`6caa0f1` (feat) + +## Files Created/Modified + +- `n8n-update.json` - Restructured from 34 to 29 nodes, replaced Docker API calls with GraphQL updateContainer mutation + +## Decisions Made + +1. **60-second HTTP timeout for updateContainer**: Docker's image pull timeout was 600s (10 minutes), but that included the external `curl` command overhead. The GraphQL mutation handles the pull internally, so 60 seconds is sufficient for most images (10GB+ images take 20-30s on gigabit). This is 4x the standard 15s timeout for quick operations. + +2. **ImageId field comparison for update detection**: Docker workflow compared image digests from separate inspect calls. Unraid's `updateContainer` mutation returns the updated container's `imageId` field. Comparing before/after `imageId` values determines if an update actually occurred (different = updated, same = already up to date). + +3. **Dual query paths converge to single state capture**: "Has Container ID?" IF node splits into two paths: + - True (direct ID): Query Single Container → Normalize → Capture State + - False (name lookup): Query All Containers → Normalize → Registry Update → Resolve ID → Capture State + Both paths merge at "Capture Pre-Update State" node for consistent data structure downstream. + +4. **Error routing via IF node**: Code nodes in n8n have a single output. "Handle Update Response" outputs both success and error cases in one output (with `error: true` flag). Added "Check Update Success" IF node to route based on error flag: success → Check If Updated, error → Format Update Error. + +5. **Remove Old Image node eliminated**: Docker required manual cleanup of old images after container recreation. Unraid's `updateContainer` mutation handles image cleanup automatically, so the "Remove Old Image (Success)" HTTP Request node was removed entirely. + +6. **Preserve all messaging nodes unchanged**: The 15 messaging nodes (3 sets of 5: Format Result → Check Response Mode → Send Inline/Text → Return) were kept exactly as-is, except for updating node references in the Format nodes to point to "Handle Update Response" instead of deleted Docker flow nodes. + +## Deviations from Plan + +None - plan executed exactly as written.
