前言
Caddy 是一款用golang编写的轻量级web server
老早就看到caddy web server,但是找不到去用的理由,因为nginx足够好
如果用docker打包应用,如果要实现跑php php-fpm应用且要单容器,用nginx就不太爽了
一般用php官方docker镜像作为base,然后在上面再装nginx,nginx复杂的编译环境非常麻烦
试用了下 caddy,他就没那么麻烦,还是用php官方docker镜像,然后只需要简单的几行就可以把caddy加进去
非常特别的一点是caddy自带php-fpm的进程启动
在配置文件中增加on startup php-fpm —nodaemonize 即可
容器的入口只需要启动caddy即可,caddy可以自动启动php-fpm进程
目前发现唯一的问题是caddy对个人免费,对公司和商业收费,价格还非常贵
下面是一些参考文件

其他
在dockerfile中，是直接下载的caddy二进制程序，这个会受到caddy的授权协议影响，对个人免费，对商业收费
如果是基于源码自己编译安装那么就只需要遵守Apache license协议即可，即可以用于商业
