kubernetes | Kubernetes: kubernetes_persistent_volume | docs-kubernetes-resource-persistent-volume-x | A Persistent Volume (PV) is a piece of networked storage in the cluster that has been provisioned by an administrator. |
kubernetes_persistent_volume
The resource provides a piece of networked storage in the cluster provisioned by an administrator. It is a resource in the cluster just like a node is a cluster resource. Persistent Volumes have a lifecycle independent of any individual pod that uses the PV.
More info: https://kubernetes.io/docs/concepts/storage/persistent-volumes/
Example Usage

metadata {
name = "terraform-example"
}
spec {
capacity {
storage = "2Gi"
}

vsphere_volume {
volume_path = "/absolute/path"
}
}
}
}
