|
|
- **Benefit**: Creates a standalone Next.js build optimized for containers
|
|
|
|
## ✅ Issues Fixed
|
|
|
|
### 🚨 **Critical Build Issues RESOLVED**
|
|
|
|
#### 1. **Dependency Installation Problem**
|
|
- **Issue**: Using `npm ci --only=production` during build phase
|
|
- **Problem**: Next.js build requires devDependencies (TypeScript, Tailwind, Prisma CLI)
|
|
- **Fix**: Install all dependencies during build, production-only in final image
|
|
|
|
#### 2. **Prisma Migration Failures**
|
|
- **Issue**: Prisma CLI not available for migrations
|
|
- **Problem**: Separate migration service wouldn't work in Portainer
|
|
- **Fix**: Integrated migrations into app startup with Prisma CLI included
|
|
|
|
#### 3. **Health Check Failures**
|
|
- **Issue**: Using `curl` command without installing curl
|
|
- **Problem**: Alpine images don't include curl by default
|
|
- **Fix**: Explicitly install curl in Dockerfile
|
|
|
|
#### 4. **Portainer Compatibility Issues**
|
|
- **Issue**: Migration service using local file mounts
|
|
- **Problem**: Portainer can't access local files like `./prisma`
|
|
- **Fix**: Removed separate migration service, integrated into main app
|
|
|
|

|
## How Migrations Work Now ✅
|
|
|
|
### **Startup Process:**
|
|
1. Container starts
|
|
2. **Runs database migrations automatically**
|
|
3. Starts Next.js application
|
|
4. Health checks begin
|
|
|
|
### **Migration Command:**
|
|
```bash
|
|
npx prisma migrate deploy || echo "Migration failed, but continuing..."
|
|
```
|
|
|
|
### **Logs to Monitor:**
|
|
```bash
|
|
docker logs taskboard-app
|
|
# Will show:
|
|
# Running database migrations...
|
|
# Environment variables loaded from .env
|
|
# Prisma schema loaded from prisma/schema.prisma
|
|
# Starting application...
|
|
```
|
|
|
|
## Networks
|
|
- `nginx-proxy-manager_default`: External network for proxy access
|
|
- `taskboard-network`: Internal network for app-database communication
|
|
|
|
## Volumes
|
|
- `postgres_data`: PostgreSQL data persistence
|
|
- `app_uploads`: File uploads storage
|
|
- `app_logs`: Application logs storage
|
|
|
|
## Deployment Process ✅ **SIMPLIFIED**
|
|
|
|
```bash
|
|
# 1. Build image
|
|
docker build -t yourusername/taskboard:latest .
|
|
|
|
# 2. Push to Docker Hub
|
|
docker login
|
|
docker push yourusername/taskboard:latest
|
|
|
|
# 3. Deploy in Portainer
|
|
# - Copy portainer-stack.yml content
|
|
# - Set environment variables
|
|
# - Deploy stack
|
|
|
|
# 4. Verify
|
|
docker logs taskboard-app # Check migration logs
|
|
curl https://yourdomain.com/api/health # Test health
|
|
```
|
|
|
|
