Exercise 8.3: Creating a Persistent Volume Claim (PVC)

CP 노드에 연결된 터미널로 이동
생성된 PVC가 있는지 확인
```
kubectl get pvc
```

PVC 생성

cat <<EOF | kubectl create -f -
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: pvc-one
spec:
  accessModes:
  - ReadWriteMany
  resources:
     requests:
       storage: 200Mi
EOF

생성된 PVC 확인
```
kubectl get pvc pvc-one
```
이전 실습에서 생성된 PV 확인
```
kubectl get pv nfs
```

Deployment 생성

cat <<EOF | kubectl create -f -
apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    run: nginx
  name: nginx-nfs
spec:
  selector:
    matchLabels:
      run: nginx
  template:
    metadata:
      labels:
        run: nginx
    spec:
      containers:
      - image: nginx
        imagePullPolicy: Always
        name: nginx
        volumeMounts:
        - name: nfs-vol
          mountPath: /opt
        ports:
        - containerPort: 80
          protocol: TCP
      volumes:
      - name: nfs-vol
        persistentVolumeClaim:
          claimName: pvc-one
EOF

생성된 Pod 확인
```
kubectl get pod -l run=nginx
```

생성된 Pod 상세 내용 확인

kubectl describe pod POD_NAME

kubectl describe pod $(kubectl get pod -l run=nginx -o=jsonpath='{.items[0].metadata.name}')

Pod가 생성되지 않을 경우에는 이유를 찾아서 고치세요
PVC 상태 확인
```
kubectl get pvc pvc-one
```
