终于搞定php7-alpine的docker镜像-PHP7-PHP中文网

我花了大概一周的时间进行了各种踩坑及实验，最终得出了一份可以使用的dockerfile及compose

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

# 安装composer依赖
#RUN composer install

# php-fpm使用以下配置
EXPOSE 9000

# swoole 使用以下配置
EXPOSE 9501
# 启动swoole server

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

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
