summary
Open source block storage for Kubernetes implemented as per-volume microservices with about 40,000 lines of Go and a CSI driver; installs with one-click install (Helm or Rancher) and exposes iSCSI/TGT block devices. It provides incremental backups to S3/NFS, recurring snapshots, cross-cluster disaster recovery that restores WordPress+MariaDB in the demo, and live upgrades without stopping volumes. Current release is 0.7.0 beta with ~900 GitHub stars at the time.
