Parameter	Mandatory	Type	Description
name	No	String	Node name. Note Enter 0 to 56 characters starting with a letter and not ending with a hyphen (-). Only lowercase letters, digits, and hyphens (-) are allowed. If no node name is specified, the system automatically generates a node name in the format of Cluster Name-*****.
labels	No	Object	CCE node label (not the native Kubernetes label). Labels are used to select objects that meet certain criteria. A label is a key-value pair. Example: "labels": { "key" : "value" } Note Users can not use this field to define the native Kubernetes labels.

Example: "annotations": { "key1" : "value1", "key2" : "value2" } Note Users can not use this field to define the native Kubernetes labels. Annotations are not used to identify or select objects. The metadata in Annotations may be small or large, structured or unstructured, and may include characters that are not allowed in labels.

**Table 5** Data structure of the **spec** field¶

dataVolumes	Array of Volume object	Data disk parameters of the node.
storage	Storage object	Disk initialization management parameter. This parameter is complex to configure. For details, see Attaching Disks to a Node. If this parameter retains its default, disks are managed based on the DockerLVMConfigOverride (discarded) parameter in extendParam. This parameter is supported by clusters of version 1.15.11 and later. Note If a node specification involves local disks and EVS disks at the same time, do not retain the default value of this parameter to prevent unexpected disk partitions.
publicIP	publicIP object	EIP parameters of a node.
nodeNicSpec	nodeNicSpec object	Description about the node NIC.
count	Integer	Number of nodes to be created in a batch. The value must be a positive integer greater than or equal to 1. Note This parameter can be set to 0 for a node pool.
billingMode	Integer	Billing mode of a node. Note This field is not supported for the current version.
userTags	Object	The format is key-value pair. It is recommended that you use TMS's predefined tag function to add the same tag to different cloud resources. The tag key can consist of only uppercase letters, lowercase letters, digits, hyphens (-), underscores (_), and Unicode characters. The tag value can contain only uppercase letters, lowercase letters, digits, hyphens (-), underscores (_), and at signs (@). Example: "userTags": [ { "key": "tag1", "value": "aaaa" }, { "key": "tag2", "value": "bbbb" }]
k8sTags	Object	The format is key-value pair. The number of key-value pairs cannot exceed 20. Key: Enter 1 to 63 characters starting with a letter or digit. Only letters, digits, hyphens (-), underscores (_), and periods (.) are allowed. A DNS subdomain can be prefixed to a key and contain a maximum of 253 characters. Example DNS subdomain: example.com/my-key Value: The value can be left blank or a string of 1 to 63 characters starting with a letter or digit. Only letters, digits, hyphens (-), underscores (_), and periods (.) are allowed in the character string. Note If a node is created using a node pool, a label whose key is cce.cloud.com/cce-nodepool is automatically added to the node, and the label value is the node name. Example: "k8sTags": { "key": "value" }
taints	Object	You can add taints to created nodes to configure anti-affinity. Each taint contains the following parameters: Key: A key must contain 1 to 63 characters starting with a letter or digit.

Value: A value must start with a letter or digit and can contain a maximum of 63 characters, including letters, digits, hyphens (-), underscores (_), and periods (.). Effect: Available options are NoSchedule, PreferNoSchedule, and NoExecute. Example: "taints": [{ "key": "status", "value": "unavailable", "effect": "NoSchedule" }, { "key": "looks", "value": "bad", "effect": "NoSchedule" }]
ecsGroupId	String	ECS group ID. If this parameter is specified, the node is created in the specified ECS group. Note This parameter is not supported when you add a node to a node pool or use CCE Turbo cluster.
