Java 如何在centos v8上更改jenkins主目录位置？

我通过命令在docker上安装了jenkins

docker run-p8080:8080-p50000:50000-d-v jenkins_home:/var/lib/docker/volumes/jenkins_home/_datajenkins/jenkins:lts

我指定了jenkins\u home:/var/lib/docker/volumes/jenkins\u home/\u数据

但我不明白为什么会显示这样的jenkins：Home directory/var/jenkins\u Home

奇怪的是这个目录（/var/jenkins_home）是空的：

/var/jenkins#u home#ll总计0

这导致docker构建步骤出现问题

日志：

作为系统运行
在工作区内构建/var/jenkins_home/workspace/jenkins-docker集成
推荐的git工具是：无
使用凭证git
>git rev parse——解析git dir/var/jenkins_home/workspace/jenkins docker integration/.git#timeout=10
从远程Git存储库获取更改
>git config remote.origin.urlhttps://github.com/************.git#超时=10
从中获取上游更改https://github.com/*************吉特先生
>git——版本#超时=10
>git--版本#“git版本2.20.1”
使用GIT_ASKPASS在GIT中设置凭据
