The Using Quarkus applications with Kafka instances and Red Hat OpenShift Service Registry quickstart in https://console.redhat.com/application-services/learning-resources misses required authorization information and instructions. This causes the quickstart to fail.

On Kafka, the following CLI command needs to be executed to configure the required Kafka ACLs for the quickstart:

rhoas kafka acl grant-access --producer --consumer --service-account $CLIENT_ID --topic quotes --group quarkus-service-registry-quickstart-consumer

On Service Registry, the service account needs at least the manager role, so the producer is able to store the generated schema in Service Registry, and the consumer can fetch the schema from Service Registry.

rhoas service-registry role add --role=manager --service-account=$CLIENT_ID
