Apache Kafka with Reactive Messaging: Workshop is incomplete and consequently doesnt work

Apache Kafka with Reactive Messaging

At what step of the scenario did this happen?

Step 4

Describe the bug

When starting this workshop I was already a bit surprised that it went straight into working with Quarkus. I thought that Kafka might already be set up and ready, but it turns out this is not the case. When it comes to the last step of actually deploying the Quarkus app on OpenShift, the container crashes because it cannot find Kafka.

I launched my own cluster and tried to reproduce the "Apache Kafka basics" Katacoda workshop steps on there (to setup Kafka) and then I reproduced the steps for this "Apache Kafka with Reactive Messaging" workshop, and it works! This means, that this workshop is just missing the initial steps on creating Kafka as described in the other workshop.
