执行基础镜像
root@master:/opt/k8s-data/dockerfile/linux37/jenkins# bash build-command.sh 
后台运行
root@master:/opt/k8s-data/dockerfile/linux37/jenkins# docker run -it -d -p 8901:8080 harbor.wyh.net/linux37/jenkins:v2.190.1 
进入到容器里

把/root/.jenkins/放在后段存储上
[root@69d50f8ab2d1 ~]# ls /apps/jenkins/jenkins-data/
这个jenkins数据放在后段存储上
请从本地复制密码并粘贴到下面。
[root@a4289d376b5e yum.repos.d]# cat /root/.jenkins/secrets/initialAdminPassword
