CCE.NodePool

Element Description

The CCE.NodePool element is used to deploy Kubernetes node resources at the Huawei PaaS layer. Deploying this type of resources enables users to orchestrate Huawei cloud resources on nodes, providing more powerful functions.

Element Properties

**Table 1** Property description
Property	Required	Description
dataVolumes	Yes	Data disk of the created node Type: CCE.DataVolume array Value Description: Supports customization, for example, [{"volumeType":"SATA","size":100}]. Value Constraint: Array format. Currently, only one object is supported. Suggestion: Customize the value. For details, visit https://support.huaweicloud.com/intl/en-us/tr-aos/datatypes-cce-datavolume.html.
availabilityZone	Yes	AZ where the node is located Type: HuaweiCloud.ECS.AvailabilityZone.Name Value Description: Indicates the AZ where the to-be-created ECS is located. The name of the AZ needs to be specified, for example, cn-north-1a. See the Regions and Endpoints. Value Constraint: The value varies depending on the region. For details, visit https://developer.huaweicloud.com/intl/en-us/endpoint. Suggestion: 1. Use the get_input function to pass this parameter. Its value can then be automatically selected when you create a stack on the AOS console. 2. For details about the AZs of each region, visit https://developer.huaweicloud.com/intl/en-us/endpoint.
name	Yes	Name of the created node Type: string Value Description: Supports customization. Value Constraint: The value contains 4 to 32 characters and must start with a lowercase letter. Only lowercase letters, digits, and underscores (_) are allowed. Suggestion: Customize the value. Generally, the stack name is used as the node name.
publicKey	No	Public key of the key pair. For periodic nodepool, this field is mandatory. Type: HuaweiCloud.ECS.KeyPair.PublicKey Value Description: Selects an existing public key. Suggestion: Use the get_input function to pass this parameter. Its value can then be automatically selected based on parameter sshKeyName when you create a stack on the AOS console.
postInstall	No	Node post-installation script Type: string Value Description: Supports customization. Value Constraint: The script you specify here will be executed after Kubernetes software is installed. Suggestion: The script is usually used to modify container parameters.
labels	No	Labels of Node Type: CCE.Labels array Value Description: Supports customization, for example, {"app": "aos"}. Suggestion: Enters multiple key-value pairs to customize the value.
clusterId	No	ID of the cluster to which a resource belongs. Type: HuaweiCloud.CCE.Cluster.Id Value Description: ID of an existing or new container cluster. Value Constraint: The value must satisfy the UUID rule and support a maximum of 64 characters. Suggestion: 1. Enter the cluster ID. Specifically, log in to the CCE console, and choose Resource Management > Clusters. Click the target cluster, and you can then obtain its cluster ID. 2. Connect to the cluster object and use the get_reference function to obtain the cluster ID. Connect to the cluster object and use the get_reference function to automatically obtain the value.
preInstall	No	Node pre-installation script Type: string Value Description: Supports customization. Value Constraint: The script you specify here will be executed before Kubernetes software is installed. Note that if the script is incorrect, Kubernetes software may not be installed successfully. Suggestion: The script is usually used to format data disks.
publicIp	No	Virtual IP address of the created node Type: CCE.PublicIP Value Description: Supports customization, for example, {"eip":{"bandwidth:{"shareType":PER}, 5_sbgp"}}. Default Value: {} Value Constraint: Only one elastic IP address can be defined for each node. Suggestion: Customize the value. For details, visit https://support.huaweicloud.com/intl/en-us/tr-aos/datatypes-cce-publicip.html.
instances	Yes	Number of created nodes Type: integer Value Description: Supports customization. The value ranges from 1 to 50. Default Value: 1 Value Constraint: {u'in_range': [1, 50]} Suggestion: Set the value based on specifications and requirements.
rootVolume	Yes	System disk of the created node Type: ECS.RootVolume Value Description: Supports customization, for example, {"volumeType":"SATA","size":40}. Default: {u'volumeType': u'unset', u'size': 40} Suggestion: Customize the value. For details, visit https://support.huaweicloud.com/intl/en-us/usermanual-iaas/en-us_topic_0040259342.html.
os	No	OS of Node Type: string Value Description: ["EulerOS 2.2", "CentOS 7.4"] Default: EulerOS 2.2 Value Constraint: {u'valid_values': [u'CentOS 7.4', u'EulerOS 2.2']}
nodePasswd	No	Password of nodes' root Type: password Value Description: Supports customization. Value Constraint: 1. The parameter must be written into inputs and set using the get_input function. 2. Enter 8 to 26 characters. Only letters, digits, and special characters !@$%^-_=+[{}]:,./? are allowed. The value must contain at least two types of characters and must not be a weak password. Suggestion: You are advised to use the get_input function to obtain the value and avoid plaintext passwords to ensure security.
flavor	Yes	Container node specifications Type: HuaweiCloud.CCE.Node.Flavor.Name Value Description: System flavor ID of the ECS to be created. For example, c1.medium indicates 1 vCPU \| 1 GB, and c2.large indicates 2 vCPU \| 4 GB. For details about the available flavors, see ECS Specifications at https://support.huaweicloud.com/intl/en-us/productdesc-ecs/ecs_01_0014.html. It is advised to use the get_input function to pass this parameter. Suggestion: Select the node specification during node creation on the CCE console. In the node template, you can set inputs to specify the node specification.
sshKeyName	No	Key pair used for logging in to a node, which needs to be kept properly Type: HuaweiCloud.ECS.KeyPair.Name Value Description: Must be created on the ECS console in advance. Suggestion: 1. You are advised to use the get_input function to define the parameter so that you can select a value when using the template. 2. Query information on the ECS page and then enter such information accordingly.
annotations	No	Annotations of Node Type: dict Value Description: Supports customization, for example, {"app": "aos"}. Suggestion: Enter multiple key-value pairs to customize the value.
