Default, simple, and ephemeral Kafka cluster using AMQ Streams (Strimzi). Feel free to change the name my-cluster and/or the labels app: my-app, and of course anything else in there.

Before applying this yaml, make sure to install the AMQ Streams using the OCP UI and essentially just accept the defaults (unless there are things you really want to modify). The installation is essentially just a 1 click installation which is really nice, which is why I usually explain it that way.

You could also install via yaml instead of using the OCP UI and you can find instructions for that here: https://access.redhat.com/documentation/en-us/red_hat_amq_streams/2.1/html/deploying_and_upgrading_amq_streams_on_openshift/deploy-tasks_str#doc-wrapper
