ExternalDNS is an open-source application to make Kubernetes resources discoverable via public DNS servers.
We have deployed ExternalDNS on AWS in a large scale: externalDNS updates zones of more than 8000 resource records. During the external DNS development and deployment, we encountered challenges regarding AWS service limits, e.g. Route53 API frequency, Route53 resource record limit.
We will cover the following items in this talk:
- Overview of ExternalDNS in Cloud
- AWS Usage and Limit
- Challenges encountered to implement ExternalDNS in a large scale
- Implementation Enhancements and Solutions
