Build

CoreDNS plugins need to be compiled into the main CoreDNS binary, with some minor changes to include the plugin.

• clone the main coredns repo
• clone coredns_omada repo
• both repos should share the same parent directory:

user@pc:/repos$ tree
.
├── coredns
└── coredns_omada

• in coredns/plugin.cfg add the following line to the START of the file: omada:github.com/dougbw/coredns_omada
• (optional for local development only): in coredns/go.mod add the following line to the END of the file. The following example assumes you have the coredns_omada repo located at /repos/coredns_omada so this needs to match your system.

replace github.com/dougbw/coredns_omada => /repos/coredns_omada

• run make from the coredns repo
• grab the coredns binary and add your Corefile configuration file
