[ECS][IMPORT] opentelekomcloud_compute_instance_v2 seams to not work with multiple Subnet in VPC

[Moep90]

Version

$ terraform --version
Terraform v0.15.0
on linux_amd64
+ provider registry.terraform.io/opentelekomcloud/opentelekomcloud v1.23.9

Import doesnt work with having a SINGLE interface on the ECS but having multiple VPC-Subnet in the VPC where I try to import it.

Network

I have somethink like this as Network:

resource "opentelekomcloud_vpc_v1" "vpc_v1" {
  name = var.vpc_name
  cidr = var.vpc_cidr
}

resource "opentelekomcloud_vpc_subnet_v1" "subnet_1" {
  name   = var.subnet_name_1
  cidr   = var.subnet_cidr_1
  vpc_id = opentelekomcloud_vpc_v1.vpc_v1.id

  gateway_ip    = var.subnet_gateway_ip_1
  ntp_addresses = "10.100.0.33,10.100.0.34"
}

resource "opentelekomcloud_vpc_subnet_v1" "subnet_2" {
  name   = var.subnet_name_2
  cidr   = var.subnet_cidr_2
  vpc_id = opentelekomcloud_vpc_v1.vpc_v1.id

  gateway_ip    = var.subnet_gateway_ip_2
  ntp_addresses = "10.100.0.33,10.100.0.34"
}

resource "opentelekomcloud_vpc_subnet_v1" "subnet_3" {
  name   = var.subnet_name_3
  cidr   = var.subnet_cidr_3
  vpc_id = opentelekomcloud_vpc_v1.vpc_v1.id

  gateway_ip    = var.subnet_gateway_ip_3
  ntp_addresses = "10.100.0.33,10.100.0.34"
}

ECS Instance

The instance looks like:
I double checked that the Instances is (for real) only connected to ONE network...

resource "opentelekomcloud_compute_instance_v2" "ecs_instance" {
  name      = "boot-from-volume"
  flavor_id = var.flavor_id
  key_pair  = var.key_pair
  image_id  = var.image_id

  network {
    id        = opentelekomcloud_vpc_subnet_v1.subnet_2.id
    fixed_ip_v4 = "<fixed_ip_v4>"
  }

}

Import try

@outcatcher

$ terraform import opentelekomcloud_compute_instance_v2.ecs_instance xxxxxxxxxxxxxxx-yyyyyyyyyyyyyyy
opentelekomcloud_compute_instance_v2.ecs_instance: Importing from ID "xxxxxxxxxxxxxxx-yyyyyyyyyyyyyyy"...

@Moep90 We query ECSv2 instance and we have only vpc_id in response.
And the problem is when you create a VPC with 3 Subnets it creates 3 Networks with same name where Network name == VPC ID.

[Moep90]

@lego963 Then the OTC may would open an internal issue about it?
its not suitable to NOT be able to import ECSv2 instances.
I guess to add an subnet into the response is a possible thing.

[lego963]

@Moep90 sorry, I'm wrong and we will fix it

[Moep90]

No testing regarding importing of resources?

[lego963]

@Moep90 we've tested import with multiple networks and it was green. We will release soon new version.

[Moep90]

@lego963 manually I guess?
Why not automate import tests as well?

[lego963]

Our acceptance tests for resources/data_sources and imports

[Moep90]

ah ok, didn't found them...sorry!
great! Thank you!
