Thanks @h0x0er!

Few changes are needed:

1. Use the constants for the file names that are defined in dnsconfig.go2.
   

   agent/dnsconfig.go

   Line 21 in ca30228

   dockerDaemonConfigPath = "/etc/docker/daemon.json"

2. You need to also detect if the files changed. If they did, add an annotation. See the below code for where this needs to be done.
   

   agent/eventhandler.go

   Line 44 in ca30228

   if strings.Contains(event.FileName, "post_event.json") {
