Issues

• OsDisk's created during the creation of the LinxuVM don't get destroyed at the end
  • Disclaimer from https://www.pulumi.com/registry/packages/azure/api-docs/compute/linuxvirtualmachine/ mention that this should happen automatically
  • Currently trying to set up a custom provider to compare the behaviour
    • warning: provider config warning: Argument is deprecated

To Do's

• Provide boostrap for ControlPlane node & worker nodes
• Provide easy to use scaling mechanism via pulumi
  • new nodes need to automatically join the cluster
• Refactor code if needed and make it more generic and usable
• Write documentation
