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