# Plan 05-03 Summary: Deployment README & Testing

## What Was Built

### Task 1: Deployment README
- Complete deployment guide at `README.md`
- Step-by-step installation instructions for Unraid
- Documents n8n container configuration (Docker socket, curl binary)
- Documents credential creation (Telegram API, user ID auth)
- Usage section with all 6 commands

### Task 2: End-to-End Testing
All commands verified working via Telegram:
- **Menu**: /start and unknown text show command list
- **Status**: Lists containers with status indicators
- **Start/Stop/Restart**: Control containers with confirmation messages
- **Update**: Pulls image, recreates container, notifies if already up-to-date
- **Logs**: Configurable line count, HTML-escaped output

## Bug Fixes During Testing

| Issue | Fix | Commit |
|-------|-----|--------|
| Show Menu 404 | Switched to native Telegram node | 0b6dfe6 |
| HTML parse error in menu | Changed `<name>` to `[name]` | 0b6dfe6 |
| Container matching (jellyplex vs plex) | Prioritize exact matches | 004911e |
| Update missing acknowledgment | Send "Updating..." immediately | d03e79c |
| Pull rate limiting | Added error detection for toomanyrequests | d03e79c |
| Old image not removed | Added image cleanup after update | 0839c44 |
| Old image removal failed | Fixed data reference through Telegram node | 88830a8 |
| Pull hanging/memory exhaustion | Pipe output through `tail -c 10000` | 3e3b9ae |
| Pull downloading all tags | Append `:latest` when tag missing | 74dd8f1 |
| Logs HTML parse error | Escape `<`, `>`, `&` in log content | 287c722 |
| Logs line count ignored | Fix property name `lineCount` → `lines` | 808d1af |
| No message when up-to-date | Add "already up to date" notification | c979a7f |

## Decisions Made

| Decision | Rationale |
|----------|-----------|
| Text menu over keyboard | Native Telegram node's replyKeyboard had issues |
| Hardcoded user ID | n8n IF nodes don't support $credentials references |
| Exact match priority | Prevents substring collisions (plex/jellyplex) |
| 10-minute pull timeout | Balance between large images and feedback |
| Tail last 10KB of pull output | Capture errors without memory exhaustion |
| Default to :latest tag | Prevents Docker from pulling all tags |
| HTML escape log content | Logs may contain `<tag>` text |

## Files Modified
