extends org.apache.ignite.spi.discovery.tcp.ipfinder.vm.TcpDiscoveryVmIpFinder

Apache Ignite usage on Kubernetes requires that each node (Pod in the Kubernetes lingo) is able to access other pods directly. Proxies will not work.

In order to find the desired pods IP addresses, one could query the Kubernetes API for endpoints of a Service but that may prove too much of a hurdle to maintain. Since DNS integration is a common best-practice when assembling Kubernetes clusters, we will rely on SRV lookups.
