Dynamic storage provisioner:<\/strong> openebs.io\/local<\/code>
Lab platform:<\/strong> Self-managed Kubernetes v1.35.10 on Ubuntu Linux (kubeadm or other manual installation)
OpenEBS release referenced:<\/strong> OpenEBS 4.6.2 (HostPath engine v4.6.0), current as checked on November 12, 2026
Lab target:<\/strong> Three StatefulSet replicas, each with its own dynamically provisioned 1Gi Local PV backed by a directory on a worker node
Difficulty:<\/strong> Beginner to intermediate
Scope:<\/strong> A lightweight OpenEBS Local PV HostPath-only<\/strong> installation; no EKS, AKS, GKE, Ceph, LVM, ZFS, or Mayastor required.<\/p>\n\n\n\n

\n

Important:<\/strong> All commands are examples to run against your cluster<\/strong>, not commands already executed. Verify your kubectl<\/code> context and node status before applying anything. A 1Gi PVC represents a requested size; without filesystem quotas it does not impose a 1Gi disk-use limit<\/strong>. The backing storage is node-local, not replicated or highly available.<\/p>\n<\/blockquote>\n\n\n\n
