Nginx Configuration Patterns

Standard Nginx Setup:

volumes:
  # Main configuration
  - nginx.conf:/etc/nginx/nginx/nginx.conf:ro
  # Virtual host configuration
  - default.conf:/etc/nginx/conf.d/default.conf:ro
  # Web content
  - web-content:/usr/share/nginx/html:ro

Environment Separation:

• Production:/mnt/swarm-data/webservers/production/
• Testing:/mnt/swarm-data/webservers/testing/
• Web Files: Separate directory structure for content
