trying to deploy cassandra on kubernetes using bitnami image

Hi team, 

Trying to deploy cassandra on the kubernetes cluster, pod getting up but suddenly going in to the error state. I am adding the error that I am getting in the logs.

INFO [main] 2021-02-24 12:46:56,408 DatabaseDescriptor.java:775 - Back-pressure is disabled with strategy org.apache.cassandra.net.RateBasedBackPressure{high_ratio=0.9, factor=5, flow=FAST}.

ERROR [main] 2021-02-24 12:46:56,455 CassandraDaemon.java:803 - Exception encountered during startup: The seed provider lists no seeds.

 Please help as this is stuck.
