A simple dns server to read records from etcd. See this blog post for more information.
go get github.com/mrwilson/helixdns
go build -o hdns github.com/mrwilson/helixdns
hdns
-port=<port-to-run-on>
-etcd-address=<address-of-etcd-instance>
-forward=<address-of-forwarding-nameserver>
SRV records have multiple pieces of information to serve, so the values stored in etcd under /helix/com/example/_<protocol>/_<service>/SRV should be in the form of a list of JSON objects, as below.
[
{"Priority":10,"Weight":60,"Port":5060,"Target":"bigbox.example.com."},
{"Priority":10,"Weight":20,"Port":5060,"Target":"smallbox1.example.com."},
{"Priority":10,"Weight":10,"Port":5060,"Target":"smallbox2.example.com."},
{"Priority":10,"Weight":10,"Port":5066,"Target":"smallbox2.example.com."},
{"Priority":20,"Weight":0, "Port":5060,"Target":"backupbox.example.com."}
]
- Other types of record that aren't A, AAAA, CNAME, PTR, or SRV.
