Capsule Budget - ZimaOS Deployment Guide

Quick Deploy

1. Clone or upload this repository to your ZimaOS device

2. Run the deployment script:

   ./deploy.sh
   

   This will:

   • Generate a secure encryption key
   • Clear any test data
   • Build the Docker image
   • Start the container

3. Access Capsule:

   • Open browser to http://your-zima-ip:7654
   • Create your account and start budgeting!

Manual Deployment

If you prefer manual setup:

1. Create .env file:

   cp .env.example .env
   

2. Generate encryption key:

   openssl rand -base64 32
   

3. Update .env with your key:

   ENCRYPTION_KEY=your-generated-key-here
   

4. Build and start:

   docker-compose up -d
   

Data Persistence

IMPORTANT: Your data is safely stored outside the Docker container

How It Works

The Docker setup uses a bind mount to persist data:

volumes:
  - ./data:/app/data  # Host directory : Container directory

• Host Location: ./data/ (on your ZimaOS filesystem)
• Container Location: /app/data/ (inside the container)
• What's Stored:
  • User credentials (hashed)
  • Budget data (encrypted)
  • Transaction history
  • Envelope configurations

Data Survives

✅ Container restarts
✅ Container rebuilds
✅ Docker Compose down/up
✅ System reboots (with restart: unless-stopped)

Data is Lost If

❌ You delete the ./data directory
❌ You run docker-compose down -v (removes volumes)

Testing Persistence

Run the included test script:

./test-persistence.sh

This verifies that:

1. Data directory is correctly mounted
2. Files created in container appear on host
3. Data survives container restarts

Backup Your Data

Recommended backup schedule:

# Quick backup
cp -r data data-backup-$(date +%Y%m%d)

# Compressed backup
tar -czf capsule-backup-$(date +%Y%m%d).tar.gz data/

# Restore from backup
tar -xzf capsule-backup-YYYYMMDD.tar.gz

Using ZimaOS:

• Enable automatic snapshots for the Capsule directory
• Or use ZimaOS built-in backup features

Data Location on ZimaOS

Depending on where you deploy:

• SMB/File Manager: Check the upload location
• SSH Deployment: Usually /mnt/your-pool/apps/capsule/data
• Docker Apps: May be in /var/lib/docker/volumes/

To find exact location:

docker inspect capsule-budget | grep -A 10 "Mounts"

ZimaOS Integration

Using ZimaOS Apps

If ZimaOS supports custom apps:

1. Navigate to Apps section
2. Click "Add Custom App"
3. Point to this directory
4. Configure port: 7654

Using ZimaOS File Manager

1. Upload project via web interface or SMB
2. SSH into ZimaOS
3. Navigate to project directory
4. Run ./deploy.sh

Data Persistence

All user data is stored in ./data/ directory:

• User credentials (hashed)
• Budget data (encrypted with AES-GCM)
• Transaction history

Backup Strategy:

# Backup data
cp -r data data-backup-$(date +%Y%m%d)

# Or use ZimaOS snapshot feature

Management Commands

# View logs
docker-compose logs -f

# Stop Capsule
docker-compose stop

# Restart Capsule
docker-compose restart

# Stop and remove container
docker-compose down

# Rebuild after updates
docker-compose build --no-cache
docker-compose up -d

Updating Capsule

# Pull latest changes
git pull

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

Your data in ./data/ will persist across updates.

Security Notes

• Change the default ENCRYPTION_KEY before first use
• Keep your .env file secure and never commit it
• Use ZimaOS firewall to restrict access if needed
• Consider VPN-only access for additional security

Troubleshooting

Container won't start

# Check logs
docker-compose logs

# Verify .env file exists
ls -la .env

Port already in use

Edit docker-compose.yml and change port mapping:

ports:
  - "8080:7654"  # Change 8080 to your preferred port

Data not persisting

Ensure ./data directory has correct permissions:

chmod 755 data
