Describe the bug
Auto-upgrade for Kubernetes patch versions is not being triggered when using an Auto Upgrade Profile with TargetKubernetesVersion, even though newer patch versions are available and the cluster is properly linked to the update strategy. Node image auto-upgrades are working as expected.
To Reproduce
Steps to reproduce the behavior:
Configure an Auto Upgrade Profile:
Channel: TargetKubernetesVersion
Node image: Latest
Target Kubernetes minor version: 1.33
Long-term support: Disabled
Link the AKS cluster to the update strategy.
Ensure the cluster is running version 1.33.5.
Verify that newer patch versions are available (e.g. 1.33.6, 1.33.7).
Observe update runs:
Node image auto-upgrade is triggered.
No auto-upgrade run is triggered for Kubernetes patch versions.
Expected behavior
When using TargetKubernetesVersion with minor version 1.33, the cluster should automatically upgrade to the latest available patch version (e.g. from 1.33.5 → 1.33.6 → 1.33.7) without manual intervention.
Screenshots
N/A (can be provided if needed)
Environment (please complete the following information):
Kubernetes version: 1.33.5
Node image auto-upgrade is functioning correctly:
auto-auto-upgrade-node-image-nuk-nodeimage-48qj0p
Status: Pending
Type: Node image version only
Patch version auto-upgrade is not triggering at all despite newer versions being available.
The cluster is correctly linked to the update strategy.
Behavior suggests patch upgrades are not being picked up/executed under TargetKubernetesVersion channel.
