terraform-azurerm-linux-vm

Description

Pass in a single name to create a VM, or a list of names to create a group of VMs.

The defaults object is defined in lockstep with the same object in the VM module so that they can share the same local.

This is a WORK IN PROGRESS and will definitely change. Currently only supports custom images.

Example

The example uses a number of modules from this organisation.

Note that (currently) you must have a custom image or shared image.

Futures

Depends on the issues raised, but the following are definitely on the list:

1. data disks
2. platform images
3. custom extensions
4. cloud-init
