Local Path Provisioner

Purpose: Persistent storage for stateful applications

Version: v0.0.24 (Helm chart: local-path-provisioner)

Namespace: local-path-storage

Description​

Provides persistent volumes using local disk storage on nodes. Simple and efficient storage solution for development clusters.

Installation​

Installed via ArgoCD from Helm chart: rancher/local-path-provisioner

Storage Class​

kubectl get storageclass
# NAME         PROVISIONER             RECLAIMPOLICY   VOLUMEBINDINGMODE
# local-path   local-path-provisioner   Delete          WaitForFirstConsumer

Usage​

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: my-pvc
spec:
  storageClassName: local-path
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi

Storage Location​

Data is stored at: /var/lib/local-path-provisioner/

How It Works​

  1. PVC is created with storageClassName: local-path
  2. Provisioner creates PV with local path on node
  3. Pod mounts the PV

Use Cases​

  • Prometheus/Grafana persistent data
  • Databases requiring persistent storage
  • Development workloads

Limitations​

  • Not suitable for multi-node read/write (single node only)
  • Data not replicated across nodes
  • Not production-grade for critical data
