Prepare Kafka for IoT with DCOS

In the blog post Install dev environment for Kafka, Nodejs and node-red I described to install a kafka – webstorm environment on a virtual machine. For a productive use, we need high availability kafka installation. The idea is to use an orchestration framework like DCOS. It is based on the documentation of mesosphere https://docs.mesosphere.com/1.8/usage/tutorials/iot_pipeline/.
