# Sigvild Gallery Deployment Guide

## Overview

Sigvild Wedding Gallery is deployed on **mini-vps** (production environment) for high uptime and reliability. The gallery uses PocketBase API backend with SvelteKit frontend.

**Production Host**: mini-vps (72.62.91.251)  
**Domains**: sigvild.no (frontend), api.sigvild.no (API)

## Quick Start

Deploy Sigvild Gallery to production:

```bash
ansible-playbook playbooks/production.yml
```

## Prerequisites Setup

### 1. Vault Password Configuration

Encrypted passwords are stored in `group_vars/production/vault.yml`:

```bash
# Edit production vault (run from rick-infra directory)
ansible-vault edit group_vars/production/vault.yml
```

Add these variables:

```yaml
# Production vault variables
vault_cloudflare_api_token: "your-cloudflare-token"
vault_caddy_tls_email: "admin@example.com"
vault_sigvild_host_password: "host-user-password"
vault_sigvild_guest_password: "guest-user-password"
vault_pb_su_email: "admin@sigvild.no"
vault_pb_su_password: "admin-password"
```

**Note**: Use `ansible-vault encrypt group_vars/production/vault.yml` after editing.

### 2. DNS Configuration

Point these domains to **mini-vps** (72.62.91.251):
- `sigvild.no` A record → 72.62.91.251
- `api.sigvild.no` A record → 72.62.91.251

### 3. Project Structure

Ensure the sigvild-gallery project is adjacent to rick-infra:

```
~/
├── rick-infra/          # This repository
└── sigvild-gallery/     # Sigvild gallery project
    ├── build_tmp/       # Production builds
    ├── sigvild-kit/     # Frontend source
    └── main.go          # Backend source
```

## Deployment Commands

### Production Deployment

Deploy to production environment (mini-vps):

```bash
# Deploy complete production stack (Caddy + Sigvild Gallery)
ansible-playbook playbooks/production.yml

# Or deploy everything with production limit
ansible-playbook site.yml -l production
```

### Selective Updates

Update specific components using tags:

```bash
# Frontend only (quick static file updates)
ansible-playbook playbooks/production.yml --tags="frontend"

# Backend only (API service updates)  
ansible-playbook playbooks/production.yml --tags="backend"

# Caddy configuration only
ansible-playbook playbooks/production.yml --tags="caddy"

# Just build process (development)
ansible-playbook playbooks/production.yml --tags="build"
```

### Backup and Restore

Create backups before major changes:

```bash
# Create backup (works on any host running sigvild-gallery)
ansible-playbook playbooks/backup-sigvild.yml -l mini-vps

# Backup is saved to: ~/sigvild-gallery-backup/
```

**Automatic Restore**: When deploying to a fresh server, the role automatically detects and restores from the latest backup if available.

## Architecture Overview

**Production Environment**: mini-vps (72.62.91.251)

```
Internet
    ↓
Cloudflare DNS → mini-vps
    ↓
Caddy (Auto HTTPS with DNS Challenge)
    ├── sigvild.no → /var/www/sigvild-gallery/ (Static Files)
    └── api.sigvild.no → localhost:8090 (PocketBase API)
            ↓
        Go Binary (/opt/sigvild-gallery/sigvild-gallery)
            ↓
        SQLite Database (/opt/sigvild-gallery/pb_data/)
            └── File Storage (wedding photos)
```

**Key Features**:
- Automatic HTTPS with Let's Encrypt
- Cloudflare DNS challenge for certificate validation
- Security headers and CORS protection
- SystemD service management
- Automatic backup/restore capability

## Service Management

### Status Checks

```bash
# Check services on mini-vps
ansible mini-vps -a "systemctl status sigvild-gallery"
ansible mini-vps -a "systemctl status caddy"

# View gallery logs
ansible mini-vps -a "journalctl -u sigvild-gallery -n 50 --no-pager"

# View Caddy logs
ansible mini-vps -a "journalctl -u caddy -n 20 --no-pager"

# Check data directory
ansible mini-vps -a "ls -lh /opt/sigvild-gallery/pb_data/"
```

### Manual Operations

```bash
# Restart gallery service
systemctl restart sigvild-gallery

# Reload Caddy configuration
systemctl reload caddy

# Check API health
curl https://api.sigvild.no/api/health
```

## Troubleshooting

### Build Issues

**Problem**: Go build fails
```bash
# Ensure Go is installed locally
go version

# Check if you're in the right directory
ls sigvild-gallery/main.go
```

**Problem**: Frontend build fails  
```bash
# Check Node.js and npm
node --version && npm --version

# Ensure dependencies are installed
cd sigvild-gallery/sigvild-kit
npm install
```

### Service Issues

**Problem**: Service won't start
```bash
# Check service status
systemctl status sigvild-gallery

# Check service logs
journalctl -u sigvild-gallery --no-pager

# Verify binary permissions
ls -la /opt/sigvild-gallery/sigvild-gallery-server
```

**Problem**: Database permissions
```bash
# Check data directory ownership
ls -la /opt/sigvild-gallery/data/

# Fix ownership if needed
sudo chown -R sigvild:sigvild /opt/sigvild-gallery/
```

### Network Issues

**Problem**: Domain not resolving
```bash
# Test DNS resolution
dig sigvild.no
dig api.sigvild.no

# Test local connectivity
curl -H "Host: sigvild.no" http://localhost
curl -H "Host: api.sigvild.no" http://localhost
```

**Problem**: HTTPS certificate issues
```bash
# Check Caddy logs for ACME errors
journalctl -u caddy | grep -i "acme\|certificate"

# Verify DNS challenge credentials
# (Check Cloudflare API token in vault)
```

## Security Features

### Environment Protection
- **No .env files**: Secrets stored in systemd environment variables only
- **Vault encryption**: All passwords encrypted with ansible-vault
- **Memory isolation**: Secrets only exist in process memory

### SystemD Sandboxing
- **Read-only filesystem**: Application cannot modify system files
- **Isolated temporary**: Private /tmp directory
- **Limited capabilities**: No privilege escalation possible
- **Data directory only**: Write access restricted to /opt/sigvild-gallery/data/

### Web Security
- **Automatic HTTPS**: Let's Encrypt certificates via DNS challenge
- **Security headers**: XSS protection, frame options, content type sniffing prevention
- **CORS restrictions**: API access limited to frontend domain
- **Rate limiting**: API endpoint protection

## File Locations (on mini-vps)

## Next Steps After Deployment

1. **Verify services**: Check that both domains are accessible
2. **Test authentication**: Login with host/guest credentials
3. **Upload test photo**: Verify file upload functionality
4. **Monitor logs**: Watch for any errors in service logs
5. **Backup setup**: Configure regular database backups

## Development Workflow

For ongoing development:

```bash
# 1. Make changes to sigvild-gallery project
cd ~/sigvild-gallery

# 2. Test locally  
go run . serve &
cd sigvild-kit && npm run dev

# 3. Deploy updates to production
cd ~/rick-infra
ansible-playbook playbooks/production.yml --tags="sigvild"
```

**Build Process**:
- Backend: Built locally with `GOOS=linux GOARCH=amd64 go build`
- Frontend: Built locally with `npm run build` in sigvild-kit/
- Assets transferred to mini-vps via Ansible
- No build tools required on the server

## Migration History

**December 2025**: Migrated from arch-vps (homelab) to mini-vps (production)
- **Reason**: Client project requiring higher uptime reliability
- **Method**: Backup from arch-vps, automatic restore to mini-vps
- **Downtime**: ~5 minutes during DNS propagation
- **Previous host**: arch-vps (69.62.119.31)
- **Current host**: mini-vps (72.62.91.251)
