WARNING: IPv4 forwarding is disabled. Networking will not work
解决办法：https://www.jianshu.com/p/82067b8c0190
/etc/sysctl.conf增加net.ipv4.ip_forward=1（暂不处理，影响systemctl）

systemctl restart network && systemctl restart docker 重启

设置向导
http://localhost:8080 解锁 Jenkins
1 从Jenkins控制台日志输出中，复制自动生成的字母数字密码（在两组星号之间）
/var/jenkins_home/secrets/initialAdminPassword
find / -name initialAdminPassword
2 在 Customize Jenkins 页面内, 您可以安装任何数量的有用插件作为您初始步骤的一部分
3 创建第一个管理员用户
可能显示 Jenkins几乎准备好了! 相反，如果是这样，请单击 重启

你已跳过创建admin用户的步骤。要登录请使用用户名：‘admin’ 及用于访问安装向导的管理员密码
