EOF这个Dockerfile里我们主要做了以下几件事
- 设置容器用户为root
- 设置容器内的时区
- 将ssh私钥加入（使用git拉代码时要用到，配对的公钥应配置在gitlab中）
- 加入了登录自建harbor仓库的config文件
- 修改了ssh客户端的
- 安装一个docker的客户端

如上图所示，就是在下载插件的时候会出现Failure，建议更换为国内源

[root@mfyxw30 ~]# kubectl get pod -n infra -o wide
在mfyxw40.mfyxw.com主机上执行
[root@mfyxw40 ~]# docker ps -a | grep jenkins
在master节点(mfyxw30.mfyxw.com或mfyxw40.mfyxw.com)中任意一台操作即可
在jenkins容器中，验证jenkins容器是否以root身份运行及时区是否为东八区
[root@mfyxw30 ~]# kubectl exec -it jenkins-b99776c69-p6skp -n infra -- /bin/bash #进入到jenkins容器
root@jenkins-b99776c69-p6skp:/# whoami #查看jenkins是否以root身份运行
root@jenkins-b99776c69-p6skp:/# date #查看jenkins的时区是否为东八区
在jenkins容器中，验证是否连接宿主机的docker的引擎
[root@mfyxw30 ~]# kubectl exec -it jenkins-b99776c69-p6skp -n infra -- /bin/bash
root@jenkins-b99776c69-p6skp:/# docker ps -a
在mfyxw40.mfyxw.com宿主机上查询所有的容器运行情况，是否与进入到jenkins容器里查询到的一致
[root@mfyxw40 ~]# docker ps -a
在jenkins容器中，验证是否可以登录到harbor仓库
[root@mfyxw30 ~]# kubectl exec -it jenkins-b99776c69-p6skp -n infra -- /bin/bash
root@jenkins-b99776c69-p6skp:/# docker login harbor.od.com
root@jenkins-b99776c69-p6skp:/# cat /root/.docker/config.json
在jenkins容器中，验证是否可以登录到gitee仓库
[root@mfyxw30 ~]# kubectl exec -it jenkins-b99776c69-p6skp -n infra -- /bin/bash
