update: Only restart containers when images change (#143)

* update: Only restart containers when images change

Use `up -d --pull always --build` instead of separate pull/build/down/up
steps. This avoids unnecessary container restarts when images haven't
changed.

* Update README.md

* docs: Update update command description across all docs

Reflect new behavior: only recreates containers if images changed.

* Update README.md

+Review documentation for accuracy, completeness, and consistency. Focus on things that require judgment—automated checks handle the rest.
 
-## Scope
+## What's Already Automated
 
-Review all documentation files:
-- docs/*.md (primary documentation)
-- README.md (repository landing page)
-- CLAUDE.md (development guidelines)
-- examples/README.md (example configurations)
+Don't waste time on these—CI and pre-commit hooks handle them:
 
-## Review Checklist
+- **README help output**: `markdown-code-runner` regenerates `cf --help` blocks in CI
+- **README command table**: Pre-commit hook verifies commands are listed
+- **Linting/formatting**: Handled by pre-commit
 
-### 1. Command Documentation
+## What This Review Is For
 
-For each documented command, verify against the CLI source code:
+Focus on things that require judgment:
 
-- Command exists in codebase
-- All options are documented with correct names, types, and defaults
-- Short options (-x) match long options (--xxx)
-- Examples would work as written
-- Check for undocumented commands or options
+1. **Accuracy**: Does the documentation match what the code actually does?
+2. **Completeness**: Are there undocumented features, options, or behaviors?
+3. **Clarity**: Would a new user understand this? Are examples realistic?
+4. **Consistency**: Do different docs contradict each other?
+5. **Freshness**: Has the code changed in ways the docs don't reflect?
 
-Run `--help` for each command to verify.
+## Review Process
 
-### 2. Configuration Documentation
+### 1. Check Recent Changes
 
-Verify against Pydantic models in the config module:
+```bash
+# What changed recently that might need doc updates?
+git log --oneline -20 | grep -iE "feat|fix|add|remove|change|option"
 
-- All config keys are documented
-- Types match Pydantic field types
-- Required vs optional fields are correct
-- Default values are accurate
-- Config file search order matches code
-- Example YAML is valid and uses current schema
+# What code files changed?
+git diff --name-only HEAD~20 | grep "\.py$"
+```
 
-### 3. Architecture Documentation
+Look for new features, changed defaults, renamed options, or removed functionality.
 
-Verify against actual directory structure:
+### 2. Verify docs/commands.md Options Tables
 
-- File paths match actual source code location
-- All modules listed actually exist
-- No modules are missing from the list
-- Component descriptions match code functionality
-- CLI module list includes all command files
+The README auto-updates help output, but `docs/commands.md` has **manually maintained options tables**. These can drift.
 
-### 4. State and Data Files
+For each command's options table, compare against `cf <command> --help`:
+- Are all options listed?
+- Are short flags correct?
+- Are defaults accurate?
+- Are descriptions accurate?
 
-Verify against state and path modules:
+**Pay special attention to subcommands** (`cf config *`, `cf ssh *`)—these have their own options that are easy to miss.
 
-- State file name and location are correct
-- State file format matches actual structure
-- Log file name and location are correct
-- What triggers state/log updates is accurate
+### 3. Verify docs/configuration.md
 
-### 5. Installation Documentation
+Compare against Pydantic models in the source:
 
-Verify against pyproject.toml:
+```bash
+# Find the config models
+grep -r "class.*BaseModel" src/ --include="*.py" -A 15

-- Python version requirement matches requires-python
-- Package name is correct
-- Optional dependencies are documented
-- CLI entry points are mentioned
-- Installation methods work as documented
+Check:
+- All config keys documented
+- Types and defaults match code

+- Descriptions match what the code does
 
-Check for conflicts between documentation files:
+### 5. Check Examples
 
-- README vs docs/index.md (should be consistent)
-- CLAUDE.md vs actual code structure
-- Command tables match across files
-- Config examples are consistent
+For examples in any doc:
+- Would the YAML/commands actually work?
+- Are service names, paths, and options realistic?
+- Do examples use current syntax (not deprecated options)?
 
-### 8. Recent Changes Check

+- README.md vs docs/index.md
+- docs/commands.md vs CLAUDE.md command tables
+- Config examples across different docs
 
-- Run `git log --oneline -20` to see recent commits
-- Look for commits with `feat:`, `fix:`, or that mention new options/commands
-- Cross-reference these against the documentation to catch undocumented features

-
-- Run `uv run markdown-code-runner <file>` to regenerate outputs
-- Check for missing `<!-- OUTPUT:START -->` markers (blocks that never ran)

+# Duplication audit and generalization prompt
+
+You are a coding agent working inside a repository. Your job is to find duplicated
+functionality (not just identical code) and propose a minimal, safe generalization.
+Keep it simple and avoid adding features.
+
+## First steps
+
+- Read project-specific instructions (AGENTS.md, CONTRIBUTING.md, or similar) and follow them.
+- If instructions mention tooling or style (e.g., preferred search tools), use those.
+- Ask a brief clarification if the request is ambiguous (for example: report only vs refactor).
+
+## Objective
+
+Identify and consolidate duplicated functionality across the codebase. Duplication includes:
+- Multiple functions that parse or validate the same data in slightly different ways
+- Repeated file reads or config parsing
+- Similar command building or subprocess execution paths
+- Near-identical error handling or logging patterns
+- Repeated data transforms that can become a shared helper
+
+The goal is to propose a general, reusable abstraction that reduces duplication while
+preserving behavior. Keep changes minimal and easy to review.
+
+## Search strategy
+
+1) Map the hot paths
+- Scan entry points (CLI, web handlers, tasks, jobs) to see what they do repeatedly.
+- Look for cross-module patterns: same steps, different files.
+
+2) Find duplicate operations
+- Use fast search tools (prefer `rg`) to find repeated keywords and patterns.
+- Check for repeated YAML/JSON parsing, env interpolation, file IO, command building,
+  data validation, or response formatting.
+
+3) Validate duplication is real
+- Confirm the functional intent matches (not just similar code).
+- Note any subtle differences that must be preserved.
+
+4) Propose a minimal generalization
+- Suggest a shared helper, utility, or wrapper.
+- Avoid over-engineering. If only two call sites exist, keep the helper small.
+- Prefer pure functions and centralized IO if that already exists.
+
+## Deliverables
+
+Provide a concise report with:
+
+1) Findings
+- List duplicated behaviors with file references and a short description of the
+  shared functionality.
+- Explain why these are functionally the same (or nearly the same).
+
+2) Proposed generalizations
+- For each duplication, propose a shared helper and where it should live.
+- Outline any behavior differences that need to be parameterized.
+
+3) Impact and risk
+- Note any behavior risks, test needs, or migration steps.
+
+If the user asked you to implement changes:
+- Make only the minimal edits needed to dedupe behavior.
+- Keep the public API stable unless explicitly requested.
+- Add small comments only when the logic is non-obvious.
+- Summarize what changed and why.
+
+## Output format
+
+- Start with a short summary of the top 1-3 duplications.
+- Then provide a list of findings, ordered by impact.
+- Include a small proposed refactor plan (step-by-step, no more than 5 steps).
+- End with any questions or assumptions.
+
+## Guardrails
+
+- Do not add new features or change behavior beyond deduplication.
+- Avoid deep refactors without explicit request.
+- Preserve existing style conventions and import rules.
+- If a duplication is better left alone (e.g., clarity, single usage), say so.

+Update demo recordings to match the current compose-farm.yaml configuration.
+
+## Key Gotchas
+
+1. **Never `git checkout` without asking** - check for uncommitted changes first
+2. **Prefer `nas` stacks** - demos run locally on nas, SSH adds latency
+3. **Terminal captures keyboard** - use `blur()` to release focus before command palette
+4. **Clicking sidebar navigates away** - clicking h1 scrolls to top
+5. **Buttons have icons, not text** - use `[data-tip="..."]` selectors
+6. **`record.py` auto-restores config** - no manual cleanup needed after CLI demos
+
+## Stacks Used in Demos

+| `grocy` | update | navigation, stack, workflow, console | - |

+| `dozzle` | - | workflow | - |
+
+## CLI Demos
+
+**Files:** `docs/demos/cli/*.tape`
+
+Check:
+- `quickstart.tape`: `bat -r` line ranges match current config structure
+- `migration.tape`: nvim keystrokes work, stack exists on nas
+- `compose.tape`: exec commands produce meaningful output
+
+Run: `python docs/demos/cli/record.py [demo]`

+## Web Demos
+
+**Files:** `docs/demos/web/demo_*.py`

+- Stack names in demos still exist in config
+- Selectors match current templates (grep for IDs in `templates/`)
+- Shell demo uses command palette for ALL navigation

 A minimal CLI tool to run Docker Compose commands across multiple hosts via SSH.
 
 > [!NOTE]
-> Run `docker compose` commands across multiple hosts via SSH. One YAML maps stacks to hosts. Run `cf apply` and reality matches your config—stacks start, migrate, or stop as needed. No Kubernetes, no Swarm, no magic.
+> Agentless multi-host Docker Compose. CLI-first with a web UI. Your files stay as plain folders—version-controllable, no lock-in. Run `cf apply` and reality matches your config.
+
+**Why Compose Farm?**
+- **Your files, your control** — Plain folders + YAML, not locked in Portainer. Version control everything.
+- **Agentless** — Just SSH, no agents to deploy (unlike [Dockge](https://github.com/louislam/dockge)).
+- **Zero changes required** — Existing compose files work as-is.
+- **Grows with you** — Start single-host, scale to multi-host seamlessly.
+- **Declarative** — Change config, run `cf apply`, reality matches.

+## Host Resource Monitoring (Glances)
+
+The web UI can display real-time CPU, memory, and load stats for all configured hosts. This uses [Glances](https://nicolargo.github.io/glances/), a cross-platform system monitoring tool with a REST API.
+
+**Setup**
+
+1. Deploy a Glances stack that runs on all hosts:
+
+```yaml
+# glances/compose.yaml
+name: glances
+services:
+  glances:
+    image: nicolargo/glances:latest
+    container_name: glances
+    restart: unless-stopped
+    pid: host
+    ports:
+      - "61208:61208"
+    environment:
+      - GLANCES_OPT=-w  # Enable web server mode
+    volumes:
+      - /var/run/docker.sock:/var/run/docker.sock:ro
+```
+
+2. Add it to your config as a multi-host stack:
+
+```yaml
+# compose-farm.yaml
+stacks:
+  glances: all  # Runs on every host
+
+glances_stack: glances  # Enables resource stats in web UI
+```
+
+3. Deploy: `cf up glances`
+
+4. **(Docker web UI only)** If running the web UI in a Docker container, set `CF_LOCAL_HOST` to your local hostname in `.env`:
+
+```bash
+echo "CF_LOCAL_HOST=nas" >> .env  # Replace 'nas' with your local host name
+```
+
+This tells the web UI to reach the local Glances via container name instead of IP (required due to Docker network isolation).
+
+The web UI dashboard will now show a "Host Resources" section with live stats from all hosts. Hosts where Glances is unreachable show an error indicator.
+
+**Live Stats Page**
+
+With Glances configured, a Live Stats page (`/live-stats`) shows all running containers across all hosts:
+
+- **Columns**: Stack, Service, Host, Image, Status, Uptime, CPU, Memory, Net I/O
+- **Features**: Sorting, filtering, live updates (no SSH required—uses Glances REST API)
+

+# Docker Deployment
+
+Run the Compose Farm web UI in Docker.
+
+## Quick Start
+
+**1. Get the compose file:**
+
+```bash
+curl -O https://raw.githubusercontent.com/basnijholt/compose-farm/main/docker-compose.yml
+```
+
+**2. Generate `.env` file:**
+
+```bash
+cf config init-env -o .env
+```
+
+This auto-detects settings from your `compose-farm.yaml`:
+- `DOMAIN` from existing traefik labels
+- `CF_COMPOSE_DIR` from config
+- `CF_UID/GID/HOME/USER` from current user
+- `CF_LOCAL_HOST` by matching local IPs to config hosts
+
+Review the output and edit if needed.
+
+**3. Set up SSH keys:**
+
+```bash
+docker compose run --rm cf ssh setup
+```
+
+**4. Start the web UI:**
+
+```bash
+docker compose up -d web
+```
+
+Open `http://localhost:9000` (or `https://compose-farm.example.com` if using Traefik).
+
+---
+
+## Configuration
+
+The `cf config init-env` command auto-detects most settings. After running it, review the generated `.env` file and edit if needed:
+
+```bash
+$EDITOR .env
+```
+
+### What init-env detects
+
+| Variable | How it's detected |
+|----------|-------------------|
+| `DOMAIN` | Extracted from traefik labels in your stacks |
+| `CF_COMPOSE_DIR` | From `compose_dir` in your config |
+| `CF_UID/GID/HOME/USER` | From current user (for NFS compatibility) |
+| `CF_LOCAL_HOST` | By matching local IPs to configured hosts |
+
+If auto-detection fails for any value, edit the `.env` file manually.
+
+### Glances Monitoring
+
+To show host CPU/memory stats in the dashboard, deploy [Glances](https://nicolargo.github.io/glances/) on your hosts. If `CF_LOCAL_HOST` wasn't detected correctly, set it to your local hostname:
+
+```bash
+CF_LOCAL_HOST=nas  # Replace with your local host name
+```
+
+See [Host Resource Monitoring](https://github.com/basnijholt/compose-farm#host-resource-monitoring-glances) in the README.
+
+---
+
+## Troubleshooting
+
+### SSH "Permission denied" or "Host key verification failed"
+
+Regenerate keys:
+
+```bash
+docker compose run --rm cf ssh setup
+```
+
+### Glances shows error for local host
+
+Add your local hostname to `.env`:
+
+```bash
+echo "CF_LOCAL_HOST=nas" >> .env
+docker compose restart web
+```
+
+### Files created as root
+
+Add the non-root variables above and restart.
+
+---
+
+## All Environment Variables
+
+For advanced users, here's the complete reference:
+
+| Variable | Description | Default |
+|----------|-------------|---------|
+| `DOMAIN` | Domain for Traefik labels | *(required)* |
+| `CF_COMPOSE_DIR` | Compose files directory | `/opt/stacks` |
+| `CF_UID` / `CF_GID` | User/group ID | `0` (root) |
+| `CF_HOME` | Home directory | `/root` |
+| `CF_USER` | Username for SSH | `root` |
+| `CF_LOCAL_HOST` | Local hostname for Glances | *(auto-detect)* |
+| `CF_SSH_DIR` | SSH keys directory | `~/.ssh/compose-farm` |
+| `CF_XDG_CONFIG` | Config/backup directory | `~/.config/compose-farm` |

+**Running as non-root user** (recommended for NFS mounts):
+
+By default, containers run as root. To preserve file ownership on mounted volumes, set these environment variables in your `.env` file:
+
+```bash
+# Add to .env file (one-time setup)
+echo "CF_UID=$(id -u)" >> .env
+echo "CF_GID=$(id -g)" >> .env
+echo "CF_HOME=$HOME" >> .env
+echo "CF_USER=$USER" >> .env
+```
+
+Or use [direnv](https://direnv.net/) to auto-set these variables when entering the directory:
+```bash
+cp .envrc.example .envrc && direnv allow
+```
+
+This ensures files like `compose-farm-state.yaml` and web UI edits are owned by your user instead of root. The `CF_USER` variable is required for SSH to work when running as a non-root user.
