Unable to define contact points with container names for scyllaDB (using phantom library in scala)

Question

I'm trying to use scyllaDB container names instead of IP while setting contact points in scala (using phantom library). Contact Points with IP is working fine:

new BooksDatabase(ContactPoints(List("172.30.0.3", "172.30.0.2", "172.30.0.4"))
      .keySpace("books_keyspace"))

But Contact Points with container names not working:

ContactPoints(List("scyllaDB-node1", "scyllaDB-node2", "scyllaDB-node3"))
      .keySpace("books_keyspace"))

Error/Exception:

Failed to add contact point: scylla-node1
java.lang.IllegalArgumentException: Failed to add contact point: scylla-node1

Caused by: java.net.UnknownHostException: scylla-node1: Temporary failure in name resolution

Here is scyllaDB cluster with 3 nodes:

Help me, how can I use container names to make contact points. Any help is appreciated.
