Read in order, or jump to what you need.
Why ROSA is different
By the end of this lesson, you will be able to explain why a ROSA cluster connects against an OCM organisation rather than its AWS account, why an OCM credential cannot read the cluster, and what a 424 on the workload view means.
The three connection methods
By the end of this lesson, you will be able to choose between the automatic, cluster-login and service-account methods, identify which one writes to the customer's cluster, and explain why provisioning is explicit and per-cluster.
Discovery and the workload view
By the end of this lesson, you will be able to predict what ROSA discovery returns, recognise the five OpenShift-native kinds in the workload view, and handle a cluster whose API server is private.
Configuration through OCM
By the end of this lesson, you will be able to resize a worker pool and edit the cluster autoscaler through OCM, explain which settings each topology exposes, and name what the integration refuses to do.
