【问题】VirtualBox和Vmware中宿主机挂载文件夹到虚拟机有什么不同？

为了可追溯，我把question提取出来整理成文章，方便自己以后对问题进行追溯。

我之前一直是Docker ToolBox套装做的docker学习环境，后面直接使用compose构建了许多开发环境和单机生产环境，但是出现过很多莫名其妙的问题。

VirtualBox 使用Boot2Docker共享文件夹开发，js修改后尾部出现一串乱码(和nginx容器都没关系)

Docker-compose.yml

version:  '3.0'
services:
##基础环境
  nginx:
    image: nginx:1.13.3
    volumes:
      - /etc/localtime:/etc/localtime:ro
#网站目录
      - ./app:/var/www/html
      - ./dockerfiles/nginx/conf.d:/etc/nginx/conf.d:ro
#日志文件
      - ./logs/nginx:/var/log/nginx
    links:
      - "php-fpm:php-fpm"
    ports:
      - "80:80"
    command: nginx -g 'daemon off;'

  mysql-db:
    image: mysql:5.5
#很重要导入到处数据
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - ./data/mysql:/var/lib/mysql:rw
      - ./logs/mysql:/var/lib/mysql-logs:rw
      - ./dockerfiles/mysql/conf.d:/etc/mysql/conf.d:ro
    environment:
        MYSQL_ROOT_PASSWORD: zhaojun
        MYSQL_DATABASE: lottery_api_sale
        MYSQL_USER: zhaojun
        MYSQL_PASSWORD: zhaojun
    ports:
      - "3306:3306"
    deploy:
      restart_policy:
        condition: any
  redis-db:
    image: redis
    volumes:
      - ./data/redis:/data
      - /etc/localtime:/etc/localtime:ro
    deploy:
      restart_policy:
        condition: any
  php-fpm:
    build: ./dockerfiles/php/
    restart: always
    environment:
      TP_APP_DEBUG: 'true'
    volumes:
#网站目录
      - ./app:/var/www/html:rw
#配置文件
      - ./dockerfiles/php/php.ini:/usr/local/etc/php/php.ini:ro
      - ./dockerfiles/php/php-fpm.conf:/usr/local/etc/php-fpm.conf:ro
#挂载站点日志
      - ./logs/php-fpm:/var/log/php-fpm:rw
    depends_on:
      - mysql-db
      - redis-db
    links:
      - mysql-db:mysql-db
      - redis-db:redis-db
    command: php-fpm

##附加扩展安装器
  composer:
    image: composer:1.4.2
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - ./app:/app:rw
    working_dir: /app/webroot
    deploy:
      restart_policy:
        condition: none
    command: composer install
  bower:
    image: digitallyseamless/nodejs-bower-grunt
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - ./app:/app:rw
    working_dir: /app/webroot
    deploy:
      restart_policy:
        condition: none
    command: bower install
