为什么用docker，想象一下你换了电脑或者服务器，或者新人接触你的项目，一个docker打包新电脑丢上去，还跟原版环境相同，它不快乐？，所谓工欲善其事必先利其器。
如果从安装Docker Desktop学起，请先读本文下面学习docker彩踩过的坑
创建目录docker，其下目录结构
运行docker-composer up -d，等待执行成功后，本地访问127.0.0.1访问www根目录
访问，需在在本地host文件添加，127.0.0.1

在学习docker过程中踩过的坑：
windows环境下，下载的Docker Desktop 会发现无法运行，解决办法分别为，开启虚拟化（请自行百度），下载低版本的docker，我这里的docker版本为2.3.0.2挂载问题， 挂载失败，去setting里添加挂载盘，截图如下 单纯的拉取PHP官方镜像，运行后无法连接数据库，各种扩展没有，在docker的PHP容器内是无法找到php.ini文件的，安装扩展和开启扩展是单独有docker-php-ext-install等一系列docker-php-ext命令有，请自行百度docker安装PHP扩展
