docker部署project-exam-system项目

8月30日笔记

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
