# 🐳 Docker Deployment Guide for Image Storage

This guide covers deployment of the HomeBase image storage system in Docker on your home lab.

## Prerequisites

- Docker and Docker Compose installed on your home lab server (beepc)
- SSH access configured (required for deploy script)
- PowerShell 5+ or PowerShell Core for running deploy scripts
- Network access from your dev machine to the home lab

## Quick Deployment

### 1. Deploy to Home Lab

From your local machine, run:

```powershell
.\scripts\deploy.ps1
```

This script will:
- Copy all project files to your home lab server (spencer@beepc)
- Build the Docker image
- Create and start the container with persistent storage
- Set up systemd service for auto-start

### 2. After Deployment

The container will automatically:
- Create the SQLite database
- Create image storage directories
- Start the image fetcher (if configured)
- Be available at `http://homebase.sketchferret.com`

## Docker Setup Details

### Persistent Storage

Images are stored in a Docker volume called `homebase-data`:

```yaml
volumes:
  - homebase-data:/app/data
```

This ensures:
- Database persists across container restarts
- Image files are not lost on container recreation
- Data survives container updates

### Viewing Container Logs

```bash
# SSH into home lab
ssh spencer@beepc

# View container logs
docker compose -f ~/homebase/docker-compose.yml logs -f

# Or use systemd
journalctl -u homebase -f
```

### Container Management

```bash
# Stop container
docker compose -f ~/homebase/docker-compose.yml down

# Rebuild and restart
docker compose -f ~/homebase/docker-compose.yml up -d --build

# Check status
docker compose -f ~/homebase/docker-compose.yml ps

# View stored images
docker exec homebase ls -lh /app/data/images/
```

## Configuration in Docker

### Image Sources (image-sources.json)

After deployment, edit the configuration on the remote server:

```bash
ssh spencer@beepc
nano ~/homebase/image-sources.json
```

Then restart the container:

```bash
cd ~/homebase
docker compose restart app
```

### Environment Variables

Edit `docker-compose.yml` to customize:

```yaml
environment:
  - NODE_ENV=production
  - PORT=3001
  - DOMAIN=homebase.sketchferret.com
```

## Managing Data

### Backup Database

The SQLite database is stored in the Docker volume at `/app/data/homebase.db`

```bash
# SSH into server
ssh spencer@beepc

# Backup database
docker run --rm -v homebase-data:/data \
  -v ~/backups:/backup \
  alpine cp /data/homebase.db /backup/homebase.db.$(date +%Y%m%d)

# Backup images
docker run --rm -v homebase-data:/data \
  -v ~/backups:/backup \
  alpine tar czf /backup/images.$(date +%Y%m%d).tar.gz /data/images/
```

### Restore Database

```bash
docker run --rm -v homebase-data:/data \
  -v ~/backups:/backup \
  alpine cp /backup/homebase.db.20260211 /data/homebase.db

# Restart container
docker restart homebase
```

### Clean Up Old Images

```bash
# SSH into server
ssh spencer@beepc

# Connect to running container
docker exec -it homebase node -e "
const db = require('./lib/database');
db.initializeDatabase().then(async () => {
  const deleted = await db.cleanupOldImages(30);
  console.log('Deleted', deleted, 'old images');
  process.exit(0);
}).catch(err => {
  console.error(err);
  process.exit(1);
});
"
```

## Troubleshooting

### Container won't start

```bash
ssh spencer@beepc
cd ~/homebase

# Check logs
docker compose logs app

# Rebuild
docker compose up -d --build

# Check again
docker compose ps
```

### Permission errors

The container runs as the `node` user. Check logs:

```bash
docker compose exec app ls -la /app/data/
```

All files should be owned by `node`.

### Can't access via domain

Check that the service is running:

```bash
ssh spencer@beepc

# Check systemd
systemctl status homebase

# Check Docker
docker ps | grep homebase

# Test port
curl -i http://localhost:3001/health
```

### Database is locked

This usually means two processes are accessing the database simultaneously:

```bash
# Check if multiple containers are running
docker ps -a | grep homebase

# Stop all containers
docker compose down

# Verify only one is running
docker compose up -d
```

## Updating the Deployment

### Update Code

After making changes locally:

```powershell
cd c:\Users\srene\Sources\HomeBase
git commit -am "Add new features"
git push

# Deploy to home lab
.\scripts\deploy.ps1
```

### Update Dependencies

If you update `package.json`:

```powershell
# From your local machine
.\scripts\deploy.ps1

# The deploy script will:
# 1. Copy new package.json
# 2. Rebuild the Docker image (npm install runs here)
# 3. Restart the container
```

### Manual Updates

SSH into the server and run:

```bash
cd ~/homebase

# Pull latest code
git pull  # If using git

# Or manually copy files via SCP
# Then rebuild:
docker compose up -d --build
```

## Systemd Service

The deployment script sets up a systemd service:

```bash
# Check service
systemctl status homebase

# Start service
sudo systemctl start homebase

# Stop service
sudo systemctl stop homebase

# View logs
journalctl -u homebase -f
```

Service file location: `/etc/systemd/system/homebase.service`

## Volume Management

### List volumes

```bash
docker volume ls | grep homebase
```

### Inspect volume

```bash
docker volume inspect homebase-data
```

Shows the mount point on the host server.

### Manual mount (for recovery)

```bash
docker run -it --rm -v homebase-data:/data alpine sh
```

Then you can inspect files at `/data/`

## Performance Optimization

### Monitor Storage Usage

```bash
curl http://homebase.sketchferret.com/api/stats
```

### Cleanup Recommendations

- **Weekly**: Run cleanup for images older than 7 days
- **Monthly**: Run verification to check corruption
- **Quarterly**: Full database optimization

```bash
# SSH into server
ssh spencer@beepc
docker exec homebase node -e "
const db = require('./lib/database');
const storage = require('./lib/storage');

db.initializeDatabase().then(async () => {
  console.log('Running cleanup...');
  const deleted = await db.cleanupOldImages(7);
  const orphaned = await storage.cleanupOrphanedFiles(db.db);
  console.log('Deleted:', deleted, 'old images');
  console.log('Removed:', orphaned.cleaned, 'orphaned files');
  process.exit(0);
}).catch(err => {
  console.error('Error:', err);
  process.exit(1);
});
"
```

## Network & Firewall

### Open Ports

Ensure port 3001 is accessible on your home lab network:

```bash
# Check if port is listening
ssh spencer@beepc
netstat -tlnp | grep 3001

# Or use Docker
docker port homebase
```

### Domain Configuration

The app is configured to run on `homebase.sketchferret.com`. Ensure:
- DNS resolves to your home lab IP
- Firewall allows traffic on port 3001
- Your home lab router has port forwarding (if external access needed)

## Debugging

### Enable detailed logging

```bash
# SSH into server
ssh spencer@beepc

# View container logs with timestamps
docker compose logs -f --timestamps app

# Or view the last 100 lines
docker compose logs --tail=100 app
```

### Access container shell

```bash
docker exec -it homebase sh
cd /app
node setup.js config
```

### Database inspection

```bash
# Access SQLite directly
docker exec -it homebase sqlite3 /app/data/homebase.db

# In sqlite prompt:
sqlite> SELECT COUNT(*) FROM images;
sqlite> SELECT * FROM tags;
sqlite> .quit
```

## Best Practices

1. **Regular Backups**: Back up the database volume weekly
2. **Log Monitoring**: Check logs regularly for errors
3. **Storage Limits**: Monitor storage and clean up old images
4. **Configuration**: Keep `image-sources.json` updated with working URLs
5. **Testing**: Test image fetching after configuration changes
