You can add taints to created nodes to configure anti-affinity. A maximum of 20 taints can be added. Each taint contains the following parameters:

• Key: A key must contain 1 to 63 characters starting with a letter or digit. Only letters, digits, hyphens (-), underscores (_), and periods (.) are allowed. A DNS subdomain name can be used as the prefix of a key.

• 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.

  When creating a node, you can specify the initial value for this parameter and this field is not returned during query. In using node pools, the initial value can be specified 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"
}]

k8sTags

Map<String,String>

Defined in key-value pairs. A maximum of 20 key-value pairs are allowed.

• 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 contain 1 to 63 characters that start with a letter or digit. Only letters, digits, hyphens (-), underscores (_), and periods (.) are allowed in the character string.

  When creating a node, you can specify the initial value for this parameter and this field is not returned during query. In using node pools, the initial value can be specified in the node template and this field is returned during query. In other scenarios, this field is not returned during query.

Example:

"k8sTags": {
  "key": "value"
}

ecsGroupId

String

ECS group ID. If this parameter is configured, nodes will be created in the specified ECS group.

dedicatedHostId

String

ID of the DeH to which the node is scheduled.

userTags

Array of UserTag objects

Cloud server tag. The key of a tag must be unique. The maximum number of custom tags supported by CCE depends on the region and cannot exceed 8.

When creating a node, you can specify the initial value for this parameter and this field is not returned during query. In using node pools, the initial value can be specified in the node template and this field is returned during query. In other scenarios, this field is not returned during query.

runtime

Runtime object

Container runtime:

• Clusters of v1.25 or earlier: docker.

• Clusters of v1.25 or later: Container runtime varies with the OS. 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

Custom initialization flag, which is left blank 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:

1. Create a node and add parameter "initializedConditions": ["CCEInitial", "CustomedInitial"].

2. After custom initialization is complete, CCE will call a Kubernetes API (for example, PATCH /v1/nodes/{node_ip}/status) to update the node conditions by adding two labels of types CCEInitial and CustomedInitial and setting the status to True, as shown in the following:

status:
  conditions:
  - type: CCEInitial
    status: 'True'
  - type: CustomedInitial
    status: 'True'

1. CCE polls status.Conditions of nodes to check whether there are conditions of types CCEInitial and CustomedInitial. If such conditions exist and the status is True, the node initialization is complete and the initialization taint is removed.

2. initializedConditions allows you to configure a timeout period during node creation. For example, "initializedConditions": ["CCEInitial:15m", "CustomedInitial:15m"] indicates that the timeout period is 15 minutes. After the timeout period is reached, the initialization conditions will be automatically ignored and the initialization taint will be removed when CCE polls the node.

• Use only letters and digits. Max. characters: 20.

• Max. flags: 2.

• The unit of the timeout period is minute (m).

extendParam

NodeExtendParam object

Extended parameters for creating a node.

serverEnterpriseProjectID

String

Enterprise project ID of a server. CCE does not support features provided by EPS. This field is used only for synchronizing enterprise project IDs of servers.

To create a node or node pool, you can specify an existing enterprise project for it. If this field is left blank, it inherits the enterprise project attributes of the cluster that runs the node or node pool.

When updating a node pool, any configuration modifications you made will apply only to new nodes. You need to modify the enterprise projects of existing nodes on the EPS console.

If no value is specified during the update, this field will not be updated.

If this parameter is left blank, the cluster enterprise project is returned.

dockerBaseSize

Integer

Available disk space of a single container on a node, in GB. This parameter has been discarded. Use containerBaseSize.

If this parameter is left blank or is set to 0, the default value is used. In Device Mapper mode, the default value is 10. In OverlayFS mode, the available space of a single container is not limited by default, and the dockerBaseSize setting takes effect only on nodes running EulerOS/Huawei Cloud EulerOS 2.0 in clusters of the new versions.

For details about how to allocate the space for the container runtime, see Data Disk Space Allocation.

When Device Mapper is used, it is recommended that dockerBaseSize be set to a value less than or equal to 80 GB. If the value is too large, the container runtime may fail to be started due to long initialization. If there are special requirements for the container disk space, you can mount an external or local storage device.

For details about how to allocate the space for the container runtime, see Data Disk Space Allocation.

When Device Mapper is used, it is recommended that containerBaseSize be set to a value less than or equal to 80 GB. If the value is too large, the container runtime may fail to be started due to long initialization. If there are special requirements for the container disk space, you can mount an external or local storage device. In new versions, the Device Mapper mode is used only by BMSs in the same resource pool and is being discarded.

• Supported proportions are {"1":128, "2":92, "4":92, "8":32, "16":16, "28":9}. That is, if 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 for two queues.

• 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

String

• ENI pre-binding thresholds. Example setting:

"0.3:0.6"

• Low threshold (L): determines the minimum number of pre-bound ENIs (Min). Formula: Min = Total number of ENIs of the node x L

• Number of ENIs bound to a BMS node (B) and number of ENIs being used by pods (U): U + Min < B < U + Max

• If the number of pre-bound ENIs on a BMS node is smaller than the minimum allowed, the system will bind more ENIs to make the numbers equal.

• If the number of pre-bound ENIs on a BMS node is larger than the maximum allowed, the system periodically unbinds ENIs (about every 2 minutes) to make the numbers equal.

• 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.
