外部 DNS 跳过记录（未检测到匹配的托管区域）

Question

我在我的集群上创建了外部 DNS（由 DigitalOcean 提供），并为 stable/external-dns Helm 图表设置了以下值：

provider: digitalocean
digitalocean:
  apiToken: "MY_DIGITAL_OCEAN_TOKEN"
domainFilters:
  - example.com
rbac:
  create: true
logLevel: debug

以前还好，最近由于no hosted zone matching record DNS Name was detected:

停止了创建记录

time="2019-06-10T14:42:55Z" level=debug msg="Endpoints generated from ingress: deepfork/df-stats-site: [fork.example.com 0 IN A 134.***.***.197 [] fork.example.com 0 IN A 134.***.***.197 []]"
time="2019-06-10T14:42:55Z" level=debug msg="Removing duplicate endpoint fork.example.com 0 IN A 134.***.***.197 []"
time="2019-06-10T14:42:56Z" level=debug msg="Skipping record fork.example.com because no hosted zone matching record DNS Name was detected "
time="2019-06-10T14:42:56Z" level=debug msg="Skipping record fork.example.com because no hosted zone matching record DNS Name was detected "

Answer 1

此错误消息来自kubernetes-incubator/external-dns provider/digital_ocean.go#digitalOceanChangesByZone(), a project for which you have opened an issue (1064)

检查这是否与 issue 1055 无关，后者在使用带有 "latest" 标签的图像时也有类似的问题。

最近的提交可能会解决这个问题：

commit dc5099d which refers to issue 1056，其中提到了"Having traced this the issue appears to be that the exclude-domains has a default value of "". that leads to always matching the exclude"
commit 6f543ec which solves issue 1057: "Google DNS zones not found with filter"

Answer 2

当我用 DigitalOcean web interface 手动添加记录时，问题得到了解决。在那之后，ExternalDNS 开始忽略添加新记录，因为它已经存在了。

time="2019-06-18T11:09:55Z" level=debug msg="Removing duplicate endpoint fork.example.com 0 IN A 134.***.***.197 []"

后来我用接口去掉了记录，ExternalDNS就开始工作了。

time="2019-06-18T11:10:56Z" level=info msg="Changing record." action=CREATE record=fork.example.com ttl=300 type=A zone=example.com
time="2019-06-18T11:10:56Z" level=info msg="Changing record." action=CREATE record=fork.example.com ttl=300 type=TXT zone=example.com

外部 DNS 跳过记录（未检测到匹配的托管区域）

External DNS skips records (No matching hosted zone was detected)
