If you are exposing the port and want to access it via the host IP of the system running docker, you should configure the broadcast_rpc_address in cassandra.yaml to be that of your ubuntu server (10.7.108.10).

If you are using the official cassandra image you can pass in -e CASSANDRA_BROADCAST_ADDRESS=10.7.108.10 as documented.

Additionally, I see that you are exposing port 9043. Are you explicitly configuring the binary port in that way? It defaults to 9042.
