# Docker Environment Status Report
**Generated:** October 21, 2025 @ 09:45 AM  
**Environment:** Development (Docker)

---

## 🟢 Overall Status: OPERATIONAL

All critical services are running and accepting connections. Minor health check issue on frontend (cosmetic - does not affect functionality).

---

## 📊 Container Status

### 1. **Backend (myclub-backend)** ✅ HEALTHY
- **Container ID:** `2f6ca942fc79`
- **Image:** `fotbal-club-backend`
- **Status:** Up 16 minutes
- **Health:** ✅ **HEALTHY**
- **Port:** `8080:8080` (Host:Container)
- **CPU Usage:** 0.00%
- **Memory:** 49.86 MiB / 2 GiB
- **Network I/O:** 1.51MB sent / 1.11MB received
- **Health Check:** `wget http://localhost:8080/api/v1/health` → ✅ PASSING

**Backend API Response:**
```json
{
    "status": "ok"
}
```

**Recent Activity (Last 50 lines):**
- ✅ API endpoints responding normally (200 OK)
- ✅ Database queries executing successfully
- ✅ Cache system operational
- ✅ CORS configured properly

```

### 2. **Frontend (myclub-frontend)** ⚠️ UNHEALTHY (but functional)
- **Container ID:** `26adece8cbc1`
- **Image:** `fotbal-club-frontend`
- **Status:** Up 16 minutes
- **Health:** ⚠️ **UNHEALTHY** (false positive)
- **Port:** `3000:80` (Host:Container)
- **CPU Usage:** 0.00%
- **Memory:** 15.95 MiB / 1 GiB
- **Network I/O:** 435kB sent / 21.2MB received
- **HTTP Status:** ✅ 200 OK (verified with curl)

**Health Check Issue:**
The container health check is failing because:
```
Health Check: wget http://localhost:80/
Error: "wget: can't connect to remote host: Connection refused"
```

**Root Cause:** The health check is trying `localhost:80` from inside the container, but Nginx might be binding differently. However, **the frontend IS working perfectly** when accessed from the host machine at `http://localhost:3000`.

**Recent Activity:**
- ✅ Serving React application successfully
- ✅ All static assets loading (main.js, main.css)
- ⚠️ Some missing image files (expected - need to be uploaded):
  - `/images/club-logo.png` → 404
  - `/images/club-opponent.png` → 404
  - `/images/news/placeholder.jpg` → 404
  - `/dist/img/logo-club-empty.svg` → 404

**User Access Logs:**
```
GET /admin/hraci → 200
GET /admin/clanky → 200
GET /admin/o-klubu → 200
GET / → 200 (homepage working)
```

---

### 3. **Database (myclub-db)** ✅ HEALTHY
- **Container ID:** `7f5ef9341913`
- **Image:** `postgres:15-alpine`
- **Status:** Up 16 minutes
- **Health:** ✅ **HEALTHY**
- **Port:** `5432:5432` (Host:Container)
- **CPU Usage:** 0.00%
- **Memory:** 100.8 MiB / 2 GiB
- **Network I/O:** 732kB sent / 1.13MB received
- **Health Check:** `pg_isready -U postgres` → ✅ PASSING

**Database Configuration:**
```
User: postgres
Database: fotbal_club
Encoding: UTF-8
Max Connections: 200
Shared Buffers: 256MB
```

**Recent Activity:**
- ✅ Accepting connections
- ✅ Query execution normal
- ✅ GORM queries optimized and using prepared statements
- ✅ No connection pool exhaustion

**Sample Queries:**
```sql
SELECT * FROM "sponsors" WHERE "deleted_at" IS NULL → 0.079ms
SELECT * FROM "articles" WHERE featured = 't' → 0.062ms
SELECT * FROM "players" → executing normally
```

## 🌐 Port Mappings & Accessibility

| Service | Internal Port | External Port | Accessible From Host | Status |
|---------|--------------|---------------|---------------------|--------|
| Frontend | 80 | 3000 | http://localhost:3000 | ✅ Working |
| Backend API | 8080 | 8080 | http://localhost:8080 | ✅ Working |
| Database | 5432 | 5432 | localhost:5432 | ✅ Working |

**Verification:**
```bash
✅ curl http://localhost:3000/ → HTTP 200
✅ curl http://localhost:8080/api/v1/health → {"status": "ok"}
✅ Backend accessible from frontend (API calls working)
```

## 🔧 Important Notes

### 1. **Rich Text Editor CSS Fix Status**
⚠️ **The CSS fix I applied is NOT yet active in the running container**

The changes made to fix the rich text editor visibility are in the source code:
- ✅ `frontend/src/index.tsx` - CSS imports added
- ✅ `frontend/src/components/common/CustomRichEditor.tsx` - Cleaned up

**However:** The Docker container is running a **pre-built** version of the frontend from before the fix.

**To apply the fix, you need to rebuild:**
```bash
# Option 1: Rebuild just the frontend
docker-compose build frontend
docker-compose up -d frontend

# Option 2: Rebuild everything
docker-compose down
docker-compose build
docker-compose up -d
```

### 2. **Frontend Health Check False Positive**
The frontend shows as "unhealthy" but is actually working perfectly. This is a Docker health check configuration issue, not a functional problem.

**To fix permanently (optional):**
Edit `docker-compose.yml` line 76:
```yaml
# CURRENT (failing):
healthcheck:
  test: ["CMD", "wget", "--spider", "-q", "http://localhost:80/"]

# BETTER:
healthcheck:
  test: ["CMD", "wget", "--spider", "-q", "http://127.0.0.1:80/"]
  # or
  test: ["CMD", "curl", "-f", "http://127.0.0.1:80/"]
```

### 3. **Missing Static Files**
These are expected missing files that should be uploaded via the admin panel:
- Club logo
- Club opponent logo
- News placeholder images

These don't affect functionality - just placeholder images won't show.

---

## 📝 Action Items

### Immediate (To Apply Rich Editor Fix):
1. ⚠️ **Rebuild frontend container** to get the CSS fix:
   ```bash
   docker-compose build frontend
   docker-compose restart frontend
   ```

2. 🔄 **Clear browser cache** after restart:
   - Hard refresh: `Ctrl+Shift+R` (Linux/Windows) or `Cmd+Shift+R` (Mac)

### Optional Improvements:
3. 🔧 Fix frontend health check in `docker-compose.yml`
4. 📸 Upload club logos via admin panel to eliminate 404s
5. 🗄️ Verify database migrations are complete

## 🎯 Performance Summary

| Metric | Status | Details |
|--------|--------|---------|
| Backend Response Time | ✅ Excellent | 0.5-12ms average |
| Memory Usage | ✅ Normal | All containers < 50% of limits |
| CPU Usage | ✅ Idle | 0% (no active load) |
| Network I/O | ✅ Healthy | Minimal overhead |
| Database Queries | ✅ Optimized | Using prepared statements |

---

## 🚀 Quick Reference Commands

```bash
# View logs
docker logs myclub-backend --tail 50
docker logs myclub-frontend --tail 50
docker logs myclub-db --tail 50

# Check health
docker ps
docker inspect myclub-backend --format='{{.State.Health.Status}}'

# Restart services
docker-compose restart backend
docker-compose restart frontend

# Rebuild and restart
docker-compose build frontend
docker-compose up -d

# Access database
docker exec -it myclub-db psql -U postgres -d fotbal_club
```

---

## ✅ Conclusion

**System is fully operational** with one cosmetic health check warning that doesn't affect functionality. 

**Next Step:** Rebuild the frontend container to apply the rich text editor CSS fix, then verify the editor is visible in the admin panel.
