项目实战：使用docker部署project-exam-system
1、背景：
使用基础的docker指令来创建镜像，实现项目的发布，使用Dockderfile，docker compose编排容器。
2、环境准备：
（1）主机 dokcer01(192.168.2.80)
（2）部署docker环境，执行脚本，参照之前的文章
[root@dokcer01 ~]# vim /etc/docker/daemon.json
{
"registry-mirrors": [
"https://do.nark.eu.org",
"https://dc.j8.work",
"https://docker.m.daocloud.io",
"https://dockerproxy.com",
"https://docker.mirrors.ustc.edu.cn",
"https://docker.nju.edu.cn"
]
}
[root@dokcer01 ~]#systemctl restart docker
3、普通部署
#####前端:nginx latest服务######
# 拉取nginx镜像
[root@dokcer01 ~]#docker pull nginx
[root@dokcer01 ~]# docker images

# 测试成功，但出现问题，实现登录的时候出现后端异常，因为还没部署后端
# 设置域名劫持，在真机的hosts文件中添加域名来实现登录的时候请求的域名ks.tangpin.huajuan
#####后端:jdk17 springboot(不单独部署tomcat,已经在springboot中内置tomcat)######
# 拉取基础centos镜像
