  5. For Storage account, select Use existing.
  6. For File share, select Create new and give it a name of "fileshare".
  7. Click Create storage.
Set Resource Variables in Cloud Shell
  1. In the Azure portal, click the listed resource group name.
  2. Copy it to your clipboard.
  3. In Cloud Shell, set the RG variable, replacing <RESOURCE_GROUP_NAME> with the name you just copied.
  4. In the Azure portal, click the virtual machine provisioned with this lab.
  5. In the left menu, click Properties.
  6. Scroll down and copy the Resource ID to the clipboard.
  7. In Cloud Shell, set the IMAGE variable, replacing <RESOURCE_ID> with the name you just copied.
Create an Image from the VM
  1. Create an image gallery.
  2. Create an image definition.
  3. Create an image version.
Create a Virtual Machine Scale Set from an Image
  1. In the Azure portal, scroll the listed resources and click the new image definition file.
  2. In the left menu, click Properties.
  3. Scroll down and copy the Resource ID to the clipboard.
  4. In Cloud Shell, create a VM scale set, replacing <RESOURCE_ID> in the image variable with the name you just copied.

Additional Resources

You decide that creating an image of a VM is the best solution because you can capture all the custom software and redeploy the image many times.

In order to create an image, you need to create an image gallery. This allows you to share the image with others and refer to it when deploying into a virtual machine scale set.

Once you've created the image gallery, create an image definition to provide detail about the image like the operating system and software installed.

Next, create an image version that you can refer to when you patch the image (e.g., latest, 1.0, etc.).

Finally, create a virtual machine scale set and refer to the image you just created in the previous steps.
