To install KairosDB, we need an instance of Apache Cassandra up and running. We can download Apache Cassandra from http://cassandra.apache.org. The Apache Cassandra team, however, has built an official Docker container. To run the container, enter the following command:

$ docker run -p 9042:9042 -p 9160:9160 --name cassandra0 cassandra

We can now install KairosDB, and we now have to develop and configure our plugin to ingest data from Apache Kafka to Apache Cassandra.
