Property	Required	Type	Description
dataVolumes	Yes	CCE.DataVolume	Data disk of the created node 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/eu/tr-aos/datatypes-cce-datavolume.html.
availabilityZone	Yes	HuaweiCloud.ECS.AvailabilityZone.Name	AZ where the node is located Value Description: AZ where the to-be-created ECS is located. The name of the AZ needs to be specified, for example, cn-north-1a. For details, see the Regions and Endpoints. Value Constraint: The value varies depending on the belonged 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 AZ of each region, visit https://developer.huaweicloud.com/intl/en-us/endpoint.
name	No	string	Name of the created node 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	HuaweiCloud.ECS.KeyPair.PublicKey	Public key of the key pair in the duration-based billing mode 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	string	Node post-installation script 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	dict	Labels of the created node Value Description: Supports customization, for example, {"key": "aos","value": "app","scope":[1,2]}. Suggestion: Enter the key, value, and scope as required.
preInstall	No	string	Node pre-installation script Value Description: Supports customization. Value Constraint: The script you specify here will be executed before K8S 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	CCE.PublicIP	Virtual IP address of the created node Value Description: Supports customization, for example, {"eip":{"bandwidth:{" shareType":PER}, 5_sbgp"}}. Value Constraint: Only one elastic IP address can be defined for each node. Suggestion: Customize the value. For details, visit https://support.huaweicloud.com/eu/tr-aos/datatypes-cce-publicip.html.
instances	Yes	integer	Number of the created nodes Value Description: Supports customization. The value ranges from 1 to 50. Value Constraint: {u'in_range': [1, 50]} Suggestion: Set the value based on specifications and requirements.
rootVolume	Yes	ECS.RootVolume	System disk of the created node Value Description: Supports customization, for example, {"volumeType":"SATA","size":40}. Suggestion: Customize the value. For details, visit https://support.huaweicloud.com/eu/tr-aos/datatypes-ecs-rootvolume.html.
os	No	string	os of the created node Value Description: ["EulerOS 2.2", "CentOS 7.4"] Value Constraint: Customize the value. This parameter is EulerOS 2.2 by default. Suggestion: Supports EulerOS 2.2 and CentOS 7.4.
nodePasswd	No	password	Password of the nodes' root Value Description: Supports customization. Value Constraint: 1. The parameter must be written into inputs and set using the get_input function. 2. The value cannot be empty or a weak password. Enter 8 to 26 characters. Only uppercase and lowercase letters, digits, and special characters !@$%^-_=+[{}]:,./? are allowed. The value must contain at least two types of characters. 3. 3. Using both sshkeyName and nodePasswd is not supported Suggestion: You are advised to use the get_input function to obtain the value and avoid plaintext passwords to ensure security.
flavor	Yes	HuaweiCloud.CCE.Node.Flavor.Name	Container node specifications 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/eu/productdesc-ecs/ecs_01_0014.html. You are 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	Yes	HuaweiCloud.ECS.KeyPair.Name	Key pair used for logging in to a node, which needs to be kept properly Value Description: Must be created on the ECS console in advance. Value Constraint: Using both sshkeyName and nodePasswd is not supported. Suggestion: 1. You are advised to use the get_input function to assign values 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	dict	Annotations of Node Value Description: Supports customization, for example, {"app": "aos"}. Suggestion: Enter multiple key-value pairs to customize the value.
