v2.6.0

registry-cn-hangzhou.ack.aliyuncs.com/acs/cloud-controller-manager-amd64:v2.6.0

March 2, 2023

• New features:

  • The alpha.service-controller.kubernetes.io/exclude-balancer tag for excluding nodes from the SLB backend is deprecated. Use the new node.kubernetes.io/exclude-from-external-load-balancers tag instead.

  • SLB supports configuring both TCP and UDP protocols for a single listener.

  • CLB supports disabling TCP and UDP health checks using the service.beta.kubernetes.io/alibaba-cloud-loadbalancer-health-check-switch annotation.

  • CLB supports configuring the Proxy Protocol for TCP and UDP listeners of a CLB instance using the service.beta.kubernetes.io/alibaba-cloud-loadbalancer-proxy-protocol annotation.

    Important

    This feature does not support smooth online migration. Switching to the Proxy Protocol requires service downtime for the upgrade. Configure this with caution.

  • CLB supports verifying the certificate validity period when synchronizing HTTPS listeners. If a certificate expires, the CLB synchronization fails.

  • NLB supports setting security groups for an NLB instance using the service.beta.kubernetes.io/alibaba-cloud-loadbalancer-security-group-ids annotation.

• Optimizations:

  • The resource lock for CCM leader election is switched from endpointsleases to leases to reduce primary/secondary switchovers.

  • Optimizes the load balancer synchronization logic. When the load balancer's own properties, such as its name or resource group, fail to update, the vServer group continues to be updated.

  • Optimizes the criteria for determining node changes to reduce the number of service synchronizations.

• Fixed issue:

  Fixed an issue that occasionally caused nodes to be misidentified as NotReady.

  • ACK supports creating different types of cloud resources based on the spec.loadBalancerClass field of a service. If this field is not set, a CLB instance is created by default. If it is set to alibabacloud.com/nlb, an NLB instance is created. This feature is supported only in Kubernetes 1.24 and later.

• Optimizations:

  • Fixed an issue where a reused IPv6 SLB instance could not be deleted.

• New features:

  • Supports setting deletion protection for an SLB instance using the annotation service.beta.kubernetes.io/alibaba-cloud-loadbalancer-delete-protection. Deletion protection is enabled by default for new SLB instances.

  • Supports setting configuration read-only mode for an SLB instance using the annotation service.beta.kubernetes.io/alibaba-cloud-loadbalancer-modification-protection. Configuration read-only mode is enabled by default for new SLB instances.

  • Supports specifying the resource group of an SLB instance using the annotation service.beta.kubernetes.io/alibaba-cloud-loadbalancer-resource-group-id. This takes effect only at creation and cannot be modified.

  • Supports specifying the name of an SLB instance using the annotation service.beta.kubernetes.io/alibaba-cloud-loadbalancer-name.

  • Alibaba Cloud product OpenAPI calls are changed from public network to internal network, removing the public network dependency for CCM (supported in all regions).

  • A tag is added by default to the SLB instance created for a LoadBalancer service. The format is ack.aliyun.com: {your-cluster-id}. This takes effect only for new clusters.

  • Compatible with the community provider ID naming convention <cloudProvider>://<optional>/<segments>/<provider id>.

  • For new Terway clusters, LoadBalancer services default to mounting pods directly to the SLB backend. For new ACK clusters in Terway network mode, if the service type is LoadBalancer, the pod's ENI IP is mounted as the load balancer's backend by default to improve network performance. For LoadBalancer services, a string type for targetPort is not supported.

• Optimizations:

  • Upgrades the base image to Alpine 3.11.6.

  • Supports exposing the synchronization process between a service and a LoadBalancer as an event.

• Optimizations:

  • Optimized the weight calculation method for Services in Local mode (externalTrafficPolicy=Local) to improve load balancing among pods. For more information, see How to automatically set node weights in Local mode?.

  • Optimizes cloud product API calls to improve efficiency and reduce the risk of throttling.

  • When a node has the service.beta.kubernetes.io/exclude-node tag, the associated route is no longer deleted when the node is deleted.

December 31, 2019

• Configures VSwitchIds. CloudConfig supports adding IDs in the :vswitchid1,:vswitchid2 format.

• Adds a backoff mechanism for retries when OpenAPI calls are throttled. Requests are re-added to the reconcile queue at intervals of 30s to 180s.

• Adjusts the number of Reconcile worker threads to 2 to maximize the use of the OpenAPI QPS quota and improve the Reconcile speed.

• Fixed a CCM crash caused by concurrent map reads and writes in the aliyungo SDK.

• When a node is removed from a Kubernetes cluster, CCM automatically deletes the corresponding VPC route table entry for that node.

• Fixed an issue where the port configuration for HTTP Forward could not be changed due to port forwarding dependencies.

• If the SLB backend type is ECS, the serverip field does not need to be checked when updating the SLB backend servers. This avoids backend addition failures caused by changes in the default value of the OpenAPI serverip field.

• The corresponding VPC route table entry for a node is added only when the node's status is known.

• CCM no longer adds NAT IP addresses to node metadata, fixing an occasional issue where the API server could not access the kubelet.

• When changing the listener configuration, the start listener OpenAPI is called only when the listener status is inactive. This avoids triggering OpenAPI throttling issues.

  • SLB instances created by a Kubernetes service cannot be reused. This can cause the SLB instance to be accidentally deleted. You can only reuse SLB instances that you manually create in the console or by calling the OpenAPI.

  • Multiple services that reuse the same SLB instance cannot have the same frontend listener port. Otherwise, a port conflict will occur.

  • When you reuse an SLB instance, use the listener name and vServer group name as identifiers. Do not modify the names of the listener and vServer group.

• When a node's label changes, the SLB backend is automatically processed to synchronize the addition or removal of the corresponding node.

• Supports Session Sticky.

• Services created by specifying an existing SLB instance no longer process listeners. You need to add SLB listeners yourself.

This upgrade does not affect your services.
