This is the example Dockerfile taken from here
Clone the project and build the DSE Docker Image docker build -t dse/docker .
You can deploy a cluster of nodes by runnning the cluster-launcher.sh script ./cluster-launcher.sh dse/docker [num_nodes]
You can also specify node type after num_nodes, for example ./cluster-launcher.sh dse/docker 3 -k. This would bring up a 3 node DSE Cassandra cluster in Spark Analytics mode.
Connect to a running node with docker exec -it node1 bash
