ZookDNSAgent registers a service into Zookeeper by creating DNS records as epemeral znodes. These records will be queried by clients through ZookDNS.
Simply set the following env variables and run the agent on your service.
// Used to create SRV records. See [RFC-6763]
"ZOOKDNS_SERVICE_INSTANCE"
"ZOOKDNS_SERVICE_NAME"
"ZOOKDNS_SERVICE_DOMAIN"
"ZOOKDNS_SERVICE_WEIGHT"
"ZOOKDNS_SERVICE_PRIORITY"
"ZOOKDNS_SERVICE_PORT"
// Host name and address of service
"ZOOKDNS_SERVICE_HOST"
"ZOOKDNS_SERVICE_HOST_ADDRESS"
ZookDNSAgent will create an PTR, SRV and A record with this information.
Additionaly override the default Zookeeper address by setting the ZOOKDNS_ZOOKEEPER_ADDRESS variable.
In the case of a disconnect ZookDNSAgent will periodically attempt to reconnect to ZooKeeper.
