Docker Deployment#

Basic Commands#

# Build and run with specific environment
docker-compose --env-file .env.development up --build   # Development
docker-compose --env-file .env.staging up --build       # Staging
docker-compose --env-file .env.production up --build    # Production

# Run in detached mode
docker-compose --env-file .env.production up -d --build

# Stop containers
docker-compose down

# View logs
docker-compose logs -f

Override Single Variables#

VITE_API_URL=https://custom-domain.com docker-compose up --build

Using Docker Compose Override Files#

Development (docker-compose.dev.yml)#

services:
  app:
    build:
      args:
        VITE_API_URL: http://localhost:3000
        NODE_ENV: development
        RUST_ENV: debug
    volumes:
      - ./src:/usr/src/app/src
    environment:
      RUST_LOG: debug

Production (docker-compose.prod.yml)#

services:
  app:
    build:
      args:
        VITE_API_URL: https://your-production-domain.com
        NODE_ENV: production
        RUST_ENV: release
    deploy:
      replicas: 2
    logging:
      driver: "json-file"
      options:
        max-size: "10m"
        max-file: "3"

Using Override Files#

# Development
docker-compose -f docker-compose.yml -f docker-compose.dev.yml up --build

# Production
docker-compose -f docker-compose.yml -f docker-compose.prod.yml up --build

Environment Variables Reference#

Build-time Variables#

• VITE_API_URL: Frontend API endpoint
• NODE_ENV: Node.js environment (development/production)
• RUST_ENV: Rust build type (debug/release)

Runtime Variables#

• SERVER_HOST: Backend host address
• SERVER_PORT: Backend port
• JWT_SECRET: JWT signing key
• RUST_LOG: Logging level
• DATABASE_URL: PostgreSQL connection string

Database Variables#

• POSTGRES_DB: Database name
• POSTGRES_USER: Database user

Container Structure#

Frontend Container#

• Build tool: Bun
• Source: /app/frontend
• Output: /app/frontend/dist
• Static files location: /app/static

Backend Container#

• Build tool: Cargo
• Source: /usr/src/app
• Binary: /app/simplelink
• Migrations: /app/migrations

Production Deployment Checklist#

1. Environment Setup

   • Set secure database passwords
   • Generate strong JWT secret
   • Configure proper API URL
   • Set appropriate logging levels

2. Database

   • Configure backup strategy
   • Set up proper indexes
   • Configure connection pooling

3. Security

   • Enable SSL/TLS
   • Set up proper firewalls
   • Configure CORS properly
   • Use secrets management

4. Monitoring

   • Set up logging aggregation
   • Configure health checks
   • Set up metrics collection

5. Performance

   • Configure proper cache headers
   • Set up CDN if needed
   • Configure database connection pool size

Common Operations#

View Container Logs#

# All containers
docker-compose logs -f

# Specific container
docker-compose logs -f app
docker-compose logs -f db

Access Database#

# Connect to database container
docker-compose exec db psql -U shortener -d shortener

# Backup database
docker-compose exec db pg_dump -U shortener shortener > backup.sql

# Restore database
cat backup.sql | docker-compose exec -T db psql -U shortener -d shortener

Container Management#

# Restart single service
docker-compose restart app

# View container status
docker-compose ps

# View resource usage
docker-compose top

Troubleshooting#

Database Connection Issues#

1. Check if database container is running:

   docker-compose ps db
   

2. Verify database credentials in environment files
3. Check database logs:

   docker-compose logs db
   

Frontend Build Issues#

1. Clear node_modules and rebuild:

   docker-compose down
   rm -rf frontend/node_modules
   docker-compose up --build
   

Backend Issues#

1. Check backend logs:

   docker-compose logs app
   

2. Verify environment variables are set correctly
3. Check database connectivity

Build Script Usage#

The build.sh script handles environment-specific builds and static file generation.

Basic Usage#

# Default production build
./build.sh

# Development build
ENV=development ./build.sh

# Staging build
ENV=staging ./build.sh

# Production build with custom API URL
VITE_API_URL=https://api.example.com ./build.sh

# Development build with custom API URL
ENV=development VITE_API_URL=http://localhost:8080 ./build.sh

# Show help
./build.sh --help
