Appendix

Run This Demo Yourself (no Gitpod)

Choosing your Docker host environment

  • This demo (currently) runs 16 different Docker containers, so this might be too much for your laptop.
  • Testing has been done on a c4.4xlarge EC2 instance, with good performance (probably over-provisioned).
  • It's recommended to run docker system prune -a before running docker-compose

Configuring the demo environment

  • Running a really big pcap [optional]

    • The packet capture file included in this repository features DNS exfiltration (among other things), but will repeat itself after a few minutes. This can be tiresome during a live demo or workshop.
    • Run python3 scripts/get_pcap.py script to download a 1GB/1hr playback pcap.

  • Configure Control Center's ksqlDB advertised listener

    • You need to advertise the correct hostname for the ksqlDB server to ensure that the ksqlDB editor in Confluent Control Center can communicate with the ksqlDB server.
    • In the docker-compose.yml file, change the value of CONTROL_CENTER_KSQL_KSQLDB1_ADVERTISED_URL to http://localhost:8088 if running locally, or to whatever the public DNS hostname is for your EC2 instance.

Starting the demo

  • Run docker-compose up -d

If you are using sudo with docker-compose then you will likely need to use the -E option to sudo so it inherits your environmental variables so the last command will become sudo -E docker-compose up -d
