创建数据挂载目录，并赋予权限（保证服务挂掉以后，启动仍然能恢复数据）
```
mkdir -p /root/soft/jenkins/jenkins_home
chmod 777 /root/soft/jenkins/jenkins_home
```

创建实例

#docker run -d --name jenkins -p 8080:8080 -p 50000:50000 -v jenkins:/var/jenkins_home jenkins/jenkins:lts 
docker run -d --name jenkins -p 8080:8080 -p 50000:50000 -v /root/soft/jdk/jdk1.8.0_271:/usr/local/jdk/jdk1.8.0_271 -v /root/soft/maven/apache-maven-3.6.3:/usr/local/maven -v /root/soft/jenkins/conf:/conf/ -v /root/soft/jenkins/jenkins_home:/var/jenkins_home jenkins/jenkins:lts
                    
# -v /root/soft/jdk/jdk1.8.0_271:/usr/local/jdk/jdk1.8.0_271 挂载宿主机的JDK
# -v /root/soft/maven/apache-maven-3.6.3:/usr/local/maven 在全局系统变量可以配置maven路径/usr/local/maven
