Docker Build Fix Verification & Deployment Plan

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: Verify that TypeScript build errors are fixed locally, test Docker build pipeline, and ensure remote deployment succeeds.

Architecture: Verify committed TypeScript fixes, rebuild Docker frontend image, run integration tests, confirm remote server deployment, and update handover state.

Tech Stack: Docker Compose, Next.js 15, TypeScript, Node 20-alpine

---

CONTEXT

Problem: Remote Docker deployment failed with:

Type error: Type 'string | null' is not assignable to type 'string | Blob | undefined'.
  Type 'null' is not assignable to type 'string | Blob | undefined'.
  350 |        <div className="flex-1 flex flex-col gap-6 min-h-0 overflow-hidden">
  351 |          <div className="relative flex-1 min-h-0 rounded-[2.5rem] overflow-hidden border-4 border-slate-900 shadow-2xl bg-slate-900">
  > 352 |            <img src={image} className="w-full h-full object-contain" alt="Captured label" />

Solution Applied: Commit 65b24079 fixed both AIOnboarding.tsx:352 and Scanner.tsx:237 using || undefined pattern.

Current Branch: dev (fixes committed, staged for merge to master)

---

Task 1: Verify Local Docker Build

Files:

• Test: frontend/Dockerfile

• Test: docker-compose.yml

• Verify: frontend/components/AIOnboarding.tsx:352

• Verify: frontend/components/Scanner.tsx:237

• Step 1: Confirm Docker is installed and running

docker --version
docker-compose --version

Expected: Both return version numbers (e.g., "Docker version 27.x.x", "Docker Compose version 2.x.x")

If Docker Desktop is not running on macOS, start it:

open /Applications/Docker.app
sleep 10  # Wait for Docker daemon to start
docker ps  # Verify daemon is responding

• Step 2: Verify the committed fixes are in place

git log --oneline -3

Expected output includes commit: 65b24079 fix: resolve TypeScript build error in AIOnboarding and Scanner components

Verify the actual code changes:

git show 65b24079:frontend/components/AIOnboarding.tsx | grep -A 2 "src={image"
git show 65b24079:frontend/components/Scanner.tsx | grep -A 2 "src={capturedImage"

Expected: Both lines should show || undefined pattern:

<img src={image || undefined} ...
<img src={capturedImage || undefined} ...

• Step 3: Build the frontend Docker image locally

cd /Users/danielbedeleanu/_nu_Backup/_BEDE_/_programare_2026_/cu.AI/inventory
docker-compose build frontend --no-cache 2>&1 | tee /tmp/docker-build.log

Expected: Build completes successfully with message:

[frontend] exporting to image
=> => naming to docker.io/library/ainventory-frontend

If build fails, search the log for the error:

grep -i "error\|failed" /tmp/docker-build.log

• Step 4: Verify the built image exists and contains the fixes

docker images | grep ainventory-frontend
docker inspect ainventory-frontend:latest | grep -i "created\|os\|arch"

Expected: Image exists with recent creation timestamp.

---

Task 2: Full Docker Compose Stack Build

Files:

• Test: docker-compose.yml

• Test: Dockerfile (proxy, backend, frontend)

• Verify: All three services build without errors

• Step 1: Clean up any previous build artifacts

docker-compose down -v
docker system prune -f --volumes

Expected: All containers and volumes removed cleanly.

• Step 2: Run full Docker Compose build

docker-compose build --no-cache 2>&1 | tee /tmp/docker-full-build.log

Expected: All three services build successfully:

• [proxy] exporting to image ✓
• [backend] exporting to image ✓
• [frontend] exporting to image ✓

If any service fails, extract the error:

grep -A 20 "ERROR\|Failed" /tmp/docker-full-build.log

• Step 3: Verify all images built successfully

docker images | grep ainventory

Expected output shows three images:

ainventory-frontend       latest
ainventory-backend        latest
ainventory-proxy          latest

• Step 4: Commit the build success (mark in code)

No code changes needed. Just document the verification in the handover.

git status

Expected: No uncommitted changes (all fixes already committed in Task 1).

---

Task 3: Run Integration Test (Compose Up)

Files:

• Test: docker-compose.yml (all services)

• Test: backend/entrypoint.sh

• Test: frontend/public/manifest.json

• Verify: data/inventory.db initialization

• Step 1: Start the full stack

cd /Users/danielbedeleanu/_nu_Backup/_BEDE_/_programare_2026_/cu.AI/inventory
docker-compose up -d 2>&1 | tee /tmp/docker-up.log

Expected: All containers start successfully:

[+] Running 3/3
 ✔ Container ainventory-proxy-1     Started
 ✔ Container ainventory-backend-1   Started
 ✔ Container ainventory-frontend-1  Started

• Step 2: Wait for services to stabilize

sleep 5
docker-compose ps

Expected: All three containers show "Up" status:

NAME                     STATUS
ainventory-proxy-1       Up (healthy)
ainventory-backend-1     Up (healthy)
ainventory-frontend-1    Up (healthy)

• Step 3: Check backend health endpoint

curl -s http://localhost:8906/health || echo "Backend not responding yet"
curl -s -k https://localhost:8909/api/health | head -20

Expected: Backend returns JSON response (may be 401 if auth is required, but should not be a connection error).

• Step 4: Check frontend is serving

curl -s http://localhost:8907 | head -50

Expected: Returns HTML containing <title>aInventory - TFM</title> or similar Next.js metadata.

• Step 5: Review logs for any TypeScript errors

docker-compose logs frontend | grep -i "error\|type.*is not assignable\|failed to compile"

Expected: NO TypeScript compilation errors. (This was the bug we fixed.)

• Step 6: Stop the stack

docker-compose down

Expected: All containers stopped and removed cleanly.

---

Task 4: Document & Handover

Files:

• Update: dev_docs/SESSION_STATE.md

• Update: README.md (if deployment instructions changed)

• Step 1: Write handover notes to SESSION_STATE.md

Update the file with:

# CURRENT AI WORKING SESSION — HANDOVER

**Active AI:** [Next AI name]
**Last Updated:** 2026-04-15
**Current Version:** v1.9.21 (Docker-Verified)
**Branch:** dev (ready for master merge)

---

## STATUS: 🟢 STABLE — DOCKER BUILD VERIFIED LOCALLY

**TypeScript Build Error FIXED:**
- **Commit:** 65b24079 - Fix TypeScript build error in AIOnboarding and Scanner
- **Issue:** `Type 'string | null' is not assignable to type 'string | Blob | undefined'`
- **Root Cause:** React 19 / Next.js 15 no longer accepts `null` for `<img src>` attribute
- **Solution:** Used `image || undefined` pattern in AIOnboarding.tsx:352 and Scanner.tsx:237
- **Status:** ✓ Committed, ✓ Local Docker build verified, ✓ Ready for remote deployment

**What Was Verified:**
1. ✓ Docker frontend image builds without TypeScript errors
2. ✓ Full docker-compose stack (proxy, backend, frontend) builds successfully
3. ✓ Services start and respond to health checks
4. ✓ Frontend serves and contains no TypeScript compilation errors in logs

**Next Steps for Remote Deployment:**
1. Push `dev` branch to remote repository (if not already pushed)
2. Run remote deployment: `./deploy.sh --reset-ssl` on the server
3. Verify all three containers start successfully
4. Check logs for any runtime errors (not TypeScript - those are now fixed)
5. Test the UI in browser to confirm the image capture works

---

✓ Done.

• Step 2: Add a note about next deployment

If any issues were found during local testing, document them in this task. If everything passed, note that remote deployment can proceed.

• Step 3: Commit the handover notes

git add dev_docs/SESSION_STATE.md
git commit -m "docs: update session state - Docker build verified locally, ready for remote deployment"

Expected: Commit succeeds.

• Step 4: Push to remote (optional, if CI/CD requires)

If the repository uses CI/CD automation:

git push origin dev

If manual deployment:

echo "Ready for manual push to remote server"

---

Self-Review Checklist

✓ Spec coverage: All requirements met

• TypeScript build fix verified in code
• Docker build tested locally
• All three services verified
• Integration test confirms services start
• Handover documentation complete

✓ No placeholders: All steps have actual commands and expected output

✓ Type consistency: TypeScript || undefined pattern is consistent across both files

✓ Clarity: Each step is self-contained and executable

---

If Remote Deployment Still Fails

Diagnostic Steps:

1. Verify the remote server has the latest code:

   ssh root@docker "cd /data/docker/aInventory && git log --oneline -5"
   

   Should show commit 65b24079 in the history.

2. If not, pull the latest changes:

   ssh root@docker "cd /data/docker/aInventory && git pull origin dev"
   

3. Re-run the deployment:

   ssh root@docker "cd /data/docker/aInventory && ./deploy.sh --reset-ssl"
   

4. If still failing, capture full Docker build output:

   ssh root@docker "docker-compose build frontend --no-cache 2>&1 | head -200"
