While switching to use ssl for a communication with Cassandra, sdc-cs-init container fails. It happens because this container contains old cqlsh client which doesn't know "–ssl" flag. It would be needed to update cqlsh client version from 4.0.1 to at least 5.0.1 in base_sdc-cqlsh.

Docker files are located here: https://gerrit.onap.org/r/#/admin/projects/sdc/sdc-docker-base and required change would have to be done in sdc-docker-base/ base_sdc-cqlsh.
