Phase 9 Plan 02: Batch Execution and Progress Summary

Sequential batch execution with Loop Over Items, per-container progress edits, error isolation, and failure-emphasized summaries

Performance

• Duration: 7 min
• Started: 2026-02-04T02:26:37Z
• Completed: 2026-02-04T02:33:47Z
• Tasks: 3
• Files modified: 1

Accomplishments

• Sequential batch execution loop processes containers one at a time
• Progress message updates in real-time for each container being processed
• One container failure does not abort the batch - remaining containers continue
• Final summary emphasizes failures with container names and reasons
• Back to List button for navigation after batch completion

Task Commits

Each task was committed atomically:

1. Task 1: Add Loop Over Items for sequential batch execution - 62f50cb (feat)
2. Task 2: Add per-container progress updates and action execution - fd4c614 (feat)
3. Task 3: Add batch summary with failure emphasis - b704a6c (feat)

Files Created/Modified

• n8n-workflow.json - Added 20 new nodes for batch execution flow

New Nodes Added (20 total)

Batch Initialization (4)

1. Initialize Batch State - Prepares batch data structure
2. Send Batch Start Message - Initial "Starting batch..." message
3. Prepare Batch Loop - Formats containers for loop iteration
4. Batch Loop - splitInBatches node with batch size 1

Progress and Execution (10)

5. Build Progress Message - Creates per-container progress text
6. Edit Progress Message - Updates Telegram message
7. Route Batch Loop Action - Routes by action type
8. Build Batch Action Command - Prepares curl command
9. Execute Batch Container Action - Runs the action
10. Check Batch Action Result - Handles lookup vs direct result
11. Needs Action Call - IF node for two-phase execution
12. Execute Batch Action 2 - Second phase execution
13. Parse Batch Action 2 - Parses second phase result
14. Handle Action Result - Aggregates success/failure/warning

Loop Control and Summary (4)

15. Prepare Next Iteration - Sets isComplete flag
16. Is Batch Complete - Routes to summary or loop continuation
17. Build Batch Summary - Creates failure-emphasized summary
18. Send Batch Summary - Posts final summary with Back to List button

Callback Preparation (2)

19. Prepare Batch Stop Exec - Transforms bstop:confirm callback data
20. Prepare Batch Exec - Transforms bexec callback data

Decisions Made

Decision	Rationale
Two-phase execution for name-only containers	Callbacks from bstop/bexec have names but no IDs - need lookup first
onError: continueRegularOutput	Ensures one failure doesn't abort entire batch
Is Batch Complete IF node	Clean routing to summary instead of relying on loop second output
Warnings shown in detail for <= 3	Per context discretion - show details when few, summary when many
Progress edit every container	Typical batch is 2-5 containers, rate limiting not a concern

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None

User Setup Required

None - no external service configuration required.

Next Phase Readiness

Ready for Plan 03: Batch update workflow integration.

The following are now available for Plan 03:

• Complete batch execution pipeline for start/stop/restart
• Route Batch Loop Action output 0 (update) is empty - needs full update flow
• Pattern established for sequential execution with progress
• Error isolation and summary patterns ready to reuse

Note: Route Batch Loop Action update output needs to connect to the full update sequence (pull, stop, remove, create, start) similar to single-container update flow.
