Introduction

This action leverages Azure API to manipulate the state of Azure scale set instances / virtual machines. More specifically, it can reboot, delete, stop or deallocate them.

Use Cases

• Verify auto-scaling of a Kubernetes node group.
• Understand how pods are shifted across different nodes within a Kubernetes cluster.
• Verify that system services come up on system start.
• Check that your monitoring solution informs you about this occurrence.

Rollback

Note that this attack does not support any rollback. The attack only transmits the API call, e.g., Stop or Delete virtual machine.

Parameters

Parameter	Description	Default
Action	How the scale set instance state should be changed. Reboot, delete, stop or deallocate.
