Challenge 10 - Configure VM Scale Set to run a Web Server

< Previous Challenge - Home - Next Challenge>

Introduction

The goals of this challenge include understanding:

• How extensions are configured in a VMSS
• How the custom script extension works in the context of a VMSS
• Custom script extension does not lock deployment order
• Staging artifacts in a location accessible to the Azure Resource Manager

Description

We have provided a script (install_apache_vmss.sh) that configures web servers in a VMSS. When run on an individual VM instance, the script deploys a static web page that should be available at: http://<PublicIPofTheLoadBalancer>/wth.html

This script is similar to the one used earlier in Challenge 6. However, it has some differences that take into account how the script will be executed on a VM that is part of scale set.

You can find the script in the Resources folder for ARM-Challenge-10.

Your challenge is to:

• Extend the ARM Template to configure a webserver on the VM instances of the VM Scale Set you deployed earlier
  • Host the script file in a secure artifact (staging) location that is only accessible to the Azure Resource Manager.
  • Pull the website configuration script from the artifact location.

Success Criteria

1. Verify you can view the web page configured by the script

Tips

• Use an Azure Blob Storage account as the artifact location
• Secure access to the artifact location with a SAS token
• Pass these values to the ARM Template as parameters
