Table 3 NodePool structure

Parameter

Mandatory

Type

Description

kind

Yes

String

API type, which is fixed at NodePool.

Yes

String

API version, which is fixed at v3.

metadata

Parameters of the node pool.

Table 4 Data structure of the metadata field

Parameter

Mandatory

Type

Description

name

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 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.

"[{\"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.

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.

  • Pre-binding ENIs can speed up workload creation but occupies IP addresses.
