How to attach a disk in Kubernetes cluster in azure (AKS)

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.

Based on Kubernetes 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
