OKD 4.8 bootstrap 由于 DNS 而失败

Question

我正在尝试安装 OKD：

klenkes74@fortuna ~ $ ./openshift-install version
./openshift-install 4.8.0-0.okd-2021-10-10-030117
built from commit e0b12188a18a84be721116ddda74bb3510bfe03f
release image quay.io/openshift/okd@sha256:1d3f75529b141333939987ba03bf4ad76d83ae31d3b17df9a12c1f1ef67feff2

设置出现一些问题后（我在 hetzner.de 专用服务器上安装，这意味着我无法控制 DHCP、TFTboot、一般网络），系统正在启动。但是每个系统都以 'localhost' 出现。根据文档，使用了 DHCP 提供的名称（但 DHCP 似乎未在此处提供名称）。在这种情况下，应该从 IP 进行反向查找。根据 DNS，接口设置正确，但可能使用接口 'lo' 而不是 ehternet 卡 'enp8s'.

正在检查 DNS：

我是不是遗漏了一些配置？我的安装-config.yaml 非常基础：

---
apiVersion: v1
metadata:
  name: loki
baseDomain: kaiserpfalz-edv.de
compute:
- hyperthreading: Enabled
  name: worker

Answer 1

问题是Hetzner的特殊环境。我必须在节点启动后立即登录并重新配置主机名。下次重启后一切正常。
