The migrate-controller component is developed by Alibaba Cloud based on the open source project Velero. You can use this component to migrate Kubernetes applications. This topic lists the latest changes to migrate-controller.
Introduction
For more information about how to install migrate-controller, see Install the application backup component.
Velero is a cloud-native tool that can be used to back up, restore, and migrate applications
in Kubernetes clusters. Velero is written in Go. Velero ensures data security when
you use it to back up, restore, and migrate applications and persistent volumes (PVs)
in ACK clusters. For more information about the source code of the Velero project,
see Velero. For more information about the source code of the Velero plug-in for Alibaba Cloud,
see velero-plugin.
Note Velero requires Kubernetes versions later than V1.10.
Usage notes
You can use migrate-controller to back up, restore, and migrate applications. For more information, see Back up and restore applications and Migrate applications across clusters.
