requires:
|
|
- phase: 02-docker-integration
|
|
provides: Docker socket access, container list API, fuzzy matching logic
|
|
provides:
|
|
- Container start/stop/restart via Telegram commands
|
|
- Action command routing in n8n workflow
|
|
- Single-match immediate execution flow
|
|
- Multiple-match placeholder for confirmation (Plan 03-02)

key-decisions:

patterns-established:
|

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

# 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
|
|
- **Files modified:** 1
|
|
|
|
## 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:
|
|
|
|
1. **Task 1: Add action command routing to workflow** - `4848e7d` (feat)
|
|
2. **Task 2: Implement container matching and action execution** - `f466a29` (feat)
|
|
3. **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
