fix: single container without nginx — Express serves frontend

Browse Source 
- Remove separate backend/ and frontend/ Dockerfiles
- Add root Dockerfile (3-stage: frontend build → backend build → runtime)
- Frontend static files served by Express from /public
- Simplify docker-compose to 3 services: mongodb, redis, app (port 3579)
- Fix vite proxy not to strip /api prefix from paths
- Default API URL to relative /api instead of hardcoded localhost

# 🐳 Podcastic - Unraid Installation Guide
# Podcastic - Unraid Installation Guide
Complete guide to install Podcastic on Unraid as a **single all-in-one container**.
Single container on port **3579** — includes backend, frontend, and serves everything via Express.
## 📋 What's Included
## What's Included
This single Docker container includes:
- ✅ **Backend**: Node.js + Express.js API
- ✅ **Frontend**: React web interface
- ✅ **Database**: MongoDB (embedded)
- ✅ **Cache**: Redis (embedded)
- ✅ **Web Server**: Nginx reverse proxy
- ✅ **Process Manager**: Supervisor (manages all 5 services)
All in **ONE container** on port **3579**
- **Backend**: Node.js + Express.js API
- **Frontend**: React web interface (served by Express as static files)
- **Database**: MongoDB (separate container, managed by Compose)
- **Cache**: Redis (separate container, managed by Compose)
## Prerequisites
- Unraid server with Docker support
- ~2GB RAM available
- ~20GB storage for database/media
- Internet connection
- Docker Compose (or Unraid's Compose Manager plugin)
## Installation Steps
## Installation
### Step 1: Clone Repository
```bash
# Via terminal on Unraid
cd /mnt/user/appdata # or your preferred path
cd /mnt/user/appdata
git clone https://github.com/R0m1k3/podcastic.git
cd podcastic
```
Or download as ZIP from GitHub and extract.
### Step 2: Configure Environment
```bash
# Copy template
cp .env.example .env
# Edit with your settings
nano .env
```
**Key settings**:
**Change at minimum:**
```env
NODE_ENV=production
# JWT Secret - CHANGE THIS!
JWT_SECRET=your-super-secret-key-change-me-in-production
# Optional: PodcastIndex API for podcast search
PODCAST_INDEX_API_KEY=
PODCAST_INDEX_API_SECRET=
JWT_SECRET=your-random-secret-here
```
### Step 3: Build Docker Image
### Step 3: Build and Start
Option A: Build locally (takes ~5-10 minutes)
```bash
docker-compose -f docker-compose.unraid.yml build --no-cache
docker-compose build --no-cache
docker-compose up -d
```
Option B: Use pre-built image (faster)
```bash
# Will be available after first push to Docker Hub
# docker pull r0m1k3/podcastic:latest
### Step 4: Access
Open: `http://your-unraid-ip:3579`
---
## Container Architecture
```
docker-compose services:
├── podcastic (port 3579)
│ ├── Express.js API → /api/*
│ └── React frontend → /* (static files)
├── podcastic-mongodb → internal :27017
└── podcastic-redis → internal :6379
```
### Step 4: Start Container
Only port **3579** is exposed externally.
---
## Data Persistence
Add volume mounts to `docker-compose.yml` for persistence:
```yaml
mongodb:
volumes:
- /mnt/user/appdata/podcastic/db:/data/db
redis:
volumes:
- /mnt/user/appdata/podcastic/redis:/data
```
---
## Management Commands
```bash
# Start
docker-compose -f docker-compose.unraid.yml up -d
# View logs
docker-compose -f docker-compose.unraid.yml logs -f podcastic
docker-compose logs -f app
# Check status
docker ps | grep podcastic
```
# Restart
docker-compose restart app
### Step 5: Access Application
# Stop all
docker-compose down
Open browser:
```
http://your-unraid-ip:3579
```
**First Time Setup**:
1. Click "Create Account"
2. Register with email/password
3. Log in
4. Go to "Discover" to search podcasts
5. Subscribe and listen!
---
## 📊 Container Architecture
```
Single Container (podcastic)
├── Nginx (port 3579)
│ ├── Serves static frontend
│ └── Proxies /api to backend
├── Node.js Backend (internal port 5000)
│ ├── API routes
│ ├── Authentication
│ └── Database management
├── MongoDB (internal port 27017)
│ └── Podcast data storage
└── Redis (internal port 6379)
└── Cache & sessions
```
All services communicate **internally** - only port 3579 exposed.

## 🛠️ Unraid Integration
### Add to Unraid via WebUI
1. **Settings → Docker** → Enable Docker
2. **Docker** tab
3. Add custom template:
```xml
<?xml version="1.0" encoding="utf-8"?>
<Container version="2">
<Name>podcastic</Name>
<Repository>r0m1k3/podcastic:latest</Repository>
<Registry>https://hub.docker.com/</Registry>

</Environment>
</Container>
```
Or use Docker Compose tab with `docker-compose.unraid.yml`
---
## 📂 Data Persistence
Data is saved to Unraid shares:
```
/mnt/user/appdata/podcastic/
├── db/ # MongoDB data (podcasts, users, episodes)
├── redis/ # Redis cache data
└── logs/ # Application logs
```
### Backup
```bash
# Backup database
docker exec podcastic mongodump --out /backup/mongodb
# Copy to safe location
cp -r /mnt/user/appdata/podcastic /mnt/backup/podcastic-backup
```
### Restore
```bash
docker exec podcastic mongorestore /backup/mongodb
```
---
## 🔧 Management Commands
### View Logs
```bash
# All logs
docker logs -f podcastic
# Specific service
docker exec podcastic tail -f /var/log/supervisor/backend.out.log
docker exec podcastic tail -f /var/log/supervisor/mongodb.out.log
docker exec podcastic tail -f /var/log/supervisor/redis.out.log
docker exec podcastic tail -f /var/log/supervisor/nginx.out.log
```
### Restart Container
```bash
docker-compose -f docker-compose.unraid.yml restart podcastic
```
### Stop Container
```bash
docker-compose -f docker-compose.unraid.yml down
# Keep volumes (data persists)
# Data in /mnt/user/appdata/podcastic/ is preserved
```
### Update to Latest
```bash
# Pull latest code
cd /path/to/podcastic
# Update
git pull
# Rebuild and restart
docker-compose -f docker-compose.unraid.yml build --no-cache
docker-compose -f docker-compose.unraid.yml up -d
docker-compose build --no-cache
docker-compose up -d
```
---
## 🐛 Troubleshooting
## Unraid WebUI Template
### Container won't start
Add via Docker > Add Container:
| Field | Value |
|-------|-------|
| Repository | (build from compose) |
| Port | 3579:3579 |
| Variable: JWT_SECRET | your-secret |
| Variable: MONGODB_URI | mongodb://podcastic-mongodb:27017/podcastic |
| Variable: REDIS_URL | redis://podcastic-redis:6379 |
Or use **Compose Manager plugin** with the `docker-compose.yml` from this repo.
---
## Troubleshooting
```bash
# Check logs
docker logs podcastic
# Check container status
docker-compose ps
# Common issues:
# - Port 3579 in use: Change in docker-compose.unraid.yml
# - Insufficient RAM: Free up memory
# - Permission issues: Check volume permissions
```
### MongoDB not starting
```bash
# Check mongo logs
docker exec podcastic tail -f /var/log/supervisor/mongodb.out.log
# Repair database
docker exec podcastic mongod --repair --dbpath /data/db
```
### Can't access on port 3579
```bash
# Check if container is running
docker ps | grep podcastic
# Check if port is open
netstat -tulpn | grep 3579
# Test connection
# Check health endpoint
curl http://localhost:3579/health
# Check API
curl http://localhost:3579/api/health
```
### Out of disk space
MongoDB can grow large. Check:
```bash
docker exec podcastic du -sh /data/db
# Clean old data (backup first!)
```
---
## 📈 Performance Optimization
### For Limited Resources
Edit `docker-compose.unraid.yml`:
```yaml
# Limit memory usage
mem_limit: 1g
cpus: '0.5'
```
### For High Performance
Increase limits:
```yaml
mem_limit: 4g
cpus: '2'
```
### Disable Unneeded Features
If only streaming (no search):
```env
PODCAST_INDEX_API_KEY= # Leave empty
```
---
## 🔒 Security Notes
### Change Default Secrets
```env
# MUST change in production!
JWT_SECRET=your-unique-secret-key-here
# Use strong password for first admin account
```
### Firewall Rules
Allow only trusted IPs:
```bash
# On Unraid, set firewall rules in UI
# Or use nginx config to restrict access
```
### SSL/HTTPS Setup
If exposing to internet, use reverse proxy with SSL:
- Nginx Proxy Manager (separate container)
- Traefik (with Let's Encrypt)
- Unraid built-in reverse proxy
---
## 📊 Monitoring
### Check Container Health
```bash
# Real-time stats
docker stats podcastic
# Service status
docker exec podcastic supervisorctl status
# Expected output:
# mongodb RUNNING pid 123, uptime 0:00:45
# redis RUNNING pid 124, uptime 0:00:45
# backend RUNNING pid 125, uptime 0:00:45
# nginx RUNNING pid 126, uptime 0:00:45
```
### Resource Usage
```bash
# Disk usage
du -sh /mnt/user/appdata/podcastic/
# Memory usage
docker exec podcastic free -h
# CPU usage
docker stats --no-stream podcastic
```
---
## 🆘 Support
If issues occur:
1. **Check logs**:
```bash
docker logs podcastic
```
2. **Check service status**:
```bash
docker exec podcastic supervisorctl status
```
3. **Rebuild container**:
```bash
docker-compose -f docker-compose.unraid.yml build --no-cache
docker-compose -f docker-compose.unraid.yml up -d
```
4. **Factory reset** (loses all data!):
```bash
docker-compose -f docker-compose.unraid.yml down -v
rm -rf /mnt/user/appdata/podcastic
# Start fresh
```
---
## 🎯 Next Steps
1. **First Run**: Create account, set JWT_SECRET properly
2. **Configure PodcastIndex**: Optional, enables podcast search
3. **Add Podcasts**: Via Discover or RSS URLs
4. **Enjoy**: Start listening!
