# Production Deployment Fix Summary

**Date**: 2025-10-27
**Status**: PARTIALLY FIXED - DB configuration corrected, but additional issues remain

---

## What Was Fixed

### 1. Database Configuration Corrected ✅

**Problem**: Wrong DB_PORT in production `.env.production`
- Line 15: `DB_PORT=3306` (MySQL port)
- Line 67: `DB_PORT=` (duplicate empty entry)
- Wrong username: `mdb-user` (should be `mdb_user`)
- Wrong password

**Solution Applied**:
```bash
# Copied correct .env.production from source of truth
ansible web_servers -m copy \
  -a "src=deployment/applications/environments/.env.production \
      dest=/home/deploy/michaelschiemer/shared/.env.production" \
  --vault-password-file deployment/infrastructure/.vault_pass
```

**Verification**:
```bash
DB_PORT=5432                              # ✅ Correct
DB_USERNAME=mdb_user                      # ✅ Correct
DB_PASSWORD=Qo2KNgGqeYksEhKr57pgugakxlothn8J  # ✅ Correct
```

### 2. Containers Restarted ✅

```bash
docker compose restart php web queue-worker
```

**Current Status**:
- **php**: Up 6 minutes (healthy) ✅
- **db**: Up 53 minutes (healthy) ✅
- **redis**: Up 53 minutes (healthy) ✅
- **web**: Up 6 minutes (UNHEALTHY) ⚠️
- **queue-worker**: Restarting (1) ❌

---

## Remaining Issues

### Issue 1: Web Container Unhealthy ⚠️

**Symptom**: Website still returns HTTP 500

**Possible Causes**:
1. **PHP-FPM not responding** - Web container can't connect to PHP
2. **Application error** - PHP code failing during bootstrap
3. **Missing files** - Application files not properly deployed
4. **Permissions** - Web server can't access application files

**Next Steps to Diagnose**:
```bash
# Check if PHP-FPM is accessible from web container
docker exec web curl http://php:9000

# Check Nginx configuration
docker exec web nginx -t

# Check web container health check
docker inspect web --format='{{json .State.Health}}' | jq

# Check if application files exist
docker exec web ls -la /var/www/html/public/index.php
```

### Issue 2: Queue Worker Crashing ❌

**Symptom**: Continuous restart loop

**Possible Causes**:
1. **Same DB connection issue** (should be fixed now)
2. **Missing queue configuration**
3. **Redis connection issue**
4. **Application code error in queue worker**

**Next Steps to Diagnose**:
```bash
# Check queue-worker logs
docker logs queue-worker --tail 100

# Try running queue worker manually
docker exec php php artisan queue:work --tries=1 --once
```

## Scripts Created ✅

### 1. Simple Deployment Script
**Location**: `/home/michael/dev/michaelschiemer/deployment/infrastructure/scripts/deploy.sh`
```bash
./deployment/infrastructure/scripts/deploy.sh
```

### 2. .env Update Script
**Location**: `/home/michael/dev/michaelschiemer/deployment/infrastructure/scripts/update-env.sh`
```bash
./deployment/infrastructure/scripts/update-env.sh
```

### 3. Quick Sync Script
**Location**: `/home/michael/dev/michaelschiemer/deployment/infrastructure/scripts/quick-sync.sh`
```bash
./deployment/infrastructure/scripts/quick-sync.sh
```

**Note**: All scripts updated to use `docker compose` (v2) instead of `docker-compose` (v1)

## Documentation Created ✅

### Comprehensive Deployment Analysis
**Location**: `/home/michael/dev/michaelschiemer/deployment/infrastructure/DEPLOYMENT_ANALYSIS.md`

**Contents**:
1. Complete deployment flow analysis
2. .env file sources and conflicts
3. Deployment command documentation
4. Step-by-step fix strategy
5. Cleanup recommendations
6. Post-fix verification checklist

## Recommended Next Actions

### Immediate (To Fix HTTP 500)

1. **Check Application Bootstrap**:
```bash
# Test if PHP application can start
ansible web_servers -m shell \
  -a "docker exec php php /var/www/html/public/index.php" \
  --vault-password-file deployment/infrastructure/.vault_pass
```

2. **Check Nginx-PHP Connection**:
```bash
# Test PHP-FPM socket
ansible web_servers -m shell \
  -a "docker exec web curl -v http://php:9000" \
  --vault-password-file deployment/infrastructure/.vault_pass
```

3. **Check Application Logs**:
```bash
# Look for PHP errors
ansible web_servers -m shell \
  -a "docker exec php ls -la /var/www/html/storage/logs/" \
  --vault-password-file deployment/infrastructure/.vault_pass
```

4. **Verify File Permissions**:
```bash
# Check if web server can read files
ansible web_servers -m shell \
  -a "docker exec web ls -la /var/www/html/public/" \
  --vault-password-file deployment/infrastructure/.vault_pass
```

### Short-Term (Within 24h)

1. **Fix Web Container Health** - Resolve HTTP 500 errors
2. **Fix Queue Worker** - Stop crash loop
3. **Full Deployment Test** - Run complete deployment playbook
4. **Verify All Services** - Ensure all containers healthy

### Long-Term (This Week)

1. **Update Playbook** - Add .env.production sync task
2. **Add Validation** - Pre-deployment .env validation script
3. **Document Process** - Update README with deployment guide
4. **Setup Monitoring** - Add health check alerts
5. **Cleanup Old Files** - Remove duplicate .env files

---

## Key Learnings

### 1. Deployment Flow Issues

**Problem**: Playbook doesn't sync `.env.production` to `shared/`
**Impact**: Manual updates required for configuration changes
**Solution**: Add sync task to playbook

### 2. Multiple .env Sources

**Problem**: 3 different `.env.production` files with conflicting content
**Resolution**: Use `deployment/applications/environments/.env.production` as source of truth

### 3. Docker Compose Version

**Problem**: Production uses Docker Compose v2 (`docker compose`)
**Impact**: Scripts using v1 syntax (`docker-compose`) fail
**Solution**: All scripts updated to v2 syntax

### 4. Symlink Chain Complexity

**Structure**:
```
current/.env → shared/.env.production
current/.env.production → shared/.env.production
```

**Risk**: If `shared/.env.production` is wrong, ALL releases break
**Mitigation**: Validate before deploy, backup before changes

## Quick Reference

### Check Production Status
```bash
cd /home/michael/dev/michaelschiemer/deployment/infrastructure

# Container status
ansible web_servers -i inventories/production/hosts.yml \
  -m shell -a "docker ps" --vault-password-file .vault_pass

# .env configuration
ansible web_servers -i inventories/production/hosts.yml \
  -m shell -a "cat /home/deploy/michaelschiemer/shared/.env.production" \
  --vault-password-file .vault_pass

# Application logs
ansible web_servers -i inventories/production/hosts.yml \
  -m shell -a "docker logs web --tail 50" --vault-password-file .vault_pass
```

### Deploy to Production
```bash
# Full deployment
./deployment/infrastructure/scripts/deploy.sh

# Update .env only
./deployment/infrastructure/scripts/update-env.sh

# Quick code sync
./deployment/infrastructure/scripts/quick-sync.sh
```

### Emergency Rollback
```bash
# List releases
ansible web_servers -i inventories/production/hosts.yml \
  -m shell -a "ls -la /home/deploy/michaelschiemer/releases/" \
  --vault-password-file .vault_pass

# Switch to previous release
ansible web_servers -i inventories/production/hosts.yml \
  -m shell -a "ln -sfn /home/deploy/michaelschiemer/releases/PREVIOUS_TIMESTAMP \
               /home/deploy/michaelschiemer/current" \
  --vault-password-file .vault_pass

# Restart containers
ansible web_servers -i inventories/production/hosts.yml \
  -m shell -a "cd /home/deploy/michaelschiemer/current && docker compose restart" \
  --vault-password-file .vault_pass
```
