与普通的Volume不同,PV是Kubernetes中的一个资源对象,创建一个PV相当于创建了一个存储资源对象,这个资源的使用要通过PVC来请求。 PersistentVolumeClaim。PVC是用户对存储资源PV的请求,根据PVC中指定的条件Kubernetes动态的寻找系统中的PV资源并进行绑定。目前PVC与PV匹配可以通过StorageClassName、...

While existing in-tree persistent volumes continue to function, starting with version 1.26, AKS will no longer support volumes created using in-tree driver and storage provisioned for files and disk. The default class will be the same as managed-csi. Effective starting with Kubernetes version ...
可以将In-Tree理解为将实现代码放在 Kubernetes 代码仓库中;而Out-Of-Tree则表示代码实现与 Kubernetes 本身解耦,存放在 Kubernetes 代码仓库之外。 小结 乍一看,Kubernetes 支持的存储卷类型太多了,对于不熟悉的同学可能感到无从下手。然而,总结起来其实主要有两种类型: ...
Volume地址: https://kubernetes.io/docs/concepts/storage/volumes/ 容器中的磁盘文件是临时的,这对于在容器中运行的非平凡(重大)应用程序会带来一些问题: (1)容器崩溃时文件丢失。 (2)Kubelet重新启动容器后为clean状态。 在Pod中一起运行的容器之间共享文件时,会出现第二个问题。 Kubernetes的Volume抽象地解决了...
I'm not sure if I have to manually create a specific persistent volume and storage class in Kubernetes, but I don't think that is the case as the documentation doesn't mention that as a prerequisite or state that I need to configure that myself. (In any case, my cluster does have ...
To implement a volume in a Kubernetes cluster, you need to define a persistent volume claim for a specific storage class. A storage class represents the characteristics of the underlying storage, such as performance or support for shared access. Persistent volume claim inclu...
这个叫做my-claim的PVC,告诉一个叫做google-storage的 Storage Class,自己需要500Mi的存储空间。 这个叫做google-storage的Storage Class,指定了一个叫做http://kubernetes.io/gcd-pd的自动资源分配器provisioner,执行my-claim所需资源的分配。Kubernetes支持很多内建的Provisioner,可以看这里。
PVC与PV运作过程(图片来自《Kubernetes in Action》) 2.3 PV、PVC示例 这里以NFS+PV+PVC为例进行说明, NFS搭建过程请参考附录2,根据考附录3nginx-pv-pvc.yaml,创建nginx(deployment)、nginx-pv(pv)、nginx-pvc(pvc)。nginx-pv挂载在/nfs/data/nginx 下。在/nfs/data/nginx下创建文件1.html,pod中也可以访问...
