labels	No	dict	labels of the created node Value Description: Customize the value, 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: Customize the value. Value Constraint: The script you specify here will be executed before K8S software is installed. Note that if the script is incorrect, K8S 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: Customize the value, 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.
instances	Yes	integer	Number of created nodes Value Description: Customize the value. 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: Customize the value, for example, {"volumeType":"SATA","size":40}. Suggestion: Customize the value.
os	No	string	os of the created node Value Description: ["EulerOS 2.2", "CentOS 7.4"] Value Constraint: Customize the value. If this parameter is left blank, EulerOS 2.2 is used by default. Suggestion: The options are EulerOS 2.2 and CentOS 7.4.
nodePasswd	No	password	Password of the node root user Value Description: Customize the value. Value Constraint: 1. The parameter must be written into inputs and set using the get_input function. 2.

Suggestion: You are advised to use the get_input function to obtain the value and avoid plaintext passwords to ensure security.
flavor	Yes	Cloud.CCE.Node.Flavor.Name	Container node specification Value Description: ID of the system flavor of the ECS to be created. You are advised to set this parameter in get_input mode. Suggestion: Select the node specification during node creation on the CCE console. In the node template, you can set the inputs to specify the node specification.
sshKeyName	Yes	Cloud.ECS.KeyPair.Name	Key pair used for logging in to a node, which needs to be kept properly Value Description: It must be created on the ECS console in advance. Value Constraint: sshkeyName and nodePasswd cannot be used at the same time. 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. Obtain the information on the ECS console and then enter the information accordingly.
annotations	No	dict	Annotations of Node Value Description: Customize the value, for example, {"app": "aos"}. Suggestion: You can enter multiple key-value pairs.
