docker方式 部署jenkins服务，实现持续集成（CI/CD）功能
一、背景：
因公司需求，需要部署一套jenkins自动化部署服务，并且是通过docker容器的方式部署的。
二、jenkins简介：
什么是Jenkins ？
Jenkins是一个开源软件，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（ CI/CD）。
三：CICD流程简介：
持续集成（ CI/CD）是什么？
CI（Continuous Integration）始终指持续集成 ，CD（Continuous Delivery/Continuous Deployment）是持续交付和/或持续部署，总结为如下三点。
- 持续集成
- 持续交付
- 持续部署
cicd基本流程：
四、docker部署jenkins服务：
1、拉取jenkins镜像：
docker search jenkinsci/blueocean
docker pull jenkinsci/blueocean
[root@iZwz9ippftvoxv000lpl0tZ ~]# docker search jenkinsci/blueocean

执行部署jenkins容器服务命令：
docker run -p 8080:8080 -p 8081:8081 -p 50000:50000 --name jenkins -v jenkins_data:/var/jenkins_home jenkinsci/blueocean
[root@iZwz9ippftvoxv000lpl0tZ ~]# docker run -p 8080:8080 -p 8081:8081 -p 50000:50000 --name jenkins -v jenkins_data:/var/jenkins_home jenkinsci/blueocean

3、登入jenkins服务：
这样利用你访问机器的IP地址+8080 即可出现jinkens的界面
会显示如下的内容
这里需要输入上面的获取到密码：436c75eef44d4db1a72f47da0300f659
4、初始化jenkins服务：
上面输入密码之后就会跳转到如下界面
注：这里选择推荐的插件
选择之后弹出如下：
创建一个管理员用户：
保存之后，需要重启一下jenkins服务。然后登入一下jenkins。
到此，jenkins服务的部署就完成了。
