ReplicaScheduling focus on dealing with the number of replicas testing when propagating resources that have replicas
|
||||
in spec (e.g. deployments, statefulsets) to member clusters with ReplicaSchedulingStrategy.
|
||||
Test Case Overview:
|
||||
Case 1:
|
||||
`ReplicaSchedulingType` value is `Duplicated`.
|
||||
Case 2:
|
||||
`ReplicaSchedulingType` value is `Duplicated`, trigger rescheduling when replicas have changed.
