Docker Alpine镜像 安装php7

Alpine镜像安装php7后大小只有13M！！非常精简了！果断用上~
运行拉取alpine 镜像

docker run -dit --name php7.2-alpine -v D:\wwwroot:/var/www -p 8088:80 alpine:latest

进入容器

docker exec -it php7.2-min sh

安装nginx和php7服务

apk add nginx
apk add php7 php7-fpm php7-opcache php7-curl php7-gd php7-mbstring php7-mysqli php7-json

安装 rc-service

apk add openrc --no-cache

启动nginx

service nginx start
#或者rc-service nginx start

遇到以下错误问题

加入启动服务

/#  rc-update add nginx default
/#  rc-update add php-fpm7 start

保存镜像

/# commit php7.2-alpine liting68/php7.2-fpm-alpine

拉取运行新镜像

docker run -dit --name php7.2-alpine -v D:\wwwroot:/var/www -p 8088:80 liting68/php7.2-fpm-alpine /sbin/init

完成
