Alibaba Cloud provides the virtual-kubelet-autoscaler add-on for clusters of Container Service for Kubernetes (ACK) clusters. If pods fail to be scheduled to existing Elastic Compute Service (ECS) worker nodes due to insufficient node resources, virtual-kubelet-autoscaler reschedules the pods to virtual nodes provided by elastic container instances (ECIs).
Prerequisites
- A managed Kubernetes cluster is created. For more information, see Create a cluster of ACK Managed Edition.
- A virtual node is deployed in the cluster. For more information, see Deploy ack-virtual-node in an ACK cluster.
