mDNS-publisher

This program allows you to register .local mDNS services from a configuration file controlling which IP they should be published under (as long as said IP is configured in one of your network interfaces.

Usage

You can place the configuration file in either:

/etc/mdns/config.hcl
/etc/mdns/config.yaml
/etc/mdns/config.json
/etc/mdns/config.toml

Or you can pass a path to the config:

./mdns-publisher --config /path/to/my/config_file.ext

Configuration

Here you can see a sample configuration in Hashicorp's HCL format. Alternatively, You can specify the configuration in YAML, JSON or TOML as long as it is equivalent.

bind_address = "192.168.2.21"
service {
    name = "Etcd"
    host_name = "etcd-0.local."
    type = "_etcd-server-ssl._tcp"
    domain = "local."
    port = 2380
    ttl = 300
}

You should always provide a bind_address, the address that will be propagated for the service. All the service fields are mandatory at the moment. Note that the mDNS library default ttl value is 3200.
