如何在 azure (AKS) 中的 Kube.netes 集群中附加磁盘

Question

I have deployed my running application in AKS. I want to add new disk (Harddisk of 30GB) but I don't know how to do it.

I want to attach 3 disks.

Here is details of AKS:

• Node size: Standard_DS2_v2
• Node pools: 1 node pool
• Storage is:

---

default (default)   kubernetes.io/azure-disk   Delete          WaitForFirstConsumer   true

Please, tell me how to add it.

Answer 1

Based on Kube.netes documentation :

A PersistentVolume (PV) is a piece of storage in the cluster that has been provisioned by an administrator or dynamically provisioned using Storage Classes .

It is a resource in the cluster just like a node is a cluster resource. PVs are volume plugins like Volumes, but have a lifecycle independent of any individual Pod that uses the PV.

In the Azure documentation one can find clear guides how to:

• create a static volume using Azure Disks
• create a static volume using Azure Files
• create a dynamic volume using Azure Disks
• create a dynamic volume using Azure Files

NOTE : Before you begin you should have existing AKS cluster and Azure CLI version 2.0.59 or later installed and configured. To check your version run:

az --version

See also this documentation .

Answer 2

A persistent volume represents a piece of storage that has been provisioned for use with Kube.netes pods. A persistent volume can be used by one or many pods, and can be dynamically or statically provisioned .

This article shows you how to dynamically create persistent volumes with Azure disks for use by a single pod in an Azure Kube.netes Service (AKS) cluster.

But if your requirement is to share the persistent volume across the multiple nodes use Azure FileShare

This article shows you how to dynamically create an Azure Files share for use by multiple pods in an Azure Kube.netes Service (AKS) cluster.
