Descripiton

subnetId

Yes

ID of the Subnet to which the SNatRule 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.

floatingIpId

Yes

User EIP ID

Type: HuaweiCloud.VPC.EIP.Id

Value Description: Supports the ID of an existing or new public elastic IP address.

Suggestion: 1. Use the get_attribute function to obtain the ID of the elastic public IP address created by the template. 2. On the public elastic IP address page (https://console.huaweicloud.com/vpc?&locale=en-us), obtain the ID of the created IP address.

natGatewayId

Yes

ID of the NatGateWay

Type: string

Value Description: Obtains the natgateway ID from the NAT service or put snatrule in the natgateway 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 obtain the NatGateWay ID.
