MachineHealthCheck is the solution provided by Cluster API for automatic replacement of faulty nodes. AKE uses Cluster API to deploy and manage AKE workload clusters and automatically integrates the MachineHealthCheck function. Users can configure faulty node detection conditions and automatic replacement thresholds for each VM-based node group through the AKE UI. When AKE detects that a node meets the faulty node detection conditions and automatic replacement threshold, it automatically deletes the faulty node and its corresponding virtual machine, and creates a new node to replace this faulty node, ensuring high availability of the cluster.
