一、jenkins介绍
Jenkins是一个开源软件项目，是基于Java开发的一种持续集成工具，用于监控持续重复的工作，旨在提供一个开放易用的软件平台，使软件项目可以进行持续集成。
二、jenkins功能
- 一个自动构建过程，包括自动编译、分发、部署和测试等。
- 一个代码存储库，即需要版本控制软件来保障代码的可维护性，同时作为构建过程的素材库。
- 一个持续集成服务器。
三、检查本地docker状态
[root@node ~]# systemctl status docker

Status: Downloaded newer image for jenkins/jenkins:latest
docker.io/jenkins/jenkins:latest
五、部署jenkins
1.创建数据目录
[root@node ~]# mkdir -p /data/jenkins/data
[root@node ~]# chmod -R 777 /data/jenkins/data/
[root@node ~]#
2.创建jenkins容器
[root@node jenkins]# docker run -d --name jenkins --restart always -p 8774:8080 -p 50100:50000 -v /data/jenkins/data/:/var/jenkins_home -v /etc/localtime:/etc/localtime jenkins/jenkins
b44ef8c88d09e5eebb996c91691101fb534859aa3185bdc8bf3c0a8ebf443cbf
3.查看jenkins容器状态
[root@node jenkins]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
b44ef8c88d09 jenkins/jenkins "/sbin/tini -- /usr/…" 2 minutes ago Up 2 minutes 0.0.0.0:8774->8080/tcp, :::8774->8080/tcp, 0.0.0.0:50100->50000/tcp, :::50100->50000/tcp jenkins
六、配置jenkins镜像加速
[root@node data]# cat hudson.model.UpdateCenter.xml
<?xml version='1.1' encoding='UTF-8'?>
<sites>
<site>
<id>default</id>
<url>https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json</url>
</site>
</sites>
七、访问jenkins
[root@node data]# cat secrets/initialAdminPassword
9e501f00a41f472292367def3724d81b
[root@node data]#
八、jenkins初始化及安装插件
九、创建管理员账号
十、进入jenkins首页
