   cp -r /certs/ /tmp/
   cd /tmp/ && chmod -R  0700 certs/
   cd  /cockroach
   ./cockroach sql --certs-dir=/tmp/certs/ --host=zen-metastoredb-0.zen-metastoredb
   use zen;
   drop table policies;
   drop table products;
   drop table monitors;
   drop table monitor_events;
   drop table event_types;
