部署方式

参考 kubernetes-sigs/external-dns/docs/tutorials/ 页面，该目录提供针对多个 DNS Provider 进行配置的案例。

with Manifest / on Tencent Cloud

腾讯云 / 在 TKE 中，配置 ExternalDNS | https://cloud.tencent.com/document/product/457/72679

kubectl create namespace external-dns
kubectl config set-context --current --namespace external-dns

kubectl apply -f dnspod.yaml

Q：… failed to sync v1.Ingress: context deadline execeded …
A：通过 YAML 部署，需要注意 ClusterRoleBinding.subjects[].namespace 配置，错误配置将导致其无法访问 api-server 而退出。
R：failed to sync v1.Ingress: context deadline exceeded · Issue #2407 · kubernetes-sigs/external-dns

with Manifest / on AWS

https://github.com/kubernetes-sigs/external-dns/blob/master/docs/tutorials/aws.md
