remotely without security risks.
+
+Common use cases:
+- **AutoKuma** - auto-creates Uptime Kuma monitors from container labels (needs local Docker socket)
+- **Dozzle** - real-time log viewer (needs local Docker socket)
+- **Promtail/Alloy** - log shipping agents (needs local Docker socket and log files)
+- **node-exporter** - Prometheus host metrics (needs access to host /proc, /sys)
+
+This is the same pattern as Docker Swarm's `deploy.mode: global`.
+
+Use the `all` keyword or an explicit list:
+
+```yaml
+services:
+  # Run on all configured hosts
+  autokuma: all
+  dozzle: all
+
+  # Run on specific hosts
+  node-exporter: [server-1, server-2, server-3]
+```
+
+When you run `cf up autokuma`, it starts the service on all hosts in parallel. Multi-host services:
+- Are excluded from migration logic (they always run everywhere)
+- Show output with `[service@host]` prefix for each host
+- Track all running hosts in state
+
+### Config Command
+
+Compose Farm includes a `config` subcommand to help manage configuration files:
+
+```bash
+cf config init      # Create a new config file with documented example
+cf config show      # Display current config with syntax highlighting
+cf config path      # Print the config file path (useful for scripting)
+cf config validate  # Validate config syntax and schema
+cf config edit      # Open config in $EDITOR
+```
+
+Use `cf config init` to get started with a fully documented template.
+
 ## Usage
 
 The CLI is available as both `compose-farm` and the shorter `cf` alias.
 
+| Command | Description |
+|---------|-------------|
+| `cf up <svc>` | Start service (auto-migrates if host changed) |
+| `cf down <svc>` | Stop service |
+| `cf restart <svc>` | down + up |
+| `cf update <svc>` | pull + down + up |
+| `cf pull <svc>` | Pull latest images |
+| `cf logs -f <svc>` | Follow logs |
+| `cf ps` | Show status of all services |
+| `cf sync` | Discover running services + capture image digests |
+| `cf check` | Validate config, mounts, networks |
+| `cf init-network` | Create Docker network on hosts |
+| `cf traefik-file` | Generate Traefik file-provider config |
+| `cf config <cmd>` | Manage config files (init, show, path, validate, edit) |
+
+All commands support `--all` to operate on all services.
+
+Each command replaces: look up host → SSH → find compose file → run `ssh host "cd /opt/compose/plex && docker compose up -d"`.

+## Comparison with Alternatives
+
+There are many ways to run containers on multiple hosts. Here is where Compose Farm sits:
+
+| | Compose Farm | Docker Contexts | K8s / Swarm | Ansible / Terraform | Portainer / Coolify |
+|---|:---:|:---:|:---:|:---:|:---:|
+| No compose rewrites | ✅ | ✅ | ❌ | ✅ | ✅ |
+| Version controlled | ✅ | ✅ | ✅ | ✅ | ❌ |
+| State tracking | ✅ | ❌ | ✅ | ✅ | ✅ |
+| Auto-migration | ✅ | ❌ | ✅ | ❌ | ❌ |
+| Interactive CLI | ✅ | ❌ | ❌ | ❌ | ❌ |
+| Parallel execution | ✅ | ❌ | ✅ | ✅ | ✅ |
+| Agentless | ✅ | ✅ | ❌ | ✅ | ❌ |
+| High availability | ❌ | ❌ | ✅ | ❌ | ❌ |
+
+**Docker Contexts** — You can use `docker context create remote ssh://...` and `docker compose --context remote up`. But it's manual: you must remember which host runs which service, there's no global view, no parallel execution, and no auto-migration.
+
+**Kubernetes / Docker Swarm** — Full orchestration that abstracts away the hardware. But they require cluster initialization, separate control planes, and often rewriting compose files. They introduce complexity (consensus, overlay networks) unnecessary for static "pet" servers.
+
+**Ansible / Terraform** — Infrastructure-as-Code tools that can SSH in and deploy containers. But they're push-based configuration management, not interactive CLIs. Great for setting up state, clumsy for day-to-day operations like `cf logs -f` or quickly restarting a service.
+
+**Portainer / Coolify** — Web-based management UIs. But they're UI-first and often require agents on your servers. Compose Farm is CLI-first and agentless.
+
+**Compose Farm is the middle ground:** a robust CLI that productizes the manual SSH pattern. You get the "cluster feel" (unified commands, state tracking) without the "cluster cost" (complexity, agents, control planes).

 # Compose Farm Examples
 
-This folder contains example Docker Compose services for testing Compose Farm locally.
+Real-world examples demonstrating compose-farm patterns for multi-host Docker deployments.
+
+## Services
+
+| Service | Type | Demonstrates |
+|---------|------|--------------|
+| [traefik](traefik/) | Infrastructure | Reverse proxy, Let's Encrypt, file-provider |
+| [mealie](mealie/) | Single container | Traefik labels, resource limits, environment vars |
+| [uptime-kuma](uptime-kuma/) | Single container | Docker socket, user mapping, custom DNS |
+| [paperless-ngx](paperless-ngx/) | Multi-container | Redis + App stack (SQLite) |
+| [autokuma](autokuma/) | Multi-host | Demonstrates `all` keyword (runs on every host) |
+
+## Key Patterns
+
+### External Network
+
+All services connect to a shared external network for inter-service communication:
+
+```yaml
+networks:
+  mynetwork:
+    external: true
+```
+
+Create it on each host with consistent settings:
+
+```bash
+compose-farm init-network --network mynetwork --subnet 172.20.0.0/16
+```
+
+### Traefik Labels (Dual Routes)
+
+Services expose two routes for different access patterns:
+
+1. **HTTPS route** (`websecure` entrypoint): For your custom domain with Let's Encrypt TLS
+2. **HTTP route** (`web` entrypoint): For `.local` domains on your LAN (no TLS needed)
+
+This pattern allows accessing services via:
+- `https://mealie.example.com` - from anywhere, with TLS
+- `http://mealie.local` - from your local network, no TLS overhead
+
+```yaml
+labels:
+  # HTTPS route for custom domain (e.g., mealie.example.com)
+  - traefik.enable=true
+  - traefik.http.routers.myapp.rule=Host(`myapp.${DOMAIN}`)
+  - traefik.http.routers.myapp.entrypoints=websecure
+  - traefik.http.services.myapp.loadbalancer.server.port=8080
+  # HTTP route for .local domain (e.g., myapp.local)
+  - traefik.http.routers.myapp-local.rule=Host(`myapp.local`)
+  - traefik.http.routers.myapp-local.entrypoints=web
+```
+
+> **Note:** `.local` domains require local DNS (e.g., Pi-hole, Technitium) to resolve to your Traefik host.
+
+### Environment Variables
+
+Each service has a `.env` file for secrets and domain configuration.
+Edit these files to set your domain and credentials:
+
+```bash
+# Example: set your domain
+echo "DOMAIN=example.com" > mealie/.env
+```
+
+Variables like `${DOMAIN}` are substituted at runtime by Docker Compose.
+
+### NFS Volume Mounts
+
+All data is stored on shared NFS storage at `/mnt/data/`:
+
+```yaml
+volumes:
+  - /mnt/data/myapp:/app/data
+```
+
+This allows services to migrate between hosts without data loss.
+
+### Multi-Host Services
+
+Services that need to run on every host (e.g., monitoring agents):
+
+```yaml
+# In compose-farm.yaml
+services:
+  autokuma: all  # Runs on every configured host
+```
+
+### Multi-Container Stacks
+
+Database-backed apps with multiple services:
+
+```yaml
+services:
+  redis:
+    image: redis:7
+  app:
+    depends_on:
+      - redis
+```
+
+> **NFS + PostgreSQL Warning:** PostgreSQL should NOT run on NFS storage due to
+> fsync and file locking issues. Use SQLite (safe for single-writer on NFS) or
+> keep PostgreSQL data on local volumes (non-migratable).
+
+### AutoKuma Labels (Optional)
+
+The autokuma example demonstrates compose-farm's **multi-host feature** - running the same service on all hosts using the `all` keyword. AutoKuma itself is not part of compose-farm; it's just a good example because it needs to run on every host to monitor local Docker containers.
+
+[AutoKuma](https://github.com/BigBoot/AutoKuma) automatically creates Uptime Kuma monitors from Docker labels:
+
+```yaml
+labels:
+  - kuma.myapp.http.name=My App
+  - kuma.myapp.http.url=https://myapp.${DOMAIN}
+```
 
 ## Quick Start
 
 ```bash
 cd examples
 
-# Check status of all services
-compose-farm ps
+# 1. Create the shared network on all hosts
+compose-farm init-network
 
-# Pull images
-compose-farm pull --all
-
-# Start hello-world (runs and exits)
-compose-farm up hello
-
-# Start nginx (stays running)
-compose-farm up nginx
-
-# Check nginx is running
-curl localhost:8080
-
-# View logs
-compose-farm logs nginx
-
-# Stop nginx
-compose-farm down nginx
-
-# Update all (pull + restart)
-compose-farm update --all
-```
-
-## Traefik Example
-
-Start Traefik and a sample service with Traefik labels:
-
-```bash
-cd examples
-
-# Start Traefik (reverse proxy with dashboard)
+# 2. Start Traefik first (the reverse proxy)
 compose-farm up traefik
 
-# Start whoami (test service with Traefik labels)
-compose-farm up whoami
+# 3. Start other services
+compose-farm up mealie uptime-kuma
 
-# Access the services
-curl -H "Host: whoami.localhost" http://localhost    # whoami via Traefik
-curl http://localhost:8081                            # Traefik dashboard
-curl http://localhost:18082                           # whoami direct
+# 4. Check status
+compose-farm ps
 
-# Generate Traefik file-provider config (for multi-host setups)
+# 5. Generate Traefik file-provider config for cross-host routing
 compose-farm traefik-file --all
 
-# Stop everything
+# 6. View logs
+compose-farm logs mealie
+
+# 7. Stop everything
 compose-farm down --all
 ```
 
-The `whoami/docker-compose.yml` shows the standard Traefik label pattern:
+## Configuration
 
-```yaml
-labels:
-  - traefik.enable=true
-  - traefik.http.routers.whoami.rule=Host(`whoami.localhost`)
-  - traefik.http.routers.whoami.entrypoints=web
-  - traefik.http.services.whoami.loadbalancer.server.port=80
+The `compose-farm.yaml` shows a multi-host setup:
+
+- **primary** (192.168.1.10): Runs Traefik and heavy services
+- **secondary** (192.168.1.11): Runs lighter services
+- **autokuma**: Runs on ALL hosts to monitor local containers
+
+When Traefik runs on `primary` and a service runs on `secondary`, compose-farm
+automatically generates file-provider config so Traefik can route to it.
+
+## Traefik File-Provider
+
+When services run on different hosts than Traefik, use `traefik-file` to generate routing config:
+
+```bash
+# Generate config for all services
+compose-farm traefik-file --all -o traefik/dynamic.d/compose-farm.yml
+
+# Or configure auto-generation in compose-farm.yaml:
+traefik_file: /opt/stacks/traefik/dynamic.d/compose-farm.yml
+traefik_service: traefik
 ```
 
-## Services
-
-| Service | Description | Ports |
-|---------|-------------|-------|
-| hello | Hello-world container (exits immediately) | - |
-| nginx | Nginx web server | 8080 |
-| traefik | Traefik reverse proxy with dashboard | 80, 8081 |
-| whoami | Test service with Traefik labels | 18082 |
-
-## Config
-
-The `compose-farm.yaml` in this directory configures all services to run locally (no SSH).
-It also demonstrates the `traefik_file` option for auto-regenerating Traefik file-provider config.
+With `traefik_file` configured, compose-farm automatically regenerates the config after `up`, `down`, `restart`, and `update` commands.
