• 因为要重装系统，所以镜像是windows系统里使用docker export命令导出的，然后重装完系统、装docker，用docker import导回去
• 环境说明：windows系统运行docker
• 提前说明：我这种情况以及解决方法不一定所有人都合适，仅供参考

D:\接口平台\interface>docker run -d -v D:\接口平台\interface:/var/www/interface -p 9000:9000 --name php tw-jiekou-php:v1
docker: Error response from daemon: No command specified.
See 'docker run --help'.

• 查看镜像信息，发现config里的cmd为null

docker inspect 999600f2d1e7（容器id）

		省略......

• 因此我们在运行容器的时候需要在命令后面加上/bin/bash
• 命令说明：因为用的phpstorm编辑器的命令行，所以windows环境下我也用/bin/bash(同linux)，如果是windows的cmd需要在开头加上winpty，结尾换成bash（没记错的话）

docker run -d -v D:\接口平台\interface:/var/www/interface -p 9000:9000 --name php tw-jiekou-php:v1 /bin/bash

• 用docker ps -a查看所有容器，发现php并没有启动，哪怕运行命令里加了-d

D:\接口平台\interface>docker ps -a

• 对比检查后发现COMMAND里少docker-php-entrypoint php-fpm导致php没有启动(ps:学的比较浅，并不知道这个的作用，如果有人知道可以留言教我一波哈)
