ACK Edge is a cloud-managed solution provided by Container Service for Kubernetes (ACK) for collaborative cloud-edge computing. These release notes cover ACK Edge clusters of Kubernetes 1.28.
What's new
| Feature | Description |
|---|---|
| Cluster version | 1.28.9-aliyun.1 |
| Autonomy of edge nodes | Two improvements strengthen node autonomy observability and reliability:<br><br>Autonomy Condition: A new node condition, Autonomy Condition, is added to each edge node. It reports the node's real-time autonomy status, so you can accurately determine whether a node is operating autonomously.<br><br>AOF persistence for failed keys: A new file /var/lib/edge-hub/autonomy/aof persists failed keys and errors, making autonomy issues easier to troubleshoot. |
| Component management | The edge-cloud-provider-manager component is released in this version. It handles cluster cloud resource management for ACK Edge clusters. For more information, see edge-cloud-provider-manager. |
| Multi-region workloads | Workload templates now support StatefulSets. This extends multi-region workload management to stateful applications. For more information, see Node pool application set management. |
| Node access | Two kubelet parameter changes take effect in this version:<br><br>Resource reservation policy updated: The node resource reservation policy is updated. Review the updated policy before upgrading to make sure your workload resource requests remain compatible. For more information, see Resource reservation policy.<br><br>Unsafe port 10255 closed by default: kubelet now closes port 10255 by default. If your monitoring agents, health checks, or metrics scrapers poll this port, they will lose connectivity after the upgrade. Reconfigure those tools before upgrading. |
Important
Closing port 10255 is a behavioral change that silently breaks any tooling that reads kubelet metrics or health endpoints on that port. Audit your monitoring stack and update it before upgrading to this version.
