Overview

Package corednsplugin is an adaptor which converts gslbcore.Core to a CoreDNS plugin.

By using the adaptor, we can focus on the GSLB logic in gslbcore.Core, and split the DNS protocol details.

Overview:

• `setup.go` is primarily about how to handle the custom directives in the configuration file and configure `gslbcore.Config` accordingly.
• `handler.go` provides the CoreDNS plugin implementation. It focuses on how to handle DNS requests and generate corresponding responses.
