[RDS] Asking for subnet_id but waiting network_id instead

[antonin-a]

Hi there,

When trying to create a RDS instance using https://registry.terraform.io/providers/FlexibleEngineCloud/flexibleengine/latest/docs/resources/rds_instance_v3

"Subnet_id" argument is asked : https://registry.terraform.io/providers/FlexibleEngineCloud/flexibleengine/latest/docs/resources/rds_instance_v3#subnet_id

But in fact it is waiting for 'network_id'

(Looks similar to https://github.com/FlexibleEngineCloud/terraform-provider-flexibleengine/issues/176) regards

Hello,

I'm using the RDS instance v3 on my project, but the subnet_id is not related to network_id.

Here is a code I'm using:

### netwoking module
resource "flexibleengine_vpc_subnet_v1" "subnet_" {
  for_each = {
    for instance in local.vpc_configuration : "${var.BU}${instance.subnet_name}" => instance
  }

  name = "${var.BU}${each.value.subnet_name}"
  cidr = each.value.subnet_cidr
  gateway_ip = each.value.subnet_gw
  vpc_id = flexibleengine_vpc_v1.vpc_["${var.BU}${each.value.vpc_name}"].id
  primary_dns = "100.125.0.41"
  secondary_dns= "100.126.0.41"
}

output "**db_subnet**" {
  value = flexibleengine_vpc_subnet_v1.subnet_["${var.BU}_priv_database"].id
}

### main vars
subnet_id = module.networking.db_subnet // it will get the value from the output "**db_subnet**"

### rds module
resource "flexibleengine_rds_instance_v3" "RDS_instance" {
  name              = "${var.BU}_${var.type}_rds_instance"
  flavor            = var.enable-ha ? var.db_flavor_ha : var.db_flavor
  ha_replication_mode = var.enable-ha ? "async" : ""
  availability_zone = var.enable-ha ? ["eu-west-0b","eu-west-0a"] :  ["eu-west-0b"] 
  security_group_id = var.security_group_database
  vpc_id            = var.db_vpc
  **subnet_id         = var.subnet_id**

  db {
    password = var.db_password
    type     = "MySQL"
    version  = "8.0"
    port     = "3306"
  }
  volume {
    type = "COMMON"
    size = 100
  }
  backup_strategy {
    start_time = "08:00-09:00"
    keep_days  = 3
  }
  lifecycle {
    ignore_changes = [
     db
    ]
  }
}

If you have all code in the same folder you can replace inside the rds creation var.subnet_id with 'flexibleengine_vpc_subnet_v1.your_subnet_name.id'

@antonin-a For historical reasons, there are several confusing concepts in subnet resource/service, I will try to explain them:

• ID: Like other resources, the ID represents the resource's UUID. ID and network_id have the same value;
• network_id: The concept of network is derived from openstack, which will be no longer used;
• subnet_id: The ID of ipv4 subnet belonging to the subnet service.

so, When other services need to refer to subnets, we recommend using subnet_id to represent the subnet service, and the value is flexibleengine_vpc_subnet_v1.subnet-1.id.

In order to distinguish subnet_id parameter from subnet_id attribute in the subnet, we plan to change subnet_id attribute to ipv4_subent_id
