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

2、部署jenkins服务：

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
