用Dockerfile生成docker image

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

LABEL maintainer="NGINX-PHPFPM Docker Maintainers <ikodota@gmail.com>"

ENV NGINX_VERSION 1.13.8

EXPOSE 443 80

STOPSIGNAL SIGTERM

CMD ["nginx", "-g", "daemon off;"]

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 .
