环境：
centos7.9
jenkins/jenkins:lts-jdk11
1、拉去jenkins镜像，请指明版本号
[root@localhost ~]# docker pull jenkins/jenkins:lts开始拉取
拉取完成
[root@localhost ~]# docker pull jenkins/jenkins:lts

查看镜像，已经成功拉取

现在镜像拉取下来了，但是气门如果要启动对应的服务，需要创建一个容器，所有的操作全部在容器中进行，这个要是看不懂，可以自己搜索docker里面的知识点看看，这里不做详细阐述
在服务器上先创建一个jenkins工作目录 /var/jenkins_mount，赋予相应权限，稍后我们将jenkins容器目录挂载到这个目录上，这样我们就可以很方便地对容器内的配置文件进行修改
mkdir -p /var/jenkins_mount
chmod 777 /var/jenkins_mountmkdir /var/jenkins_home
chmod 777 /var/jenkins_home 当通过 docker run 命令启动 Jenkins 容器并使用 -v /var/jenkins_mount:/var/jenkins_home 参数时，这表示将宿主机上的 /var/jenkins_mount 目录挂载到容器内的 /var/jenkins_home 路径下
主机目录与容器内目录的关系
-
持久化存储：Jenkins 将所有配置文件、插件数据以及构建历史记录保存在
/var/jenkins_home下。因此，在宿主机上创建对应的挂载点可以确保即使删除容器后这些重要资料也不会丢失。
docker run --restart always -d -uroot -p 8080:8080 -p 50001:50000 -v /var/jenkins_mount:/var/jenkins_home -v /etc/localtime:/etc/localtime --name=jenkins002 jenkins/jenkins:latest这里我创建了一个jenkins001的容器，两个映射主机的端口分别为8080和50001，因为别的80、81 和50000我这里已经为别的容器服务期动画的时候制定了，为了防止端口被占用，
通过本队浏览器访问http://192.168.37.128:8080/
输入一下密码。
访问到了以后输入密码：
