Kubectl：如何从命令行创建持久卷的清单？

Question

是否可以从命令行创建（启动清单）pv/pvc？

IE。创建部署

kubectl create deployment abc --image=logger:1 --dry-run=client -o yaml > abc.yml

IE。创建一个 Pod

kubectl run pod xyz --image=logger:1 --dry-run=client -o yaml > xyz.yml

我正在尝试做什么

kubectl create persitentvolume --name my-pv spec.capacity.storage=1Gi --dry-run=client -o yaml > my-pv.yml

We cannot create the manifest file for `pv` using the command line. For only the following objects created using the command line(imperatively) is possible. 

     --->kubectl create [press tab] [press tab] 
    clusterrole          cronjob              namespace            quota                secret               
    clusterrolebinding   deployment           poddisruptionbudget  role                 service              
    configmap            job                  priorityclass        rolebinding          serviceaccount   

或者您可以使用--helpwithkubectl create检查可用选项。
