This API is used to create a node pool in a specified cluster.

URI

POST /api/v3/projects/{project_id}/clusters/{cluster_id}/nodepools

Table 1 <cce_02_0354__table2027961241820> describes the parameters of the API.

**Table 1** Parameter description
Parameter	Mandatory	Description
project_id	Yes	Project ID. For details about how to obtain the project ID, see `How to Obtain Parameters in the API URI <cce_02_0271>`.
cluster_id	Yes	Cluster ID. For details about how to obtain the cluster ID, see `How to Obtain Parameters in the API URI <cce_02_0271>`.

Request

Request parameters:

Table 2 <cce_02_0354__table13796145119241> and Table 3 <cce_02_0354__table1644211019> describe the request parameters.

**Table 2** Parameters in the request header
Parameter	Mandatory	String	Description
Content-Type	Yes	String	Message body type (format). Default: application/json
X-Auth-Token	Yes	String	Requests for calling an API can be authenticated using either a token or AK/SK. If token-based authentication is used, this parameter is mandatory and must be set to a user token. For details on how to obtain a user token, see `API Usage Guidelines <cce_02_0344>`.

**Table 3** NodePool structure
Parameter	Mandatory	Type	Description
kind	Yes	String	API type, which is fixed at NodePool.
apiVersion	Yes	String	API version, which is fixed at v3.
metadata	Yes	`metadata <cce_02_0354__table13456192212>` object	Metadata of the node pool.
spec	Yes	`spec <cce_02_0354__table620623542313>` object	Parameters of the node pool.

**Table 4** Data structure of the **metadata** field
Parameter	Mandatory	Type	Description
name	Yes	String	Node pool name. Naming rule: Enter 1 to 50 characters that starts with a lowercase letter and cannot end with a hyphen (-). Lowercase letters, digits, and hyphens (-) are allowed. The value cannot be DefaultPool.

**Table 5** Data structure of the **spec** field
Parameter	Mandatory	Type	Description
type	No	String	Node pool type. If this parameter is left blank, the value vm is used by default. vm: ECS ElasticBMS: BMS. This value is valid in CCE Turbo cluster.
nodeTemplate	Yes	`nodeTemplate <cce_02_0354__table3150105216225>` object	Parameters of the node pool template. If az is set to random, when you create a node pool or update the number of nodes in a node pool, a scaling task is triggered. The system selects an AZ from all AZs where scaling is allowed to add nodes based on priorities. AZs with a smaller number of existing nodes have a higher priority. If AZs have the same number of nodes, the system selects the AZ based on the AZ sequence. Example: Creating nodes in a node pool for the first time: Assume that AZ 1, AZ 2, and AZ 3 have available resources. These AZs have the same priority because they have no existing nodes. In this case, AZ 1 is selected by sequence to create all nodes to be added. Adding nodes to a node pool that already has nodes: Assume that the node pool has 1 node in AZ 1, 3 in AZ 2, and 2 in AZ 3, and that resources in AZ 1 have been sold out. Only AZ 2 and AZ 3 are available for scaling. In this case, AZ 3 has a higher priority than AZ 2 because AZ 3 has less nodes. Therefore, all nodes to be added will be created in AZ 3. Assume that the node pool has 1 node in AZ 1, 2 in AZ 2, and 2 in AZ 3, and that resources in AZ 1 have been sold out. Only AZ 2 and AZ 3 are available for scaling. In this case, AZ 2 and AZ 3 have the same priority because they have the same number of nodes. Therefore, all nodes to be added will be created in AZ 2.
initialNodeCount	Yes	Integer	Expected number of nodes in this node pool. The value cannot be greater than the maximum number of nodes allowed for the cluster.
autoscaling	No	`autoscaling <cce_02_0354__table1472543502018>` object	Auto scaling parameters.

Currently, only the evs, hdd, and ssd are supported. lvType: type of a logic volume. Currently, the value can be linear or striped. dockerThinpool: Docker space size, for example, vgpaas/60%VG. kubernetesLV: kubelet space size, for example, vgpaas/20%VG.
publicKey	No	String	Public key of the node. Used when creating a key pair.
nicMultiqueue	No	String	ENI queue settings, the default setting is: `"[{\"queue\":4}]"` queue indicates the number of ENI queues. Supported proportions are {"1":128, "2":92, "4":92, "8":32, "16":16, "28":9}. That is, there is one queue, a maximum of 128 ENIs can be bound. If there are two queues, a maximum of 92 ENIs can be bound. A larger number of ENI queues indicates higher performance but fewer ENIs can be bound. The queue settings cannot be changed after the node pool is created.
nicThreshold	No	String	ENI pre-binding thresholds, the default setting is: `"0.3:0.6"` The first decimal place indicates the low threshold. Formula: Minimum number of pre-bound ENIs = Min (128 x Low threshold, Maximum number of ENIs that can be bound to the queue) The second decimal place indicates the high threshold. Formula: Maximum number of pre-bound ENIs = Min (128 x High threshold, Maximum number of ENIs that can be bound to the queue) The high and low thresholds of the number of pre-bound ENIs are restricted by the maximum number of ENIs that can be bound to a queue. ENIs bound to a BMS node = Number of ENIs currently used by pods + Number of pre-bound ENIs CCE keeps binding ENIs to a BMS node to ensure that the minimum number of ENIs is always reached. (Min. pre-bound ENIs <= Number of pre-bound ENIs + Number of ENIs currently used by pods) At every 2 minutes, CCE releases ENIs pre-bound to a BMS node to ensure that the maximum number of ENIs will not be exceeded. (Max. pre-bound ENIs >= Number of pre-bound ENIs + Number of ENIs currently used by pods) Both the thresholds are one-decimal-place values ranging from 0.0 to 1.0. The low threshold must be smaller than or equal to the high one. This field can be configured only for BMS nodes in a CCE Turbo cluster. Pre-binding ENIs can speed up workload creation but occupies IP addresses.

Parameter	Mandatory	Type	Description
subnetId	No	String	Network ID of the subnet to which the NIC belongs.
fixedIps	No	Array of strings	The IP address of the primary NIC is specified by fixedIps. The number of IP addresses cannot be greater than the number of created nodes. fixedIps and ipBlock cannot be specified at the same time.
ipBlock	No	String	CIDR format of the IP address segment. The IP address of the created node falls in this IP address segment. fixedIps and ipBlock cannot be specified at the same time.

**Table 16** Data structure of the **autoscaling** field
Parameter	Mandatory	Type	Description
enable	No	Boolean	Whether to enable auto scaling.
minNodeCount	No	Integer	Minimum number of nodes after a scale-down if auto scaling is enabled.
maxNodeCount	No	Integer	Maximum number of nodes after a scale-up if auto scaling is enabled. The value of this parameter must be greater than or equal to that of minNodeCount and does not exceed the maximum number of nodes for the cluster.
scaleDownCooldownTime	No	Integer	Interval during which nodes added after a scale-up will not be deleted, in minutes.
priority	No	Integer	Node pool weight. A higher weight indicates a higher priority in scale-up.

**Table 17** Data structure of the nodeManagement field
Parameter	Mandatory	Type	Description
