Using Kubernetes Local Storage for Scale-Out Storage Services
summary
Shows how Kubernetes runs scale-out stateful services on true local disks: clusters with 19 nodes automatically run a node-prep daemonset → label → local-volume-provisioner handoff, discovering and creating 95 local persistent volumes from mounted HDDs and SSDs. Uses the Kubernetes Local Persistent Volumes beta (v1.10) and the open-source local volume provisioner; operation requires admin node prep (format/mount) today and lacks dynamic provisioning and integrated health checks, though raw block and LVM dynamic provisioning are on the roadmap.
