# Phase 10 Plan 3: Container Actions Sub-workflow Summary
|
||||
|
||||
**Extracted container start/stop/restart actions into dedicated sub-workflow (209 nodes, +9 integration nodes)**
|
||||
|
||||
## Performance
|
||||
|
||||
- **Duration:** 6 min
|
||||
- **Started:** 2026-02-04T18:05:50Z
|
||||
- **Completed:** 2026-02-04T18:11:40Z
|
||||
- **Tasks:** 3 (create sub-workflow, wire main workflow, deploy)
|
||||
- **Files created:** 1 (n8n-container-actions.json)
|
||||
- **Files modified:** 1 (n8n-workflow.json)
|
||||
|
||||
## Accomplishments
|
||||
|
||||
- Created container-actions sub-workflow with 8 nodes
|
||||
- Input contract: containerId, containerName, action, chatId, messageId, responseMode
|
||||
- Output contract: success, message, action, containerName, containerId, chatId, messageId, responseMode
|
||||
- Added 9 nodes to main workflow for sub-workflow integration
|
||||
- Wired 3 action paths through sub-workflow:
|
||||
- Text command path (single match)
|
||||
- Inline keyboard path (start/restart)
|
||||
- Confirmed stop path
|
||||
- Used environment variable pattern for workflow ID reference
|
||||
|
||||
## Task Commits
|
||||
|
||||
Each task was committed atomically:
|
||||
|
||||
1. **Task 1: Create container-actions sub-workflow** - `35705a7` (feat)
|
||||
2. **Task 2: Wire main workflow to use sub-workflow** - `d07932f` (feat)
|
||||
|
||||
**Task 3: Deploy and verify** - Requires n8n access (see User Setup Required)
|
||||
|
||||
## Files Created/Modified
|
||||
|
||||
- `n8n-container-actions.json` - New sub-workflow (8 nodes, 303 lines)
|
||||
- `n8n-workflow.json` - Added 9 integration nodes (+234 lines)
|
||||
|
||||
## Decisions Made
|
||||
|
||||
**1. Environment variable for workflow ID:**
|
||||
- Using `$env.CONTAINER_ACTIONS_WORKFLOW_ID` for sub-workflow reference
|
||||
- Matches pattern established in 10-02 with CONTAINER_UPDATE_WORKFLOW_ID
|
||||
- Allows easy ID update without editing workflow JSON
|
||||
|
||||
**2. httpRequest nodes in sub-workflow:**
|
||||
- Sub-workflow uses n8n-nodes-base.httpRequest instead of curl commands
|
||||
- Cleaner JSON response handling with statusCode
|
||||
- onError: continueRegularOutput for graceful error handling
|
||||
|
||||
**3. Confirmation dialogs in main workflow:**
|
||||
- Stop confirmation dialog remains in main workflow (not extracted)
|
||||
- Batch stop confirmation remains in main workflow
|
||||
- Only the action execution after confirmation moves to sub-workflow
|
||||
|
||||
## Deviations from Plan
|
||||
|
||||
None - plan executed as written.
|
||||
|
||||
## Issues Encountered
|
||||
|
||||
**n8n API not accessible from execution environment:**
|
||||
- WSL cannot resolve n8n.berger.work
|
||||
- Task 3 (deploy and verify) requires manual user action
|
||||
- All local verification passed successfully
|
||||
|
||||
## User Setup Required
|
||||
|
||||
**To complete deployment:**
|
||||
|
||||
1. **Import container-actions sub-workflow:**
|
||||
- Open n8n web UI
|
||||
- Import `n8n-container-actions.json`
|
||||
- Note the assigned workflow ID
|
||||
|
||||
2. **Set environment variable:**
|
||||
- In n8n Settings > Variables, add:
|
||||
- `CONTAINER_ACTIONS_WORKFLOW_ID` = (workflow ID from step 1)
|
||||
|
||||
3. **Import/update main workflow:**
|
||||
- Import `n8n-workflow.json` (or update existing workflow)
|
||||
- Activate the workflow
|
||||
|
||||
4. **Verify functionality:**
|
||||
- Test text command: "start <container-name>"
|
||||
- Test text command: "stop <container-name>" (should work directly)
|
||||
- Test text command: "restart <container-name>"
|
||||
- Test inline keyboard: Start/Stop/Restart buttons
|
||||
- Test stop confirmation flow via inline keyboard
|
||||
|
||||
## Verification Results
|
||||
|
||||
| Check | Status |
|
||||

|
||||

|
||||

|
||||

|
||||
| Main workflow has executeWorkflow nodes | PASS |
|
||||
| 3 action paths use sub-workflow | PASS |
|
||||
| Confirmation dialogs in main workflow | PASS |
|
||||
| Text command actions work | Pending deployment |
|
||||
| Inline keyboard actions work | Pending deployment |
|
||||
| Stop confirmation works | Pending deployment |
|

## Architecture
|
||||
|
||||
```
|
||||
Main Workflow (n8n-workflow.json)
|
||||
|
|
||||
|-- Text Command Path:
|
||||
| Check Match Count -> Prepare Text Action Input
|
||||
| -> Execute Container Action (sub) -> Handle Text Action Result
|
||||
| -> Send Action Result
|
||||
|
|
||||
|-- Inline Keyboard Path (start/restart):
|
||||
| Route Action Type -> Prepare Immediate Action -> Get Container For Action
|
||||
| -> Prepare Inline Action Input -> Execute Inline Action (sub)
|
||||
| -> Handle Inline Action Result -> Send Immediate Result
|
||||
|
|
||||
|-- Inline Keyboard Path (stop):
|
||||
| Route Action Type -> Build Stop Confirmation -> Send Stop Confirmation
|
||||
| [User confirms]
|
||||
| Route Confirm Action -> Prepare Confirmed Stop -> Get Container For Stop
|
||||
| -> Prepare Confirmed Stop Input -> Execute Confirmed Stop Action (sub)
|
||||
| -> Handle Confirmed Stop Result -> Send Confirmed Stop Result
|
||||
|
||||
Container Actions Sub-workflow (n8n-container-actions.json)
|
||||
|
|
||||
When executed by another workflow
|
||||
-> Route Action (switch: start/stop/restart)
|
||||
-> Start Container (httpRequest)
|
||||
-> Stop Container (httpRequest)
|
||||
-> Restart Container (httpRequest)
|
||||
-> Format [Start|Stop|Restart] Result
|
||||
-> Return to caller
|
||||
```
|
||||
|
||||
## Next Phase Readiness
|
||||
|
||||
**Ready for Phase 10-04 (if applicable):**
|
||||
- Container actions consolidated in sub-workflow
|
||||
- Pattern established for additional sub-workflow extraction
|
||||
- Batch operations still use curl approach (not extracted to sub-workflow)
|
||||
|
||||
**Blockers for full verification:**
|
||||
- Requires n8n deployment access
|
||||
- User must set CONTAINER_ACTIONS_WORKFLOW_ID environment variable
