pv-migrate is a CLI tool/kubectl plugin to easily migrate the contents of one Kubernetes PersistentVolumeClaim to another. On Kubernetes, if you need to rename a resource (like a Deployment) or to move it to a different namespace, you can simply create a copy of its manifest with the new namespace and/or name and apply it. However, it is not as simple with PersistentVolumeClaim resources: They are not only metadata, but they also store data in the underlying storage backend. In these cases, moving the data stored in the PVC can become a problem, making migrations more difficult.
Features
- Supports in-namespace, in-cluster as well as cross-cluster migrations
- Uses rsync over SSH with a freshly generated Ed25519 or RSA keys each time to securely migrate the files
- Allows full customization of the manifests (e.g. specifying your own docker images for rsync and sshd, configuring affinity etc.)
- Supports multiple migration strategies to do the migration efficiently and fallback to other strategies when needed
- Customizable strategy order
- Supports arm32v7 (Raspberry Pi etc.) and arm64 architectures as well as amd64
- Supports completion for popular shells: bash, zsh, fish, powershell
