Only letters, digits, hyphens (-), underscores (_), and periods (.) are allowed. A DNS subdomain can be prefixed to a key. Value: Enter 1 to 63 characters starting and ending with a letter or digit. Only letters, digits, hyphens (-), underscores (_), and periods (.) are allowed. Effect: Available options are NoSchedule, PreferNoSchedule, and NoExecute. When creating a node, you can specify an initial value for this field, and this field is not returned during query. When creating a node pool, you can specify an initial value in the node template, and this field is returned during query. In other scenarios, this field is not returned during query. Example: "taints": [{ "key": "status", "value": "unavailable", "effect": "NoSchedule" }, { "key": "looks", "value": "bad", "effect": "NoSchedule" }]

If this parameter is not specified or is set to false, pods can be scheduled to an available node after the Kubernetes node is ready. If this parameter is set to true, pods can be scheduled to an available node only after the Kubernetes node is ready and the post-installation script has been executed.

For nodes running EulerOS 2.5 or EulerOS 2.8, the default container runtime is docker. For nodes running other OSs, the default container runtime is containerd.
initializedConditions	Array of strings	Definition Custom initialization flag, which is left empty by default. Before CCE nodes are initialized, node.cloudprovider.kubernetes.io/uninitialized is added to the nodes to prevent pods from being scheduled to these nodes. When creating a node, you can configure the initializedConditions parameter to control the taint removal time. By default, the timeout period is not configured. Example: Create a node and add "initializedConditions": ["CCEInitial", "CustomedInitial"]. After custom initialization is complete, CCE will call a Kubernetes API (for example, PATCH /v1/nodes/{node_ip}/status) to update the node conditions and add two flags whose type values are CCEInitial and CustomedInitial, respectively, and both status values are True. CCE polls status.Conditions of nodes to check whether there are conditions whose type is CCEInitial or CustomedInitial. If such conditions exist and their statuses are True, the node initialization is complete and the initialization taint will be removed. initializedConditions allows you to configure a timeout interval during node creation. For example, "initializedConditions": ["CCEInitial:15m", "CustomedInitial:15m"] indicates that the timeout interval is 15 minutes. After the timeout interval is reached, the initialization conditions will be automatically ignored and the initialization taint will be removed when CCE polls the node. status: conditions: - type: CCEInitial status: 'True' - type: CustomedInitial status: 'True' initializedConditions ranges from 1 to 99 in the unit of seconds. Each value must be between 1 and 20 characters long and can only contain letters and digits. The maximum number of flags cannot exceed 2. The unit of the timeout interval is minute (m).

The containerBaseSize setting takes effect only on nodes running EulerOS or Huawei Cloud EulerOS 2.0 in clusters of the new version (v1.23.14-r0, v1.25.9-r0, v1.27.6-r0, v1.28.4-r0 or later). This parameter cannot be updated when a node pool is being updated. Options: 10 to 500 Default value: If the value is not specified or is set to 0, the default value is used. The default value is 10 in Device Mapper mode. In OverlayFS mode, the available space of a single container is not limited by default.

Parameter	Type	Description
type	String	Details: Configuration type of the Kubernetes node name. The default value is privateIp. cceNodeName are the same. Node names cannot be changed. Once a VM name is altered on the ECS console, the node name cannot be modified accordingly during ECS synchronization. To prevent conflicts between Kubernetes node names, a suffix is automatically added to the node name of a node configured with cceNodeName. The suffix consists of a hyphen (-) followed by five random lowercase letters and digits (0 to 9). Options: privateIp: Use the private node IP address the as the Kubernetes node name. cceNodeName: Use the CCE node name as the Kubernetes node name. Default value: privateIp

scaleDownUnneededTime	Integer	Details: How long a node should be unneeded before it is eligible for scale in. This parameter specifies the duration during which a node is in the unneeded state before the scale-in operation can be performed. CCE Cluster Autoscaler scales in the node only when the node is not needed for a specified period. This prevents frequent scale-in triggered by temporary resource fluctuations and improves system stability. If this parameter is not specified, the CCE Cluster Autoscaler add-on uses the default time threshold. Options: 0 to 2147483647 NOTE: Note: If the parameter is set to -1, it indicates that the value is empty. Default value: This parameter is left empty by default.
scaleDownUtilizationThreshold	Float	Details: Scale-in utilization threshold of a node, which is defined by the total CPU or memory resources used by all running pods on the node divided by the total available resources of the node. If the calculated value falls below the specified threshold, the node becomes eligible for scale-in. For example, setting this parameter to 0.3 means that if the resource utilization on a node drops below 30%, the node will be scaled in. If this parameter is not specified, the CCE Cluster Autoscaler add-on will use the default utilization threshold. Options: 0 to 1 NOTE: Note: If the parameter is set to -1, it indicates that the value is empty. Default value: This parameter is left empty by default.

**Table 31** NodeManagement
Parameter	Type	Description
serverGroupReference	String	Details: A cloud server group ID. If this parameter is specified, the cloud server group will be associated with the target node pool, and all nodes in the node pool will be created in this cloud server group. After a cloud server group is associated with a node pool, the number of nodes in the node pool cannot exceed the number of cloud servers that can be added to the cloud server group, or the node pool cannot be scaled out. NOTE: After a cloud server group is associated with a node pool, the cloud servers added to the cloud server group will be distributed in strict accordance with the affinity policy and the maximum number of nodes in the node pool will be limited. The anti-affinity capabilities are available during cloud server creation on ECS. If your goal is to enhance service reliability by distributing cloud servers across different hosts and you do not want the number of nodes to be restricted by cloud server groups, you are advised not to associate cloud server groups with any node pools. A cloud server group can be disassociated from the node pool. After the change, the existing nodes will remain in the original cloud server group, and no new nodes will be added to the cloud server group. If the node pool is empty, you can associate a new cloud server group with the node pool or change the associated cloud server group. Options: If this parameter is not specified or left blank, the cloud server group will be disassociated from the node pool. A cloud server group ID: The cloud server group associated with the node pool will be changed to a specified one. Default value: N/A
