Managing VM Images may be a nightmare. Here are 6 simple approaches on how to seamlessly build, share, test, and copy images in Azure. And as a bonus, you also get how to build image notifications based on Event-Driven-Architecture.

Problem

Whether you are managing 100 Virtual Machines or 1000+ that build and harden VM images, do you manually manage your images? If you do, you know that it is quite expensive and leads to hard-to-detect errors and potential security vulnerabilities.

Here is how I approach this issue for my customers. My procedure of creating image management for Azure.

The ARM template is quite simple it contains following properties:

  • Identity section is required, you have to create Managed Identity for image builder to have an access to create and edit images
  • _VmProfile _is to set up VM configuration plan
  • _Source _allows you to specify base image parameters. I use the latest Ubuntu Server 18.04 LTS from Canonical
  • Customization section allows you to specify VM hardening scripts.
  • Customization section allows you to specify VM hardening scripts.

Advantages

Templates and process itself is easy to understand and it can be easily integrated with Azure DevOps.
