Documented at https://simbo1905.wordpress.com/2017/02/24/cassandra-for-shared-media-libraries/

start three nodes

docker run -d --name "cass0" zmarcantel/cassandra
docker run -d --name cass1 --link cass0:cass0 zmarcantel/cassandra
docker run -d --name cass2 --link cass0:cass0 --link cass1:cass1 zmarcantel/cassandra

capture the image names and extract their IPs

export CASSDOCK_ID=`docker ps | grep cassandra | awk '{print $1}' | xargs`
docker inspect $CASSDOCK_ID | grep IPAddress | sed 's/"IPAddress": "/ /g' | sed 's/",//g' | sed 's/ //g' | grep -v null | sort -u

open bash as root on one node and install then run the python cassandra query tool

docker exec -it `docker ps | grep cassandra | awk '{print $1}' | head -1` bash
