k8s部署微服务springcloud从0-1(微服务环境搭建和项目创建)

一.数据库服务准备

1.1 mysql准备

 #安装mysql
 docker run -itd --name mysql-test -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 mysql
 #创建数据库和表
 create database docker;
create table `tb_article`(
    `id` INT UNSIGNED AUTO_INCREMENT,
    `title` VARCHAR(100) NOT NULL,
    `content` MEDIUMTEXT,
    `author` varchar(100) NOT NULL,
    `addtime` DATETIME,
  PRIMARY KEY ( `id` )
)ENGINE=InnoDB DEFAULT CHARSET=utf8;

1.2 redis准备

docker run -di  --name=redis -p 6379:6379 redis

二.微服务搭建
