You tell Kubernetes what you want, and it goes to work to make it happen. PVC 的全称是：PersistentVolumeClaim（持久化卷声明），PVC 是用户存储的一种声明，PVC 和 Pod 比较类似，Pod 消耗的是节点，PVC 消耗的是 PV 资源，Pod 可以请求 CPU 和内存，而 PVC 可以请求特定的存储空间和访问模式。 On deletion of PVC, pvc should release bound and both pv and pv_data should get deleted My Observation On deleting pvc, pv is not getting deleted immediately at times. You switched accounts on another tab or window. volumeName’ This will return the name of the PV that is bound to the PVC. Improve this answer. volumes[*].

Run the kubectl patch command first to remove the protection mechanism and then delete the PV or PVC. Inspecting Your PVC. 2. spec in PVC is immutable which means you cannot change this value after creation. A symptom of this is that the finalizers never get removed. 06 in my kubernetes cluster. 本文主要讲解了PV、PVC、StorageClass的理论和实战。一句话总结：PV、PVC是K8S用来做存储管理的资源对象，它们让存储资源的使用变得可控，从而保障系统的稳定性、可靠性。StorageClass则是为了减少人工的工作量而去自动化创建PV的组件。先规划→后申请→再使用。 Configuring a PVC is like filling out a wish list.

Before you begin You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster. /cluster/kubectl. We can achieve that by presenting the PVC information using kubectl get. kubectl Data Center Automation (DCA) provides lifecycle management at scale across heterogeneous virtual and physical servers, databases, and middleware applications in the most diverse IT environments. You can then re-use the PV configuration to create a PVC则是用户对存储资源的一个“申请”，就像Pod消费Node资源一样，PVC能够消费PV资源。PVC可以申请特定的存储空间和访问模式。 通过kubectl create命令创建成功后，查看StorageClass列表，可以看到名为gold的StorageClass被标记为default： kubectl get deploy <deployment-name> -n <your-namespace> -o yaml > deploy-output. sunny@dev-lab:~$ kubectl get pv NAME CAPACITY ACCESS MODES RECLAIM POLICY STATUS CLAIM STORAGECLASS REASON AGE pv-for Get the Deployment configuration to identify which PVC it uses: kubectl get deployment -o jsonpath="{. kubectl patch pvc <pvc-name> -p '{"metadata":{"finalizers": null}}' kubectl scale --replicas=0 deployment/starterservice kubectl scale --replicas=1 deployment/starterservice I was wondering if there was a way to get kubectl rollout restart to wait for the old pod to terminate before starting a new one?
