毕设_k8s集群拉起lnmp然后使用prometheus监控

Kubernets_LNMP

namespace为lnmp

表格

website1 和 website11内容应该同步

php镜像

vim 1

FROM php:7.0-fpm

 # 安装 MySQLi 扩展
 RUN docker-php-ext-install mysqli



 # 设置工作目录
 WORKDIR /var/www/html

 # 如果有其他依赖，可以在这里安装

 # 暴露 PHP-FPM 端口
 EXPOSE 9000

 # 启动 PHP-FPM
 CMD ["php-fpm"]

操作

docker build -t php7x -f 1 .

docker login --username=aliyun9875230798 registry.cn-hangzhou.aliyuncs.com

docker tag php7x registry.cn-hangzhou.aliyuncs.com/xiaolu77/work:php7x

docker push registry.cn-hangzhou.aliyuncs.com/xiaolu77/work:php7x

如果php的pod拉不起来 可能需要执行docker login这个命令.
