Useful Resources: Persistent Volumes Claim

题干

For this question, please set this context (In exam, diff cluster name)

kubectl config use-context kubernetes-admin@kubernetes

A persistent volume named red-pv-cka is available. Your task is to create a PersistentVolumeClaim (PVC) named red-pvc-cka and request 30Mi of storage from the red-pv-cka PersistentVolume (PV).
Ensure the following criteria are met:

• Access mode: ReadWriteOnce
• Storage class: manual

解题思路

1. 切换集群环境

kubectl config use-context kubernetes-admin@kubernetes

2. 编写pvc资源清单，内容如下：

apiVersion: v1
kind: PersistentVolumeClaim
metadata:name: red-pvc-cka
spec:accessModes: - ReadWriteOncevolumeName: red-pv-ckastorageClassName: manualresources:requests: storage: 30Mi

善于利用kubectl explain pvc查看资源清单需要的参数

3. 提交资源清单

controlplane $ k apply -f red-pvc-cka.yaml 
persistentvolumeclaim/red-pvc-cka created

4. 查看pvc资源创建情况

controlplane $ k get pvc
