kops 更新集群失败，“为 NS 记录执行 DNS 查找时出错”，“没有这样的主机”

Question

环境

$ kops version
Version 1.18.2 (git-84495481e4)

Kubernetes Cluster Version: 1.18.10

我想做什么

我想在我的域中创建一个 Kubernetes 集群 xway.me。

我找到 this article 并尝试了。

我创建了一个集群并尝试打印 terraform 文件作为输出但它失败了。

$ kops update cluster \
  --out=. \
  --target=terraform \
  --state s3://xway.me-kops \
  --name xway.me

error doing DNS lookup for NS records for "xway.me": lookup xway.me on 127.0.0.53:53: no such host

我试过的

Error doing DNS lookup for NS records when using a Private DNS zone #781

我加了--dns private

但是我得到了unknown flag: --dns。

Installing Kubernetes on AWS with kops

现在我的resolv.conf来了

# This file is managed by man:systemd-resolved(8). Do not edit.
#
# This is a dynamic resolv.conf file for connecting local clients to the
# internal DNS stub resolver of systemd-resolved. This file lists all
# configured search domains.
#
# Run "systemd-resolve --status" to see details about the uplink DNS servers
# currently in use.
#
# Third party programs must not access this file directly, but only through the
# symlink at /etc/resolv.conf. To manage man:resolv.conf(5) in a different way,
# replace this symlink by a static file or a different symlink.
#
# See man:systemd-resolved.service(8) for details about the supported modes of
# operation for /etc/resolv.conf.

nameserver 127.0.0.53
options edns0
search ad.oit.ac.jp

我在 /etc/resolv.conf.

添加这段代码

search xway.me

然后我得到这个错误。

error doing DNS lookup for NS records for "xway.me": lookup xway.me on 127.0.0.53:53: server misbehaving

添加nameserver 8.8.8.8也失败了

error doing DNS lookup for NS records for "xway.me": lookup xway.me on 127.0.0.53:53: no such host

使用 kops 创建：

$ kops create cluster --name xway.me --state s3://xway.me-kops

cluster "xway.me" already exists; use 'kops update cluster' to apply changes

我想知道

如何才能成功运行 kops update cluster?

Answer 1

当您使用私有 DNS 记录时，它们通常不会在本地解析。您需要一个托管在 VPC 中的 DNS 转发器，该 VPC 启用了私有 route53 记录。

kOps 记录不会暴露任何特别敏感的内容，但如果您不想使用 public 记录，可以选择使用 Gossip cluster.

不过有一个known issue with combining gossip with terraform。
