Ubuntu 18 私有云环境下 hosts 解析问题

[wnxn]

What happened: 私有云环境下解析 api.ks.qingcloud.com 失败

What you expected to happen: 能够成功解析

How to reproduce it (as minimally and precisely as possible):

Anything else we need to know?: qke 1.0.0 使用 ubuntu16 无此问题 qke 1.0.1 使用 ubuntu18 有此问题 疑与 ubuntu 18 使用 systemd-resolve 有关。18开始systemd-resolve会让dns指向127.0.0.53环回，它再接管。

systemd-resolve --statistics 看 dns 状态

Environment:

• QKE version: v1.0.1
• Cloud resource ID (e.g. region, zone, clusterid, instance id, volume id):
• Others:
