Maybe I am misunderstanding this. According to the official documentation, you can create a PersistentVolume with the intent to use it with specific PersistentVolumeClaims. To achieve this, one has to use “prebinding”.
On the other hand, one can use selectors when creating a PVC to bind to a specific PV. Thus, no need for prebinding. If the intent of the feature-set is to allow the ability to use a specific storage backend, I am a little confused by the need for prebinding.
Can someone please help what use case PV → PVC prebinding is even needed when PVC → PV binding can be controlled?
Appreciate the help in advance.
