This guide covers deployment options for self-hosted Onetime Secret instances.

Deployment Options

Docker Deployment

Docker provides the most reliable and portable deployment method.

Using Docker Compose

For complete infrastructure management, use the dedicated Docker Compose repository:

Repository: https://github.com/onetimesecret/docker-compose/

Quick setup:

git clone https://github.com/onetimesecret/docker-compose.git
cd docker-compose
docker-compose up -d

Manual Docker Compose setup:

version: '3.8'

services:
  onetime:
    image: onetimesecret/onetimesecret:latest
    ports:
      - "3000:3000"
    environment:
      - REDIS_URL=redis://redis:6379/0
      - SECRET=${SECRET}
      - HOST=${HOST:-localhost:3000}
      - SSL=${SSL:-false}
      - RACK_ENV=production
    depends_on:
      - redis
    volumes:
      - ./etc:/app/etc
      - ./logs:/app/logs

  redis:
    image: redis:bookworm
    volumes:
      - redis_data:/data
    command: redis-server --requirepass ${REDIS_PASSWORD}

volumes:
  redis_data:

Environment file (.env):

SECRET=your-secure-32-character-hex-key
REDIS_PASSWORD=your-redis-password
HOST=your-domain.com
SSL=true

Manual Installation

For environments requiring custom configurations or existing infrastructure.

Reverse Proxy Configuration

These configuration examples can help you get started, but you should adjust them to fit your specific needs.

Nginx

Basic Configuration:

server {
    listen 80;
    server_name your-domain.com;
    return 301 https://$server_name$request_uri;
}

server {
    listen 443 ssl http2;
    server_name your-domain.com;

    # SSL Configuration
    ssl_certificate /path/to/your/cert.pem;
    ssl_certificate_key /path/to/your/key.pem;
    ssl_protocols TLSv1.2 TLSv1.3;
    ssl_ciphers ECDHE-RSA-AES256-GCM-SHA512:DHE-RSA-AES256-GCM-SHA512;

    # Security headers
    add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;
    add_header X-Frame-Options DENY always;
    add_header X-Content-Type-Options nosniff always;

    # Static files from built frontend
    location /dist/ {
        root /app/public;
        expires 1y;
        add_header Cache-Control "public, immutable";
        try_files $uri $uri/ =404;
    }

    # API requests to backend
    location /api/ {
        proxy_pass http://127.0.0.1:3000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }

    # All other requests to backend
    location / {
        proxy_pass http://127.0.0.1:3000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;

        # WebSocket support
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}

Enable the site:

sudo ln -s /etc/nginx/sites-available/onetime /etc/nginx/sites-enabled/
sudo nginx -t
sudo systemctl reload nginx

Caddy

Caddy provides automatic HTTPS and simpler configuration:

your-domain.com {
    # Handle static files from built frontend
    handle /dist/* {
        root * /app/public
        file_server
    }

    # API requests to backend
    handle /api/* {
        reverse_proxy 127.0.0.1:3000
    }

    # All other requests to backend (for server-rendered pages)
    handle {
        reverse_proxy 127.0.0.1:3000
    }
}

Apache

<VirtualHost *:80>
    ServerName your-domain.com
    Redirect permanent / https://your-domain.com/
</VirtualHost>

<VirtualHost *:443>
    ServerName your-domain.com

    # SSL Configuration
    SSLEngine on
    SSLCertificateFile /path/to/your/cert.pem
    SSLCertificateKeyFile /path/to/your/key.pem

    # Security headers
    Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains"
    Header always set X-Frame-Options DENY
    Header always set X-Content-Type-Options nosniff

    # Static files from built frontend
    Alias /dist /app/public/dist
    <Directory /app/public/dist>
        Require all granted
        ExpiresActive On
        ExpiresDefault "access plus 1 year"
    </Directory>

    # API and app requests to backend
    ProxyPreserveHost On
    ProxyPass /dist !
    ProxyPass / http://127.0.0.1:3000/
    ProxyPassReverse / http://127.0.0.1:3000/
</VirtualHost>

SSL/TLS Configuration

Let’s Encrypt (Certbot)

Install Certbot:

# Ubuntu/Debian
sudo apt install certbot python3-certbot-nginx

# CentOS/RHEL
sudo dnf install certbot python3-certbot-nginx

Generate Certificate:

# For Nginx
sudo certbot --nginx -d your-domain.com

# For Apache
sudo certbot --apache -d your-domain.com

# Manual certificate (if using custom proxy config)
sudo certbot certonly --webroot -w /var/www/html -d your-domain.com

Auto-renewal:

# Add to crontab
echo "0 12 * * * /usr/bin/certbot renew --quiet" | sudo tee -a /etc/crontab

Custom SSL Certificates

Place your certificates and update paths in proxy configuration:

# Certificate files
/etc/ssl/certs/your-domain.com.crt
/etc/ssl/private/your-domain.com.key

# Set proper permissions
sudo chmod 600 /etc/ssl/private/your-domain.com.key
sudo chmod 644 /etc/ssl/certs/your-domain.com.crt

Redis Configuration

Option 1: Memory-only (never save to disk for maximum security):

# Memory optimization
maxmemory 1gb
maxmemory-policy allkeys-lru

# Security - secrets never written to disk
save ""  # Disable all automatic saves
appendonly no  # Disable AOF logging

# Security
requirepass your_redis_password
bind 127.0.0.1

# Performance
tcp-keepalive 60
timeout 300

Option 2: Disk persistence (enables backups but writes secrets to disk):

# Memory optimization
maxmemory 1gb
maxmemory-policy allkeys-lru

# RDB snapshots - creates dump.rdb files
save 900 1    # Save if at least 1 key changed in 900 seconds
save 300 10   # Save if at least 10 keys changed in 300 seconds
save 60 10000 # Save if at least 10000 keys changed in 60 seconds

# AOF logging - creates appendonly.aof files for point-in-time recovery
appendonly yes
appendfsync everysec  # Sync to disk every second

# Security
requirepass your_redis_password
bind 127.0.0.1

# Performance
tcp-keepalive 60
timeout 300

Important: With disk persistence enabled, secrets will be written to:

dump.rdb files (snapshots at intervals)
appendonly.aof files (continuous append log)

Choose based on your security vs. backup requirements.

Restart Redis:

sudo systemctl restart redis

Redis Backups

Redis:

#!/bin/bash
# Redis backup script
BACKUP_DIR="/var/backups/onetime"
DATE=$(date +%Y%m%d_%H%M%S)

mkdir -p $BACKUP_DIR

# Create backup
redis-cli -a "$REDIS_PASSWORD" --rdb $BACKUP_DIR/redis_$DATE.rdb

# Cleanup old backups
find $BACKUP_DIR -name "redis_*.rdb" -mtime +7 -delete

Next Steps

After successful deployment:

Configure your instance with custom settings
Set up monitoring and alerting for production operations
Review security settings and enable additional protections
Configure backup automation and test recovery procedures
Set up custom domains for your organization

Your Onetime Secret instance is now ready for production use!
