This change updates the machine controller manager components for Azure with several important improvements and bug fixes. The Azure provider is upgraded from v0.17.2 to v0.18.0, while the core machine controller manager receives patch updates to v0.60.1 and v0.60.2. These changes enhance VM deployment capabilities, improve resource cleanup, and fix critical stability issues.

Walkthrough

  • New Feature: Added support for deploying Azure VMs into capacity reservations, providing better resource allocation control
  • Bug Fix: Fixed orphan safety controller pagination issue that prevented complete cleanup of orphaned VM instances in large Azure clusters
  • Bug Fix: Added safeguards to prevent VM orphaning during machine deletion and fixed provider initialization panics
  • Chore: Enhanced build workflow with ARM64 image support and improved resource cleanup for failed VM creation attempts
