我的系统具有通过自定义内部域名与 LAN 上的其他服务器通信的服务。我的 netplan 设置如下：
network:
ethernets:
ens160:
addresses:
- 192.168.12.10/24
gateway4: 192.168.12.1
nameservers:
addresses: [192.168.12.1, 8.8.8.8, 8.8.4.4]
optional: true
version: 2
当服务器在重启后启动时，似乎 192.168.12.1 被忽略为名称服务器，因为尝试curl -v
或 ajax 到本地服务时的响应不是来自我的本地 dns 服务器。但如果我运行，netplan --debug apply我的输出是正常的，一切都会再次正常工作，直到我重新启动系统。
cron除了设置运行作业之外，还知道如何修复此问题@reboot /usr/sbin/netplan apply吗？
系统：
Operating System: Ubuntu 18.04.4 LTS
Kernel: Linux 4.15.0-99-generic
netplannetplan在启动时分配正确的静态 IP，但不使用名称服务器。系统外部没有任何其他自定义网络配置/静态路由ufw。ufw允许 22 和 nginx 已满。

netplan 对缩进、间距和制表符非常挑剔。
