在docker的官方php镜像中，有独立的php和apache版本的，这里尝试用php-fpm7.2.1（alpine3.7）作为基础镜像，在把nginx1.13.8加进去.
第一步:拉取php镜像：
docker pull php:7.2.1-fpm-alpine3.7
第二步：创建镜像制作工作目录(根据自己喜好来创建)：
mkdir ~/dockerfiles
cd ~/dockerfiles
mkdir nginx-phpfpm
cd nginx-phpfpm
第三步：创建编辑Dockerfile
vi Dockerfile
FROM php:7.2.1-fpm-alpine3.7

第四步，开始编译
修改nginx.conf 使之支持php.然后：
docker build -t ikodota/nginx-phpfpm-alpine:7.2.1 .
