记录我网站的Dockerfile

本站（以前使用vps时）运行基于docker容器，在此记录Dockerfile镜像构建文件的相关内容，基础镜像使用alpine3.8

导入的时候一般指明版本, 不推荐使用latest

FROM alpine:3.8

修改镜像源地址为阿里云，并更新

RUN sed -i \'s~dl-cdn.alpinelinux.org~mirrors.aliyun.com~\' /etc/apk/repositories \\
	&& apk update \\

安装软件,这里安装的是tzdata，php与相关扩展，nginx

    && apk add --no-cache tzdata php7 php7-fpm php7-ftp php7-pdo php7-mysqli php7-simplexml php7-xmlwriter php7-zlib php7-imagick php7-memcached php7-sockets php7-mcrypt php7-zip php7-pgsql php7-pdo_odbc php7-odbc php7-curl php7-iconv php7-xml php7-json php7-gd php7-session php7-opcache php7-pdo_sqlite php7-mbstring php7-oauth php7-common php7-pdo_mysql nginx \\

设置默认时区

    && cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime \\
    && echo \"Asia/Shanghai\" > /etc/timezone \\

为nginx运行新建/run/nginx

	&& mkdir /run/nginx \\

清理运行时不需要的软件和安装缓存

    && apk del tzdata \\
    && rm -rf /var/cache/apk/* \\
    && rm -rf /root/.cache \\
    && rm -rf /tmp/*

指明工作目录

WORKDIR /

指定容器启动脚本（自己摸索的方法，让php、nginx在容器启动时自启动）

CMD php-fpm7 && nginx && sh && exit

完整Dockerfile
