DEMO STEPS
****************
Step 1: Access & Inspect the Kubernetes Cluster
$ kubectl cluster-info
$ kubectl get nodes
$ kubectl get pods -n kube-system
Step 2: Create the Underlying Storage System (Local Storage)
In Worker 1
$ mkdir -p /pv/pv-1
In Worker 2
$ mkdir -p /pv/pv-2
$ mkdir -p /pv/pv-3
Step 3: Create and Apply “Persistent Volumes” using YAML Manifest
Create pv-1, pv-2, pv-3
Sample PV manifest
===============================================
apiVersion: v1
kind: PersistentVolume
metadata:
name: pv-1
spec:
accessModes:
ReadWriteMany
capacity:
storage: 1Gi
persistentVolumeReclaimPolicy: Retain
volumeMode: Filesystem
local:
path: /pv/pv-1
nodeAffinity:
required:
nodeSelectorTerms:
matchExpressions:
key: kubernetes.io/hostname
operator: In
values:
worker01.kubernetes.com
================================================
Step 4: Create and Apply “Persistent Volume Claims” using YAML Manifest
Create "pvc-claim"
Sample PVC Manifest
======================================
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: pvc-claim
spec:
accessModes:
ReadWriteOnce
volumeMode: Filesystem
resources:
requests:
storage: 2Gi
