如何构建一个php7-alpine的docker镜像

这篇文章主要介绍"如何构建一个php7-alpine的docker镜像"，在日常操作中，相信很多人在如何构建一个php7-alpine的docker镜像问题上存在疑惑，小编查阅了各式资料，整理出简单好用的操作方法，希望对大家解答"如何构建一个php7-alpine的docker镜像"的疑惑有所帮助！接下来，请跟着小编一起来学习吧！

内含如下支持

• php7

• mysql_pdo

• postgre_pdo

• phpredis

• swoole(可选，如应用swoole，dockerfile及nginx的配置会有所变化)

dockerfile分为两部分，一部分为php服务，一部分为nginx(swoole下可选)

先贴代码吧

### php7 ###

## swoole可以不依赖nginx 所以我单独贴出php-fpm的nginx

nginx-dockerfile:

from nginx:1.13.6-alpineENV TIME_ZONE Asiz/ShanghaiRUN sed -i 's/dl-cdn.alpinelinux.org/mirrors.ustc.edu.cn/g' /etc/apk/repositories && \    apk update && \    apk add --no-cache tzdata  && \    echo "${TIME_ZONE}" > /etc/timezone && \    ln -sf /usr/share/zoneinfo/${TIME_ZONE} /etc/localtime COPY default.conf /etc/nginx/conf.dEXPOSE 80STOPSIGNAL SIGTERMCMD ["nginx", "-g", "daemon off;"]

nginx_php-fpm:default.conf:

server {    listen       80;    server_name  *.yourserver.com;    location / {          autoindex on;           if ($request_filename !~* /(index\.php|assets|uploads|phpinfo\.php))             {                  rewrite ^/(.*)$ /index.php/$1 last;                                                                                                             }                                                                                          }    location ~ .php(/|$) {        fastcgi_split_path_info ^(.+?\.php)(/.*)$;        fastcgi_pass php-fpm:9000;        fastcgi_index index.php;        fastcgi_param SCRIPT_FILENAME /www$fastcgi_script_name;        fastcgi_param PATH_INFO $fastcgi_path_info;        include fastcgi_params;    } }

compose:

* swoole的编排模板很容易写 我就不在这里贴出了

version: '2'services:  php-fpm:    image: "php-fpm"    restart: always    #日志系统，可不写    #logging:    #  driver: fluentd    #  options:    #    fluentd-address: "logaddr:24224"    #    tag: "docker/{{.Name}}/{{.ID}}/{{.ImageName}}"  php-nginx:    image: "php-nginx"    depends_on:    #这几个\是转义字符 但是不知道为什么就显示出来了，使用的时候自己去掉一下      \- php-fpm    ports:      \- "80:80"    links:      \- php-fpm    restart: always    #日志系统，可不写    #logging:    #  driver: fluentd    #  options:    #    fluentd-address: "logaddr:24224"    #    tag: "docker/{{.Name}}/{{.ID}}/{{.ImageName}}"

我所做的是对php及nginx进行解耦
如果集群内有多个php服务需要互相访问，
因为compose不允许两个服务互相link
所以需要创建一个network在network中借助nginx进行互相访问
但是目前只有v3版的compose支持本功能，很多旧集群都无法正常支持本功能，所以我就不贴出代码了
编辑完成后，即可通过80端口访问index.php了
