To make sure CodeReady Containers can run on a typical laptop, some resource-heavy services get disabled by default. One of these is Prometheus and the related monitoring, alerting, and telemetry functionality. Telemetry functionality is responsible for listing your cluster in the Red Hat OpenShift Cluster Manager.

You must assign additional memory to the CodeReady Containers virtual machine. At least 12 GiB of memory (a value of

Procedure
List unmanaged Operators and note the numeric index for
