   @michaelsembwever I tested removing the `-e CQLVERSION` and `--cqlversion` 
flags locally as suggested, but unfortunately, it causes the connection to fail.
   
   It seems the `nuvo/docker-cqlsh` image defaults to an older CQL version 
(`3.3.1`) when no version is specified, which is incompatible with the latest 
Cassandra image.
   
   **Verification without flags:**
   
   `docker run --rm -it --network cassandra nuvo/docker-cqlsh cqlsh cassandra 
9042`
   
   **Result:**
   `Connection error: ('Unable to connect to any servers', {'172.19.0.2': 
ProtocolError("cql_version '3.3.1' is not supported by remote (w/ native 
protocol). Supported versions: [u'3.4.7']",)})`
   
   So, explicitly specifying `3.4.7` seems necessary for this specific Docker 
image to work with the latest Cassandra.
