A simple service mDns based service discovery tool written in golang.

The goal was to create a small binary that I can set up as a service on boxes deployed in my home network, so I can keep track of them if their IP's change.

Usage:

The service requries a configuration file. An example configuration can be found in config.yaml. ./main -config config.yaml

How to build:

go build main.go

How does it work?

There are two modes, discovery and service:

• Service mode: runs on the box that you want to keep track of.

  • This uses mDns to make the service discoverable.
  • It has the ability to share it's: node name, the type service it hosts, the protocol that service uses, the port for the service, and any metadata you want to configure.

• Discovery mode: will find the services on the network placed in service mode.

  • Requires you to know the type of service it's looking for a protocol, and it's domain.
