n8n-workflow.json

Treat HTTP 304 (already in state) as success

Use 10-second graceful timeout for stop/restart

Route by match count: 0, 1, >1, error

Action command pattern: start/stop/restart <name>

Build curl command in Code node, execute in Execute Command node

Parse HTTP status in separate Code node for error handling

Phase 03 Plan 01: Basic Container Actions Summary

Single-match container actions (start/stop/restart) execute immediately via Docker API POST calls with graceful timeout

Performance

Duration: 12 min
Started: 2026-01-30T10:00:00Z
Completed: 2026-01-30T10:12:00Z
Tasks: 3

Accomplishments

Action command routing for start/stop/restart patterns
Fuzzy container matching with case-insensitive substring search
Docker API POST calls for container lifecycle actions
HTTP status code handling (204 success, 304 already-in-state, error codes)
Error handling for Docker connection failures and action errors

Task Commits

Each task was committed atomically:

Task 1: Add action command routing to workflow - 4848e7d (feat)
Task 2: Implement container matching and action execution - f466a29 (feat)
Task 3: Handle action errors gracefully - 2bd90c8 (feat)

Files Created/Modified

n8n-workflow.json - Extended with action branch: Parse Action, Docker List for Action, Match Container, Check Match Count, Build Action Command, Execute Action, Parse Action Result, Send Action Result, error handlers

Decisions Made

Treat HTTP 304 (container already in desired state) as success - user doesn't need to know it was already stopped/started
Use 10-second timeout (?t=10) for stop/restart to allow graceful shutdown
Route by matchCount with explicit error check (matchCount < 0) for Docker connection failures
Multiple match placeholder returns message indicating confirmation will come in next update

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None

User Setup Required

None - no external service configuration required.

Next Phase Readiness

Single-match actions fully functional
Ready for Plan 03-02: Confirmation flow for multiple matches
Inline keyboard buttons will use HTTP Request node (not native Telegram node) per RESEARCH.md
