# **基于Docker安装Jenkins环境** #

1.使用docker 安装jenkins

<table style="width:414.8pt;"> 
 <tbody> 
 <tr> 
 <td style="vertical-align:top;width:414.8pt;"> docker run -p 8080:8080&nbsp;&nbsp;-p 50000:50000 -v jenkins_data:/var/jenkins_home&nbsp;--name jenkins -idt &nbsp;jenkinsci/blueocean </td> 
 </tr> 
 </tbody> 
</table>

查找目录命令

find / -name jenkins\_data -depth

2.访问jenkins地址 8080

注意：第一次启动的时候正在加载jenkins大概会等待3-10分钟。

3.解锁jenkins

docker exec -it 7f485bd95c3b  /bin/bash 进入jenkins容器

cat /var/jenkins\_home/secrets/initialAdminPassword

大概需要等待3-10分钟

创建新的用户

## **Jenkins全局工具配置** ##

进入到jenkins容器中 echo $JAVA\_HOME 获取java环境安装地址

### **JDK环境安装** ###

**Maven环境安装**

### **安装Jenkins对应Maven插件** ###

找到 “系统管理“ - “安装插件” ，点击 “可选插件”，找到如下maven插件的版本

插件名称 [Maven Integration][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM5OTQwMjA1_size_16_color_FFFFFF_t_70 7][]

## **Jenkins实现Springboot项目自动部署** ##

1.  新建一个发布任务![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM5OTQwMjA1_size_16_color_FFFFFF_t_70 9][]

1.   配置任务git账号密码

3.项目打包

clean install  -Dmaven.test.skip=true

1.  点击立即构建

第一次构建可能耗时比较长，因为需要下载一些相关依赖jar包

## **    Jenkins启动成功之后执行shll脚本** ##

**Jenkins****启动S****pringBoot后，****停止****转圈**

**将springboot****启动方式设置为后台启动即可**

# **部署的项目映射8090端口(项目8090,jenkins8080)** #

1.  重启容器

systemctl restart  docker

1.  删除旧的jenkins容器

docker rm jenkins容器id

重新运行

<table style="width:414.8pt;"> 
 <tbody> 
 <tr> 
 <td style="vertical-align:top;width:414.8pt;"> docker run -p 8080:8080&nbsp;-p 8090:8090 -p 50000:50000 -v jenkins_data:/var/jenkins_home&nbsp;--name jenkins -idt &nbsp;jenkinsci/blueocean </td>
