# Milestone v1.1: n8n Integration & Polish

**Status:** ✅ SHIPPED 2026-02-04
**Phases:** 6-9
**Total Plans:** 11

## Overview

Enable faster development iteration via n8n API access, improve UX with inline keyboard buttons, add batch operations, and harden security by removing direct Docker socket exposure from n8n.

## Phases

### Phase 6: n8n API Access

**Goal**: Claude Code can programmatically read, update, and test workflows

**Depends on**: None (enables faster iteration on all subsequent phases)

**Requirements:** API-01, API-02, API-03, API-04

**Plans:** 1 plan

Plans:
- [x] 06-01-PLAN.md — Enable API access (create key, verify CRUD, execution history)

**Success Criteria:**
1. ✅ n8n API key exists and Claude Code can authenticate against the n8n API
2. ✅ Claude Code can retrieve the current workflow JSON via API call
3. ✅ Claude Code can push workflow changes via API and they take effect immediately
4. ✅ Claude Code can view execution history showing recent runs with success/failure status

**Details:**
- n8n API authentication via X-N8N-API-KEY header
- Workflow ID: HmiXBlJefBRPMS0m4iNYc
- Credentials stored in .env.n8n-api (gitignored)
- Full CRUD operations verified

---

### Phase 7: Socket Security

**Goal**: Docker operations flow through a filtered proxy instead of direct socket access

**Depends on**: Phase 6 (API access enables faster iteration on curl command migration)

**Requirements:** SEC-01, SEC-02, SEC-03, SEC-04

**Plans:** 3 plans

Plans:
- [x] 07-01-PLAN.md — Deploy docker-socket-proxy via Unraid CA
- [x] 07-02-PLAN.md — Migrate workflow curl commands to proxy
- [x] 07-03-PLAN.md — Verify dangerous APIs are blocked

**Success Criteria:**
1. ✅ Socket proxy container runs on internal network with Docker socket mounted
2. ✅ n8n container connects to proxy via TCP instead of mounting docker.sock directly
3. ✅ Dangerous Docker APIs (exec, create, build) return blocked/forbidden responses
4. ✅ All existing bot commands (status, start, stop, restart, update, logs) work identically through proxy

**Details:**
- tecnativa/docker-socket-proxy deployed on dockernet network
- 16 curl commands migrated from unix socket to TCP proxy
- Exec, build, commit APIs blocked (403 Forbidden)
- Container create allowed for update command functionality
- docker.sock mount removed from n8n container

### Phase 8: Inline Keyboard Infrastructure

**Goal**: Users interact with containers via tappable buttons instead of typing commands

**Depends on**: Phase 7 (security in place before adding new features)

**Requirements:** KEY-01, KEY-02, KEY-03, KEY-04, KEY-05

**Plans:** 3 plans

Plans:
- [x] 08-01-PLAN.md — Container list keyboard and submenu navigation
- [x] 08-02-PLAN.md — Action execution and confirmation flow
- [x] 08-03-PLAN.md — Progress feedback and completion messages

**Success Criteria:**
1. ✅ Status command returns a message with inline buttons showing available actions per container
2. ✅ Tapping an action button (start/stop/restart) executes that action on the target container
3. ✅ Dangerous actions (stop, update) show a confirmation prompt before executing
4. ✅ During operation execution, the message updates to show progress (e.g., "Updating...")
5. ✅ After action completes, buttons are removed and final status is shown in the message

**Details:**
- Callback data format: colon-separated for 64-byte compliance
- 6 containers per page with pagination
- Running containers first with green circle icon
- All transitions use editMessageText (no message clutter)
- 30-second confirmation timeout with cancel option
- 37 new nodes added for action execution and confirmation

### Phase 9: Batch Operations

**Goal**: Users can update multiple containers in a single command with clear feedback

**Depends on**: Phase 8 (keyboard infrastructure supports confirmation dialogs)

**Requirements:** BAT-01, BAT-02, BAT-03, BAT-04, BAT-05, BAT-06

**Plans:** 4 plans

Plans:
- [x] 09-01-PLAN.md — Batch command parsing and container matching
- [x] 09-02-PLAN.md — Sequential batch execution with progress feedback
- [x] 09-03-PLAN.md — "Update all" and inline multi-select
- [x] 09-04-PLAN.md — Verification and testing

**Success Criteria:**
1. ✅ User can type "stop container1 container2" and all containers stop sequentially
2. ✅ Each container shows individual progress/result as it completes (not waiting until all finish)
3. ⏸️ "Update all" command shows confirmation with list of containers before executing (testing deferred)
4. ✅ If one container fails mid-batch, remaining containers still attempt to execute
5. ✅ Final message shows summary: "3 updated, 1 failed" with details

**Details:**
- Exact-match priority in container matching
- Two-phase execution for name-only callbacks
- onError: continueRegularOutput for non-aborting batch
- 64-byte callback_data limit enforced (~8 containers max in multi-select)
- Checkmark toggle UI for visual selection feedback

---

## Milestone Summary

**Key Decisions:**
- n8n API key with never-expire policy for development
- docker-socket-proxy for filtered Docker API access
- Colon-separated callback format for 64-byte compliance
- Exact match priority in container matching
- Stop/update require confirmation; start/restart/logs immediate

**Issues Resolved:**
- Telegram webhook only works via manual execute (deferred to WEB-01)
- Array handling in n8n Code nodes ($input.all() pattern)
- Message edit conflicts with identical content (timestamp solution)

**Issues Deferred:**
- Batch update via inline keyboard (complex sequence, needs modularization)
- Webhook fix (WEB-01 in Phase 10)
- Environment variable audit (Phase 10)
- Unraid update badge sync (Phase 10)

**Technical Debt Incurred:**
- Update flow duplicated between single and batch paths
- Workflow now 8,485 lines (complexity growing)
- Long container names hit 64-byte callback limit
