Local Path Provisioner

Overview

Local Path Provisioner provides a way for the Kubernetes users to utilize the local storage in each node. Based on the user configuration, the Local Path Provisioner will create hostPath based persistent volume on the node automatically. It utilizes the features introduced by Kubernetes Local Persistent Volume feature, but make it a simpler solution than the built-in local volume feature in Kubernetes.

Compare to built-in Local Persistent Volume feature in Kubernetes

Pros

Dynamic provisioning the volume using host path.

• Currently the Kubernetes Local Volume provisioner cannot do dynamic provisioning for the host path volumes.

Cons

1. No support for the volume capacity limit currently.
   1. The capacity limit will be ignored for now.
2. Only support hostPath

Requirement

Kubernetes v1.12+.

Deployment

Installation

In this setup, the directory /opt/local-path-provisioner will be used across all the nodes as the path for provisioning (a.k.a, store the persistent volume data). The provisioner will be installed in local-path-storage namespace by default.

kubectl apply -f https://raw.githubusercontent.com/rancher/local-path-provisioner/master/deploy/local-path-storage.yaml

After installation, you should see something like the following:

$ kubectl -n local-path-storage get pod
NAME                                     READY     STATUS    RESTARTS   AGE
local-path-provisioner-d744ccf98-xfcbk   1/1       Running   0          7m

Check and follow the provisioner log using:

$ kubectl -n local-path-storage logs -f local-path-provisioner-d744ccf98-xfcbk
