Playground AKS Storage

Playground for AKS and storage options. This repository contains examples how to use static or dynamic provisioning using different combinations of Azure storage services. This includes Azure Files and Azure NetApp Files with different protocols like NFSv4.1 or SMB. You can then performance test your storage setup, to see if you get the throughput you need. Example performance testing numbers has been put to notes.

Usage

1. Clone this repository to your own machine
2. Open Workspace

• Use WSL in Windows
• Requires Bash

3. Open setup.sh to walk through steps to deploy this demo environment

• Execute different script steps one-by-one (hint: use shift-enter)
