Element Properties

**Table 1** Property Description
Property	Required	Descripiton
subnetId	Yes	ID of the Subnet to which the NatGateWay belongs Type: HuaweiCloud.VPC.Subnet.Id Value Constraint: The value must satisfy the UUID rule and support a maximum of 64 characters. Suggestion: 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. Connect to a subnet object and use the get_reference function to the ID of the newly created subnet.
flavor	Yes	NatGateWay specification Type: string Default: small Value Constraint: The NAT specification and definition must be complied with Suggestion: Valid value:[small middle large xlarge]
vpcId	Yes	ID of the VPC to which the NatGateWay belongs Type: HuaweiCloud.VPC.VPC.Id Value Description: Supports the use of an existing or new VPC ID. To use a new VPC ID, you need to define the VPC object in the template and establish the dependency relationship. You are advised to drag the object to the VPC to automatically establish the dependency relationship. Value Constraint: The value must satisfy the UUID rule and support a maximum of 64 characters. Suggestion: 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. Use the get_reference function to reference a VPC.VPC element created by the current stack. The group ID can then be automatically specified when you use the designer to create a dependency on the VPC.VPC element. Obtain the ID of the created VPC on the VPC console at https://console.huaweicloud.com/vpc?&locale=en-us.
description	No	NatGateWay instance Type: string Value Description: Supports customization. Value Constraint: The value contains a maximum of 255 characters, including letters and digits. Suggestion: Customize the value.
name	Yes	Name of the NatGateWay instance Type: string Value Description: Supports customization, for example, my-nat. Value Constraint: The value must contain 1 to 64 characters and meet the following requirement: [-_a-zA-Z0-9]$. Suggestion:* Customize the value.
