Скачать или смотреть DataSource and DataSourceRef for PVC resources | Writing a K8S Volume Populator from scratch - 1

This video is the first video in the series where we are going to write a Volume Populator from scratch, and in this video we looked into the DataSource and DataSourceRef field of PVC resource.
We talked about these resources in details for example how they can be used to create volume from existing PVC or volume snapshot resource.
A part from that we also talked about the difference between these two fields of PVC resource and the feature gates they depend on.
