The microprofile-reactive-messaging-kafka quickstart instructs users to install the Kafka operator globally (cluster-wide), which causes problems for users working on shared
OpenShift clusters.

Current behavior

The quickstart documentation and YAML files perform a global operator installation:

Documentation (helm-install-prerequisites-openshift.adoc):

• Requires cluster admin privileges
• No mention of namespace-scoped installation option

YAML file (charts/amq-operator-on-openshift.yaml):

  apiVersion: operators.coreos.com/v1alpha1
  kind: Subscription
  metadata:     name: amq-streams
    namespace: openshift-operators  # Global installation
  spec:     channel: stable
    installPlanApproval: Automatic
    name: amq-streams
    source: redhat-operators
    sourceNamespace: openshift-marketplace
  

• Contains only Subscription resource
• Uses openshift-operators namespace (global installation)
• Missing OperatorGroup (not needed for global, but indicates global install)

Problems

• Requires cluster admin privileges - Many users don't have admin access on shared clusters
• Global operator installation affects all users and namespaces on the cluster
• Conflicts on shared clusters - Multiple users cannot run the quickstart simultaneously
• Impossible to properly clean up - Global operator remains after quickstart completion
• Breaks user isolation - One user's operator installation affects others
• Not suitable for CI/CD - Cannot run in parallel test environments

Expected behavior

• Quickstart should use namespace-scoped operator installation
• Should not require cluster admin privileges
• Each user should be able to install operator in their own namespace
• Documentation should guide users through namespace-scoped installation
• Cleanup should completely remove all operator resources from user's namespace
• Multiple users should be able to run quickstart simultaneously without conflicts
