如何dockerize Ruby on Rails的生产？

我使用Docker为我的开发环境设置了Ruby on Rails，但我不确定此configuration是否适合生产。 目前我使用nginx +独angular兽作为networking服务器，但nginx +乘客或nginx +美洲狮呢？

我告诉你我的docker设置，希望你有一些改进。

泊坞窗，compose.yml

web: image: nginx:latest ports: - "80" - "443" links: - "rails" environment: VIRTUAL_HOST: blog.dev.lvh volumes: - ./log/nginx:/var/log/nginx - ./docker/nginx/nginx.conf:/etc/nginx/nginx.conf - ./docker/nginx/sites-enabled:/etc/nginx/sites-enabled - ./docker/nginx/ssl:/etc/nginx/ssl volumes_from: - rails rails: image: mc388/rails:latest environment: RACK_ENV: development RAILS_ENV: development command: bundle exec unicorn -c config/unicorn.rb volumes: - ./:/var/www/html links: - mysql mysql: image: mysql:latest volumes: - ./mysql/dev:/var/lib/mysql environment: MYSQL_ROOT_PASSWORD: somepw MYSQL_DATABASE: mablen_dev 

nginx.conf

 user nginx; worker_processes 1; pid /var/run/nginx.pid; events { worker_connections 1024; } http { include /etc/nginx/mime.types; default_type application/octet-stream; #default_type text/html; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; error_log /var/log/nginx/error.log warn; sendfile on; keepalive_timeout 65; include /etc/nginx/sites-enabled/*; } 

网站-endable / rails.conf
