Moving data into Kubernetes w/ Rsync

While VolSync is typically used to replicate data between Kubernetes clusters, it is sometimes necessary to replicate data into a cluster from outside. For example, when containerizing a previously standalone workload, that application’s data needs to be moved into the cluster and onto a PVC.

In this configuration, VolSync manages the destination (via a ReplicationDestination object), but instead of having a VolSync ReplicationSource as the sender, it will be an external program that plays that role. It will transmit the data to the destination by initiating the Rsync over SSH connection directly.

The VolSync CLI incorporates this functionality via its migration set of sub-commands. For more information and a walk-through of how to perform synchronization of data into a Kubernetes PVC, please see:
