# start container as *daemon*, mapping ports to local ports for external connections
docker run -d -p 9042:9042 -p 9160:9160 --name cassandra spotify/cassandra
- confirm cassandra is running:
# enter image
sudo docker exec -it cassandra /bin/bash
# connect via cqlsh

On local machine
- Install cassandra connector:
python3 -m pip install cassandra-driver
- Open python console, connect to server, and confirm session & query features:
>>> from cassandra.cluster import Cluster
>>>
>>> cluster = Cluster([IP_ADDRESS])
>>> session = cluster.connect()
>>>
>>> for keyspace in session.execute('SELECT * FROM system.schema_keyspaces'):
... print(keyspace)
...
Row(keyspace_name='system', durable_writes=True, strategy_class='org.apache.cassandra.locator.LocalStrategy', strategy_options='{}')
Row(keyspace_name='system_traces', durable_writes=True, strategy_class='org.apache.cassandra.locator.SimpleStrategy', strategy_options='{"replication_factor":"2"}')
>>> exit()
